Bug#397197: DPMS-bug test scenario
I'm pleased to announce a reliable and fast test scenario:
$ xset dpms 10 20 30
[wait 10 seconds]
[screen goes blank (DPMS gets active)]
$ xset -dpms
[no DPMS kicks in, not even after 10 seconds]
$ xset +dpms
[wait 10 seconds]
What I now expect is that DPMS suspends (or actually "standbys") the
screen, but that does not happen. The screen stays visible, passing 10,
20, 30 and more seconds.
Can anybody confirm that on other systems?
I run
X Window System Version 1.3.0
Release Date: 19 April 2007
The -dpms and +dpms (or probably something equivalent) gets used by
video players to avoid black screens while watching a movie... I use
mplayer and checked with "xset q" -> "DPMS is Disabled" but only while
mplayer is running.
That means for me that after the first invocation of mplayer DPMS does
not work anymore.
Greetings,
Robert
