In order to choose between what type of app indicators to use for a program, I need to detect whether I'm in a Unity desktop or not. Is this possible? Is it possible when I don't have access to the environment?

It looks like there's also XDG_CURRENT_DESKTOP:
rubiojr@rubiojr-VirtualBox:~$ echo $XDG_CURRENT_DESKTOP
Unity

In Ubuntu you can use following commands:
- echo $DESKTOP_SESSION: This command return ubuntu when you are using Unity and ubuntu-2d when you are using Unity 2D and ...
- sudo grep "Starting session" /var/log/lightdm/lightdm.log: Because of last version of Ubuntu use lightdm as display manager you can see last line of the lightdm.log file.
Just shell execute ps aux | grep unity
, this is cross-plattform for linux. Even works on ARM cores.
On my 11.04 Ubuntu running unity it returns unity-2d-panel, unity-2d-launcher and more processes. Can't confirm if this is true on every linux platform.
Look in the list of environment variables for unity by running this command line:
env | grep -i unity
If as in this answer you see XDG_CURRENT_DESKTOP=Unity
then you know it is in use. Alternatively, you could of course check for desktop
rather than unity
.
