Multi-monitor Support on Cage

[CaitlinDavitt]

Hello, I was trying to use ReGreet with two monitors, and it ended up spanning one login screen across the middle of both monitors, which was difficult to use. Would there be a way for it to either have ReGreet on just one monitor, have one screen with the login and one with just the background, or have ReGreet on both of the monitors? Thanks.

Could you post your compositor (the one used to launch ReGreet) config? I tried this with Sway, and it opens ReGreet on a single monitor, while the other monitor stays greyed out.

I can also set the other monitors to display the background image using swaybg in the Sway config. For this, I added this line to my Sway config:

exec swaybg --image "/path/to/background/image.jpg"

Though, this method has the downside that you need to install another application swaybg to set the background image.

I can reproduce this with an external monitor plugged in. Here's my Sway config:

exec "regreet; swaymsg exit"

bindsym Mod4+shift+e exec swaynag \
-t warning \
-m 'What do you want to do?' \
-b 'Poweroff' 'systemctl poweroff' \
-b 'Reboot' 'systemctl reboot'

include /etc/sway/config.d/*

@TheSunCat Could you also post the contents of all files under /etc/sway/config.d? I had nearly the same Sway config (without the bindsym) when I last tested this.

EDIT: Please also include your Sway version, GTK version, and your OS version.

If anyone still has this issue, please try the latest main branch code. I added a commit for some basic multi monitor support, which should theoretically help with this issue.

I can confirm that the git aur package as of today had this issue with cage for me but when I switched to sway as above it worked fine.

[rharish101]

Okay, in that case I'll close this issue. If anyone still has issues, feel free to comment here. I'll then reopen this issue.

I am trying to get this to work with cage, because I do not use sway by default. Tried with hyprland, did not work...

[ValouBambou]

The issue is still here (arch linux official package) using cage, also I tried to use sway instead but the window with login, session doesn't appear.

EDIT: I understood the doc about sway and manage to solve the issue using sway, but the issue still exists with the default config using cage.

Came here because I'm suffering the same issue. I am using the arch official package and cage on hyprland.

You can make it on one monitor with this option:

-m <mode>

Set the multi-monitor behavior. Supported modes are: last Cage uses only the last connected monitor. extend Cage extends the display across all connected monitors.

Basically do cage -mlast -- regreet, you probably also want -d -s, lookup what those mean in cage.
