(Get the code!)
Hello,
just a useful hint on how to get into the system: After some time of working with the quite slow Karmic version (now I know why) and a regular shutdown, the next day I couldn't run Ubuntu any more. After entering the password and some minutes of intensive working, the system returned to the login form and so on. The login form was without colours and without selection bars at the bottom. In the recovery mode I could get up to a command line and was able to see files.
This bug showed me, what's going on (thanks!). After some hesitation (I'm no expert) I have backuped the huge files "syslog", "messages" and "kern.log" and replaced them by tall or empty ones (e.g. sudo cp syslog.1 syslog ). The second start after this was completely successful.
Now the system is still slow and after some time it gives warnings about stuffed root disk --> shutdown, clean up the logs and re-run.
In my case the message about the temperature toggles between OK and NON-OK, like in a children's rhyme with the flower: she loves me, she doesn't, ....
