On any of our Dell workstations(E5400, 4gb RAM) when trying to lock the screen it will freeze up the system. I tried it from the command line which results in a seg fault. My newer laptop (Lenovo t430u) will actually work, but takes a while even on this high end system. The strace of process shows a inoridinate amount of access calls to files that are non exisistent, and according to kde is deprecated. (Such as the case when accessing directories like /home/user/.kde/share/locale/en_US/LC_SCRIPTS/kdelibs4/kdelibs4.js. If that has anything to do with it I don't know, but what eventually happens is the process segfaults, and will continously respawn in a never ending cycle. This brings the system to a halt and not even SSH'ing in to killing the process will do anything. I have about 500 of these in production so this a block for me to rollout KDE. Reproducible: Always Steps to Reproduce: 1. Start KDE 2. Hit CTRL-ALT-L or Run process from CLI 3. Box Freezes/Seg faults Actual Results: Process segfaults restarts and KDE freezes although you can get in with SSH. Expected Results: Screen Locks The image is via NFS as well as the Home directory is a NFS mount. Workstations are Vostro 230, E5400 4GB RAM.
Created attachment 81202 [details] Strace of kscreenlocker_greet exact command "strace -vvvv /usr/libexec/kde4/kscreenlocker_greet --nocrashhandler"
With the lack of help. I had to replace it with xscreensaver.
Sorry for the delay in answering. We actually need the back trace of the crashing process in order to investigate. But I highly suspect nfs mounts to be the cause for the problems here.
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years and I will be closing this bug. Please re-test and file a new bug with kscreenlocker if the issue persists.
