I have not so big, but anoying problem - system won’t restart when using standard methods (ctrl+alt+del -> restart, or leave -> restart). Screen goes black and stays like that until I perform hard reset. When I log out and then restart it, it works. Commands “reboot” and “shutdown -r now” also work.
As I said, it is more anoying, than a big problem, but I would just like to know what causes this.
I am using openSUSE 13.1 KDE with kernel 3.11.10-11-desktop
Sounds similar to the hibernate bug that I posted a few days ago and is now in Bugzilla. Can you try hibernate from the Application Launcher -> leave. If that also locks up then it may be the same issue and a developer has been assigned to the problem I reported.
