It doesn't list the Vertical refresh rate, try:
- Code: Select all
cat /etc/X11/xorg.conf | grep Vert
Or since you are using the proprietary ATi driver, maybe Catalyst handles this?
Anyway, the above code should return something like:
Vertrefresh 43.0 - 60.0
If it doesn't, then I'm not sure what to do, it's been ages since I last had a box with an ATi card...
