Same problem. Also there was often freezing in Xfce, mostly when
switching between windows, SysRc+r help unfreeze.
Setting init_on_alloc=0 help with this (suspend and freezing).
But now, if second monitor connected (VGA or HDMI), after login Xfce
freeze. Maybe it's different issue, something about xfce or randr.
