You could have a look at your .bash_history file to see whether you have issued a command that could be causing the problem. Â*If you find one, then delete it. You should be able to use your history without repeating the problematic command. Â*

That’s doesn’t sound good - or normal. You have a bad drive?

I believe an unclean shutdown was mentioned upthread?

Unclean shutdowns aren't good for your filesystem health.

repeating the problematic command.


Hmmm, It turns out that my .bash_history is filled with the garbage
characters except for the 1/2 dozen commands I have used since this
started. I cleared it by doing $ mv .bash_history .bash_history-junk.
Hopefully that's the end of it.


Thanks for the suggestion.

It's easy to make Ubuntu do a full filesystem check on the next reboot:

If an empty file called "forcefsck" exists in the root directory,
Ubuntu will do a full fsck when it next starts up. So just type:

sudo touch /forcefsck

Yes, there was an unclean shutdown. This netbook has been having
problems waking up from suspend after closing the lid. I have had
trouble diagnosing the problem. I had been just tolerating it and trying
to figure out when it was a problem and when not. But your comment makes
me think I need to dig into it again with a little more urgency.

Yes, there was an unclean shutdown. This netbook has been having problems
waking up from suspend after closing the lid. I have had trouble diagnosing
the problem. I had been just tolerating it and trying to figure out when it
was a problem and when not. But your comment makes me think I need to dig

Thanks Liam, I will give that a try.
