Screen Resolution shows wrong refresh rates

Bug #82995 reported by oslo on 2007-02-03
Affects Status Importance Assigned to Milestone
xresprobe (Ubuntu)

Bug Description

Binary package hint: xorg

While my monitor tells me a current refresh of 85Hz, the only options I have in the Screen Resolution are 50 and 51Hz..
monitor: 1280x960 86KHz 85Hz while Screen Resolution Preferences window shows 51Hz. If I change that to the other available option, 56Hz, the monitor enters a "new mode" (doesn't show the resolution) working 60Khz and 60Hz. As the screen flickers I assume 60 being correct. However it still isn't the resolution I have chosen from the Screen Resolution Preferences window

This is odd..

Does disabling "DynamicTwinView" in /etc/X11/xorg.conf (as described in Bug #92599 / Bug #104105 ) make any difference?

Hi Sitsofe,

I'm sorry for the terribly late response, I had a long holiday off
-without my own computer-...


Turning off DynamicTwinView did the trick!

Thanks for your advice!
