I just encountered the bug again. When I turned on the monitor the login
screen is at 1024x768 and the system log shows it is using Wayland:

Jun 15 14:03:49 nine gnome-shell[1225]: Running GNOME Shell (using
mutter 42.1) as a Wayland display server

Although the monitor was plugged in when the system booted, the kernel
failed to get a working connection:

Jun 15 14:03:50 nine kernel: i915 0000:00:02.0: [drm] *ERROR* Link
Training Unsuccessful

That's _after_ the login screen had started. So the bug is occurring
when the kernel can detect a monitor (hence bug 1919400 doesn't happen)
but can't establish a reliable display signal.

For me, the fix was just to log in as usual. Then the correct screen
resolution is detected and used.

If the problem persists for you after logging in then it's a sign you
probably need to replug or replace the monitor data cable. I don't see
any real bug here unless it's the kernel failing to train when it
shouldn't fail.

Title:
  [i915] Desktop resolution was set incorrectly (1024x768) until I
  booted up the PC AFTER turning on the monitor

Status in linux package in Ubuntu:
  Opinion

Bug description:
  Whenever I boot up my PC, I turn on the monitor as well. When this
  happens, the Intel Mesa graphics loads, and my screen ends up being
  small with large pixelated icons. The resolution was capped at
  1024x768. Only after I reboot my PC multiple times without changing
  the display settings did the resolution increase to 1680x1050, the
  correct resolution.
