I installed ubuntu on my raspberry and i currently have access via ssh. My goal is to install the KDE desktop (I did) and connect via VNC.
I followed this guide here (but I installed TightVNC): LINK
it's strange because the desktop is all gray but if I do crtl + alt + del it shows me the screen:
So I have TigerVNC, KDE and Ubuntu 22.04. I tried connecting with both TightVNC Viewer and VNCViewew.

sudo update-alternatives --config x-session-manager
Sono disponibili 4 scelte per l'alternativa x-session-manager (che fornisce /usr/bin/x-session-manager).
Selezione Percorso Priorità Stato
------------------------------------------------------------
0 /usr/bin/gnome-session 50 modalità automatica
1 /usr/bin/gnome-session 50 modalità manuale
* 2 /usr/bin/startplasma-x11 40 modalità manuale
3 /usr/bin/startxfce4 50 modalità manuale
4 /usr/bin/xfce4-session 40 modalità manuale
I hope there are enough elements to find the problem :/
