Red Hat Bugzilla – Bug 242821
display corrupted when switching to graphical mode
Last modified: 2007-11-30 17:12:06 EST
Description of problem:
Sometimes when switching to graphical mode (either manually from a terminal via
alt-f7, or automatically whenever the server is started or reset), the display
appears corrupted. Specifically, certain colors get messed up. The white "f"
part of the fedora logo turns black, desktop icon names have noisy black/white
Manually switching to text mode and back usually cures the issue.
Version-Release number of selected component (if applicable):
How reproducible: about 1 time in 20
Steps to Reproduce:
1. switch to a text console (alt-f1) then back to the graphical mode (alt-f7)
Certain colors are wonky.
This can also happen whenever the server is started, either when booting into
level 5, or when the server is restarted after a session logout, or when the
server is restarted via alt-backspace.
This is a clean install of F7 on hardware (GeForce 6200) that worked normally

Looks interesting -- could we get /etc/X11/xorg.conf as well? What happens when
you have no /etc/X11/xorg.conf whatsoever and you restart X?
(BTW, for airlied, whom I am going to assign this bug, we've got reproduction of
this bug from a developer in the Brno office).
I don't think this is anything to do with configuration. It looks more like the
palette is getting stomped either on EnterVT or LeaveVT.
Yep, there is probably some problem in the code. I'm observing the same with my
GeForce 6200. For the record, my config is
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
Viewport 0 0

And here's my Xorg.0.log.

Sorry for the hit and run -- somehow BZ emails weren't getting to me until this
Attached my xorg.conf, but it's trivial.
Also, this problem is sometimes triggered by gnome-screensaver's fade-to-black,
even if it gets interrupted by pressing a key before blanking completely.
Also, when the problem is active, if I run a small program which changes video
mode to 8-bit and then changes back on exit, the problem is cleared.

server log for no-configfile case
It took me 5 minutes to confirm that the problem occurs without any xorg.conf
file. Log attached.
This seems to be fixed for nv in F8. (It happens for nouveau on F8 instead.)
Close as nextrelease?
