randr changes are not handled

[dakyskye]

Describe the bug I have custom xrandr setup, and bar only appears on ONE of the my screens, not on both.

To Reproduce

1. write custom xrandr config to $HOME/.xprofile
2. log out
3. log in
4. see it

Expected behavior Bar should be drawn on both monitors

Screenshots

Additional context That's my .xprofile content:

xrandr --output DisplayPort-0 --off --output DisplayPort-1 --off --output HDMI-A-0 --mode 1920x1080 --pos 1360x0 --rotate normal --output HDMI-A-1 --mode 1360x768 --pos 0x312 --rotate normal --output DVI-D-0 --off

I turned it into xorg config file:

Section "Monitor"
	Identifier  "HDMI-A-0"
	Option      "Primary" "true"
	Option      "PreferredMode" "1920x1080"
	Option      "TargetRefresh" "60"
EndSection

Section "Monitor"
	Identifier  "HDMI-A-1"
	Option      "LeftOf" "HDMI-A-0"
	Option      "PreferredMode" "1360x768"
	Option      "TargetRefresh" "60"
EndSection

and it now works fine. But it should also work work with my previous method.

Nimdow doesn't detect changes to the monitor layouts yet, but this would be good to add soon

[avahe-kellenberger]

Some thoughts: we should receive a ConfigureNotify event for the root window when this happens. At that point, we can adjust the size of each monitor and its bars

[avahe-kellenberger]

Notes

man 3 xrandr:

A XRRScreenChangeNotifyEvent is sent to a client that has requested notification whenever the screen configuration is changed. A client can perform this request by calling XRRSelectInput, passing the display, the root window, and the RRScreenChangeNotifyMask mask.

May not need xrandr here.

See how dwm handles this (configurenotify and updategeom functions).

2 years and still not been done? any update when multi monitor will work?

[avahe-kellenberger]

Multi-monitor works well, just not changes made after Nimdow has been started

I did try to get multi monitor to work on arch but failed to get it working :) I can get the wallpaper on both but it doesn't let me move things to the 2nd monitor or even open anything on it even if rules tell it too :) it doesn't seem to like xrandr :)

[avahe-kellenberger]

Yes, you need to set up your monitor layout before starting Nimdow - many of us, myself including, are using 2+ monitors just fine

I did try the xorg config above but with one being Nvidia and other being Intel they don't seem to want to play nice :) eDP1 and HDMI-1-0 are my monitors one being the laptop and the other being Nvidia HDMI. I have no idea why it can only pick up 1 or the other it doesn't wanna activate HDMI and eDP at the same time

I have just tried the config below but it still has the 2nd monitor as inactive in arandr

Section "Monitor"
	Identifier  "eDP1"
	Option      "Primary" "true"
	Option      "PreferredMode" "1920x1080"
	Option      "TargetRefresh" "60"
	Option      "Enable" "true"
EndSection

Section "Monitor"
	Identifier  "HDMI-1-0"
	Option      "RightOf" "eDP1"
	Option      "PreferredMode" "1920x1080"
	Option      "TargetRefresh" "60"
	Option      "Enable" "true"
EndSection

People in the discord may be able to help you, or any general Linux forum. This is about getting your config correct and doesn't have to do with Nimdow
