I guess thats it. I have 2x 4GB swap, running many progs+virtualbox
continuously. In the morning i wait 1-5 minutes till i get a passwd prompt.
Today i went to tty1 and called top, no strange process there.

The question is: cannt i get it faster by default setting xlock to higher
priority?

thx...
