Bug description:
Ubuntu Version 18.04 LTS
gdm3:
Installed: 3.28.0-0ubuntu1 500
Package name: /etc/gdm3
Whenever I boot Ubuntu following installation from the official
install ISO, the boot screen appears, but the login manager appears as
static, scrambled graphics, making me unable to login without opening
the VT and installing lightdm and switching to that login manager.
Expected Results:
Login manager appears with login field, background, and menu while I am able
to find, click, and enter information into the login text fields.
Actual Results:
Scrambled noise appeared on my screen and I am unable to leave without
force-shutting down my Gateway PC, or opening a VT and installing lightdm,
rebooting afterwards.
