Right, but as I said, if you only have a / (root) partition and a swap
partition, there is no adjusting to do, beyond deleting stuff
elsewhere, And be that as it may, the stuff in /var does nothing to
make your computer run faster... as they say, it holds state files,
caches, spools, logs and stuff like that. And yes, I supposed if you
run out of space on a /var partition or your hard disk itself, you'll
definitely see a performance and stability problem...
BUT, if you don't know whether or not you have a separate /var
partition, you probably don't. The default partitioning scheme for
Ubuntu (for a while now) is a / partition and a swap partition. To
double check this, you can run the 'mount' command and see what's
if you see an entry in the output that says /var, then you have a var
partition, otherwise, /var is part of the / partition, thus, if you
fill up your root FS, things won't be able to write to /var and thus,

Roughly 2GB swap space there... you're only using about 4 MB, and
that's probably about right for a system that just started or hasn't
been running long (or isn't loaded).

That's a lot of stuff to be running with only 800MB of RAM... Firefox
alone, especially with a few plugins, can easily start chewing up 200
- 400 MB after it's run for a while...

my single firefox instance is currently using up more RAM than your
system has in total... it's been running for about 24 hours straight
now and has about 15 open tabs, using some Java, and it's also
probably got some memory still used up with old Flash data from
watching some videos...
OpenOffice can also use up a good bit of RAM, as can Thunderbird.
Putty and Gedit, AFAIK are fairly lightweight, no idea on NoteTab, but
wine is also a huge resource consumer, anything that handles image
editing (it as to keep the program and the full decompressed image in
memory as well as use more memory when it's doing things edity like
scaling, masking, coloring, filtering, etc...)
Seriously, if you're running all that stuff concurrently, you need to
invest in a bigger machine. heh... but I know what you mean, I often
have many many things open. Right now, I have XChat, Firefox, 8
xterms, a couple self organizing tools, calculator, Evolution, gtodo,
gimp, transmission, and totem...

You still haven't actually said WHAT you're seeing, beyond vague
references to "others have seen" something... What specific mouse
failures? What specific boot failures?
Those, though possibly two completely separate issues...

Not yet, theres a little used, but that could be just normal
overhead... when you start seeing more than 10 - 15% swap used,
you're using it... which in your case, the Used column for Swap should
show 200MB or more in use... (and that's really conservative, in
reality more than maybe 20MB could be considered really in use... it

Yeah, I'd be interested in that too, just for kicks :-)

With only 1GB of ram, you probably don't need a 64bit OS. I have 4
with the possibility of 8GB if I ever buy the big DIMMs, so I am
running the 64bit... but my AthlonXP and netbook both run 32bit just

I'm not intimately familiar with the Vostros, but I am pretty sure you
have 1GB of ram and roughly 128 or so shared for Video... if at all
possible, if you're running that much stuff, you need a bigger system,
and if you can't do that, you need to max the ram in that machine...
As for stability issues, as I said, what SPECIFICALLY are you seeing
WRT boot and mouse issues?
If you're running that much stuff and your mouse issue is that the
screen/UI just completely freezes, it's a good bet that it's because
you're just running way too much stuff for the resources you have. As
far as booting, as I said, that's a different issue alltogether, and
probably needs it's own thread.
