This sounds like a graphics/video driver type bug or instability. It could
also be hardware (heat?) related. A modern operating system never allows an
end user application to crash the entire system, so when that happens it
usually points to a driver bug or a hardware problem.
Can you type Ctrl-Alt-F1 to get to a text login screen?
Otherwise can you ssh in from another machine via the network?
In the old days we used to set up a dumb serial terminal so we could still
get in when X went bonkers.
