Re: Screensaver + Backlight (Power Off) Trouble

Let's have a try - let DPMS manage it instead of xscreensaver. Put these into your autostart:

xset s on &
xset dpms &

Re: Screensaver + Backlight (Power Off) Trouble

thanks machinebacon!

xset s on &
xset dpms &

these had no effect. after replacing xscrnsvr and xfce4-pwrmgr with those in autostart, and rebooting, the screen did not blank at all any more. well not after 25min at least.

i tried from the terminal:

xset dpms force off
xset dpms force suspend
xset dpms force standby
xset +dpms
xset -dpms
xset s 20

- they all worked, but immediately after blanking and backlight off, it unblanks again.

i tried killing off processes 1 by 1 and retrying xset s 20.
killing tint2, conky, iceweasel(firefox-bin), transmission, ...
still the same.

i searched "laptop power manage" in synaptic but only xfce4-power-mgr is installed.

so before i start shooting in the dark, is there anything else i can do?

desperately,

d.

Re: Screensaver + Backlight (Power Off) Trouble

yes i totally agree with that, but no, this is not the problem here.
the problem is that regrdless of which program i use for switching off the backlight, the screen lights up again immediately.

i tried disabling either xfce4-pwrmgmt or xscrsvr and also both but the problem persists.

and with disabling i mean commenting it out in autostart and rebooting.

right now i'm running neither, just some xset-magic as described by machinebacon - but the problem persists. duh.
