Public bug reported:

In Feisty Fawn bèta, release date 23-3-2007, I cannot make the frequency
of my TFT screen go higher than 50 Hz. Both in Edgy and in Dapper, this
problem doesn't happen.

Hardware:
Videocard: Nvidia GeForce4 MX 440
Monitor: HP vs17e  TFT screen 17 inch
The videocard is running on the restricted nvidia driver.

The first thing I did, was to install the restricted nvidia driver with the 
excellent built-in assistent, then reboot. At first, even the resolution of 
1280x1024 was unattainable. This I could only achieve after running the command 
sudo dpkg-reconfigure xserver-xorg in a terminal window. I had to put in some 
things manually in this reconfiguration tool, because it didn't automatically 
detect my videocard and monitor (in Dapper it did! Not so in Edgy: this known 
bug in the reconfiguration tool is still there, apparently). So far so good. 
Then reboot. 
Now I had 1280x1024, but still only 50 Hz.

Then I copied the correct xorg.conf from my Dapper partition into my
Feisty partition (both in Dapper and in Edgy everything runs fine at 60
Hz with this particular xorg.conf, also with the restricted nvidia
driver). Then reboot. Not even this worked!

Hope you can remedy this, otherwise I would have to stick with Dapper
and Edgy on my desktop....
