I hope i have some that are helpful. :-) > - In total I want to increase my swap to 1024mb so that I can use > hibernating on my laptop.

I think there has to be room for a little bit of state information, but i can't remember where i heard that. > What is your experience with hibernating?

Your situation may be different, but i found it too slow to be feasible - it was quicker to reboot than to hibernate. I use suspend all the time and it works OK. A couple of times i've had problems, and if that's the case i just force a reboot. > - By now my root dir is 5.2 GB big and now after a year filled to 3.6GB.

I can't think why anyone would want separate partitions for anything except /home, especially on a laptop where space is more likely to be at a premium. My laptop has 2 partitions: /boot, and encrypted LVM. In the encrypted LVM are only root and swap, nothing else. > - Although I want to do a clean install to get rid of the debris of my > initial "getting familiar with ubuntu" period I > would like to keep as many settings as possible.

If anything, all of /home would be what i would keep. > Especially with Firefox I've read that 'starting over' can increase stability > quite a bit.

After years of reading Bruce Schneier, i don't have much confidence in fingerprint readers and the like, and even encrypted hard disks have been cracked through a memory scanning technique now: http://www.schneier.com/blog/archives/2008/02/cold_boot_attac.html Paul
