[i865] Crash on logout with KDM
https://bugs.launchpad.net/bugs/628077
The changelog of xserver-xorg-video-intel (2:2.12.0-1ubuntu5) quoted in that
bugreport contains:
* debian/patches/101_copy-fb.patch: Move scratch pixmap creation to the
drmmode_copy_fb function, and clean up after we've used it. Fixes the
SIGSEGV in FreeClientResources when logging out of KDE (LP: #628077)
Other possibly related reports:
[i945g] The computer logged me out without my permission.

Here are further hints:
X crash on KDM logout (still - yes, really)
https://bugs.launchpad.net/bugs/651294
"On some Kubuntu systems, the display server crashes on logout instead of
returning to the KDE Display Manger (KDM) login display. For systems with this
problem, the problem can be avoided by changing the method KDM uses to
interact with the display server. Edit /etc/kde4/kdm/kdmrc and uncomment the
line "#TerminateServer=true" by changing it to "TerminateServer=true" and
restart KDM (reboot the system or sudo restart kdm)."
I test this: This actually works around the problem on the FTS workstation
with Intel KMS and on the ThinkPad T42 with Radeon KMS.
I didn't see this with X.org packages from Squeeze.
On the FTS workstation I currently use:

I am using libdrm 2.4.21 here, since with 2.4.23 there X.org server locks up
hard quite often. I had lockups with 2.4.21 as well, but not as often.
Hardware there is:
