Ubuntu 22.04LTS GDM3 Troubleshooting (Not loading desktop, only showing"Unlock Login Keyring"

mr flag

After messing around on the Login screen, I found the little cogwheel that lets you change desktop environments. I clicked Kodi, logged in, and it worked fine, so then I decided to try Openbox and TWM and none of those launched, so I went to bed and called it a night. When i tried to log into Wayland again this morning I was greeted with a black screen and only "Unlock Login Keyring", and once I unlock it the screen freezes up. I'm pretty sure that using Openbox broke my GDM install since I don't think I had the dependencies, I'm not even sure what it is to be honest, any help will be appreciated and I will update with whatever information is required.

Additional info 1: When I do CTRL+ALT+f1 it opens the login screen, but I cannot change the environment and when I log in it takes me back to the same screen- I am able to open a new session on TTY3 though. and the cogwheel is missing.

Made a new User account in TTY and was able to load into wayland. Next step would be to compare config files?

Accessed the xsessions files and these are the contents of the options i selected.

For ubuntu.desktop:

Name=Ubuntu
Comment=This session logs you into Ubuntu
Exec=env GNOME_SHELL_SESSION_MODE=ubuntu /usr/bin/gnome-session --session=ubuntu
TryExec=/usr/bin/gnome-shell
Type=Application
DesktopNames=ubuntu:GNOME
X-GDM-SessionRegisters=true
X-Ubuntu-Gettext-Domain=gnome-session-42

For openbox.desktop

Name=Openbox
Comment=Log in using the Openbox window manager (without a session manager)
Exec=/usr/bin/openbox-session
TryExec=/usr/bin/openbox-session
Icon=openbox
Type=Application

For twm.desktop

Found the answer! Ubuntu 20-04 won't boot up after modifying /etc/gdm3/custom.conf file - AskUbuntu

my etc/gdm3/custom.conf looked like this:

# GDM configuration storage
#
# See /usr/share/gdm/gdm.schemas for a list of available options.

[daemon]
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=true

# Enabling automatic login
#  AutomaticLoginEnable = true
#  AutomaticLogin = user1

# Enabling timed login
#  TimedLoginEnable = true
#  TimedLogin = user1
#  TimedLoginDelay = 10

#AutomaticLoginEnable=True
AutomaticLogin=crith

Clearly the syntax is wrong, but commenting WaylandEnable=true and AutomaticLoginEnable gave me the cogwheel back, from where I was able to select Ubuntu.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
