I tested several times without X, with X running only in backgroud (i.e. me=
=20
initiating the suspend from console) and from xdm only. Never it froze. Tha=
t=20
leads me to the conclusion that it is probably related to composite. I'm=20
using KDE 4.2.

Here is the corresponding section from Xorg.conf:

Section "Device"
  BoardName    "945 GM"
  BusID        "0:2:0"
  Driver       "intel"
  Identifier   "Device[0]"
  Option       "NoDDC"
  Option       "usevnc" "no"
  VendorName   "Intel"
  Option      "ExaNoComposite" "false"
  Option      "MigrationHeuristic" "greedy"
EndSection
