           Summary: Rotation crash with driver 6.7.191

          Platform: x86 (IA32)

Been testing latest driver from xrandr 1.2 branch (or master now), version
6.7.191, compiled by Timo for Ubuntu gutsy.
http://ubuntuforums.org/showthread.php?t=532831

System:
Ubuntu Gutsy as of 23. august 2007.
Thinkpad T42 with Radeon 7500 32mb.
LVDS 1400x1050 50hz
DVI flatpanel 1280x1024 60hz

Tried rotating the panel, both the LVDS without DVI connected, and the DVI
panel with LVDS off. Both crashes my computer, and I have to power off.

I noticed an warning when trying to expand my desktop by the 2 screens:
xrandr --output LVDS --mode 1400x1050 --right-of DVI-0
gives: Supported resolution only 1600x1200 requesting 2680x1200.

After powering off the LVDS and requesting rotation on DVI-0, same error
occured. I then lowered resolution on DVI-0 to 1024x768 and rotated, computer
hangs!

More I noticed in clone-mode, the DVI-0 panel behaves normal, but the LVDS is
like stop-motion, like its showing only half the frames of the DVI.
Windows handles both clone-mode and desktop-expand great, so the card is
capable.

What info can I provide?
