I have installed Linux Mint on a PC with a built in ATI graphics chip and have had problems installing the restricted driver so that I can activate desktop effects. The problem being that after installing the restricted driver it boots up until where you would expect the login screen and then goes to a blank screen. ( Note I can get to terminal from the blank screen). I tried several methods of installing the driver, Envy, Manual from ATI site etc etc and followed the various tips in the forums re black screens with ATI drivers to no effect.
Given that I have had bad past experience with ATI cards in Linux I then went for what I thought would be a simple solution and and installed an Nvidia 8600 video card but guess what , exactly the same problem with this- boots up until just before login screen then goes to black screen. If I go into xorg.conf and change the driver from "nvidia" to "nv" it boots fine but then of course no desktop effects.
I'm wondering if it has something to do with the monitor which is a no name LCD TV/Monitor which apart from the resolution I have not been able to find any info for and unfortunately I don't have an alternative monitor to try it on at present.
Mint is a great distro and would really like to get the restricted driver working, any help much appreciated.
