How to identify with desktop environment id installed to configure lightdm-theme

  • 772

I have a creepy problem here. I have to identify the desktop environment installed by an user without to know with one it's used by a user to change the user session value in some lightdm-files.

The user can select between

  • Unity
  • Gnome3
  • Mate
  • Xfce
  • Pantheon
  • Kde
  • Lxde
  • Cinnamon
  • Enlightenment

I have to change the user-session value in more than one file here is an example

[SeatDefaults]
greeter-session=lightdm-webkit-greeter
user-session=value-to-cahgne

To determine the package I have the following code

usersession() {
if  dpkg-query -l package to check for > /dev/null; then
setunty
elif  dpkg-query -l package to check for > /dev/null; then
setgnome
elif dpkg-query -l package to check for > /dev/null; then
setmate
elif  dpkg-query -l package to check for > /dev/null; then
setxfce
elif ! dpkg-query -l package to check for > /dev/null; then
setpantheon
elif dpkg-query -l package to check for > /dev/null; then
setkde
elif  dpkg-query -l package to check for > /dev/null; then
setlxde    
elif dpkg-query -l package to check for > /dev/null; then
setcinnamon
elif dpkg-query -l package to check for > /dev/null; then
setenlightenment
fi
}

The string "package" to check for in the above code is what needs to be replaced.

What strings should I use to check dpkg -l for the current desktop environment?
