Yep, first thing to do.
And keep on digging on the videocard driver side if you still have

Scilab tends to be a good way to detect buggy video drivers!
Getting a cheap videocard with decent drivers might be the easiest
way to solve your problem.
You might try to ask other Linux users what card they have and
whether they get graphics related crashes.
