Hello all,

after upgrading to MGA9 my HP 24" monitor is no longer switched off automatically after a certain time.
I have set xscreensaver as the default screensaver,
in xfce4 "Application autostart" Power manag. is set to start on login,
in xfce4 power manager, "Display power management" is set to "switch off after" 15 min.
If I wait for that time and don't touch anything, the monitor still shows xscreensaver's pictures.

Anyone have a solution, or know how to test in detail?

Thanks!

Best regards,

Markus

You can use "xset q" to see the current screen saver and dpms settings, rather then
waiting to test them.

The xscreensaver program overrides desktop environment settings using /etc/X11/app-defaults/XScreenSaver. Uninstall xscreensaver-common and xscreensaver
and chbg, if you're not going to be using xscreensaver, or change the settings, settings. Reboot (likely logout/in would be enough) after changing the settings or
uninstalling the packages.

The xscreensaver package is primarily meant for use on desktop environments that do
not include a screen saver or power management feature, though it can be used in
other desktops.

I find it's easier to use a script rather then dig through the settings of each desktop environment. In my case, I normally do not want any screen saver or blanking.

I have two scripts ...
[dave@x3 ~]$ cat ~/.config/autostart-scripts/noblank
#!/bin/bash
/home/dave/bin/noblank &

[dave@x3 ~]$ cat ~/bin/noblank
#!/bin/bash
sleep 60
xset s 0 0
xset s noblank
xset s off
xset dpms 0 0 0
xset -dpms

The sleep 60 allows the desktop to set things as it's configured, and then the script overrides them. By having the first script start the second in the background, the second script doesn't hold up starting the desktop.
See "man xset" for the various configuration options available.

I haven't looked into how to do this if you're using wayland instead of xorg.

In MGA9 there are many things messed up. What I've found out is, for
instance, that xfce's energy settings do not take effect at all, though
they look like coworking with xscreensaver's settings, and xscreensaver "forgets" its settings, so that every checked box is unchecked after
leaving and reentering. So, it's never clear what xscreensaver does. After opening the settings form and reading the values, they should be displayed correctly, as it was in former versions.

Hmm!! "so that every checked box is unchecked after leaving and
reentering" .... Could it be the preferences file is set to "Read Only"??

Hi, good point, thanks!
Unfortunately, that seems not to be the "root cause" -- I tested with a
newly created user and empty home space and the same occurred.
