I'm having a few minor issues with the ATI driver in Mint 7 Gnome 32-bit. It could not play DVD's without freezing and stuttering. I am currently using an HD 3870, but when I had a 9800GT (Nvidia) everything worked fine.
Removing mplayer and movie player and using Kaffeine with the visual effects on "none" allows it to play movies correctly. The "display" tab won't open, but I am able to use the ATI CCC to set up things the way I like them.
I downloaded the linux version Cat 9.6 from AMD/ATI but have no clue how to install it. The only way I now how to install is using the synaptic, a ready to go DEB format, or sudo apt-get install/remove from the terminal. So far that has gotten me far enough, but any other way is completely alien to me. Unloading the FGLRX graphics driver works for desktop duties and movies as well as enabling the "display" tab. But then the visual effects still can't be used and the screensaver is noticeably lagging because of lack proper 3D support.
Can anyone explain how to install the Cat 9.6 in terms that I will be able to understand? Remember, unwrapping, compiling and such terms mean absolutely nothing to me, I am still a noob at linux. Thank goodness for the awesome out of the box performance and compatibility of Mint 6 and 7! Only because of that as well as the ease of updates and synaptics, I am actually able to use and enjoy linux so much better than Winblows.
