Thanks Cyril, your workaround works :) (with a small difference: I use gdm, so I've added instructions for reload radeon driver to my /etc/init/gdm.conf).
I've also found that extremely high cpu usage was caused by reloading not only radeon, but also ttm and drm modules. When I reload only radeon then Xorg starts normally with 3D acceleration enabled. -- 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
