Disable it by booting with drm_kms_helper.poll=0 on your kernel command line in grub. Also make sure kde is not polling the monitors itself in the background at regular intervals. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
