If it's software at all then this would be a kernel bug. But I suspect
the issue is more likely hardware since 1920x1080 @60Hz is pushing the
limits of analog VGA. Anything less than a perfect cable with perfect
connections and I'd expect display glitches like this.

Personally I'd recommend adding a graphics card to the machine so you
can use HDMI on both monitors. But you might also want to try 30Hz to
see if it makes the display more stable. We can also keep this open as a
kernel bug just in case it is.

Title:
  Analog VGA goes black on resume

Status in linux package in Ubuntu:
  New

Bug description:
  Starting a few weeks ago after applying regular maintenance to 22.04.3
  LTS one of my two displays, an LG 22MP47HQ-P connected to my tower by
  a D-Sub cable, blinked multiple times immediately on resume from
  suspend.  My second display which is connected using HDMI works
  normally. This, of course, was merely a mild annoyance because after a
  few seconds it stopped. However in the past week that same display
  flashes on, and then goes black. I power the display off and back on
  and again it flashes on for a fraction of a second and then goes
  black. After several power cycles of the display it stays on, so again
  this is only a mild annoyance. Is this a known issue with a recent
  update?

  Specifically this is after a deep suspend, one where on unlock you
  need to press a key to get the login prompt.

  I tried updating to 23.10 but the problem is there as well.

  This bug tool does not permit reporting a problem against Wayland.
