Checking whether X is running at login

daihard · 12-01-2006, 11:03 AM

Hi.

I would like to be able to check whether or not X is running at login time. Namely, I'd like to be able to do something like this in ~/.bash_profile.

Code:

if [ "$X_RUNNING" = "" ]; then
    echo "X is NOT running..." > x_output.txt
else
    echo "X is running..." > x_output.txt
fi

The question is, what kind of environment variable can I use for this purpose (in place of the imaginary X_RUNNING)? Or is there another way? Any help/feedback would be appreciated.

TIA,
Dai

Try $DISPLAY.
