Ok.
I am not sure, maybe I should file a bug somewhere in the 'nv',
'nvidia'
driver area. However, this bug seems to trigger with xfce4 only.
Well, could you try in metacity or openbox, wich support xinerama pretty
well?
I have tested with openbox. This allowed me identifying the problem a
little bit further. The issue is still reproducable in openbox when I
use the xfce4-terminal there. Further, I have noticed that when dragging
any other windows over this terminal their decorations get damaged, too.
Now I am quite sure that this is nvidia driver problem. There has to be
some window redrawing function that xfce4 uses that triggers this bug.
Should this still be reported to xfce4 bts to work around for broken
nvidia drivers?
Well, the xfce4-terminal thingy looks like a problem in compositing (or maybe
in vte). I know that I've asked multiple times yet, but is compositing
deactivated in xorg.conf? Like:
Section "Extensions"
Option "Composite" "Disable"
EndSection
Oops, I have NOW explicitely disabled compositing and the redraw issues
are gone. Well, I think you can close this issue. I am attaching a
working configuration file for xorg, so that anybody having this probe
is able to find a solution to it.
I would be more happy if there was some working solution for dualhead
for nVidia GeForce 6200 so that I wouldn't have to use the proprietary
driver. But as of now, I didn't find any, so I have struggle with this bug.
Yup, that's the problem with crappy proprietary and non documented hardware :(
I hate proprietary hardware, too..
Cheers,
Thanks a lot for support,
Jan
