I have vnc working fine with a GUI on my BB AI. But if it plug in a display and keyboard/mouse i get a text terminal and can’t start up a graphical desktop. startx is not found.
What packages do I need to install for that? If it works over VNC why doesn’t it work directly?
thanks
Hi Bernard
I am fairly sure he has a display manager installed as VNC will not function without one.

graphical desktop. startx is not found.
Off hand, that behavior sounds much like you have X-clients installed,
but not an X-server; the VNC software on the Beagle may be acting as the
server when it is running. cf:
https://www.debian.org/doc/manuals/debian-reference/ch07.en.html

See above answer... Your X clients (applications) are sending drawing
commands to the VNC server on the Beagle, which relays them to the VNC
client on the other computer for display. Note: the desktop manager is a
/client/ application. {Note: the usage of server/client WRT VNC is opposite
of the usage for pure X Window. In X, the /display/ doing the rendering is
the server, clients send commands to the server over the network -- But
with VNC, the software on the Beagle is intercepting the commands and
reformulating them for VNC network protocol}
On a BBB with IoT image (and stripping out a lot of extraneous
packages):

AFAIK VNC can be configured to work either independently or with a display manager. Depends on how Bernard has configured the VNC server on his BB, which he didn’t specify.
If he connects with VNC directly to a display manager, e.g. GDM, then yes he should see the same GDM login window on native terminal. If it’s not there, perhaps it helps to walk through the virtual terminals Ctrl-Alt-F1 to Ctrl-Alt-F7 - it might show up somewhere.
Hello,
I am not sure if you have figured out this issue yet or not. Please view this article. It is a bit lengthy to post the entire article in this post: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-debian-10.
There is a section on it that describes how to install xfce4 on Debian 10 (GUI), a section to set up for booting into that GUI, and I think it may help your cause.
