Hello Christian,

interesting news!

I've made some tests with openSUSE 13.2 KDE live by using it as live medium
(boot from SD-card) as well as installed it on a free partition.

Here are the results:
- 64-bit version is not affected. *Only* for 32-bit this issue is valid.
- When desktop effects are enabled - no issue.
- When desktop effects are disabled - suspend/resume triggers my issue.

Easiest way to reproduce e.g. on your RS880 machine:
1. Grab a copy of opensuse 13.2 kde live 32-bit e.g. from

2. Burn it on DVD or copy to SD or USB stick (I'm using "SUSE Studio
Imagewriter" for that. "dd" may also work)

3. After booting, press shift-alt-F12 to disable desktop effects.
4. suspend to RAM and resume.
=> last line should be black on screen
(5. pressing shift-alt-F12 again and screen will freeze except for the mouse)
(6. suspend to RAM and resume and everything will be OK again.)
