Does the problem also occur in Gnome Shell, or only in MATE?

Title:
  HID inputs (mouse buttons and keyboard) stop responding when plug in
  DP monitor

Status in ubuntu-mate:
  New
Status in mate-common package in Ubuntu:
  New
Status in xorg-server package in Ubuntu:
  Incomplete

Bug description:
  Ever since upgrading to 18.10 plugging in external monitors has been
  buggy.

  Device Lenovo T460s. Ubuntu-Mate 18.10.

  Plugging in External monitor using mini-display port causes keyboard to
be unresponsive. Mouse buttons as well. though can still move mouse on
screen. Plugging in and out using arndr sometimes resolves this.
Notwithstanding, no smooth transition to multimonitor mode.
