[xubuntu-users] Seeking help: computer wakes to dark screen

[JMZ]

Peter's tips on swap reminds me of another point.  2GB RAM is a bit 
small, even for xubuntu.  Swap isn't really the same as RAM memory. 
Generally speaking, it's a hard disk partition which emulates RAM memory 
when the RAM is maxed out.  It's slow, and not as reliable as RAM memory.

I've never owned any Mac, but the new Macs are very similar to PC's 
under the hood.  I'd get another 2GB of memory at least just to make 
sure that you aren't relying on swap to keep your system running. RAM is 
really cheap now compared to, say, 23 years ago ($20, $30?). I remember 
buying _2 MB_ of PC RAM for $200 ($325 today) in the early 1990s!
