A few points in response to the above:
* Some distros will refuse to install unless a /swap partition is defined,
and they create one automatically if you choose 'guided partitioning'.
* If OP has only 1GB RAM, they need Trisquel-Mini, or at least a much more
lightweight desktop than GNOME. I recently tried Uruk on my Aspire One (1GB
"netbook") which uses Mate, but as soon as I opened a browser and started
watching a video on YouTube, it fell over :( Sure, I could use VLC to watch
YT videos instead, or use NoScript or whatever, but these are ugly hacks
compared to using the site like average folks do.
* Speaking of memory leaks, Firefox-based software is infamous for them. The
lagging, freezing, and crashing problems I've had running GNU/Linux of
various flavours on older machines have *always* involved a browser. Miro
(formerly Democracy Player) never works no matter how powerful a PC I've
tried it on, and I suspect the problem is memory leaks inherited from the
Mozilla code the Miro developers fork.
