[VX800] Samsung NC20 installation problem(viafb problem)

[George Varghese]

Bug also affects the installed (non Live System) Version of Ubuntu 10.04 i386 and amd64. Lucid Live System (10.04 Beta1 and Beta2) running properly.

Binary package hint: ubiquity

First, thanks and greetings to all who contribute to this wonderful community :-)

I guess the package in problem is is Ubiquity. But I am not sure.
I bought this new netbook - Samsung NC 20. More info at
http://www.sammynetbook.com/samsung-nc20

# Chipset: VIA VX800 Unified Digital Media IGP Chipset

I tried to install Ubuntu 9.04 from after downloading it from http://www.ubuntu.com/getubuntu/download a couple of days ago (week of 8th May 2009). Since I do not have a CD rom drive, i used UNetBooting to create a bootable USB from the ISO image. While booting I got the options menu. I chose default. I could see the Ubuntu logo with a horizontal bar for some time. Then the screen blurred. I could see some blurred image of Ubuntu on the screen. I had to stop installation there. Then I tried to give boot switches in the first(and only) menu. I tried vga=771 and fb=off. But they did not work. The screen resolution is 1280x800 for which I do not see a number. From web I could get a number of 640x400, that also did not work. The same thing happened with Xubuntu 9.04. Then I changed to Ubuntu 8.04LTS. This time I could get the windows (is it Xwindows?) I clicked on install. It worked and I could take it through complete installation. But now the WLAN is not detected (it could be another bug).

This bug is about getting the correct display during installation boot. Could you do anything? Please let me know how I could help.

People are following this up but AFAK there is not bug report filed on this problem.

It's xorg's responsibility to arrange for a usable display.

[Bryce Harrington (bryce)]

Hi geovar,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[George Varghese (geovar)]

Thanks Bryce. Attached yo will find lspci output and Xorg.0.log
I did not make any local changes to Xorg.conf.
These are taken from my working set up. i.e. 8.04 LTS installed
in my Samsung NC20. This did not fail while installation.

[Martin Olsson (mnemo)]

It would be valuable to have the xorg.log from jaunty as well even though I realized that would be pretty hard to get. When you have USB booted into 9.04 jaunty and you see a distorted screen that looks a bit like Ubuntu running (not the usplash progress bar), is it then possible to press CTRL-ALT-F1 to get to a text based terminal? If so, maybe you can install the ssh package from there and scp the xorg.log to another computer? Also, I suspect jaunty tries to use the -openchrome driver on your machine so if you switch to vesa (the driver you used on 8.04) it might work better even though I'm not sure how to do that if the screen has graphics corruption.

[Bartosz Kosiorek (gang65)]

Hi.
Your card is not successfuly detected. This bug was resolved in the latest openchrome version.
Please build the latest (trunk) revision.

All was described at:
https://help.ubuntu.com/community/OpenChrome

[George Varghese (geovar)]

I understand that my card is not supported. I can download the
latest openchrome version and build it once my installation is
successful. But here, I am not able to install the latest Ubuntu
9.04 available from the website. When a card is not detected, I
was expecting that it might be possible to get it working with
some safe resolution (I guess the technical term used is safe
mode or vga=771). It would greatly help new users (and spoilt
users like me) to have the GUI based installation. It seems that
there is a fix, which is undergoing testing now and will be
included in the official release of Ubuntu later. Until then I
have to live with the trunk version. If that is the case, it is
perfectly fine.

[Bartosz Kosiorek (gang65)]

Hi George.
So as I understand the Ubuntu 9.04 Jaunty works fine on your hardware with Latest trunk Openchrome revision?

The xserver-xorg-video-openchrome package from Karmic should also resolve your problems.
You can download it from:
http://packages.ubuntu.com/karmic/xserver-xorg-video-openchrome

[George Varghese (geovar)]

Ubuntu 9.04 did not go past the flickering screen during
installation. So I never installed 9.04. That is this bug i.e.
installation media of 9.04, downloaded from Ubuntu website does
not detect the display and ends up in a test pattern in NC20.

Now about 8.04: It installed just fine. It automatically detected
display and automatically installed openchrome that came with
the installation ISO image. Looked like the fonts were not very
smooth though. So I downloaded and installed openchrome from
trunk(latest version) and made changes to xorg.conf as suggested
by someone responding to this bug. It works ok except that when
the screen saver starts the screen goes black/dark and I am not
able to bring it back by pressing any key. I can see a shadow of
that window asking a password. Giving a password also did not
help. This could be another bug which I found yesterday after
installing latest openchrome. I am using this system now.

