slock will always show a black screen but is the monitor actually turned off<br>
with DPMS - my monitor shows "Entering power save mode" when this happens and<br>
turns off the back light.<br>
<br>
Try this: in a terminal type "xset dpms force off" and press and hold the enter<br>
key for one second before releasing it. The key press event will cause the<br>
execution of the xset command, but then the release event will wake the monitor<br>
back up. The same happens with the ctrl-alt-delete shortcut.<br>
<br>

<br>
<br>
The explanation:<br>
<br>
"You're using it manually from command line or xset is binded to some keyboard<br>
shortcut? On my brother laptop this command was binded to some keys and after<br>
that monitor was turned off and on again, because when he was releasing key<br>
next event was emitted. Turning it off after quick sleep solved problem: perl<br>
-e 'select(undef,undef,undef,.1)' && xset dpms force off - this perl expression<br>
do sleep for 0.1 sec."<br>
<br>
The timeout has to be longer than the delay between a person pressing the enter<br>
key and then releasing it.<br>
