I just updated, because I wanted to try if there will be any problems with 16.04 and I have the exact same problems (horizontal lines, mouse pointer not affected).
I don't even have to log in, it also occurs if I stay on the login screen long enough. For me it is also not possible to go to a console by Ctrl-Alt-F1. The only solution so far for me is to open a terminal by keyboard shortcut, entering sudo service sddm restart and the password blindly and then re-login. Afterwards everything works. The logfiles are also not very informative. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to Kubuntu PPA. https://bugs.launchpad.net/bugs/1535763 Title: Graphic problem after updating Plasma and sddm To manage notifications about this bug go to: https://bugs.launchpad.net/kubuntu-ppa/+bug/1535763/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
