Same symptoms started to appear here at the same time (yesterday), but the hardware is different (Intel/Intel/laptop vs. ATI/nVidia/desktop) and I run X the normal way (via gdm). I see the bug sometimes when I use the "switch user" feature (no keyboard or mouse at gdm login screen).
I had a look at the logs, and the only difference to successful starts is the aforementioned line: (EE) config/hal: couldn't initialise context: unknown error (null) Once, it was preceded by: [config/dbus] couldn't take over org.x.config: org.freedesktop.DBus.Error.AccessDenied (Connection ":1.129" is not allowed to own the service "org.x.config.display2" due to security policies in the configuration file) All I can do is kill the X with Alt+SysRq+K, but then it's pure luck whether this crashes i915 or not. ** Attachment added: "lshal.txt" http://launchpadlibrarian.net/32324376/lshal.txt -- hal error makes xorg unusable https://bugs.launchpad.net/bugs/434721 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
