Hi Klaus Yes I have had Unity 3D working in Oneiric Beta. I think are are plenty of problems related to the Unity Plugin. It seems though to be a bit more stable after the latest Beta 2 updates have come through and been applied. Sometimes I have started CCSM, switched on say, Window Decorations or the Desktop Cube and have then tried to resolve plugin conflicts. This is the point where the system reports a Compiz crash. I think the best strategy is to uncheck the Unity Plugin in CCSM, switch on the effects you want, resolve any conflicts and then switch on the Unity Plugin again. Sometimes an attempt to start Gnome 3 instead of Unity 3D results in the Unity Plugin unchecking itself and then you have to start the whole thing once more from the beginning. This whole idea of the Unity Desktop being so dependent on a Compiz Plugin is not a wonderful idea IHMO. The thing is still fundamentally broken sadly. Gnome 3 will not run properly at all on my system even if gnome-shell is installed in its latest incarnation. On another subject entirely to you have a relative called Werner Reichl in Vienna? He runs a training centre here in Vienna and does Linux training there. MfG, Best regards Jack On 27 September 2011 20:04, Klaus Reichl
