Make xfce4-screensaver lock on a specific display

Toad39 · 2024-01-06 00:30:48

Hello,

I am using xfce4-screensaver with xflock4. However, when it locks, it often locks on my vertical monitor, I keep off most of the time so I don't see the lock screen unless I turn the monitor on (for some reason, the monitor is still sometimes detected by operating systems even if it's off).

How do I set xfce4-screensaver/xflock4 to always lock on the display I want?

Thanks

xrandr -q

Is the vertical the primary one ?

DP1 is my vertical monitor. HDMI2 is my horizontal (and primary) monitor.

It's also the one on the left, what happens if you don't vertically center it but put it at +0+0 ?
(Just trying to understand the logics the screenlocker applies here, you'll probably have to file an upstream bug about this. Or use xscreensaver or i3lock etc)

However the vertical monitor is physically on the right, and set to be on the right in xfce display settings.

Not centering the monitors doesn't work.

Perhaps the underlying problem is that the vertical monitor is detected even though it's left off (though this happens on Windows too, so it may be a hardware issue). Should I make a new thread for that, or would we troubleshoot it here?

You can "xrandr --output DP1 --off", the power state of the output doesn't directly matter itr.

Interestingly xfce enumerates the vertical output as "1"… (for whatever reason, but likely the alphabet…)

I still can't get this to reproduce consistently, so I'm giving up for now. I swapped the monitors (so DP1 is now my primary, horizontal monitor and HDMI2 is my vertical one) and it still happens, but seemingly less.
