Bug: mons -s works only one time

[cserb]

So I started to have the following problem:

I start Xorg and type in mons -s. It would switch as expected (though leaving the primary monitor turned on) to the second monitor. Now type mons -o (works) and I type mons -s again. Second time it wouldn't work and I need to restart Xorg to make it work again.

If I use xrandr it works all the time and it also properly turns off the primary monitor:

xrandr --output eDP-1 --off --output HDMI-1 --auto
xrandr --output eDP-1 --auto --output HDMI-1 --off

What exactly is the xrandr command when mons -s is executed?

Hi @cserb, Thanks for your feedback.

It does (let's say A is the primary monitor and B the second one):

$ mons -s
xrandr --output A --off
xrandr --output B --auto --dpi "$dpi"

$ mons -o
xrandr --output B --off
xrandr --output A --auto --dpi "$dpi"

Could you please give me some information about your environment ?

What is the result of the following command:

$ xdpyinfo | grep dots

$ xdpyinfo | grep dots
resolution:    162x162 dots per inch

mons sets the dpi at 96 by default. Try again with the --dpi DPI option.

$ mons -o --dpi 162
$ mons -s --dpi 162

The issue could come from there.

[cserb]

Works now... so this seems to have been the issue.

There is one more minor annoyance , that the original screen stays on showing the upper left corner of the bigger screen. Again this doesn't happen if I use xrandr directly.

[Ventto]

Okay, I will remove the dpi setting of 96 by default while keeping the --dpi VALUE option
