Cannot log in to plasma desktop after crash, startplasma-x11 takes all the RAM

I will try it, thanks.
But first I’ll try your advice with the configs from another topic.

Plasma desktop won't properly start anymore - high CPU load

I still say try the ‘configuration related’ steps: (I will augment them this time so that everything is backed up) cd ~/.config for j in plasma*; do mv -- "$j" "${j%}.bak"; done mv Trolltech.conf Trolltech.conf.bak kbuildsycoca5 --noincremental cd ~ Reboot. See if its ‘fixed’ … if so … start moving your configurations back one-by-one … find the culprit.

Thanks @Takakage for pointing to that one.
