This problem is also posted at Kubuntu forums; it's posted here to get wider audience (and hopefully quicker solution).
I just installed a PNY PCIeX16 nvidia 8500GT graphics card (was running off of m/b video). However, the only resolution I can get is either 1280x1024 or 640x400 -- I need the inbetween (1024x768). The 1280 is too small for my eyes and the 640 is useless.
I've tried using the nvidia-configuration app. I've tried using dpkg-reconfigure. I've copied lines from previous xorg.conf that worked with this monitor (different PC). I have two choices:
1. Use original xorg.conf (basically, no options) and all I get is 1280x1024.
2. Use my current xorg.conf.
A. during boot, one "Overrange" error displays but I can log in.
B. once I log out, I go to a black screen with just a mouse cursor.
C. If I <ctrl><alt><f1> and log in as root, I can restart KDM but I get A & B once again.
If I try and configure the adapter via kcontrol, it re-writes xorg.conf at the low resolution (even though I select 1024x768 -- I've verified this several times).
I'm at a loss -- I'd really like to get this working properly. The monitor is a Sceptre X7G-Naga V and the card is a PNY PCIeX16 nvidia 8500GT (512MB). Here is my xorg.conf as it's currently written.
As a side note, the OS was originally installed with the onboard graphics and using a different monitor. Is that a problem? Should I delete the xorg.conf? Using dpkg-reconfigure doesn't seem to help. Should I uninstall the driver (Kubuntu restricted driver manager installed the driver) and get the latest from nvidia?
Thanks for help.
