Is there some things to fix mobility AMD Radeon HD3xxx series in Ubuntu 11.04 ?? Until now, i've been updated my system using Kernel 2.6.39-11 and Catalyst 11.7 but Graphics Effects sill running ugly in Ubuntu 11.04. I've try to Disable "VSync" and "Refresh Rate" in CCSM but still ugly. If i using standard driver (xorg-ati) my system usually freezes !! But if i using Catalyst driver, it's not happen again but have bad performances

Is there way to fix this?

What do u mean by ugly. I am and others are facing sluggish performance with ATI graphics card. Like switching windows using ALT+TAB and slow video performance. One bug has been filed for this issue at lunchpad. Right now it is in work in progress. So you can expect a fix in near future.

As I've understood it, AMD is in the process of moving to open drivers. On my HD5850, I've had big and frequent problems with the proprietary driver and it's been slow. The open driver has been faster, but not as stable. Now, though, the open driver seems to be working perfectly and is still a lot faster than the proprietary drivers. But again, as I've understood things, AMD is focusing on the newer cards first and then, probably, will go on to fixing HD series 4, 3, etc.

There is absolutely nothing anyone except AMD can do about the poor performance of their proprietary driver.

You say you're using xserver-xorg-video-ati? I would certainly try xserver-xorg-video-radeon a shot.

hmm... yeah, maybe like that because AMD also want to releases APU Product.. Yes, xserver-xorg-video-ati. If using that driver, the system usually freezes –  Ikhieasuka Aug 8 '11 at 8:58