[Bartosz Kosiorek (gang65)]

The Samsung NC20 autodetection was added in Openchrome revision 737. In Jaunty there is only 713. The Samsung NC20 support is available only in Karmic release.

Please try do the following:
1. Upgrade xserver-xorg-video-openchrome from Karmic
  You can download it from:
  http://packages.ubuntu.com/karmic/xserver-xorg-video-openchrome

or

2. Build the latest (trunk) revision.

All was described at:
https://help.ubuntu.com/community/OpenChrome

To run Ubuntu Jaunty try to change to VESA:
Go to
     Section "Device"
and change/add
     Driver "vesa"

[George Varghese (geovar)]

Ok, so this is what I understand. I am new to the bug tracking
process in Ubuntu. Please bear with me if I sound quite
naive :-)

Jaunty has openchrome:713 in it and they may or may not upgrade
to 737 in Jaunty. The changes required to support NC20 is added
in 737 and later which will go into a future releases of Ubuntu
and may be Jaunty too. So, if I want to use openchrome with
Jaunty, in the meanwhile, I should follow the procedure
described in links you suggested which basically means getting
the a version of openchrome later than 737. Fair enough. I will
upgrade to Jaunty when I get some time. Thanks very much.

But for a new user, this is a hurdle to install Jaunty. The
installation program could use a default usable display
(driver "vesa") which may not be the best for NC20 (i.e.
openchrome 737 or later). Somehow this is done in Ubuntu 8.04
and the installation has no problem although the display is not
very good. That is fine. I believe that if no suitable display
driver is available, there should be a default scheme which
works in any case. This may not be implemented correctly in
Jaunty. Could you please correct this until a stable openchrome
goes into Jaunty.

 May be then this is not an openchrome issue, but an xorg or
installation script issue.

[George Varghese (geovar)]

As requested by Bartosz and our private correspondence I did the following. Quoting a mail to Bartosz.

" Thanks for your efforts. Please give me time till week end to try Jaunty. In the meanwhile this is my experience with Ubuntu 8.04 and openchrome latest trunk (last weeks.) I followed the instruction in https://help.ubuntu.com/community/OpenChrome and installed openchrome in NC20. It went well. I could see a better display - basically the fonts looked better on their edges. But  I am facing following problems after installing latest openchrome.

1) When screen saver starts up and after a while the screen becomes very dark. There is no way I could get usable brightness. Fortunately it is sufficiently bright to click shutdown and restart the machine if the ambient light permits.
2) When I play a movie with totem and click the menu items, they go behind the movie playing. So I can not select the menu items.
3) When I play a broken or incomplete movie totem freezes and keyboard does not respond. Not even CAPS key. I had to reboot. I tried to reproduce the problem. I then changed the xorg.conf and removed the entries for openchrome. After reboot the above problems are not seen anymore.

Please let me know if i should indeed install Jaunty to try this. If so, I will require a weeks time. Any other tests that I can do on 8.04 can be done immediately. Thanks very much for your contributions :-)"

Bartosz replied :
"Please attach Xorg.0.log and xorg.conf from Hardy and Openchrome trunk"

Please see my xorg.conf and xorg.0.log after I reverted the changes made to xorg.conf (deleted lines for openchrome)

[George Varghese (geovar)]

Last week I compiled and installed openchrome again. After this I get frequent Kmail crashes. I am not sure if this is a kmail problem or openchrome problem. I experience it when I try to delete some emails in Kmail. I am attaching the crash report if it helps.
Thanks.

[George Varghese (geovar)]

Just for record (may not be exactly this bug though). I tried
last weeks openchrome SVN trunk on Samsung NC20. Some videos
freezes the screen and computer. Is there anything I could help
with? Logs?

[Bartosz Kosiorek (gang65)]

Hello all.

@ Frank Bartels - could you please add new bug to lunchpad, with Xorg.log and xorg.conf file attached?
Please build/install the latest openchrome driver and enable debug mode.
The detail build instruction for Ubuntu/Debian is available at:
https://help.ubuntu.com/community/OpenChrome

@ George Varghese - What exactly problems do you have on the latest Openchrome revision? Attach your /var/log/Xorg.0.log file.
If you can from after reproducing this issue (or /var/log/Xorg.log.old).

