I see screen corruptions pretty simliar to the ones in the attached screen shot.  Happens with both gnome and kde.  desktop effects are turned off.  dmesg and /var/log/messages are attached.  /etc/X11/xorg.conf doesn't exist.

Please, upgrade to the latest version of packages. I have observed this bug myself and with

xorg-x11-server-Xorg-1.7.7-3.el6.x86_64
xorg-x11-drv-intel-2.11.0-4.el6.x86_64
kernel-2.6.32-31.el6.x86_64

I cannot reproduce it anymore.
Comment 9 Bob Kozdemba 2010-06-02 17:21:43 UTC 
After upgrading to the latest packages mentioned in comment 8, the distortion problem has gone away. Thanks!

As a side note, the X-server now behaves slightly different when my T500 is docked with an external monitor. X appears the span the entire 2 displays (3360x1050) when the T500 lid is closed. I will experiment with settings.
Comment 10 Gerd Hoffmann 2010-06-03 11:32:31 UTC 
Corruption is still there for me.

[root@rincewind ~]# rpm -q xorg-x11-server-Xorg kernel xorg-x11-drv-intel
xorg-x11-server-Xorg-1.7.7-3.el6.x86_64

[root@rincewind ~]# uname -r
2.6.32-32.el6.x86_64

It seems to have improved though, I think older versions had more corruption.

screen shot

kde desktop, panel on the bottom is dissorted.

older versions had corruptions elsewhere on the screen too (browser images for example) which seem to be gone now.

Comment 13 Bob Kozdemba 2010-06-03 13:59:11 UTC 
Regarding comment 9, I should mention that ran 'yum update' against the nightly builds repo on the morning of 7/2/2010 so all my packages were updated.

Could I get logs as mentioned in the comment 2 from you as well, please?

Thank you

dmesg 2

See comments 3,4,5 ...
Attaching dmesg again (changes: new kernel & iommu enabled).
Comment 16 Gerd Hoffmann 2010-06-04 20:51:00 UTC 
Updated to Beta2-1.0 (aka compose 20100603.0).
Corruption is still present.

Comment 18 Dave Airlie 2010-06-11 06:28:28 UTC 
migrating to intel driver, not likely a server bug
Comment 19 Dave Airlie 2010-06-25 01:25:17 UTC 
can you try with xorg-x11-drv-intel-2.11.0-6 that is just built in brew.
Comment 20 Gerd Hoffmann 2010-06-25 08:52:56 UTC 
Doesn't fix the corruption for me.
Comment 21 Dave Airlie 2010-06-28 01:43:01 UTC 
can you boot with intel_iommu=off and still see corruptions?
Comment 22 Adam Jackson 2010-06-28 15:23:15 UTC 
You haven't attached /var/log/Xorg.0.log, which would tell us what graphics chip this actually is (though you've attached /var/log/messages, which is useless).  Please attach the X log file.
Comment 24 Dave Airlie 2010-06-29 00:03:59 UTC 
Its a GM45 if I had to guess from the other T500 I've seen.

Comment 26 Gerd Hoffmann 2010-06-29 10:18:33 UTC 
Changing intel_iommu doesn't change anything.  No matter whenever I boot with "on", "off", or "on,igfx_off" -- corruptions are present.

Gerd, have you KDE compositing enabled?
Comment 30 Gerd Hoffmann 2010-06-30 06:34:58 UTC 
compositing is disabled.
Comment 31 Gerd Hoffmann 2010-07-05 10:03:29 UTC 
Updated to RHEL6.0-20100701.0 compose  ->  corruption is gone.

> Updated to RHEL6.0-20100701.0 compose  ->  corruption is gone.    

I'm not totally happy with that explanation; I don't know of anything new in that compose that should have solved this.  Gerd, are you still running with the driver from comment #23?  What's the EVR of the xorg-x11-driver-intel package you're running?
Comment 33 Gerd Hoffmann 2010-07-06 16:10:44 UTC 
I'm running xorg-x11-drv-intel-2.11.0-6.el6.x86_64 (comment #19).

The comment #23 driver didn't work for me, see comment #27.
Comment 34 Dave Airlie 2010-07-07 23:03:35 UTC 
I think the iommu fix in the kernel fixed this, since the problem on Cantiga is the shadow GTT would get updated with bad pages and could cause rendering issues.

Sounds plausible enough for me.
