kpowersave suspend-to-ram does not work

[pol]

<posted & mailed>


While klaptopdaemon in kubuntu feisty does work properly, kpowersave
doesn't. After resuming, the login mask is displayed, enlarged, rather that
the suspended session.  
Ctrl-Alt-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 file? 
  
 Thank you for your help
