Hi Phil,

Thanks for the advice, unfortunately, that lap *%& seems to freeze
after waking up from suspend. Switching the screens does not help, i
cannot connect to it using ssh or something else.

In fact, it is a DELL (just to please...) Latitude C540 using a ATI
Radeon Mobility 7500 (yeeeeeeeeeees, and compiz isnt working on it
either ;))

something else i can try?

Roger
