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

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.
