Red Hat Bugzilla – Bug 198895
RX2600 display problems with Radeon card (itanium)
Last modified: 2009-06-19 04:31:38 EDT
On the RX2600 (an ia64 machine), after the initial installation, all the uses of
X show garbled display.
The problem looks similar to bug 182471, but only testing with the certified
machine would allow to verify that it's the same issue.
Xorg recognises the card as a "RV100 QY/Radeon 7000/VE".
The same card running in an x86 machine doesn't show any display problems.
X log attached.

I forgot to mention that adding the "Option XaaNoOffscreenPixmaps" line in the
xorg.conf corrected the problem.
Is it possible for someone to test whether the packages in
fix this problem?
XAANoOffscreenPixmaps is turned on for __ia64__ in
The original reported says:
"No, the newer xorg-x11 packages built (on an RHEL4u4 everything-install) do not
Note that the package doesn't change anything in the xorg.conf file. It simply
changes the default setting of the XAANoOffScreenPixmaps from FALSE to TRUE on
IA64 internally in the X server.
Yes, the change should be in 13.44.
Can you ask them to explicitly put
Option "XaaNoOffscreenPixmaps" "yes"
in the "Device" section of xorg.conf and see if that helps?
Nevermind that. The patch I applied was wrong. I'll fix this in 13.46. Sorry
13.46 is being built now.
I was defeated by the Xorg config API. Not only should 13.48 fix it, it will
also print useful information about it in the log file. So if 13.48 doesn't
work, please also attach the generated log file (but I really think it should
work this time).
Moving to 4.6.
"ugliness is seen" isn't really descriptive enough to know what the problem is.
Getting a hardware setup where we can reproduce this somewhere near me would be
helpful, but at a minimum we need to know what the failure mode actually is.
