Ubuntu – Ubuntu 17.04 does not boot when enable gdm3

17.04gdmgnomegnome-shell

Recently I switched from Ubuntu 16.10 to Ubuntu 17.04. Reading this news, Ubuntu 18.04 To Ship with GNOME Desktop, Not Unity, I decided to switch to gnome.

sudo apt-get install gnome-shell gnome

At this point all works fine and can start the session using gnome without problems.

But when try to switch to gdm3 and reboot the system does not boot. Switching back to lightdm and the system start ok. Im misssing something?

Resolved with:

apt-get install ubuntu-gnome-desktop

the entire install line to switch from unity to gnome should be

sudo apt-get install ubuntu-gnome-desktop gnome-shell gnome

Add the following line to /etc/lightdm/lightdm.conf file ( if it doesn't exist - create it. File must be owned by root )

[SeatDefaults]
user-session=unity

That will make unity default for all users, but remember what mikewhatever said: if you choose a specific session once, login screen will remember it.

You should probably switch to lightdm.

I also had problems with gdm in Ubuntu 17.04 mainly about logging in. I had to go to recovery mode and use dpkg to change it back to lightdm.

It may be because the transition from unity to gnome-shell is only partial in ubuntu 17.04.
