[PM800] Panel on PM800 is not supported.

[Vladimír Nováček]

Description: Ubuntu jaunty (development branch)
Release: 9.04

Screen resolution badly detected on FujitsuSiemens Amilo Pro V2010

Since 8.10 Ubuntu doesn't recognize resolution of the LCD. Correct resolution is 1024x768, but Ubuntu sets it by default to 1600x1200 which causes that large part of screen is not visible. Especially logging in is much more difficult.

Description of problem:
On GDM screen and in GNOME laptop has wrong resolution detected (see the

Preferences / Hardware / Screen Resolution" then in Gnome after login I see the
correct resolution but still on each GDM I see that the correct resolution is
not detected (look at the attachement).

[Xavier (xavier-redhat-bugs)]

Rather than a screenshot, I'd like to have the xorg conf and xorg log, please.
This can probably be worked around by setting the correct resolution in the xorg
conf.

As a workaround, in the Display SubSection of your xorg.conf, add the following
line :
Modes "1024x768"

I'm afraid there's not much that can be done for this bug until some development
around the panel code happen upstream.

[Valent (valent-redhat-bugs)]

Sorry for my ignorance, but what do you mean by "upstream panel code"? Do you
mean that I should report this bug to upstream unichrome project? X11? Or
something else.

Cheers,
Valent.

[Xavier (xavier-redhat-bugs)]

Sorry for not being clear. Upstream is currently working on improving the panel
code. This code is not completely stable yet, but I hope it will be in the
coming weeks. I'm following openchrome development very closely and the new code
will be in Rawhide soon after it is in openchrome subversion repository.
Actually, there is already a pre-version of this code in Rawhide, but I can't
promise it'll work. For the time being, the only possible solution to your
problem is probably to work around it.
One other possible workaround could be to use Option "PanelSize" "1024x768" in
the Device section of xorg.conf, with or without Modes "1024x768" in the
Display SubSection.

[Valent (valent-redhat-bugs)]

Oh, thank you.

I can live with this bug and if you need I can test the new openchorome driver
code if it will be pushed into Fedora 9 testing-updates repo. Just tell me if
you would find my feedback helpful or if you got everything under control :)

[Xavier (xavier-redhat-bugs)]

Valent, can you please give the latest rawhide package a try ?
xorg-x11-drv-openchrome-0.2.902-8.fc10

[Valent (valent-redhat-bugs)]

ok, I'll try it...

[Valent (valent-redhat-bugs)]

It is still the same. I'll upload Xorg.0.log a bit later.

[Valent (valent-redhat-bugs)]

I tested xorg-x11-drv-openchrome-0.2.902-10.fc10.i386 and I still see the same issue.

I tested this laptop with Fedora 10 beta and still no change, the screen is set to much higher resolution than it really is and I have problems even login on because I see only 1/4 of the screen :(

[Xavier (xavier-redhat-bugs)]

Unfortunately, the new upstream panel code doesn't support the CN400 chipset, it's aimed at K8M890, P4M900 and CX700. I had a try at enabling the panel code for CN400, VM800 and P4M890, but the test wasn't fully successful on a VM800, so I reverted the change. You'll have to live with the old modesetting method (VBE) for now, sorry about that.

[Steve Beattie (sbeattie)]

Thanks for taking the time to report your problem and help improve Ubuntu. Unfortunately, you haven't provided enough information for developers to determine why your screen resolution is getting misdetected. Can you please run the command 'apport-collect -p xorg 353208' which will collect diagnostic information related to X on your system and attach it to this bug report.

Please build, install the latest openchrome version according to:

apply patch:

panel_pm800.patch

and check if its helps.

Attach your Xorg.log

[Vladimír Nováček (qaculda)]

I tried to build openchrome with your patch, but I can't conform if it works, because on my screen was just grey fog(but computer reacted normally). I've had to reinstall xserver-xorg-video-openchrome package from repository.

Editing of /etc/X11/xorg.cong(the Display subsection) worked.

[Bartosz Kosiorek (gang65)]

Please attach Xorg.0.log from openchrome with applyied patch.

Try use CTRL+ALT+F1, or just attach Xorg.log.old after reboot.

This information will be useful in adding panel support for your chipset.

[Bartosz Kosiorek (gang65)]

Hi.
Please apply this patch to the latest openchrome driver.

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

[Martin (martin-redhat-bugs)]

I found this problem still exists in Fedora 11.
I had to install using text mode and a just my xorg.conf file manually.

[Vladimír Nováček (qaculda)]

It looks good now. Even the resolution is correct(without the Display SubSection in xorg.conf).

[Bartosz Kosiorek (gang65)]

Hi qaculda.
Please attach your xorg.conf file.

[Vladimír Nováček (qaculda)]

Sorry, my mistake.

Video is not working now, only black screen shows.

