I’m a new opensuse user who just installed the latest 13.1 and I’m very satisfied with a new distro However I have one problem, every x (random) restarts/startups my desktop effects become disabled when I login to the system and then I have to enable it manually (alt shift f12). Few spec. information: open suse 13.1x64, fully updated with nvidia blob installed (through 1 click). Apart from this little annoying problem everything works as expected (movies, games,steam etc)
I tried to remove .kde but I didn’t help. I cant find anything useful in logs. After the issue occurred xsession_errors showed some kde specific data but I’m not sure if it contains anything useful SUSE Paste
The pertinent directory is ~/.kde4 note you need to be logged as root at the command line to do it right since that Directory has active files when you are logged as the user
It seems strange that sometimes it works and some times not. Maybe run smartctrl to check the disk for errors
All tests passed. When the issue reoccurs I’m able to start kwin from a console:

It seems you are using the nvidia driver without triple buffering
You must export __GL_YIELD="USLEEP" to prevent large CPU overhead on synced swaps
Preferably, enable the TripleBuffer Option in the xorg.conf Device
For this reason, the tearing prevention has been disabled.
See https://bugs.kde.org/show_bug.cgi?id=322060
Is there any way to log kde activity during a logon process?
Removing the entire ~/.kde4 folder is a rigorous measure. Re. graphical issues most of the time removal of the plasm* files in ~/.kde4/share/config whilst not logged in is enough.
IMHO you’d better have a look at the rendering by KDE: Systemsettings - Desktop effects - Advanced. Which are the settings now?
Compositing type: opengl 3.1 (same effect on 2.1)
QT graphics system: raster
Keep windows thumbnails: only for shown windows
Scale method: accurate
Suspend desktop effects for fullscren windows - checked
Vsync: automatic
Enable color correction - unchecked
This randomnes is weird and lack of errors when I start kwin manually :\ Anyway I’m glad for help.
