Red Hat Bugzilla – Bug 6958
System freeze under KDE/GNOME/Window Managers
Last modified: 2008-05-01 11:37:52 EDT
Description of Problem:
If any KDE or Gnome application is run, or anything on the AnotherLevel
bar is used, the system will freeze within 3 minutes.
The mouse cursor dissapears and I cannot type anything. I cannot toggle
numlock or reboot using CTRL-ALT-DEL.
Problem does not affect:
Non-X Linux, Normal X, AnotherLevel menus(maybe), "failsafe" mode from
an X display manager, MS-Windows programs (under MS-Windows).
I installed RedHat 6.1 and was gradually shrinking the size of my
windows partition, in a premeditated move to delete it and run only Linux.
Everything worked fine at this point. Then I uninstalled GNOME in order to
move to KDE. I did this by using rpm to remove every gnome package on my
system. I then bought a Paradise External Modem because my AOpen PCI modem
didn't work, and decided to buy a Cirrus Logic 5465 PCI video card to
replace my old, snow-bound Cirrus Logic 5446 PCI video card.
When I installed the new hardware, I decided to reinstall GNOME, by using
rpm on all the GNOME packages. No errors here.
I noticed that everything worked better except with this new hardware
except that if I ran any KDE or GNOME application, including only kvt or
the Gnome terminal, the system would crash within a few minutes. The
problem and may not exist if I only run AnotherLevel or regular
X, since I have not experienced the problem running either of those two
configurations. Of course, the problem does not ever occurr using the
POSSIBLE CAUSE: Bad X drivers? Problems with KDE and/or GNOME?
I doubt it is actually a problem with KDE or GNOME, because both desktop
environments seem to cause this problem. So I strongly suspect it is a
configuration error or a problem with the X drivers for the CL-5465
chipset. However if you know ANY WAY I *MIGHT* be able to fix this
problem, then please tell me! I'd do anything to run KDE. You see, I am
trying to impress my boss into using Linux + StarOffice/KOffice at work (5
computers) instead of MS-Windows + Office, and this is the critical
juncture. I need it to work for at least 20 minutes in a row.. Please
RedHat 6.1 (Cartman) distribution kernel 2.2.10.

Dear Sir; I have resolved this problem. It is a buggy X driver! In order to use
these cards, please use a colour depth of 16 bits at 1024x768 (or whatever). The
reason they crash is because the C drivers don't like the 32 bit colour depth I
was using. 24 bit depth is yet untested but hey, who cares, i'm in 1024x768 mode
and it RUNS GREAT! :)
Oops, make that X drivers. Even thought they *were* probably written in C... hee
this will be fixed for the next release.
