nVidia driver only giving 640x480 and 320x240


On my MythBuntu box i have an nVidia Quadro 4 graphics card. I installed the restricted driver through Applications > System > Hardware Drivers and rebooted. Now I get two resolution options: 640x480 and 320x240.

I tried installing envyng:

Code:
sudo apt-get install envyng-gtk
I had envyng install the nVidia driver based on automatic hardware detection, and i rebooted. envyng removed the drivers installed by the Ubuntu Restricted Drivers application and instead installed another driver, but the end result was the same; only the two resolutions.

I installed the nVidia graphics control panel to see if that would change anything:

Code:
sudo apt-get install nvidia-settings
But no change - only the two resolution settings.

I tried installing, uninstalling and reinstalling the drivers using Ubuntu's Restricted HW tool and envyng several times, but no luck.

---------------------------------------

Some basic information:

Code:
~$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=8.04
DISTRIB_CODENAME=hardy
DISTRIB_DESCRIPTION="Ubuntu 8.04.1"
Code:
~$ uname -a
Linux mediBuntu-Frontend 2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686 GNU/Linux
Code:
~$lspci | grep VGA
01:00.0 VGA compatible controller: nVidia Corporation NV28GL [Quadro4 980 XGL] (rev a1)
My system is up to date and I do have a working internet connection.

The graphics card has two DVI outputs and I'm using a DVI->VGA adapter to connect to my monitor (a Philips 170B LCD monitor) via a KVM switch, so I'm guessing that corrupted EDID info is not the issue (since the analog VGA monitor input doesn't send out any EDID info back to the graphics card?).

Hi,

Could it be a problem with your monitor configuration/detection ratter than your graphics card? Try opening a terminal and type the following:

sudo displayconfig-gtk

Setup your display properly, logout and login again. I had to do that, because some fullscreen games in wine were running out of sync.

Regards!

Sorry I do not have access to my Nvidia machine for specific names but maybe I can give some help. My Shuttle SN68PTG Deluxe has Nvidia video and main board chipset. I hope what I experienced may apply to your computer.
Assuming you do not want to mess with scripts and xconfig changes that may be overwritten at next boot, what I did may be for you. To get correct resolution, use Adept-Manager to install Nvidia driver and Nvidia control panel. After proprietary Nvidia driver installs, run Nvidia control panel, set resolution you desire. Log out, restart X & log in. If you do not restart X, just reboot, it may not work.
I have two monitors that are recognized by Kubuntu as correct name & correct resolution. Without Nvidia driver and control panel, Kubuntu 8 wants to run less than native resolution on each monitor on VGA cable & on DVI cable.
In Debian, I had same issue, same cure, so it may not be specific to KDE or Ubuntu.
May not even apply to your Nvidia.

Quite correct, changing the display from "Plug 'n play" to a generic display 1280x1024 fixed the problem.

Setting up a different box with vanilla Hardy in the same setup (same LCD panel through the same KVM switch) yielded the same problem, but again; manually selecting a 1280x1024 capable display instead of the (apparently) default "Plug 'n play" display fixed the problem.

Also; when connecting my MythBuntu box to my 1920x1080 TV the resolution was automagically set to 1920x1080, without me having to lift a finger - that's some nifty stuff! Seems like I was making it harder than it had to be...

Must be nice to have cooperative system. Mine would refuse correct resolution setting or accept correct resolution setting then change to lower resolution at next boot.