[George Varghese (geovar)]

I could not reproduce it predictably. But just now I experienced
it. I was running OpenOffice to edit a document. Kmail and Firefox
were open during this time. The display froze and ctrl+alt+Fx did
not work. I tried F1 through F12. The caps key also did not work
(no LED). Then I had to reboot the laptop by switching off-on. I
am attaching the log files with this email. These files are taken
immediately after I rebooted the laptop. I did not find
Xorg.log.old Instead, the closest I found is Xorg.0.log.old which
is attached. The openchrome version is one week old.

[George Varghese (geovar)]

I could reproduce the problem. The crash occurred when I tried to
play a FLV video file using Totem Movie Player 2.26.1 using
GStreamer 0.10.22 which is the default player in Ubuntu. The
video file in question was

Type - Flash video (video/x-flv)
size - 47.2 MB (49491413 bytes)
Duration - 18 min 38 sec
Video
 Dimensions - 640x480
 Codec - On2 VP6 Video
 Framerate - 25 frames per second
Audio
 Channels - stereo
 Sample rate - 22050 Hz
 Bit rate - 32kbps

This video file plays in Totem, like other videos. But when it is
part of a play list and when it starts to play this file the
display and laptop freezes. No ctrl+alt+F works. No mouse
movement. No CAPs LED. I had to power cycle. After reboot the
WLAN does not come up (which is another issue). I am attaching
the log files before I started the experiment marked as
'beforeCrash' and after the power cycle marked 'afterCrash'.

[Bartosz Kosiorek (gang65)]

Attach your xorg.conf file.
Could you please give me a link to this FLV video?

Try to install VLC media player, and check if this error still exist.

On the latest openchrome svn revision, you have only problem with FLV video?

Have you got problem with screensaver?

[Tom Vijlbrief (tvijlbrief)]

Just tested booting the latest 9.10 beta distribution from USB-stick on my NC20 (which runs 9.04 quite good with a manual installed OpenChrome driver).

The system boots and even plays the desktop sound, but the screen shows neat test patterns in a sequence (solid red,green,blue,white,black and grey scales).

I cannot get access to a shell or login prompt with ctrl-alt-numberkey.

[Bartosz Kosiorek (gang65)]

Hi Tom.
Try run Ubuntu in safe mode (without X) and attach your /var/log/Xorg.0.log.old file (or Xorg.0.log.fail) to this bug.

Build/install the latest openchrome driver and enable debug mode.
The detail build instruction for Ubuntu/Debian is available at:
https://help.ubuntu.com/community/OpenChrome

[Tom Vijlbrief (tvijlbrief)]

Hi Bartosz,

Selecting SafeGraphics with F4 and double enter still starts X :-(
I'm feeling a bit stupid, but I cannot find the required boot prompt options to skip the X-server. Entering rescue
as option did not work either.

[Tom Vijlbrief (tvijlbrief)]

Single did the trick. I have also Xorg.0.log.old but I believe this one is the most useful.

Will try compiling as suggested tomorrow...

[Tom Vijlbrief (tvijlbrief)]

Just compiled and installed the latest svn version from openchrome and the system now boots just fine!

Let me now if you want me to perform some additional tests.

[George Varghese (geovar)]

I missed one important information. My comments from 2009-Oct-05
onward correspond to Ubuntu 9.04. I installed Janty(9.04) after
compiling and installing the latest Openchrome using live-
CD(Unetbooting). This is the workaround for the original
bug(installation problem).

I confirmed the results earlier with today's SVN trunk (811)
@Bartosz
a) I do not have the link to FLV file now. Sorry about that.
b) Yes, i do have problem with dark screen saver. But the mouse
pointer is visible on the dark screen. ctrl+alt+Fx gives terminal
window and log-in prompt. When I enter my login-name, it asks
password. But now the password is echoed (what I type as password
is shown back) on the screen and it does not login. Some error
messages keep scrolling after that which I do not remember now.
c) Abotu VLC player : I could install and play the videos in a
play list. But when I click full-screen the screen and laptop
freezes. I had to power cycle. Not tested in today's trunk.
d) Xorg.conf is attached with this email. All the logs you asked
for, earlier, are attached with this email. I enabled debug
information by ./autogen.sh --prefix=/usr --enable-debug --
enable-xv-debug
Please let me know if you need some more info.

We are tracking multiple problems in this bug. I summarise them
to test them in future. If you agree I will create separate bug
reports.
1) Test pattern during installation of Ubuntu 9.04
   (the original bug)
2) A while after screen saver starts, the screen
   becomes dark. Mouse pointer visible and moving.
3) Screen and computer freezes while playing certain videos
    in a totem play-list or VLC player in full screen.
4) External monitor not tested. (I just remembered this)

[Bartosz Kosiorek (gang65)]

Try to remove:
         Option "ActiveDevice" "LCD,CRT"
line from your xorg.conf file.

