That may be the key of your problem: no place, the system can't create
logs. How is your disk partitioned? "A la Windows", with one big partition
and everything in it?

That is my suspicion. The disk was partitioned by Dell at the factory, and came
with Ubuntu installed. There is a 3GB swap partition and a 117GB Ubuntu
partition.

How does one get permission to do file deletes while using a USB stick?


When I try to log in, there is a notice

"INSTALL PROBLEM

The comfiguration of dedfaults for Gnome Power Management have not been
installled properly

Please contact your computer administrator."

Is there some way to get at the hard drive and delete a couple files?

I'm not sure to understand "I can use the computer a USB stick". Anyway,
you should find a way to boot from a live system (USB stick or live CD),
then mount your disk/partition and, as root, you should ne able to delete
files.

I can boot from the USB stick. But I don't have permissions to do anything
useful, like deleting files.

I did find how to boot into recovery mode. I then did
"rm BigRedundantDirectory" which didn't help. The directory is gone, but no
space was freed up.

Now that I am in recovery mode, is there a way to force Ubuntu to validate the
disk?

You can also check the size of the directories, most probably /home/<your
user>. If one directory is _very_ big, then the file to delete is there.

If a program get's stuck in an error loop, it may fill up your disk space
with a huge error log. That's why /home should _always_ be on a separate
partition, so if your home directory get's full, you can still log in as
root to clear space (that's where Ubuntu's policy bites back as you'll
have to do this at the command line...)

I looked, there are no 8GB (which was the old free space size) files.

Hope that helps

Thierry

Other than the 0 bytes, the gnome power manager error msg sounds exactly
like the problem that seanh was having in the "Can't login into Gnome
after updates yersterday (10.04" [1]. I wonder if this is becoming a trend.
