Hello,
I'm having a problem with X since I own this computer and Michel
D\"anzer of the debian-x mailinglist advised me to mail to the Xpert
list to tell about my problem. So, here it is:
Whenever there is 'movement'/'action' on the screen (e.g. an openGL demo
from xscreensaver, an animation in Mozilla or a scrolling window) the
right side of the screen (only *right* from the cursor, about 600 pixels
to the right, i.e.) shows sort of 'ghost images': parts of the screen
that are about 300 pixel right of the cursor are shown on the right side
(shifted to the right about 510 pixels), flickering (there seem to be
chunks of 32 pixels in that flickering area), but only around the Y
position of the cursor (in vertical direction the flickering stuff is
having a height of about 64 pixels). When the screen action stops, the
effect is gone (I can't take a screenshot of it...)
Changing the screen resolution doesn't affect the problem. In
applications where the cursor is hidden, the effect stops immediately.
Once I was able to stop it: I added the Option SWcursor to my Driver
section of XF86-Config, logged out, pressed CTRL ALT BS and logged in.
It was gone, and I thought I found a solution. However, next time I
logged in (another day), the problem was far worse! So enabling SWcursor
doesn't help at all, but makes things worse!
Some system info:
I'm running Debian testing (always upgraded to the newest packages). I
have an Athlon XP 1600+ with VIA K7T266 Pro 2 mainboard and an ATI
Radeon SDR 32MB AGP videocard (I think that is now called the Radeon 7200).
I'm running X at 1600x1200x32@85Hz. My XF86Config-4 is config'ed with
debconf (except that I removed the Use FBdev stuff that is put there by
default).
The kernel is 2.4.19.
The problems were present since the beginning, I bought this computer in
December 2001. The upgrade from XFree86 4.1.x to 4.2.x didn't make any
difference.
These are log and config files I use:

(Actually, I now upgraded to experimental Radeon drivers, but that
doesn't make a difference, the problem persists...)
Some people suggested it is a monitor cable problem, but I don't think
that is the case, since the problem is very related to the cursor. (And
besides, I tried it with Windows which doesn't show any problems.)
If there's anything you can think of that is causing this weird problem,
please let me know! Also if you need more information or want me to run
some tests or measurements.
Thank you in advance for looking at it.
Best regards,
Manuel Bilderbeek
