System Settings -> Monitor & display in Kubuntu shows wrong information

[Toni Helenius]

Kubuntu's system settings reports resolution and the driver wrongly in System Settings -> Monitor Display. Instead of 1200x800 it says 640x480, and instead of NVIDIA it says NV.

Using Kubuntu Hardy on Toshiba Satellite A100 with GeForce 7300GO @ 1200x800 resolution.

Can you please run "displayconfig" from a terminal (please verify that you still experience the same behaviour) and attach the generated output.

[Toni Helenius (toni-helenius)]

I did it on a desktop computer with Kubuntu Hardy this time. It has C2D, GeForce 7900GS @ 1600x1200 and also jockey generated xorg.conf. And the symptoms are the same, "displayconfig" shows 640x480 and NV instead of NVIDIA and 1600x1200.

However the displayconfig didn't give any output.

[Andreas Wenning (andreas-wenning)]

This doesn't look to be very easy solveable. As guidance displayconfig is being replaced by a different KDE4 application in Intrepid, no further displayconfig changes are currently being considered. I'll however keep this bug open.

The problem might be that it doesn't detect the installed (proprietary) nvidia driver no your system. How is the driver installed; from source or using a package from the repository (and which one as a number of them exists)?

[Toni Helenius (toni-helenius)]

It's installed by Jockey on both systems. I hope KDE 4 will solve many of the problems what seems to be caused by old code and new architectures...

[Andreas Wenning (andreas-wenning)]

It should do better with KDE4 as it is written for the new architecture.

Can you try figuring out which nvidia packages you have installed? They are usually called "nvidia-glx*".

[Toni Helenius (toni-helenius)]

NEW ones on both computers. I don't have access to them right now but nvidia-glx-new I think was the proper name.

[Andreas Wenning (andreas-wenning)]

Looks like the moving of driver files has caused it to not detect that the nvidia driver is installed.

Please test the package I've put in my PPA: https://launchpad.net/~andreas-wenning/+archive

[Toni Helenius (toni-helenius)]

Did I do it correctly? I downloaded all the 3 packages, installed with GDebi and rebooted.

If I did, the patch doesn't work. All is still wrong.

[Andreas Wenning (andreas-wenning)]

Check that the correct version of the package is installed with "apt-cache policy guidance-backends"?
Was nvidia-glx-new the package name for the nvidia driver that is installed on the system?

[Toni Helenius (toni-helenius)]

I attached the output of apt-cache policy guidance-backends. If I understood correctly, the installation was successful?

Yes, the installed driver is nvidia-glx-new for both of the computers.

[Andreas Wenning (andreas-wenning)]

Are you running 64-bit ubuntu (copy the output of "uname -a")?
Please also attach the output of "dpkg -L nvidia-glx-new".

[Toni Helenius (toni-helenius)]

No, Kubuntu Hardy 32-bit.

[Toni Helenius (toni-helenius)]

Here is the output of "dpkg -L nvidia-glx-new".

[Andreas Wenning (andreas-wenning)]

@Toni
It could be that your card isn't known by the displaymanager. Please provide the output of "lspci -nn" so I can check.

[Toni Helenius (toni-helenius)]

Here is the output. If this helps, I can provide you too with the other computer's listing.

[Andreas Wenning (andreas-wenning)]

Strange; that card is in the table. I'm mostly out of ideas for why it fails to show which driver you are using. You do have a /etc/X11/xorg.conf on the computer from which the previous lspci output is from?

[Andreas Wenning (andreas-wenning)]

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks again!

Also, kde-guidance (displayconfig) has been removed in intrepid.

[Toni Helenius (toni-helenius)]

Fair enough, maybe it's not worth fixing for. I hope KDE 4 will solve the problem.

Sorry, I forgot all about this. The /etc/X11/xorg.conf reguested can be found in the first post as an attachment.

[Andreas Wenning (andreas-wenning)]

There is a completely new displayconfig in intrepid, which works with the new xorg-versions and xrandr; so it is really a lot better than displayconfig in hardy, that actually needed a completely rewrite to work with the new xorg technologies.
