[Bug 1877871] [NEW] X windows hnags following upgrade from 18.04 to 20.04

[David Rusch]

Public bug reported:

Following an upgrade from 18.04 to 20.04 when I boot, X windows comes to
a point where I get a white background with a bunch of colored dots.
Nothing progresses from there.

I can boot successfully by pressing escape after booting, going to
advanced options, booting to 5.4.0-29 recovery mode.  When that menu
appears, I select "root".  I press Enter for maintenance.

When the root prompt appears I immediately type EXIT to return to the
menu and then RESUME followed by OK.

The system then starts the desktop properly.

I would be happy to provide boot logs and/or Xorg.0.logs if desired.  It
appears to me that there are out of memory errors occurring along with
some addressing issues.

I am on an HP EliteBook 8570w laptop 15.6 G memory.
