ATI Radeon Mobility 7500
Hi, I know there are lots of people having problems getting ATI cards to work in Linux, but I was wondering if anyone by chance has gotten the Radeon Mobility 7500 to work? I'm running Ubuntu Dapper Drake. I'm getting weird dots on all my buttons (OK, Cancel, etc), but those go away when move the mouse over them. Also, it doesn't want to run at any resolution above 1024x768 60Hz without a lot of problems - that's pretty annoying. I know it's not a hardware failure issue because everything is working fine in Windows XP. Can anyone please offer some advice or a guide or something? (Be detailed please, I'm an extreme Linux newbie) Thanks!
