Public bug reported: I upgraded to Plasma 5 using both the ppa:kubuntu-ppa/next and the ppa :kubuntu-ppa/next and a second time using ppa:kubuntu-ppa/next- backports.
After login everthing looks and works great. However about 3 minutes after either using or not using the system, it freezes. I can move the mouse, but can't click anything, nor use any keyboard shortcuts like Alt+F2. I've checked /var/log/syslog and xorg logs which don't show anything. The Bug is similar to the following bug, however, Alt+Tab or any other key combination does not unfreeze the desktop: https://bugs.launchpad.net/kubuntu-ppa/+bug/1384512 My system is: Clevo Laptop Intel i7 4th Gen Processor Intel(R) Core(TM) i7-4800MQ CPU @ 2.70GHz Nvidia Graphics (with Optimus) GeForce GTX 850 Kubuntu 14.10 Any assistance would be greatly appreciated. Included advice on what log files to check. ** Affects: kubuntu-ppa Importance: Undecided Status: New -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to Kubuntu PPA. https://bugs.launchpad.net/bugs/1422185 Title: Plasma 5 freezes after 3 mins To manage notifications about this bug go to: https://bugs.launchpad.net/kubuntu-ppa/+bug/1422185/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
