Bug ID: 356828 Summary: kscreenlocker_g crashes with SIGABRT, continually dumps core Product: kscreenlocker Version: unspecified Platform: openSUSE RPMs OS: Linux Status: UNCONFIRMED Severity: crash Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: robert.munte...@gmail.com CC: bhus...@gmail.com, mgraess...@kde.org Using plasma5-workspace-5.4.3-1.1.x86_64 on openSUSE Tumbleweed x86_64. When trying to lock the screen the image freezes - no lock screen appears and I am only able to move the mouse but not input anything. Switching to another VT and running 'top' shows that I have 7-8 coredumpctl processes running at the same time. I'm running a W541 Lenovo Laptop using the Intel video card only - neither nouveau nor the nvidia proprietary drivers are installed. Reproducible: Always Steps to Reproduce: Try to lock the screen. Here's a core dump summary from coredumpctl PID: 29049 (kscreenlocker_g) UID: 1000 (robert) GID: 100 (users) Signal: 6 (ABRT) Timestamp: Thu 2015-12-17 14:21:36 EET (22min ago) Command Line: /usr/lib64/libexec/kscreenlocker_greet --immediateLock --ksldfd 52 Executable: /usr/lib64/libexec/kscreenlocker_greet Control Group: /user.slice/user-1000.slice/session-13.scope Unit: session-13.scope Slice: user-1000.slice Session: 13 Owner UID: 1000 (robert) Boot ID: fa49e85f2ebf4f31b00f5e04300e9e6d Machine ID: 87f0790206514af7a87d17a290547703 Hostname: rombert.corp.adobe.com Coredump: /var/lib/systemd/coredump/core.kscreenlocker_g.1000.fa49e85f2ebf4f31b00f5e04300e9e6d.29049.1450354896000000.xz Message: Process 29049 (kscreenlocker_g) of user 1000 dumped core.
