comment What should I do when Ubuntu freezes?
If your video driver is using kernel modesetting (KMS), it's unlikely this will be sufficient to fix lockups, you have to use sysrq or power cycle. (Go ahead and try C-A-B, it obviously can't hurt; it does work when an app (like compiz/unity) is stuck, rather than X itself, however other answers on this page would be better in this case). But when it doesn't work, now you know why. :-)

Also, your /var/log/Xorg.0.log might shed some light on the situation. It sounds like your GLX module is loaded properly but it's possibly the log will show a revealing error message.

Ok, well I think /usr/lib/nux/unity_support_test -p failing is likely why unity isn't starting up. A backtrace might give some clues (i.e. gdb /usr/lib/nux/unity_support_test ; run -p ; bt full)
