Looks like your laptop equipped with Optimus chipset. If you are have option in BIOS to disable nVidia that would be one of the solutions.
More info you can find there . I recently read that it is possible to use Optimus with Bumblebee, but I'm not sure if it was an F17 or F18.

switched to akmod-nvidia recently because the 3.6.10 driver did not
come but this did not change anything).
I have read a thread that reports the same issue on gdm bug tracker
and someone tried both nvidia and nouveau with no difference but I
have not done it myself.
I will try that. I have just tested that I can connect by ssh and it works fine.

Halas, I could not reproduce the freeze but I got only a small freeze
(30 sec.) and dmesg during that freeze gave:
[62645.848785] SELinux: initialized (dev fuse, type fuse), uses genfs_contexts

I see also that after trying to open lots of sessions and close them,
my 16 Gb memory is full and I had difficulties openning a new terminal
because it said "bash fork retry no child processes". I do not know if
it is linked but I read somewhere that when X freezes, it may be due
to memory leaks...
I will come back later with more info if a new crash happen.
Thanks,
Frédéric
