Mouse to end sleep

When I computer goes to sleep (and I think it is xscreensaver controlling this) a simple key press will wake it up. However, a mouse movement or click will also do so, but it does not actually work. The monitor turns on (I get a green status light on the monitor and a monitor message about <dvi-0> being active). But, I sill need to press a key to stop the screen saver. Can I fix this so that a mouse action or a keyboard hit work the same?

Re: Mouse to end sleep

Well, figured this out ... a bit of sleuthing.

Problem was that both cinnamon-screensaver and xscreensaver were running. Bad: Only one screen saver should be running!

Stopping xscreensaver was pretty simple since it was listed in my session->autostart. So, now I have cinnamon-screen saver only.

However, I have been unable to achieve the opposite: Have xscreensaver running but no cinnamon-screensaver. Anyone know were this is called?

Re: Mouse to end sleep

I'm not too familiar with cinnamon, but isn't their screensaver baked into the daemon? Meaning it can't be disabled? Is the cinnamon daemon running? Maybe killing or stopping the process would disable it.

Re: Mouse to end sleep

I looked at the program /usr/bin/cinnamon-screensaver and it's just a python script which calls (I thing) the gnome screensaver.

#!/usr/bin/python3

import gi
gi.require_version('Gtk', '3.0')
gi.require_version('GdkX11', '3.0')
gi.require_version('CScreensaver', '1.0')

signal.signal(signal.SIGINT, signal.SIG_DFL)
gettext.install("cinnamon-screensaver", "/usr/share/locale")

    main = Main()

From that point on I have no idea smile Yes, I could kill the process when I log into an xfce4 session ... but that really sounds like the "hard way" to do thing. Not a big deal ... but it is odd.