[Tom Vijlbrief (tvijlbrief)]

1 is fixed on my 9.10.
4 is ok, external monitor works.
3 looks good. Playing iso dvd images with mplayer and xv works fine in
fullscreen.

Note, 4 is with the

         Option "ActiveDevice" "LCD,CRT"

line. Should I retest without it?

[Tom Vijlbrief (tvijlbrief)]

Regarding the external monitor, the mouse cursor representation is scrambled...

I forgot to mention that

[George Varghese (geovar)]

I removed Option "ActiveDevice" "LCD,CRT" with version 811. I
did not get time to check 1&4 (installation problem and ext
monitor)
2) I do not see any problem with screen saver now. Looks fine.
3) Totem player and computer freezes while playing some playlist
even after removing the option.Do you need log files?

[George Varghese (geovar)]

I updated openchrome to version 815. Problem seen with screen
saver is fixed (811 did not do this). Still many video files
freezes screen and computer. It is not just FLV files. But many
others too. It is seen in VLC player and totem player. Further
while playing a file in totem player if the plus sign is clicked
to add more files to playlist, the window to select files appears
behind the movie being played. Any more logs required?

[Frank Bartels (fraenkiebartels)]

On Youtube.com you can see the Problem with the Installation Ubuntu 9.10 on Samsung nc20 :

http://www.youtube.com/watch?v=FLxCUYSBan0

I am using Ubuntu 9.04 with xserver-xorg-video-openchrome 1:0.2.903+svn741-1+b1
The System works very good and i am waiting for ubuntu 10.04

[Bartosz Kosiorek (gang65)]

To solve this problem, try to use VESA drier (or run recovery mode) and build/install openchrome from svn and enable debug mode.
The detail build instruction for Ubuntu/Debian is available at:
https://help.ubuntu.com/community/OpenChrome

[George Varghese (geovar)]

Bartosz,

Please see the log files before and after crash. It is built with
debug option. I do not have LCD, CRT option in xorg.conf file.

[George Varghese (geovar)]

Till now external monitor was not working. I updated the latest
to latest openchrome version on Samsung NC20 today. I also made
changes to xorg.conf as said in NC20 page.

https://help.ubuntu.com/community/NC20#Build%20from%20SVN
Mainly LCD/CRT line and DefaultDepth 16 line.
Here are my first observations. External monitor is working now.
That is a great thing and I am not limited to my small screen any
more. Thanks very much guys.

I am not sure of the crash/freeze. I will report it if I observe
it. But, when I play videos I can see it on laptop monitor. On
the external monitor I see a green box in place of video. If I
change to full screen mode, I see full green external monitor.
When I play a video from you tube I can see that on external
monitor. But when I change it to full screen there is a picture
in picture.

[George Varghese (geovar)]

New observation. During Ekiga echo test, I can view my webcam on
the netbook screen but not on the external monitor. There is a
black box just like in video play back. After some time, I guess
when I moved mouse over the video, the computer froze. I had to
hard reset. After this I see a distorted mouse pointer on the
external monitor. Mouse pointer on the netbook monitor is fine. On
the external monitor, mouse pointer is seen enclosed in a white
box of horizontal lines, about the size of a postal stamp. During
normal video playback(totem) also the netbook froze once. But
significantly less than it used to freeze before. Overall good
improvement.

This netbook is capable of higher resolution including full HD
1920x1200, 1920x1080, 1600×1200, 1280×1024, 1280×800, 1024×768,
800×600, and 640×480.
[http://www.geek.com/articles/gadgets/review-samsungs-nc20-
netbook-20090515/]. The maximum I see on display manager is
1280x800

[George Varghese (geovar)]

I tried to update the openchrome driver today to version 839. The make command gave some errors. And did not complete it. They were related to
via_drm.h -- expected specifier-qualifier-list before ‘__u32’
via_accel.c -- about some missing members.
The complete log is attached.

[George Varghese (geovar)]

I had a look at what is changed in latest via_drm.h (svn diff -r 838:839 ) In many places (or everywhere) uint32_t is replaced by __u32 which is not recognised. Google suggests including types.h befoe __u32 is used. But there are two types.h, one in asm and the other in sys. @Gang65 who did the latest checkin. Could you please check this? I might be able to try if someone could give some hints.

