Closing and reopening the laptop lid leads to a problem with kded4 on lucid amd64. kded4 gets defunct and therefore a new kded4 is respawn all the time. So after a while there are lots of kded4 with state defunct. A ps waux | grep kded4 gives lots of lines like
<user> 26217 0.0 0.0 0 0 ? Z 13:42 0:00 [kded4] <defunct>
after a killall -9 kded4 and manually restarting kded4 the system behaves normal again.
