Thanks Brendan. Next please try selecting 'Ubuntu on Wayland' from the
login screen. Does that avoid the bug?

Bug description:
  New bug for me. Issue was fine till last week. I think this may be
  related to the following as it started happening shortly thereafter.

  I have XPS13 with second monitor, all working fine till I lock screen
  or suspend. Then my second monitor will not 'resume'. I.e. stays off.

  This behaviour started after (or shortly after) playing a wine game
  using Lutris to launch. Shutting game down and almost immediately
  hitting suspend on the laptop. Was rushing out.

  It's a wild shot in the dark but I think something got messed up / not
  saved correctly in this process.

  To get it working I need to unplug monitor (using USB-C > HDMI) >
  suspend > plug in monitor > resume and sometimes still need to open
  display settings before it 'kicks in'. Damn annoying. Hope someone can
  help :)
