I'm hoping someone can help me repair my Gallium graphics driver for an ATI Radeon 3200 series card on Mint 14. Currently, I cannot run any program that uses OpenGL such as Minecraft or SketchUp 8. My problems started when I wanted to try the official AMD driver to get better framerates in my games and apps. I installed the driver successfully, but it disabled Cinnamon and forced me to use GNOME. So I uninstalled the driver, but none of my OpenGL apps work now. I have read that the probable cause was that the AMD driver removed those features from Gallium and replaced them with its own. So now I need to fix it. All suggestions are welcome. Thanks.
My setup is:
Machine: HP Pavilion dv7-1448dx laptop
CPU: AMD Turion X2 64 2.20GHz Dual-core
GPU: ATI Radeon 3200 Graphics
OS: Mint 14 & Windows 8 dual boot
