No desktop icons or taskbar with realvnc

Mon Aug 02, 2021 4:27 pm

I have installed the latest unbuntu desktop (20.something) on my rpi 4 vía the raspberry sd card writer. I enabled ssh and installed realvnc server. I installed the xfce desktop and lightdm.
I am able to login via VNC from my windows VNC viewer but all I get is the empty Ubuntu desk top with the realvnc window telling me I successfully connected. However, there are no icons or taskbar and the keyboard and mouse don’t respond. I.e., ctrl-alt-t doesn’t start a command window, and the mouse moves but doesn’t respond to right or left click.
I only have remote access right now via ssh and defective realvnc; no monitor or keyboard.
I know I’m missing some simple step to get the full desktop. Any suggestions?
Thanks,
Eddie

RealVNC Server seems to be fully functional for me using the recommended and supported Raspberry Pi Buster [32] Operating System on the RPi.


Perhaps this is something to take up with RealVNC and/or Canonical?

Could be. I am not sure whether it’s a realvnc, Ubuntu desktop setup or 32/64 bit os/app issue. I don’t have a monitor available right now to see if I have a functional desktop directly. I was suspecting it is the way I’ve set up ubuntu xfce desktop, I.e.not enabling it correctly.

I was able to get access to my monitor, keyboard and mouse briefly. (It is being used for ‘real’ work so I only get it occasionally.) When I first connected it was at a login screen with many characters in the password field. I was able to log in and the desktop functioned correctly. I left it logged in and reconnected with realvnc. It was very sluggish and worked long enough to bring up a file app. It soon stopped completely. I rebooted and it is back like it was before.
I suspect now that the realvnc server is connecting and finding a prompt it is not handling. There is something about virtual vs real desktop sessions I’m missing, I think.
Any suggestions about what to look at?

finally...
in /etc/gdm3/custom.config i uncommented the line Wayland=false and rebooted
I got the login screen for ubuntu and selected the xfce session like I wanted. logged in with my username and password and everything works.

just as a way of documenting everything here is what I did.
btw... it is Ubuntu 21.something
