Red Hat Bugzilla – Bug 3497
lower part of display looks distorted
Last modified: 2008-08-01 12:22:51 EDT
hardware: ultra1 (ultrasparc)
software: rh 6.0: kernel-2.2.5-22, XFree86-Sun-18.104.22.168-49
symptom: the bottom say 20-30 lines of the display look
distorted, because everything is drawn with a shift to the
left, but this shift is different for different types of
graphics (pixmaps, fonts, etc).
notes: I'm really not sure if this is related to X or to the
framebuffer. AFAIR the problem appeared with kernel 2.2.5.
It was not there while we used Ultrapenguin 1.1.9.
The problem is also not observed with rh 6.0 (same rpms as
above) on a sparcstation4.
Try out the XFree86-22.214.171.124-52 packages and see if they remedy the
problem. Reopen the bug if you are still having problems.
The problem remains the same with the XFree86-126.96.36.199-52 packages.
What framebuffer device is in this machine?? Also, what X-server are
you running on this ultra?
/proc/fb reports: "0 CGsix"; this is an sbus framebuffer.
The X-Server is the one from XFree86-Sun-188.8.131.52-52.
Kernel ist still kernel-2.2.5-22 for sparc64.
(~162k) shows a screenshot to illustrate my problem.
In bug #2446 my problem is already reported by someone else (as an
problem which occurs in a system with two CG6-framebuffers).
Hope this helps.
Since kernel 2.2.11 the problem is no longer observed.
