This question already has an answer here:
I have three non-pae (Pentium M) laptops. They are all in a good physical state and work perfectly well, so I have no reason to stop using them... that is, except for getting left behind as the later updates of Ubuntu require pae. I was advised to stick to the non-pae variant of 12.04, but that release has an Intel display driver problem that causes my systems to boot to a blank screen. Reverting back to 10.04.4 LTS has a similar Intel display instability.
When I have asked this question elsewhere I have been advised to throw away my hardware and buy new. I'm reluctant to junk perfectly good machines, and I don't have the finances to replace them.
So.. advice please on where to go with this situation.
