I need Gnome as my display manager. So this is a strange case.

I used to be a windows user but then I switched to Ubuntu and was using Gnome as usual. Everything was fine but one day I installed an app called Texts.com. It was an appImage and It run well the first time but then suddenly my system crashed.

I thought it was a normal error. So when I restarted, it went on the usual screen asking my username and then my password. As soon as I entered the password, the screen crashed and I was shown the following screen.

The error I am getting.

After this I tried to switch to Openbox and got a plain black screen. Then after much struggle, I got to open the terminal at the login screen, entered the password and installed lxqt / Lubuntu using terminal only, and much to my surprise, the Lubuntu is working fine.

Now I get 4 options in my display manager - openbox (not working) , lxqt desktop (working), GNOME Classic (not working) , Lubuntu (working)

But I don't want to use Lubuntu, and want to go back to GNOME or the normal Ubuntu I used to have.

    GNOME is a desktop and not a display manager, the GNOME DM is actually gdm3. Lubuntu uses the LXQt desktop, sddm as the DM and openbox as the WM. I login to an openbox session may not give anything but a black screen; that's expected UNLESS you've setup something to give you background, menus etc (openbox can use obmenu as the obmenu if setup correctly). Don't forget openbox is only a window manager (WM) & not a full featured UI, unless you configure it as such by adding features/functions (eg. Lubuntu/LXQt uses pcmanfmq-qt to display a background on the system)

    You are mixing up ideas/concepts and what applications actually do, thus you problem is probably your expectations are likely incorrect. A openbox session for example by default is simple (black screen with nothing but pointer - ie. it's a minimalist environment and extremely lean; it can't handle even a wallpaper/background by default). Openbox is after all a window manager; it handles the borders around windows, positions etc... and doesn't handle desktop/displays as those are handled by other apps.

    To go back to what you had, I'd explore what changes you have actually made, and plan a route that will reverse those changes. If you're like me & use terminal, your bash history (history) should remind you what changes you made (ie. I'd expect to see what files/configs I edited there, what backups of pre-changed-files I made etc), for package changes you can also look at apt logs (/var/log/apt/history.log); ie. it'll show what you installed/removed etc. I don't know what you did, and your description is confusing, so I'm not sure what to advise. I expect you made mistakes in approach

    If you right-click on the black background of an Openbox session, do you see the OBMENU, which is rather limited & basic (but can be expanded, but you have to do that yourself; as openbox by design is a very lean (ie. limited) environment so as to remain 'light')... If you do, then openbox is working correctly too (though it could be working & you just don't have obmenu installed/setup to run; as I don't know what exactly you did)

    FYI: I booted up a pretty clean (ie. unchanged) Lubuntu [23.10] system and logged in with a openbox session. The end result is two black screens and a pointer, ie. an openbox session. On this ~default setup, I do get a OBMENU on right-click of the black background, that gives me Shortcuts/FM/Term/Inter/Apps/Acce/Int/Off/Mult/Sys/Sys/Logout options. I'd try your system and I suspect you'll get the same. ie. openbox is doing what it's supposed to. Being a window manager, it handles the windows, giving them borders, buttons, allowing resize or movement etc. Openbox can be used with many DEs
