I'm having a very strange issues with my graphics in kubuntu 12.04.

I'm almost certain a package has been downloaded which is disabling my default nvidia drivers and rendering my desktop using a very old or incompatible driver.

This is the end result I'm seeing Pretty shit right

So these are the steps I went through to get where I am and I have no idea how to proceed. 1. So the first step I thought was to reinstall my nvidia drivers from xswat's ppa in the hopes that it would override these changes. Sadly this didn't work.

  1. Ran 'nvidia-settings' where I am given a warning that the nvidia driver is not being used. Success! We now know what the problem is. Nvidia recommends to run 'nvidia-xconfig' and restart the xserver. Sounds simple enough.

  2. I run nvidia-xconfig (which seems to jsut rewrite my xorg.conf file). and I kill KDM entirely. I restart x with the startx command and were right back to step 2 with nvidia-settings complaining that the nvidia driver is not being used. NOTE: Is killing KDM overkill for shutting down xserver?

  3. I check out my xorg.conf file and everything seems in order.