UBUNTU 10.04 BETA2 amd64 INSTALLATION FAILED WITH WHITE, BLACK, GREEN AND RED SCREEN!!
it's unbelievable....

[Andreas Waigel (crazy-peanut)]

Same Problem with the10.04/i386 Version. I have the display test pattern screen AFTER the Setup instead of GDM on my NC20 (Setup is running properly). GDM is running properly, no errors reported in Xorg.0.log, so driver says "everything ok". Setting the system to Stand By mode within the test pattern screen, an waking it up again solves the Problem until the next start of GDM.
I had the same Problem with Ubuntu 9.10. Installing the openchrome 0.2.904~svn814 release solved the problem for Ubuntu 9.10. It seems that the new svn827 brings this bug back into the release.

[Frank Bartels (fraenkiebartels)]

Using live-cd works and the desktop loads ....everything works fine in live-modus.
Installation works fine , but after restart we have pattern on screen.
I cannot go to the console or everything. the system hangs of.
I am very frustatimg frustrating.

working with VX800:

svn741-1.deb
svn814-1.deb
nothing else.

[Frank Bartels (fraenkiebartels)]

Hello!

I have found there is a difference about the driver Date!!!!!
Ubuntu xserver-xorg-video svn827-1 from 22.March 2010
Debian xserver-xorg-video svn827-1 from 12.Jan 2010

Next i will testing the Debian driver and will see how it works.
I hope it will......

[Andreas Waigel (crazy-peanut)]

The latest update to kernel 2.6.32-20 and/or X.Org X Server 1.7.6
Release Date: 2010-03-17 seems to solve the problem. Switching to console corrupts the screen. Switching back to the graphical system is possible.

[Frank Bartels (fraenkiebartels)]

Thanks Andreas for the Info!!
Corrupts with console is fixed in later openchrome versions.
I mean svn840 or svn841.

[Bartosz Kosiorek (gang65)]

Hello.
The problem with suspend and VT switch on VX800 chipset and 64bit systems was solved in svn838.

yesterday. It works fine with respect to booting. No test pattern
seen while booting. But when we shut down there is a test pattern
on screen. It does not affect normal working though. We just miss
the beautiful Ubuntu logo to a test pattern while shutting down.
A similar test pattern, though not exactly same, flashes the
window when I try to open an email in kmail by double clicking.

Try to apply this patch.
Try also switch to EXA and check if this problem still exists

> Try to apply this patch.

In my Lucid installed NC20 I applied the patch. I see the same
test pattern when I open emails in kmail. I also see test pattern
when I press ctrl+Alt+Fx. Those terminals are not usable.
Everytime I press, say ctrl+alt+F6, I see a different test
pattern. The main characteristic is horizontal lines with
different background colours. The lines also look different every
time I press ctrl+alt+Fx. I get back original screen when I press
ctrl+alt+F7

Could you tell me what/how to switch to EXA? If it is external
monitor, clone mode works with the patch you sent. But
ctrl+alt+Fx turns external monitor to blank screen.

[Bartosz Kosiorek (gang65)]

To switch to EXA you must create/edit /etc/X11/xorg.conf file, and add/edit section "Device", as follows:

Section "Device"
 Option "AccelMethod" "EXA"
EndSection

[George Varghese (geovar)]

> Option "AccelMethod" "EXA"
I tried this option with latest openchrome from SVN trunk on
Lucid Linx beta 2. The test pattern exists when I press
ctrl+alt+Fx. With and without EXA. I can send a picture of the
same if needed. I also had experienced a freezeup when I played a
video in totem player yesterday. VLC player is stable though. I
am novice programmer too. Bit lost looking at the openchrome
source code. If you could suggest where I could start looking, it
would be very helpful.

[Bartosz Kosiorek (gang65)]

The problem with EXA and XV was solved in changeset 840:
http://www.openchrome.org/trac/changeset/840/trunk

Attach your Xorg.0.log file before and after press
ctrl+alt+Fx

[Bartosz Kosiorek (gang65)]

Attach also your Xorg.0.log file after XV freeze

[George Varghese (geovar)]

Please see attached. These are taken just before and after
pressing ctrl+alt+Fx. I will get you the log when the freezeup
happens again.

