在python中获取xscreensaver状态

Question

I'm running OpenSUSE Leap 42.3 with XFCE and it uses xscreensaver.

I want to somehow get True if screensaver is currently working. You can't just look at process list, xscreensaver always sits there.

Is there any easy way to do that?

Answer 1

Use the subprocess module to run xscreensaver-command :

def check_screensaver():
    p = subprocess.run(['xscreensaver-command', '-time'], stdout=subprocess.PIPE)
    words = p.stdout.decode().split()
    return 'blanked' in words:

This simple code looks for the word 'blanked' in the output. You could parse it further to extract the time it was activated/deactivated.
