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 multi-monitor mode.
EDIT: 2018-11-22 // The problems are not observed when using HDMI instead of
mini display-port. Moreover, if one can regain control of HID devices when mini
DP plugged in, the resolution of the monitor plugged in is completely wrong.
