Bug Description

Binary package hint: xserver-xorg-video-intel

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu.
Description: Ubuntu 9.04 (Release Candidate upgraded from Ubuntu 8.10)
Release: 9.04

2) The version of the package you are using, via 'apt-cache policy packagename' or by checking in Synaptic.
xserver-xorg-video-intel 2:2.6.3-0ubuntu9

3) What you expected to happen
After attached the S-Video cable to my laptop, configured the position of the 2 properly detected monitors in gnome-display-properties, updated automatically the xorg.conf with the respective virtual resolution and , finally, logout and login, I expected to have an expanded dual monitor desktop with my laptop and TV (to see fancy films with my laptop in the TV :P).

4) What happened instead
First,
I did every thing what I described in point 3, and all I got was a white screen in the TV and in the laptop. If I made alt-tab I also got some little icons, but every thing around was white.

Secondly,
I manually edited xorg.conf, erased the virtualscreen resolution and booted again without the TV attached. I disabled all the desktop effects and tried every thing again, and, more or less, it worked. The bigest problem is that I can't open any film with this configuration, any video application crash silently when trying to play a film.

Hi pixolex,

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.

s-video cable pluged before boot, after login I disabled all desktop effects (compiz) and with the two screens (laptop at left and TV at right) well configured I tried to play flv a wmv films, that crashed silently.

I'm available if you want more info.

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:

  http://cdimages.ubuntu.com/releases/karmic/

If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as
well.

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.

I've tested the Karmic Alpha 2 Live CD and the white problem is now a black problem. After the S-Video cable attached to my laptop, configured the position of the 2 properly detected monitors in gnome-display-properties, updated automatically the xorg.conf with the respective virtual resolution and , finally, logout and login, the two displays (laptop and TV) were black. It's just possible to see the mouse arrow moving and a thin (1 pixel wide) line of the desktop in the left side of the laptop screen, all the rest of the desktop (laptop and TV) was black.

If the option is "mirror" it works, the laptop changes to 1024x768, like the TV, and it seems the 3D effects are working. I couldn't test the video because there are no VLC in the repos.

Thanks for testing, can you please attach an Xorg.0.log from this failure case? black/blank screen issues tend to be more fundamental than white screen issues (they indicate failure to establish a video mode, whereas white usually indicates a compositing-related fault).

Desktop box with Intel D945GCLF2 exhibits similar behaviour: with mirror on everything works, mirror off works if either output is disabled but with both enabled both screens remain black except for mouse pointer. Xorg.0.log attached.

More with D945GCLF2: The default resolution chosen by the driver was 1152x864.
Other resolutions work with mirror setup as well, but trying to turn mirror off with 1024x768 exhibited slightly different behaviour: the screens went blank for a moment, then returned (mirrored) with error:

"Could not apply the selected configuration
Did not receive reply. Possible causes..."

Xorg.0.log is rather big after that, but I'll attach it anyway.
And here's xrandr output (the monitor connected to VGA is actually 1280x1024):

More experiments: non-mirrored setup works if combined resolution is small enough that it works with default xorg.conf (without Virtual entry). E.g., 1152x864 on VGA and 800x600 on TVout works fine. Xorg.0.log reflecting this situation attached.

I've found the problem, it's like Gordon Jin (upstream) said, the problem it's with the virtual resolution when it's equal or higher than 2048.

I've tested every thing again in jaunty and Karmic alpha 2, but this time with a sum of resolutions shorter than 2048 (1024x768 + 800x600; 800x600 + 800x600; 1024x768 + 640x480) and I could play films and use the 3D effects of compiz.

So, this bug is, more or less, a collateral effect of this bug https://bugs.freedesktop.org/show_bug.cgi?id=21190
