with driDevel enabled I got this problem on [ProSavage KN133](TwisterK)
5333:8d02 (rev 01)
with (default) Virtual 1024 768 on xorg.conf section display.
when switch to 800x600 (or 640x480) the image was correctly if virtual also
change to 800x600 (or 640x480) but has we know virtual stays in 1024x768 and
when I move viewport the image gets wrong (repeat left side).
with Virtual 800 600
Mode "800x600" also doesn't show image correctly but looks the same.
I think is just one problem of the resolution against virtual area of the screen.
where in source code can I find this calculations and init of Modes view ?
Can be with dri only.
well disable DRI doesn't help !
Others have reported that this is fixed in cvs. Can you try with xorg from cvs?
yes , it works correctly
The thing thats make me confused, is one bug on kde from fedora core 1, when
mouse pass over one window (for example one konsole), the mouse moves to one
wrong position. It difficult put in words how is the behavour of the mouse but
looks like a problem on display modes (only for mouse).
With gnome works has we expect, perfectly .
