Thanks, Timo. Your suggestion brought me to the solution of my problem. I had the same problem and fixed it by uninstalling xserver-xgl after reading Timo's post. After uninstalling it, I was able to log into any Desktop Environment I had installed (Gnome, KDE, XFCE) without any error messages. Even the gnome-setting-manager error message is gone. Desktop effects work also just fine now.
I have an ATI Radeon Mobility 9600. I hope this info helps others to resolve their problems with this error message as well. -- cannot logon to GNOME https://bugs.launchpad.net/bugs/191057 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
