I installed Ubuntu Server 64-bit and installed
udo apt install ubuntu-budgie-desktop with the
gdm3 option (instead of
lightdm). Login as
ubuntu was possible. However the Desktop was not started. Trying to start
gdm3 manually lead to:
ubuntu@ubuntu:~$ sudo service gdm3 start
Failed to start gdm3.service: Unit gdm3.service not found.
gdm3 had to be installed explicitly with
sudo apt-get install gdm3 -y. After a
reboot I could login. However when I hovered over the icons in the bottom to start
Firefox the screen freezed. This happened several times. In summary the result was not satisfying.
lightdm instead of
gdm3 and let you know about the results @fossfreedom .
