Output of dmesg
Operating System: Arch Linux
KDE Plasma Version: 5.14.5
Qt Version: 5.12.1
KDE Frameworks Version: 5.54.0
Kernel Version: 4.20.6-arch1-1-ARCH
Graphics Card: NVIDIA GeForce GT 650M
Plasma locks up after splash screen, and it is sometimes (but not always)
possible to switch to tty2 and kill the session using loginctl. The magic SysRq
keys Alt+SysRq+REISUB and Alt+SysRq+REISUO always work though.
This seems to be a problem related to acceleration because adding the
'nouveau.noaccel=1' kernel parameter solves the problem, but disables some
desktop effects as well.
