Description of problem:
When logging out from a Gnome-based WM, two thick black lines appear running
from the top of the dialog box to the top of the screen.
Occurs at least on Dell Latitude C610 with ATI Radeon Mobility M6.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Log into Gnome WM
2.Select Logout from main menu
Actual Results: Dialog box appears with artifacts.
Expected Results: Dialog box should appear without artifacts.
I have the same symptoms on an "ordinary" Radeon 7500.
I also still can't select the 1400x1050 resolution. There was a bug report on
this a few weeks before (bug# 63593). Thought this would've been solved in the
This seems to be a RedHat problem. No prolems with -cough- Mandrake 8.2 -cough-
(also uses XFree 4.2).

The problem you are describing is due to a video driver issue of which
there is no solution currently. This problem is _not_ a Red Hat issue,
it is an XFree86 4.2.0 issue, and affects anyone using XFree86 4.2.0.
If the problem does not occur in Mandrake, then it is just not being
triggered by the specific GNOME code in Mandrake, however I assure you
that the bug exists.
Of course, you're free to use Mandrake if it pleases you.
I expect previous comment from mharris was about 1400x1050 resolution.
First this thread was about lines appearing on gnome logout. I have the same
with two other different cards: neomagic, matrox G450. Therefore I do not think
it is problem of graphic card.
The lines on the screen during GNOME logout are a known Radeon driver
bug. It does not crash anything, and it only shows up on the logout screen,
so it is not a major high priority. It's just ugly.
The issue is known to other developers and will likely disappear in
a future Radeon driver update, but it is not something worth troubleshooting
and fixing right now with much more important bugs open that actually can
I'm defering this for the future and will come back to it in a future
