Re: [PLUG] How to require password on wakeup from Suspend to RAM - Kubuntu 8.10 (Intrepid)

Here's the best way I have come up with to plug the security hole.

1. Make sure xscreensaver is started and idling in the background.

2. Make sure sudo won't prompt you for a password by doing something
like sudo su - and then exiting.

3. Execute the command line: sync ; xscreensaver-command -lock ; sudo
pm-suspend (yes, I know, the sync is not needed; it's like the
rabbit's foot one might carry into a casino if one were a gambling
man, which I am not - I guess I just know too much about software to
trust computers!).

Any other suggestions to make it easier?
