Screen resolution problem after upgrading ubuntu

fivemack · 2008-04-30, 22:55

I pressed the 'upgrade' button to get from 7.10 to 8.04 on my main workstation (P35 motherboard, nvidia 7300 graphics card using nvidia driver)

It restarted in 800x600 mode; the 'screen resolution' applet won't let me change to any other resolution, and the nvidia-provided driver configuration applet denies that I'm using the nvidia driver - it gives me an instruction which it claims will cause me to use the nvidia driver, I have to run some program and then restart the X server, but when I do that it still denies that I'm using the nvidia driver.

Any ideas?

Have alook at /etc/X11/xorg.conf

In particular look at the "section" "Device". For the free driver "Driver" is "nv" and for nVidia's it should be "nvidia". HTH

Also do "apt-cache search nvidia". I think the latest software from nvidia comes in two parts: the driver and the applet for resolutions.

You can also try using envyng to install and configure the driver for you. Search for envy in Synaptic and install it and the corresponding GUI.

I've tried using envy; it reports success, but when I reboot I get the box saying that my graphics card and monitor could not be detected, and here I am in 800x600 with the vesa driver, with nvidia-settings telling me that I'm not using the nvidia driver.

xorg.conf file is attached.

If the large processing jobs didn't have to be restarted every time I fiddled with the X driver, that would also be good ... I suppose I should have ssh'd in from another machine and started them there, but fiddling with X appears to involve lots of reboots so I'm doomed anyway.

I notice that envyng didn't install the package of restricted kernel modules, so I'm trying that.

My Ubuntu 7.04 xorg.conf has:

Code:

# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

Also have a look at /var/log/Xorg.0.log

fivemack,
you do not have to kill your jobs if you run them in consoles. I run two LL jobs by logging on in text mode on console Ctl-Alt-F1, start the first job, then log on to Ctl-Alt-F2, and start the second job. Then log on to any console Ctl-Alt-F3 thru -F6, and then start X. Then you can stop and start your X without killing the other two jobs.

You can also use the init.d scripts to run llr on boot :)