[Bartosz Kosiorek (gang65)]

So the X runs correclty, only playing movies is not working?

[Vladimír Nováček (qaculda)]

Yes, X runs correctly, but when playing a movie, only sound can be heard. The thumbnail is created normally, the size of the vlc XVideo Output window is OK(I've tried it on vlc and totem), only the picture is not visible. The output to terminal of Totem is identical with the output with the driver from repository(only one deprecation warning).

[Bartosz Kosiorek (gang65)]

Please enable debug mode, and rebuild openchrome:
https://help.ubuntu.com/community/OpenChrome#Problems%20and%20solutions

Then run VLC/Totem and attach Xorg.0.log files.

Try to change the Video Output to for example "xvideo" (xv) or "x11"

[Vladimír Nováček (qaculda)]

In VLC xvideo doesn't work(no change), x11 does.

[Yannis Tsop (ogiannhs)]

I have a PM800 based card and although I have tried everything so far there seems to be bo solution yet. I submit my xorg.log. My screen has resolution 1920x1080 (if this is too high I can try with another monitor).

@Yannis T
What kind of problem do you have?
Please apply the panel_pm800_3.patch patch according to
https://help.ubuntu.com/community/OpenChrome
and attach Xorg.0.log file.

[Vladimír Nováček (qaculda)]

No. Still the same.

[Yannis Tsop (ogiannhs)]

With openchrome/trunk (up to 751) when I boot my computer the kernel splash screen is misplaced to the bottom right (it looks like that if I had a bigger monitor it would be centered). Then when X starts the kdm login screen is also misplaced (the same way).

When I apply any of these patches the splash is again misplaced, but this time X does not start at all (the monitor enters energy save mode).

I remind you that my current monitor is capable of 1920x1080.

[Bartosz Kosiorek (gang65)]

@Yannis.
Please remove Option "PanelSize" "1920x1080" from your xorg.conf file and attach Xorg.log and xorg.conf.

To resolve this bug I will create the patch, which you must apply and check if its working.

[Yannis Tsop (ogiannhs)]

Waiting for your patch :)

[Yannis Tsop (ogiannhs)]

Bump!

[Bug (bug-redhat-bugs)]

Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

[Yannis Tsop (ogiannhs)]

Why is that??

[Yannis Tsop (ogiannhs)]

With this configuration works great.

[Yannis Tsop (ogiannhs)]

I added a line in Section "Device" that solves a bug with artifacts:

Section "Device"
        Identifier "Card0"

I added :
        Option "EnableAGPDMA" "0"

[Bartosz Kosiorek (gang65)]

Hi.
Please check if this patch is working for you.
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

Please attach your /var/log/Xorg.0.log file (or /var/log/Xorg.log.old).

[Vladimír Nováček (qaculda)]

Hi.
I've tried your patch. Screen resolution is still incorrect. Video with X11 is working, picture with XVideo is always on top and in vlc is green.

[Bartosz Kosiorek (gang65)]

Check is this patch works for you.
Try to enable/disable UseLegacyModeSwitch in via_driver.c

[Bartosz Kosiorek (gang65)]

This bug should be resolved in the latest openchrome revision.
Please build/install the latest openchrome driver and enable debug mode.

[Yannis Tsop (ogiannhs)]

With the latest driver from trunk it does not work. I will also try the patches you sent.

[Bartosz Kosiorek (gang65)]

So with latest driver the X even not starting?

If yes try check, in which revision this apear.

You can go back to the previous revisions by typing:
   svn update -r713

[Bartosz Kosiorek (gang65)]

Try also use option:
Option "ActiveDevice" "LCD"

[Yannis Tsop (ogiannhs)]

If I use the xorg.conf: http://launchpadlibrarian.net/29184878/fujitsu-openchrome-xorg.conf with

Section "Device"
        Identifier "Card0"

I added :
        Option "EnableAGPDMA" "0"

Everything works fine.

Without any xorg.conf the resolution is not detected correctly so most of the desktop is out of the screen with out any other distortion or problems.

[Bartosz Kosiorek (gang65)]

Check this patch on latest openchrome.

Is video is working correctly?

[Bartosz Kosiorek (gang65)]

Check if this patch works for you

[Martin (martin-redhat-bugs)]

Now that F12 is branched, I'll start to add more patches to the devel branch once openchrome 0.2.904 is out (should be real soon now).

[Yannis Tsop (ogiannhs)]

Without xorg.conf nothing works. I tried setstartingaddress2.patch with rev 793 and 811. Here are the logs.

[Yannis Tsop (ogiannhs)]

rev 811 log

[Yannis Tsop (ogiannhs)]

I just realised that even with the xorg.conf only resolution 1024x768 seems to work ok, anything else is miscalculated and there is workspace beyond the the edges of the monitor.

[Matěj (matj-redhat-bugs)]

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue.
