Since an upgrade in the last 24 hours, Xorg is often using 100% of the cpu and causing major latency in Plasma. Switching kernels has had no effect. If I restart X, it goes back to normal cpu load for a few minutes, then starts using 100% of the cpu again, making the system unusable. Fully dist-upgraded system.

htop:
      Code:
1696 root 20 0 193M 48656 22524 R 100. 0.3 10:31.55 /usr/lib/xorg/Xorg -nolisten tcp -auth /var/run/sddm/{b9151dd8-cb39-4b84-8c38-57f5f2e58efe} -background none -noreset -displayfd 17 vt7

      Code:
$ dpkg -l '*xserver*' | grep ii
ii  x11-xserver-utils              7.7+7              amd64        X server utilities
ii  xserver-common                 2:1.18.2-1         all          common files used by various X servers
ii  xserver-xephyr                 2:1.18.2-1         amd64        nested X server
ii  xserver-xorg-core              2:1.18.2-1         amd64        Xorg X server - core server
ii  xserver-xorg-input-evdev       1:2.10.1-1+b1      amd64        X.Org X server -- evdev input driver
ii  xserver-xorg-input-joystick    1:1.6.2-1+b4       amd64        X.Org X server -- joystick input driver
ii  xserver-xorg-input-kbd         1:1.8.1-1+b1       amd64        X.Org X server -- keyboard input driver
ii  xserver-xorg-input-mouse       1:1.9.1-1+b1       amd64        X.Org X server -- mouse input driver

You seem to be missing all xserver-xorg-video-* packages, in particular xserver-xorg-video-intel and ideally also xserver-xorg-video-all/ xserver-xorg-input-all.

Thanks, reinstalling the xserver video packages seems to have done the trick! Not sure when I lost them.
