I recently upgraded from 11.04 to 11.10, but I get "Not enough free swap" error when trying to put my laptop to hibernation.
I have 2GB of physical memory and 3GB of swap. Besides, the hibernate worked fine in 11.04.
memoinfo is here:
SwapCached: 0 kB SwapTotal: 4028604 kB SwapFree: 4028604 kB
So what might be the problem?
