I just downloaded GNOME-Shell. And at login screen it's give me to choose to set desktop environment, But I want to set GNOME as my default desktop environment.
Although I tried the possible suggestions on this site like
pnath@ubuntu:~$ sudo /usr/lib/lightdm/lightdm-set-defaults -s gnome-shell
[sudo] password for pnath:
sudo: /usr/lib/lightdm/lightdm-set-defaults: command not found
pnath@ubuntu:~$
And this
gksu gedit /etc/lightdm/lightdm.conf
and this:
Open a terminal and cd
to /etc/lightdm/lightdm.d
, create a file called 50-ubuntu.conf
with the following command sudo nano 50-ubuntu.conf
.
Add the following two lines.
[SeatDefaults]
user-session=gnome
then reboot and gnome should be your default session.
When I tried output is this:
pnath@ubuntu:~$ cd /etc/lightdm/lightdm.d
bash: cd: /etc/lightdm/lightdm.d: No such file or directory
pnath@ubuntu:~$
this did not change anything
Please give me any other solution

(This answer was tested with Ubuntu 14.04. It is probably not useful for newer Ubuntu editions)
I do not know about ligthDM (@muru confirm that lightDM behave the same), but if you use gdm as display manager the default session is simply the last one you choose (at least, it was --- I hope they didn't change this; can't test now because I removed all desktops minus the gnome-shell one).
To install
gdm
(which, by the way, is the best thing to do if you want gnome-shell --- I had problems with gnome-shell + lightDM), simplyIf you have it already installed, just
will ask you which display manager to use.
Then when you login, you choose
Gnome
as the desktop you want, and the subsequent login that will be the default.
