I have no .xsession or .xsessionrc file, where the hell do I set the environment, and what do I set it to? tint2 starts fine, btw,

Re: Xfce4-panel/lxpanel won't start in bullseye Openbox session

The session manager it wants is xfce4-session, but I think that's a warning that can be ignored.

But why those two don't start I don't know. I have to go now, or I'd try it on my VM.

That package died with buster, it's not in bullseye and it's not in sid except for one version for an obscure architecture.

I saw this in the screenshot thread.

Is cinnamon always the session? You may be getting some conflict. Can you run gnome-panel - or whatever cinnamon uses?

Create a new user and see if you can log in with openbox and xfce4-panel, or lxpanel.

Re: Xfce4-panel/lxpanel won't start in bullseye Openbox session

On a Beryllium (ie Bullseye) VM, xfce4-panel installed and ran OK. It did spew out a screenful of warnings, but nothing unexpected. The same as you had @hhh basically:
