Sorry, I forgot. Here's the laptop specs. Compaq Evo N610c. 1Gbyte RAM, 30Gb
HD (1GiB swap, 20GiB /home 9GiB /) Pentium 4 Mobility, ATI Radeon Mobility
7500.

If I try to suspend or hibernate from the GUI, I end up with a locked
screen. Enter the password and a message tells me that suspend or hibernate
failed and to check the help.

yes. Everything is ok after that.

I'm not familiar with uswsusp.  It is likely that there's some

That is exactly why I wrote the email in the first place ;-)

If you want to continue using s2disk, and want GNOME Power Manager's

I have learnt to live without the GUI (I have removed the power down button
from the panel) and yes, I'd rather not touch the system files as I am too
scared to make some serious damage :-) (I already suffer having to recompile
the WLAN module at every upgrade).
