Bug

Description

When using wlr-randr/ wdisplays or wlr-layout-ui to change the layout of my 2 screens no change occurs. The layout remains the same.

How to reproduce

1. Initial layout after connecting 2nd monitor

❯ wlr-randr
DP-4 "Samsung Electric Company LU28R55 HNMNB00590 (DP-4 via HDMI)"
  Make: Samsung Electric Company
  Model: LU28R55
  Serial: HNMNB00590
  Physical size: 630x360 mm
  Enabled: yes
  Modes:
[SNIP]
  Position: 2256,0
  Transform: normal
  Scale: 1.000000
  Adaptive Sync: disabled
eDP-1 "BOE 0x095F (eDP-1)"
  Make: BOE
  Model: 0x095F
  Serial: (null)
  Physical size: 280x190 mm
  Enabled: yes
  Modes:
[SNIP]
  Position: 0,0
  Transform: normal
  Scale: 1.000000
  Adaptive Sync: disabled

2. Manually apply layout change with wlr-randr

❯ wlr-randr --output DP-4 --on --pos 0,0 --mode 3840x2160 --output eDP-1 --on --pos 792,2160 --mode 2256x1504 ; echo "return code: $?"
return code: 0

3. Layout after wlr-randr

❯ wlr-randr
DP-4 "Samsung Electric Company LU28R55 HNMNB00590 (DP-4 via HDMI)"
  Make: Samsung Electric Company
  Model: LU28R55
  Serial: HNMNB00590
  Physical size: 630x360 mm
  Enabled: yes
  Modes:
[SNIP]
  Position: 2256,0
  Transform: normal
  Scale: 1.000000
  Adaptive Sync: disabled
eDP-1 "BOE 0x095F (eDP-1)"
  Make: BOE
  Model: 0x095F
  Serial: (null)
  Physical size: 280x190 mm
  Enabled: yes
  Modes:
[SNIP]
  Position: 0,0
  Transform: normal
  Scale: 1.000000
  Adaptive Sync: disabled

If I understand this correctly, hyprland re-applies the layout it has auto-determined during startup.

Not sure if this is a regression, #110 looks very similar but didn't provide any debug logs to compare against.

generally I'd recommend using hyprctl...

[fdev31]

@vaxerski maybe I'm not getting it, isn't hyprctl only able to set new settings only ? (vs update/replace existing ones)
Maybe I miss some piece of documentation, if that's clear to me I may drop the wlr-randr dependency...

EDIT:
Can hyprctl list the valid options for a given (or all) monitors ?
Else wlr-randr can't be replaced...

[vaxerski]

Can hyprctl list the valid options for a given (or all) monitors ?

you mean valid modes?

it does that.

[fdev31]

Hmmm... I'm not seeing it in the changelog but I'm running an old 0.35.0, I guess this is a recent addition. I'll have a look once I'm back from holidays, thanks!

[vaxerski]

it was added in 0.37

[fdev31]

@dantefromhell I pushed some untested code in the "next" branch of pyprland to not use wlr-randr : https://github.com/hyprland-community/pyprland/tree/next

Also pushed some similar experimental code in https://github.com/fdev31/wlr-layout-ui

I'll only be able to test next month when I have my usual setup but it may work ;)

[dantefromhell]

I've decided to use hard-coded monitors rules in my hyprland.conf file. Not sure if it's relevant to keep this issue open.

Came across the same issue on my end. Running on Hyprland-git from the AUR v0.43.0-79-gd73c1475
I ran wlr-randr --output eDP-1 --toggle although nothing happened then ran hyprctl rollinglog -f to see whats going on.
My debug output in hyprland is below.

Only have a default monitor rule for my laptop screen which is 1920x1080, without the monitor rule it just defaults to 1280x720 not sure why. Even removed that monitor rule for the laptop screen but nothing happened.

It was fine last week but after updating Hyprland can't use wlr-randr any more for monitor management. So am just hard coding values like @dantefromhell.
