What should I do when Ubuntu freezes?
My Ubuntu 11.04 installation keeps randomly freezing. I can't really find a pattern in when it happens.
First the cursor starts lagging behind for about 5 seconds, and then suddenly the whole screen freezes. Things like CTRL+ALT+F1 also do not work at those times.
This is getting really annoying, and on the Ubuntu IRC no'one seems to be getting any further than I do.
This is my dmesg: http://paste.ubuntu.com/653077/
It froze again about 5 or 10 minutes ago.
I am using the nvidia-173 drivers because Unity won't work using the nvidia-current ones.
Edit
I seem to have solved most of these freezes myself by enlargin my swap partition. I thought I had a 1GiB one... turned out I made a mistake and had actually made it 1MiB xD I now resized it to 4GiB. But my computer still freezes regularly, and this is really pissing me off now... This is a more recent dmesg: http://paste.ubuntu.com/664464/. It froze again a few minutes ago.
