[nvidia-glx] Problems with refresh rate after installing proprietary nVIDIA drivers

[Stefan Markic]

Before I installed proprietary nVIDIA drivers, when I went to System-> Preferences-> Screen Resolution, I had a resolution at 1024x768 on 85Hz. Just like it's supposed to be. After installing proprietary nVIDIA drivers, my resolution was still at 1024x768, but on 50Hz. I switched that on 85Hz in nvidia-settings and when I went to System-> Preferences-> Screen Resolution to check it out, it was on 100Hz. Every time I make changes in nvidia-settings, I save them (/etc/X11/xorg.conf), and every time I restart X, it's always back on 50Hz at 1024x768 resolution.

This is getting really serious.

Thank you for your bug report.

Punting from Ubuntu -> linux-restricted-modules-2.6.20 because this is an nvidia binary driver issue.

Stefan:
Could you please attach the following file to this bug report:
/var/log/Xorg.0.log
?

This is probably a dup of other "nvidia resolution" bugs like Bug #91292 . The nvidia binary drivers seem to be rather weak at correctly detecting the correct monitor refresh ranges when compared to the open source nv driver...

[Stefan Markic (kcanic)]

Here's my /var/log/Xorg.0.log.

Stefan:
Does following suggestions outlined in bug #91292 help?

Well, here's mine:

Section "Monitor"
    # HorizSync source: edid, VertRefresh source: edid
    Identifier "Monitor0"
    VendorName "Unknown"
    ModelName "Hansol"
    HorizSync 30.0 - 72.0
    VertRefresh 50.0 - 160.0
    Option "DPMS"
EndSection

What should I put?

Stefan:
Is the tile of this bug accurate - is it about resolution or is it really about refresh rate? If it's the latter then I think I should have asked you to look at Bug #104105 ...

[Stefan Markic (kcanic)]

I'm having problems with refresh rate only.

Stefan:
Does making the changes described in https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.20/+bug/104105/comments/11 make a difference?

[Stefan Markic (kcanic)]

Yes, now it shows the proper refresh rate when I go to System-> Preferences-> Screen Resolution.

I added this at Section "Device" in xorg.conf:

Option "DynamicTwinView" "false"

So it now looks like this:

Section "Device"
    Identifier "Videocard0"
    Driver "nvidia"
    VendorName "NVIDIA Corporation"
    BoardName "GeForce4 MX 440"
 Option "DynamicTwinView" "false"
EndSection

Thank you.

Thanks for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug #91292 and is being marked as such. Please feel free to report any other bugs you may find.

[Rickard Nordbrandt (rickard-nordbrandt)]

comfirmed
fixed using Option "DynamicTwinView" "false" in xorg.conf

[Sitsofe Wheeler (sitsofe)]

That should have been bug #104105 ...
