http://bugzilla.opensuse.org/show_bug.cgi?id=957061 Bug ID: 957061 Summary: plasma5 cannot unlock locked screen Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.1 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: kde-maintainers@suse.de Reporter: nico.kruber@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- after installing the NVidia binary driver (version 358.16 "the hard way" or 352.55 from the repository), I am unable to unlock my plasma5 session once the screen locker steps in. This is not due to #931296 since kcheckpass works for me, also after submitting my password, a black screen is shown for about a second and then I'm back at the screen locker. I dug up several bug reports, but most of them are related to the kcheckpass and pam problem. This is not as the backtrace below shows. It seems that the Arch guys have been affected and they solved it with new Intel microcodes (https://bbs.archlinux.org/viewtopic.php?id=196536), however, that was still a Haswell system while mine is Skylake. I tried with the supplied 4.1.12 Kernel as well as 4.3.0 from Kernel:Stable. I'll post an update with the new microcodes from the Base_System repo (if I get them to be used) related: https://bugs.kde.org/show_bug.cgi?id=346938 https://bugs.kde.org/show_bug.cgi?id=346525 FYI (although I don't think, this is related): I do have a Asus Strix GTX 970 ===================================== plasma5-workspace-debuginfo-5.4.3-122.1.x86_64 (gdb) run Starting program: /usr/lib64/libexec/kscreenlocker_greet [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".
