I just installed PCLinuxOS on my husbands machine. It has an ATI 4850 Radeon Card. When I installed the os(dual boot with win xp) it showed in the hardware configuration that the 2xxx and above driver was being used but grapgics were choppy and slow. I ran the configuration again and chose the same driver and went through the process. I tried to test and screen went black. I restarted the comp and the boot screen went black to a command prompt. I am new to linux and don't know much so I reinstalled PCLOS. Catalyst Coontrol Center does not open. I have downloaded drivers from ati both the 10.5 and the 9.8 as I read that the older drivers work better but have no clue how to install them. Can someone please help?
