I don't know. I don't use this machine often, except remotely
(via ssh). But problems with the nouveau driver were common
(and a crash could occur in the nouveau driver even when using
the machine remotely only), and I haven't seen any issue recently,
even the last few times I logged in physically.

I sometimes log in physically, but go away without logging out first
(there are sometimes a good reason, e.g. if some computation program
hasn't finished yet and I had not started it in "screen"). I can
later log in via ssh and kill the X session.
