I'm also experiencing the same issue with the following messages in xorg.0.log: "RADEON(0): [agp] AGP not available" "RADEON(0): [agp] AGP failed to initialize. Disabling the DRI." "RADEON(0): [agp] You may want to make sure the agpgart kernel module is loaded before the radeon kernel module."
I found that enabling the Control + Alt + Backspace option to restart the X server followed by pressing Control + Alt + Backspace allowed me to log back into Ubuntu with 3D acceleration working second time round. As this requires logging in twice I will probably try the other work arounds mentioned above but a proper fix would be appreciated. -- Radeon module loaded before agpgart https://bugs.launchpad.net/bugs/468413 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
