You have to write the definition of your env variable into /etc/profile :


If that doesn't work, you could try /etc/environment

That won't reach all processes, only those started from a users shell. – arkascha Oct 4 '12 at 8:00
I added /etc/environment – FSMaxB Oct 4 '12 at 8:11
Sounds better, though it depends on the PAM configuration. I wonder if it is possible to hand that environment variable to the init process. All other processes are started by that one, so they all inherit that variable. – arkascha Oct 4 '12 at 9:18
