Hello. I cannot seem to run any linux desktop well with this chip on a 880G chipset motherboard. My bios is flashed to latest. Gnome Shell 3.2 on elementary os/ubuntu 12.04/deepin 11.12 ran and still run on the comp without performance issues with no lag or problems whatsoever. However Unity's desktop effects are very laggy. KDE's desktop effects are choppy and stutter. But other desktops like e17 run well with OpenGl acceleration, tear free and vsync without problems. But I want to mainly run Gnome Shell. But I tried the new Ubuntu Gnome 12.10 and 13.04 but the newer Gnome versions seem to be laggy/choppy. However Gnome 3.2 is also installed on my comp and runs well. Does anyone use any Linux with this chip? Can anyone please confirm whether the choppiness in new Gnome Shell is an actual issue caused by regression or whether somethings wrong with my install? I'm using the open drivers on all my installs and radeon should be able to handle desktop effects no problem. And it did in Gnome 3.2. I don't care for games. The catalyst is not an option as it has sub-par performance but is too buggy. Is anyone using Radeon hd4250 without problems? Can anyone help? Could it be this is Ubuntu-specific? Linux is no fun if I can't run my fav desktops.
Direct render is enabled as glxinfo says. Other specs is AMD 965BE 3.4Ghz x4,4GBram (512vram shared), Gigabyte GA-880GM-d2h BIOS version FF.
