openSUSE-12.2 M3 lxdm is constantly using up a high % of CPU. While the PC in
question is an old athlon-1100 w/2GB RAM and nVidia FX5200, I note on same PC
with openSUSE-11.2, 11.3 and 12.1 LXDE the same problem did not exist. Hence
this high CPU load appears to be 12.2 M3 specific. Installation was from a
build-0317 32-bit openSUSE-12.2 M3 DVD.

Reproducible: Always

Steps to Reproduce:
1.boot the pc.  CPU load is high
2.
3.
Actual Results:  
When no apps are running, lxdm in top consuses around 95 to 98% cpu load. When
other apps are running, lxdm still consumes 30% to 50% of cpu load. In
openSUSE-12.1 lxdm is consuming less than 10%.  This high cpu load impacts
video playback and makes the 12.2 install not useful for multimedia playback.

Expected Results:  
CPU load of lxdm should be less than 10% on this PC.

This could be an upstream problem as I note other distributions have reported
high CPU load with lxdm in March/April-2012.  Some users in other distributions
claimed changing from their default theme in lxde helped, but I could not find
a theme that lessened the load.