The problem with the green flash and blank console is caused by one of the framebuffer video drivers, vga16fb. Ubuntu seems to load it by default on boot, so you must tell Ubuntu not to use it. You need to change a configuration file by hand for this and you need root privileges.
1. Boot your Ubuntu or some rescue CD/DVD or whatnot, you'll need to access (mount) your installation partition.
2. Open /etc/modprobe.d/blacklist-framebuffer.conf on your installed Ubuntu in a text editor
3. Add a new line:
Code:

blacklist vga16fb

OPTIONAL: Comment out (add a # at beginning) the line
Code:

blacklist viafb

4. Save the file and exit the editor.
5. Reboot
Chances are that the normal text console will work now, but maybe you'll lose the boot splash screen...

tom09.

Works!

I used only: blacklist vga16fb

[Frank Bartels (fraenkiebartels)]

Works!!!

[George Varghese (geovar)]

Yes, it works. Thanks very much Mark.
But why did it happen in the first place. It was working before.
After the last kernel update something went wrong which might
need fixing? Since I have that partition still available, I can
upload any logs required. Please let me know.

[Roberto Innocenti (robyinno)]

With my Wibrain from Ubuntu 9.10, and from Mandriva 2010.0 and Fedora 13 the LCD 4.8 inch of Wibrain heavly flicker,
with an external LCD Monitor no problem.
I have even fixed the DSDT ACPI and add with Ubunytu 10.4 kernel.
With the legacy option in xorg.conf with the svn trunk of Openchrome driver not became the screen white instead flicker and going in tho console mode CTRL+ALT+F1...F5 instead of White become black the screen.

I have tried with different xorg configuration with the result that some time even the External LCD doesn't work.
I have tried even VESA driver but dosen't find the right video modes...
I have tried installing the propritary VIA driver but they was installable on Ubuntu 9.04 but not on 10.04, I have tried to compile from source but they are not compilable for the dipendense from some .h that with the new xorg-dev are not existent.

I have started live cd of OpenSuse 11.3 and start correctly with vesa.
I have tried xvidtune and changed some parameter , switching off my exernal lcd and hand the flickering change in relation to the changes, but remain flickered....

[Roberto Innocenti (robyinno)]

I have tried even with the ppa 2.6.35rc6 kernel but the problem is the same.

[Roberto Innocenti (robyinno)]

I have tried even with the kernel option apci=copy_dsdt that force the kernel to read the buggy dsdt in the buggy Windows way, but the problem still remain, just flicker strong. This doesn't happen until Ubunt 9.04 .

[Charlie Kravetz (cjkgeek)]

Roberto Innocenti:
Could you please file a new bug by opeing the Terminal and typing

ubuntu-bug xserver-xorg-video-openchrome

You can enter in the description that it is related to bug 374090.
Thanks.

[Roberto Innocenti (robyinno)]

I have solved the problem doing like this:
after have installed Ubuntu 10.04 with external monitor i have installed:
    sudo apt-get install v86d

    gksu gedit /etc/default/grub

change the line:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

with:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1024x600-24,mtrr=3,scroll=ywrap"

substitute the line:

    #GRUB_GFXMODE=640x480

with:

    GRUB_GFXMODE=1024x600

-----------
    gksu gedit /etc/initramfs-tools/modules

add ad the end of the file the following line:

    uvesafb mode_option=1280x1024-24 mtrr=3 scroll=ywrap

then do:
    echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash

    sudo update-grub2

    sudo update-initramfs -u

then for see the cursor do what is suggested on:
http://samiux.wordpress.com/2009/05/15/howto-via-s3-unichrome-pro-problems-fixed-on-ubuntu-9-04/

    sudo nano /etc/X11/xorg.conf

Add the following lines to the Section Device.

    Option "PanelSize" "1024x600"
    Option "sw_cursor"

The final looking on the Section is :

    Section "Device"
    Identifier "Configured Video Device"
    Option "PanelSize" "1024x600"
    Option "sw_cursor"
    EndSection

Hi,

It is more than 2 years since I reported this problem. In between, i upgraded my Ubuntu to Natty where this problem is not seen. Therefore, I can not test this bug any more. I have added the files you requested with Natty. This is only to help you, if it does in someway, in future development.

george

[Brad Figg (brad-figg)]

This bug seems to have been fixed since at least Natty.

[Alberto Jovito (thedemon007)]

Maybe this was caused by a kernel configuration error.

It happened to me with archlinux, the ttys in blank and openchrome crash, I'm testing but after today's update the ttys (ctrl + alt +1.2 etc) are displayed correctly.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Alberto Jovito (thedemon007)]

I have same problem after update to trusty 14.04 no can see ttys (ctrl + alt +1.2 etc).

We can now install Ubuntu 16.04 on samsung NC20 without problem. (Thanks lepetit)
