Created attachment 105519 [details] ksmserver-logout-greeter crash log Apologies if this is miscategorized.. the tracker describes this as "The screen locker framework consisting of the KScreenLocker library and the greeter process.". I'm getting both and I assume these issues are related in some way. --- Not sure which update caused this, but I updated to day (last time was about 1 week ago) and kscreenlocker and ksmserver-logout-greeter started crashing with 100% reproduciblity. Any screen lock causes this warning that the screen locker is broken: https://i.imgur.com/LVKKdml.jpg Any time I try to reboot, ksmserver-logout-greeter crashes. Crash log attached. Neon 5.9.5 Frameworks 5.33.0 Kernel 4.4.0-77-generic Let me know if any more useful info should be provided
Your OpenGL driver is broken.
Seems you were right, thanks. Updated Nvidia driver fixed it I had just installed system updates and greeter/screen lock suddenly started crashing. It is fixed now, feel free to close
Driver bug.
I wanted to chime back in about this. I decided for no particular reason that I wanted to reformat my system and start a clean install of Neon. I ran into this issue again after a fresh install.. so it may be worth looking into. I installed Neon (neon-useredition-20170518-1018-amd64.iso), started it up for the first time with nomodeset in Grub (black screen on boot otherwise), and the first thing I did was new install Nvidia proprietary drivers 378.13 from the ppa (ppa:graphics-drivers/ppa). After install, I went to reboot from the launcher and ksmserver-logout-greeter immediately crashed. I had to reboot from the terminal. It seems that installing a driver update changes something that greeter doesn't expect to change, so it spazzes out. But then it's fine after rebooting (presumably when greeter reinitializes with the new changes). I think there is still some kind of exception handling that needs to be put into place to catch this. System info: ASRock H270M-ITX/ac, i7-6700k, GTX 970 Neon installed with encrypted home directory.
Resetting as it is a driver bug.
