The main issue is these lines in your XorgLog: (EE) intel(0): [drm] Failed to open DRM device for : No such file or directory (EE) intel(0): Failed to become DRM master.
I've been seeing this bug occasionally on my system too, since the new upstart stuff. When booting, KMS fails to set the mode, so I see boot messages in low-res text mode. GDM then starts, but as you say, X is very slow, and I think you'll also find that anything that tries to use DRM (eg. playing a movie in Totem or VLC) will cause X to crash. Somebody else reported similar problems as part of https://bugs.launchpad.net/ubuntu/+source/udev/+bug/430654 and it was suggested that a separate bug report be opened. I'm not sure if this is that separate bug report.... -- xorg is slow since new upstart https://bugs.launchpad.net/bugs/431178 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
