Red Hat Bugzilla – Bug 216759
display completely garbled when using Xen kernel and ATI driver
Last modified: 2007-11-30 17:11:49 EST
Description of problem:
Since the upgrade this morning to xorg-x11-drv-ati.i386 6.6.3-1.fc6 I get
complete garbage on my screen when booting kernel 2.6.18-1.2849.fc6xen. There
are no problems when I use a non-Xen kernel (2.6.18-1.2849.fc6).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Xen kernel
2. Install xorg-x11-drv-ati.i386
garbled display (both X *and* console)
Nothing, should work "as normal"
The PC is a Medion MD8080. According to lspci:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R350 [Radeon 9800
I seem to be having a similar problem. I just installed FC6 on my Thinkpad T43
(with Radeon Mobility M300) with Xen enabled. It worked fine until I installed
all the updates.
One of the updates caused my X session to shut down, but then it didn't come
back; instead, the laptop display shut off entirely. I could still log into the
laptop via ssh, but couldn't figure out how to get the display to turn on again.
chvt 1 didn't help.
So I rebooted, and as soon as rhgb started up the display shut down again. So I
disabled rhgb, rebooted, and it booted normally until it started the X server,
at which point I lost the display again.
Reverting the ATI driver to 6.6.2 didn't fix the problem. Switching to the
non-Xen kernel did.
With kernel-xen-2.6.18-1.2868.fc6 I still see this problem. With the non-Xen
kernel it works fine.
Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

Running without xorg.conf it has the same problem.

log of lspci -vvv
I don't know if the output for lspci will help you, but I have attached it just
Reporter, are you able to reproduce this bug with latest update of your
distribution (meaning, after running 'yum upgrade' with whichever supported
distribution you have -- FC6, F7, or Rawhide)? Please, if you experience this
problem on the up-to-date system, let us now in the comment for this bug, or
whether the upgraded system works for you.
If you won't be able to reply in one month, I will have to close this bug as
INSUFFICIENT_DATA. Thank you.
I can't reproduce it on my Fedora 7 system and I'm not willing to downgrade to
FC6 to investigate this bug :-)
So, feel free to close it.
