I'm using KDE on Manjaro Linux. I'm building Handbrake from source.
In KDE, I've set the display/monitor standby to 20 minutes - and I'm having the issue, that sometimes the display just doesn't turn off as it should be. After a while I realized, that this issue occurs only when the Handbrake GUI is open and encoding. The display does turn off (after the idle time) if the GUI is only open but no job is running. So far Handbrake seems to be the only application having this influence on the standby mode.
Now if I run "xset -q" while Handbrake GUI is open but idle, I get:
Code: Select all
$ xset -q
[...]
DPMS (Energy Star):
Standby: 1200 Suspend: 1800 Off: 2400
DPMS is Enabled
Monitor is On
Code: Select all
$ xset -q
[...]
DPMS (Energy Star):
Standby: 0 Suspend: 0 Off: 0
DPMS is Disabled
So I'm not sure where to look next!? Why is it doing this? Any ideas?
The only idea I have for now is to test other CPU intensive programs, if they produce the same result. But still I would have no idea why? I really can't imagine an OS or DE "feature" that disables display standby if there is a high CPU load.
Just wanted to ask here if anyone maybe had the same issue?
