Comment 41 for bug 1615734

Hm, I am on 18.04 on Thinkpad 530 and Mini Dock Plus Series 3 with three monitors and I have a very mild version of this problem. Only after suspend, the two monitors that are connected via the dock flicker (either show screen corruption or repeatedly blank in and blank out). The one connected to laptop's miniDP port works fine.

However, I only need to issue xset dpms force standby to make them turn off and then move a mouse to make them turn on again. Another alternative is pressing alt+ctrl+F6 to go to tty6 and then alt+ctrl+F7 to go back to graphical interface. Still inconvenient though.
