hi, i’ve installed the last version of opensuse on my notebook acer Travelmate 5720 with graphics card Ati Radeon 2400 XT.
The 3d effect are disable and if i try the tool 3ddiag, the result is No 3D capable graphic chipset found ( but is a 3d graphics card !!! )
i’ve download the driver 8-12-x86.x86_64.run from the ati site.
thank all for the help and sorry for my bad english !!!
