I have a problem where monitors connected via docking station fail to reconnect if, I believe, the screensaver has been activated.
I'm using debian testing without a desktop environment (ie only a window manager). gsettings says screensaver should be disabled:
$ gsettings get org.gnome.desktop.session idle-delay
uint32 0
$ gsettings get org.gnome.desktop.screensaver lock-enabled
false
But overnight, while monitors are physically switched off (see the linked problem to see why), they fail to connect.
Question is - what setting/command can switch power-saving/screensaver/anything related off so the screens are never turned off by software?
I suspect dpms is the key here, but can't seem to disable it:
$ xset dpms 0 0 0
$ xset q
/--/
DPMS (Energy Star):
Standby: 0 Suspend: 0 Off: 0
DPMS is Enabled
Monitor is On
