[fb MMX] X crashes after login
Last modified: 2018-04-11 10:17:38 EDT
Description of problem:
X crashes after login as user. I have this happening on two computers with
different graphic cards, both are AMD though. I think it might be related to a
transparent gnome-panel. It works when i switch to a text console during login
and then switch to x11.
Version-Release number of selected component (if applicable):
fc5 with updates
login on my machine, but it does work sometimes.
Steps to Reproduce:
here is an excerpt of my Xorg log:

Fatal server error:
Caught signal 11. Server aborting
Seems to be a common problem being reported. This is the 3rd or 4th bug report
I've seen with a backtrace pointing at the fb MMX code causing a SEGV.
I have switched off the transparency of gnome-panel on one machine and the
problem went away there.

Please attach your X server log and config file, from a session in which
you experience this problem, as that will help diagnosis.
This seems to work now. I can't remember which update fixed it.
