I did a clean install of 24.04.1 . Things were fine for a few days. Then a dialog box came up saying something to the effect that there were a few additions to be installed. So I triggered the install. When it rebooted, it came up in raw terminal display (this seems to be a bug in the ubuntu additions install) for tty1. To get the GUI back I did: XDG_SESSION_TYPE=wayland dbus-run-session gnome-session This resulted in a very odd partial GUI, so I ended up doing:

    sudo dpkg-reconfigure gdm3
    sudo service gdm3 start

and reboot. Then it came up in the standard ubuntu GUI and applications I tried seemed to work, everything seemed good, except for firefox. On trying to launch it in the terminal, it gives:

$ firefox
Gtk-Message: Not loading module "atk-bridge": The functionality is 
provided by GTK natively. Please try to not load it.
Error: cannot open display: :0

It looks like in my attempt to get a GUI back, I messed up something with the display. Note that:

$ echo $XDG_SESSION_TYPE
wayland

and this problem occurs whether starting the snap or the deb version of firefox. Any help would be appreciated.

There was a problem with the ubuntu 24.04.1 install that others are mentioning. Specifically this question: Major software missing after 24.04.1 LTS upgrade The solution was in it, to run: sudo apt install --reinstall ubuntu-desktop^ and then reboot. Firefox then worked properly, and seemingly, so did everything else and the GUI looked ok.
