Following the instructions found here I modified my /etc/default/grub with this line:

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

on a kubuntu 14.04 and a kubuntu 15.04 machines. The reason was trying to limit RAM usage of a dockerized Chrome (see here).

This caused a blank screen with only the cursor after logging in on the kubuntu 15.04 machine, as described here. I tried purging the nVidia drivers but it didn't work.

The only solution was to remove the line, remove the ~/.kde folder and restart.

Why is that? Is it possible to limit a process resources? Does this approach really conflict with Plasma 5 for some reason or I am missing something?

  • On ubuntu 16.04 with that same grub setting it makes the screen top widget bar go blank ... I am still battling on this – Scott Stensland Apr 2 '16 at 21:22
