[nvidia-glx] screen frequency/refresh not higher than 50 Hz

[Pjotr12345]

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....

Thank you for your bug report.

Pjotr12345:
Please could you upload the following files when the fault happens:
/etc/X11/xorg.conf
/var/log/Xorg.0.log
to this bug report?

Setting to needsinfo pending Pjotr12345's reply.

Really setting to needsinfo.

It seems that the frequency is actually higher than the 50 Hz reported by Ubuntu in System - Preferences - Screen resolution. When I call up the BIOS of my TFT screen, by pressing the physical button on my TFT screen, it shows that it is running on 60 Hz (which is the ideal frequency).

I have attached the requested files. The problem is not related to Beryl, by the way, as the problem already occurred before I installed Beryl.

Greetz, Pjotr.

and the other requested file....

Punting from Ubuntu -> linux-restricted-modules-2.6.20 . Moving from needsinfo -> unconfirmed.

Could you include the output of
dpkg -l nvidia\* | grep ii

Soudns similar to Bug #104105 ...

[Pjotr12345 (computertip)]

OK. This is the noutput:

:~$ dpkg -l nvidia\* | grep ii
ii nvidia-glx 1.0.9631+2.6.20.5-15.20 NVIDIA binary XFree86 4.x/X.Org driver
ii nvidia-kernel-common 20051028+1ubuntu7 NVIDIA binary kernel module common files

Can you indicate whether following the instructions in https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.20/+bug/104105/comments/9 made any difference?

[Sitsofe Wheeler (sitsofe)]

Setting to needsinfo pending reply from Pjotr12345.

[Pjotr12345 (computertip)]

As suggested, I added the following line to the Section "Screen" of my xorg.conf:
Option "DynamicTwinView" "FALSE"

Then I restarted X. The problem was solved!
The indicated screen frequency in System - Preferences - Screen resolution, was automatically changed to the ideal 60 Hz.

Thanks, Pjotr.
