Forgot to mention in report, I used Kubuntu backports ppa to update KDE on my installation.
I changed 'start' rule in /etc/init/kdm.conf to: start on ((filesystem and runlevel [!06] and started dbus and plymouth-ready and (drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1 or stopped udev-fallback-graphics)) or runlevel PREVLEVEL=S) This did'nt changed anything, plymouthd is still eating 5% of CPU on background. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1240376 Title: Plymouthd constantly using 5% of CPU time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kde-workspace/+bug/1240376/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
