After installing Ubuntu on my Laptop with a HD540v card, I chose the proprietary FGLRX non post-release updates driver which showed graphics errors mainly in the taskbar. I took advice to install the newest Catalyst driver which I did. I now have severe flickering when switching programs or hitting the Windows button. I hear the open source driver helps but it cant cope with Catalyst performance-wise. What do you suggest I do?
