Can you ctrl-alt-F1 and open up a pty? Log in there if you can and
"service lightdm restart" it. What are you "doing" when that occurs?
Games, graphics, do you have compiz enabled?
I second this, I've been through a gambit of x issues, though never
quite seen that where x will drop out like that. Using ubuntu, sounds
like lightdm issues, not a hard drive or pulseaudio (though it has its
own issues). I did have a crap zotac nv8600 card for a while that would
do funky things until it just literally lost its mind and started
throwing pixels on boot, that's almost always hardware or driver related.
Though, I can tell you when my ati graphics get cranky from games after
a while, I can almost put money on throwing one of my ssd's out of a
mirror set like clockwork after using gl-driven things (games, some
apps, compiz being enabled especially) for a few weeks. Invariably I
have to reboot, initialize the disk, and rebuild it and it's fine until
it gets cranky. Weird part is, it'll only do it on my crypto/lvm-pv, not
on my first 256mb /boot partition that almost never gets read.
I'd love to know if anyone's seen that, or better yet know how to fix
it. I worked pretty hard to figure out how to align sectors on the
ssd's, but still seems cranky with the stupid ati drivers... Never had
that with nvidia, but been on ati since things have gone to ssd.
