Ciao a tutti
Sto usando Ubuntu 20.04 Server su RPI 4
Ho seguito questa guida per installare la GUI: https://www.servermania.com/kb/articles/...erver-gui/


Ora ho questo problema:

Codice:

~$ systemctl status display-manager.service
● lightdm.service - Light Display Manager
Loaded: loaded (/lib/systemd/system/lightdm.service; indirect; vendor preset: enabled)
Active: failed (Result: exit-code) since Thu 2022-03-17 08:27:07 UTC; 1h 3min ago
Docs: man:lightdm(1)
Main PID: 1867 (code=exited, status=1/FAILURE)


Mar 17 08:27:07 ubuntu systemd[1]: lightdm.service: Scheduled restart job, restart counter is at 5.
Mar 17 08:27:07 ubuntu systemd[1]: Stopped Light Display Manager.
Mar 17 08:27:07 ubuntu systemd[1]: lightdm.service: Start request repeated too quickly.
Mar 17 08:27:07 ubuntu systemd[1]: lightdm.service: Failed with result 'exit-code'.
Mar 17 08:27:07 ubuntu systemd[1]: Failed to start Light Display Manager.

Anche cambiando display manager:

Codice:

~$ systemctl status display-manager.service
● gdm.service - GNOME Display Manager
Loaded: loaded (/lib/systemd/system/gdm.service; static; vendor preset: enabled)
Active: inactive (dead)

ovviamente non riesco a lanciare RealVNC:

Codice:

~$ vnclicensewiz

Il problema è che non ho raspi-config su ubuntu

[denenr]

https://github.com/EmilGus/install_raspi-config/

ho intallato raspi-config

da Advanced-Option > Resolution: mi da come unica opzione Default Monitor Preferred Resolution, e accettando mi dice The resolution is set to default.

Da Interface Option > VNC ho abilitato il server VNC

Quando avvio un collegamento con RealVNC mi dice ancora "Cannot Currently Show the Desktop"

Sempre da raspi-config, Boot Option > Desktop/CLI > Desktop autologin, mi dice

Codice:

sed: can't read /etc/lightdm/lightdm.conf: No such file or directory

Mi sa che e' proprio l'installazione della GUI che non e' avvenuta con successo devo dire.
Puo' essere un problema legato al fatto che non essendoci un monitor collegato non viene mai inizializzata l'interfaccia GUI?
