#3957: Clicking Help on first screen does nothing

It's the user's very first use...
{{{
$ grass
}}}
Then click Help. Nothing happens.
Some error message should appear somewhere.
Maybe this help button should be greyed out unless the current screen is
doing a action that has a help page.

That's unexpected. It should open a browser and therein the helptext.html.
It respects the env variable `GRASS_HTML_BROWSER` and, if undefined, it
searches for numerous candidates:

Maybe your's is missing?

The question is: which operating system do you use? And: is any web
browser installed?

Comment (by jidanni):
OK, today it is working.
Standard Debian sid install. BROWSER=chromium.
Maybe it is now working because I have initialized the databases, etc.
However a vanilla
{{{
# su - some_vanilla_account
$ DISPLAY=:0 grass
BROWSER=chromium DISPLAY=:0 grass
Starting GRASS GIS...
(gis_set.py:16417): dbind-WARNING **: 01:53:33.208: Couldn't register with
accessibility bus: Did not receive a reply. Possible causes include: the
remote application did not send a reply, the message bus security policy
blocked the reply, the reply timeout expired, or the network connection
was broken.
}}}
and then clicking Help does nothing.

Probably you have to `export` the variables?

Putting them on the command line exports them.

I guess, in your case, it is more related to #3964

Comment (by wenzeslaus):
If you have `xdg-open` available, this should just work. It's the default
in `grass.py` for all systems except Windows and macOS.
I'm getting some strange behavior when I actually set the variable:
{{{
GRASS_HTML_BROWSER=firefox grass
GRASS_HTML_BROWSER=chromium grass
}}}
However, in that case, not even g.manual is working. Anybody else
observing this? If yes, can you just open a new issue on !GitHub for that?
