Hi, now I tested deaktivating my Xorg.conf !!!
I got a better result: CPU is "only" about 80-90% CPU usage (intel PIII 1 GHz) when starting e.g. firefox. It goes down to appr. 15% in normal usage after appr. half a minute. That is not acceptable - but system works ;) All in all performance is very slow, especiallly when starting programms, subscreens. glxinfo | render gives me: direct rendering: Yes OpenGL renderer string: Software Rasterizer Greets Axel ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/32023180/Xorg.0.log -- [i830] xorg hang on i830 video driver 2.8.0 https://bugs.launchpad.net/bugs/403037 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
