[i855] LVDS/TFT output fine VGA output not displayable

[joerg jungermann]

Binary package hint: xserver-xorg-video-intel

Hi,
I own a Toshiba Satelite SA50-532. It is equipped with an Intel GME855 graphics chipset (lspci below)

I have trouble activating VGA output, if VGA monitor is not connected at bootup. There is no difference if X is started with the monitor connected or not connected.

If monitor is attached i can do
# xrandr --output VGA --mode 1024x768 --rate 75 --same-as LVDS
or
# xrandr --output VGA --mode 1024x768 --rate 75 --left-of LVDS
 If the monitor was present at bootup, the above lines work as documented.
The first line clones the screen. The second line extends the screen.

If the monitor was not connected while starting the system. TFT monitors are not able to sync the signal, even my Sony Syncmaster Multiscan 500PS 19" has problems: Sometimes it successfully gets sync. Then it shows a very flickering screen with somehow shifted colours. It tells me in its status menu, that it has not 75Hz as expected, but with vertical refresh like 58.68Hz or 57.59Hz. I don't know if these colors are meassured correctly by the monitor.

The xrandr output makes no diffence if monitor is absent while starting or if it is present.
The following output are from xrandr command with monitor plugged or not plugged in, while in X.

# xrandr # VGA absent

I removed the config file /etc/X11/xorg.conf and started the X server in absence of this file.
I now uses its builtins. The behavior is the same.

Hi joju-math,

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

[joerg jungermann (joju-math)]

Hi !

The information you automatically asked for is already in the previous comments to this bug.

Possibly it is related to the debian bug:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=476575

Because the Toshiba S50 and S55 have the same mainboard.

cya

[Bryce Harrington (bryce)]

Okay thanks. (The script was just unable to tell the info is there if it's pasted in rather than attached.)

[Geir Ove Myhr (gomyhr)]

joerg, it is easier to browse the bug when the long logs are in
separate files. I attach them here, and I will delete the
corresponding information in the description.

[Bryce Harrington (bryce)]

Well, next I'd like to forward this issue upstream, but first it must be retested on latest development version of Karmic to make sure the issue still happens there with the latest code. ISO images are available at http://cdimages.ubuntu.com/releases/karmic/. If you can reproduce it in the LiveCD environment, you shouldn't need to modify your installed system. Also please attach a fresh Xorg.0.log and dmesg from this testing.

[Geir Ove Myhr (gomyhr)]

This bug report has been inactive for quite some time and in the meantime Ubuntu has moved along. I hope the reported problem has been resolved in the current version of Ubuntu. If it has not and there are people willing to follow up with information collecting and testing, it is best to file a new bug report with the latest Ubuntu development version (10.04 still works, but soon 10.10 is better), using the ubuntu-bug command if possible. Feel free to mention the bug number of this bug.

We are sorry that we are not always have the capacity to look at all reported bugs in a timely manner. Occasionally we have to purge old bug reports where no progress has been made, whether it is due to reporter not being able to respond or lack of manpower on the Ubuntu side, in order to keep our list of "active" bugs current. Sorry for the inconvenience this may cause.

Here are a few tips that will make it easier for triagers and developers to process your bug:
* Read https://wiki.ubuntu.com/X/Reporting
* Browse https://wiki.ubuntu.com/X and see if there is some relevant information for you problem
* Respond quickly to questions from triagers
* Try changing things to see if the behaviour changes, e.g.
  * A new mainline kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D (more information at https://wiki.ubuntu.com/KernelTeam/MainlineBuilds)
  * The xorg-edgers PPA: https://launchpad.net/~xorg-edgers/+archive/ppa
  * Various options in `/etc/X11/xorg.conf` (see `man intel`)
* Browse other bug reports to see if you find a similar one and provide the information that is being asked for there.
