Having used Jaunty on and off for a while now on my laptop, I decided to install a fresh build of Karmic on my new desktop PC. I've had a few problems with this (the most annoying being the WLAN card not working!) but most of them I've fixed now after trawling for answers in the forums, but this one I just can't solve ...
Karmic doesn't appear to handle my graphics card very well (in fact it's pretty dire): I can't set the resolution higher than 1280x1024 (which looks seriously ugly on a monitor with a native resolution of 1920x1080) and I can't turn on any desktop effects (I think because the drivers aren't supporting it). Here's the output of lspci:
If I go to Preferences->display I get the following message:
$ lspci | grep -i '\<ati\>'
01:00.0 VGA compatible controller: ATI Technologies Inc Device 68f9
01:00.1 Audio device: ATI Technologies Inc Device aa68
...and trying to use the proprietary tool gives this error:
It appears that your graphics driver does not support the necessary extensions to use this tool. Do you want to use your graphics driver vendor's tool instead?
... and trying to run aticonfig gives this:
(I also get the same without the --initial option).
$ sudo aticonfig --initial
aticonfig: No supported adapters detected
According to Administration->Hardware Drivers, my current active driver is a proprietary one called rt3090sta.
Many of the forums (fora?) I've seen on this sort of subject mention xorg.conf. I don't know anything about this file, except that I don't have one:
Any ideas? I'm fresh out (not to mention really disappointed in my first impression of Karmic!).
$ sudo find / -name 'xorg.conf'
