Ok. Daunting as it was, I waded through the kernel update and it actually
worked. (Aside: the instructions at
https://trisquel.info/en/wiki/update-linux-libre-kernel need some
clarification; I ended up going to the jxself site directly, as suggested,
and had a much easier time). So now a uname command returns:
4.2.3-gnu.pae #1 SMP Sat Oct 3 17:02:41 UTC 2015 i686 i686 i686 GNU/Linux
Unfortunately, this did not resolve the problem.
Now, as far as the swap file suggestion goes, swapon -s returns:
Filename Type Size Used Priority
/dev/sda5 partition 786428 0 -1
I have no idea if that's 786MB or KB. Couldn't find a reference to it. free
-m returns
total used free shared buffers cached
Mem: 1000 934 65 13 13 332
-/+ buffers/cache: 589 411
Swap: 767 0 767
Which looks like 1 gig of memory, which is certainly not a lot. But could it
be the cause?
I'll wait to hear on this before I do anything else. If mem is OK then I
guess it's off to the quirks?
