Description Will Woods 2008-03-10 18:34:36 UTC 
On my rawhide machine, xorg segfaults when you click on the "Other.." user item
in GDM. 

xorg-x11-server-Xorg-1.4.99.901-1.20080307.fc9.x86_64

gdm-2.21.9-0.2008.03.10.1.fc9.x86_64

Here's the backtrace:

Doh. Too much time with python tracebacks or something; read this one backwards.
It's probably an evdev bug. 

xorg-x11-drv-evdev-1.99.1-0.1.fc9.x86_64
Comment 3 Adam Jackson 2008-03-11 23:30:12 UTC 
Unable to repro this here.  That backtrace is _really_ weird, the sis driver
normally doesn't set modes with VBE.

Not sure this is strong enough for a beta blocker.
Comment 4 Will Woods 2008-03-12 00:21:37 UTC 
Whatever it was, it's stopped happening now. Closing RAWHIDE; if it comes back I'll reopen.
