i am now looking at my laptop screen that says:
could not stat the resume device file '/dev/dm-0'
i believe the problem is related to installing TuxOnIce on this machine.
the installation failed and i removed the package.
all of this using Synaptic.
but when rebooting this machine - i found the above message.
besides reinstalling the system - which is not really necessary.
how can i fix this problem.
