MASTER: nVidia doesn't support Xrandr so monitor resolution is wrong

Bug Description

Description: Ubuntu intrepid (development branch)
Release: 8.10 (alpha-6)

gnome-display-properties uses Xrandr to set resolutions, however the proprietary nVidia driver doesn't implement Xrandr yet, and instead requires using its own configuration tool or editing xorg.conf.

Similarly, sometimes other client applications sometimes assume RANDR works universally and use it even on -nvidia. Various problems occur as a result.

[Original Report]
After installing Intrepid-alpha-6, the maximum resolution with 'gnome-display-properties' is 1024x786.

Resolution with Ubuntu Hardy was 1680x1050.

I could not find a way to change the maximum resolution. 'displayconfig' is obsolete. I will try to change xorg.conf, but is there an nicer way?

How about attaching your /var/log/Xorg.0.log? I have no idea what hardware you have..

with this lines added to my xorg.conf the resolution of 1680x1050 does work. with and without the nvidia-driver.

The core issue here is that nVidia doesn't support Xrandr, which is what gnome-display-settings requires for doing what it does. nVidia's Xrandr support is fairly limited (just rotation iirc), so until that's improved you'll need to use either nvidia's own configuration tools or edit xorg.conf directly.

I have had a problem with the nvidia drivers and my hardware ever since trying Intrepid at Alpha 5. So I reverted to the nv driver until yesterday. I thought I'd try again.

The problem is that I only get 1024x768 *every* time I reboot. Even if I use the nvidia-settings tool to change it to 1152x864 (which is better but the only other option I get is 1360x768). In the System->Preferences-Screen resolution, the only highest resolution offered is1024x768.

I have an Nvidia 9500Gt card and my Monitor (A Dell M991 CRT) is connected via a Belkin KVM on the VGA port. It seems that there is a problem detecting my monitor. Hardy (with an older Nvidia card [5200?]) used to work fine through the same KVM and with the same Monitor.

I've attached my Xorg.0.log.

If I can "fix" it by hand coding an xorg.conf that would be fine for now. But seeing how Intrepid seems to create a blank xorg.conf and gather all the needed data automatically I was unsure if my changes would be accepted or simply overwritten on each reboot. Suggestions gratefully accepted.

Tried it, this driver version still doesn't have full Xrandr support, so for this bug nothing changes.

This feature probably won't be added for the -177 driver series, as it has been removed from distribution on our part.
