Red Hat Bugzilla – Bug 235181
resume from RAM causes 1 line screen corruption
Last modified: 2012-04-17 17:18:02 EDT
Description of problem:
When resuming a machine running the i810 video driver, a 1-line corruption
appears on the right side. It seems to be copying any data in this line to the
left side, about 50 pixels down. This is the exact same bug as #190307, except
in RHEL5. The associated X.org bug is:
System is a Lenovo T60 widescreen, model 6369-Y11. Screen is 1680x1050
Version-Release number of selected component (if applicable):
1. Boot machine using i810 driver
Line copies from right to left of screen/vice versa
The recommended fix from the freedesktop.org bug is to install the latest
drivers. I rebuilt 1.7.4 to see if it would work, and the corruption was still
there. I mananged to get the 'intel' driver version 1.9.94 to compile against
RHEL5 X server, and that did solve the problem but it is very unstable (as that
driver was meant for a 1.3 release of X)
If I disable DRI:
Option "DRI" "off"
the corruption also disappears, but I would rather not lose 3D support if I can
at all help it.

Corruption maps pixels from right side of screen to left side on a single line.
Richard, 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.
Reporter, could you please reply to the previous question? If you won't reply in
one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.

Any of the TX60 modes exhibit the corruption.

Sorry about the delay. I will have the "fresh" xorg.conf and Xorg.0.log in just
a few minutes.

This is the default xorg config

default xorg log, with error occuring
I attempted to run X with no xorg.conf, and it booted cleanly, but resuming from
the suspend consistently caused a kernel panic and/or infinite flashing "resume"
light with no resume.
Cool, wonderful informations ;-). I mean, sorry it doesn't work and we will try
to do something about it.
No further hardware enablement updates are planned for RHEL5's X stack. If this issue is still present in RHEL6, please update the affected product version field and reopen this bug.
