I installed Ubuntu 10.10 (Was Kubuntu, but I installed Ubuntu desktop ) and it worked fine. Compiz was really smooth and Boot-screen was nice. Everything else worked nicely but 3D-games didn't work because I didn't install the ATI drivers. Now I installed the drivers and the bootscreen went lowres and it was text-only. Then I logged in and noticed the compiz was bit laggy. I tried Duke Nukem 3D HRP and it worked now, but it was too laggy to play. Is there any way to get the drivers work correctly? I have ATI Radeon HD4650 and in Windows 7, Duke Nukem 3D HRP worked very smoothly.
