Solved: Re: ATI Radeon HD 4290 (onboard) Only 60 Hz frequency

Hi List,

I solved the problem of having a display with 60 Hz only, the following way:
I, again, searched my xorg.0.log. This time, I noticed the entry:  ''fglrx(0):  
Display0: Failed to get EDID information.''
Google helped me to find: http://ubuntuforums.org/showthread.php?t=1577712

With that help and a minimal xorg.conf, and the program ''cvt'' (which makes you 
modelines for the xorg.conf, like ''~$ cvt -v 1600 1200 100Hz''), I now have a 
CRT monitor that runs on a vertical frequency of 100 Hz.


Hope this helps someone else.

Ulrich Grün.
