Description Leonid Podolny 2010-09-10 09:10:58 UTC

With new KDE 4.5.1 and 2.6.35-gentoo-r5, when changing the screen resolution, I get the following kernel OOPS:

Comment 1 Leonid Podolny 2010-09-10 09:13:32 UTC

I sort of already solved it (by either using 2.6.36-rc3-00334-gdf423dc or patching 2.6.35-gentoo-r5 with this patch: http://www.mail-archive.com/intel-gfx@lists.freedesktop.org/msg00835.html)

Comment 2 Leonid Podolny 2010-09-10 09:18:16 UTC

Proper problem description:

HW:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

Two displays: LVDS1 with 1280x800 and DVI1 with 1680x1050.

Scenario:
- KDE starts with resolution of 1280x800
- I start krandrtray to change the resolution to match the bigger display.
- Change DVI1 to be 1680x1050, press Apply
- The screen freezes and I need to press the power button to restart the machine

Thanks for identifying the patch. 

Backported to 2.6.35 from kernel dev tree and will be in the next gentoo-sources-2.6.35-rX release.

Released in latest gentoo-sources release
