Public bug reported: Binary package hint: xorg
When using multiple keyboards simultaneously, high CPU usage can be observed on the system: S %CPU %MEM TIME+ COMMAND R 94 2.2 7:26.75 Xorg R 22 2.3 0:12.56 xfwm4 S 10 0.0 0:05.02 dbus-daemon S 10 0.1 0:04.27 xfconfd R 6 0.1 0:02.34 xfce4-settings- R 2 0.1 0:00.02 top It appears Xorg is sending some kind of events to other system processes like dbus too. This slows down the system considerably. This can be easily reproduced by connecting second USB keyboard and typing on both simultaneously. Using the keyboards separately doesn't cause this problem.
