Bug Description

Binary package hint: xserver-xorg-video-intel

Hi,

I am using mythbuntu, and updated the system from 8.10 -> 9.04. Everything works (more or less) fine, but I still have a problem with the graphics. If I want to shutdown/reboot, all programms terminate, the screen gets black, but the system does not shutdown/reboot, and the system is not longer reacting (console, ssh, ping). It´s a classical freeze.

The same happens if I want to restart the X-server by sudo /etc/init.d/gdm restart.

After reeding the release notes of 9.04, there are some hints about problems with intel graphics. So I added 'Option "DRM" "OFF"' to xorg.conf, and the problem was gone.

The switched off DRM option has no real pain for me, because I use the computer only as a mythtv backend and fronted, so high performance graphics are not so importand.

[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.

Hi,

I tested Karmic (alpha 2), and it has a kernel panic after the grub bootloader. I'm sorry, but I found no useable way to get some useful information.

But:
So I updated my 9.04 to kernel 2.6.30 and also the xserver-xorg-video-intel to
2:2.7.99.901+git20090701.1e4784bf-0ubuntu0sarvatt~jaunty
and everything is working well (including KernelModesetting). I used the way descriped in:
https://wiki.ubuntu.com/X/KernelModeSetting
Also the DVI-output works now fine.

I think this topic can be closed. I think the kernel panic in Karmic alpha 2 has nothing to do with the intel driver, and 9.04 is working very well now with the updated kernel and video-driver.

Thanks a lot

Robert
