Comment 0 for bug 383345

1) This is a bug reported from Ubuntu Karmic Alpha:
https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/383345

2) System environment:
-- chipset: 945GM
-- system architecture: i686
-- xf86-video-intel version: 2.7.99.1+git20090602.ec2fde7c with Ubuntu patches, and also git b8e360bf2b77d28559d15a7c0f9c766848eb6ced
-- libdrm: 2.4.11
-- kernel version: 2.6.30-7-generic
-- Linux distribution: Ubuntu (Karmic Alpha)
-- Machine or mobo model: Dell Latitude D820
-- Display connector: VGA

3) Reproduce steps:
Have a setup with two screens and working virtual resolution (for me: Virtual 2960 1050).

On Ubuntu Karmic upgrade xserver-xorg-video-intel to 2:2.7.99.1+git20090602.ec2fde7c.

Reboot and notice that when gdm starts the screen gets black, you have a working mouse, but there is nothing to click on: the taskbar and the menu bar are not loaded, no icons, nothing. Reproductibility 100%.

Remove virtual resolution from xorg.conf, restart gdm and notice that the menu and task bars appear and that you have mirrored monitors (same image on both). Changing resolutions (same resolution for both monitors or different resolutions - does not matter) and having different displays on each monitor works IFF the resolution combination does not need virtual resolution setup in xorg.conf.

I built a .deb package out of git b8e360bf2b77d28559d15a7c0f9c766848eb6ced (current HEAD) and installed and experienced the same problems. (The .deb package can be found at https://edge.launchpad.net/~lucian.grijincu/+archive/xserver-xorg-video-intel).

I can confirm that with the previous Ubuntu package xserver-xorg-video-intel=2:2.7.1-1ubuntu1 everything worked fine. You can get that package from http://archive.ubuntu.com/ubuntu/pool/main/x/xserver-xorg-video-intel/ - it contains some patches over git tag 2.7.1.
