[Karmic] X crash due to xsetroot in startkde after recent update
This report is based on a bug hunt I did on a system maintained by ~ericbouer.
Apparently the system was setup about a week ago and after some recent update, login was never successful and always resulted in an immediate bounce back to KDM.
After a lot of investigation it became apparent that
xsetroot -cursor_name left_ptr
as part of the startkde script was causing a X crash. However, the command itself could not be used to reproduce the crash, it seems as if only the preceding commands in startkde make it a deadly one. Removing aforementioned line prevents the crash, re-adding it makes the crash again 100% reproducible.
Reinstalling x11-xserver-utils, which contains xsetroot, did also not improve the situation. Only removing xsetroot from startkde makes logins possible again.
Attached to this report you find:
* gdb-Xorg.txt - backtrace per https:/
* .xsession-errors of two different users, in one the xprop commands in startkde were commented out (which turned out to not improve the situation)
* Xorg.0.log, Xorg.0.log.old, kdm.log, dpkg.log
* Output of dmesg and lspci -vvk
