I'm new to Linux and recently installed 12.10 alongside Windows on my laptop.
Initially 3D screen effects (i.e., Docky) were not working and I tried different things like installing and reinstalling
Now, I think I messed up the display drivers completely. Although all the effects are now working, I can't get any screen resolution other than 640x480.
Can anyone please tell me how to find out exactly what's wrong and ways of fixing it?
