Right, the second problem I'm having with this default install of Linux Mint 6 is with the ATI graphics card (an HD4850 512MB thing) - I tried the proprietary driver process, twice. Both times, no luck.
First time (after a little while downloading, or perhaps trying to), a small window came up showing a solid red circle containing a white dash, and nothing else. Second time (soon after) it did absolutely nothing. That I could see, that is.
I've noticed that there is an entry for 'ATI Catalyst Control Center' in my list of apps (on the start menu)... so, either that was there to begin with (unlikely), or it got put there, most likely during the first attempt to install said drivers and stuff.
So, what happened, and what do I do now, given that I want to be able to use the 3d capabilities of the graphics card, and at the moment, can't?
