    While klaptopdaemon in kubuntu feisty is working properly, kpowersave doesn't. After resuming, the login mask is displayed, enlarged, rather that the suspended session.
    Ctrl-bksp restarts kdm, so that the login mask has the right resolution. My suspended session is lost however.

    In the kdm.log file, i have noticed the enclosed lines.
     
    Any ideas?
    What to look for, in the suspend2ram.log?

    Thank you for your help
