Incorrect Screen Resolution Detection in swww for 4K Monitor in Portrait Mode with Hyprland
Hello! I'm using a computer with two monitors.
Hyprland 0.45.0 built from branch swww version: 0.9.5
~/.config/hypr/monitors.conf:
# Generated by nwg-displays. Do not edit manually.
monitor=DP-2,[email protected],1507x0,1.5
monitor=DP-2,transform,3
monitor=DP-3,[email protected],2947x360,1.0,bitdepth,10
xrandr output:
DP-3 connected primary 2560x1440+2160+0
DP-2 connected 2160x3840+0+0
DP-2 is a 4K monitor in portrait mode (vertically oriented).
Current issue upon startup: swww query output:
DP-2: 2560x1440, scale: 1.5
DP-3: 2560x1440, scale: 1
In this scaling mode, swww doesn’t stretch the wallpaper to cover the entire screen because it detects DP-2 as having a resolution of 2560x1440 and centers the image instead.
Workaround:
If I edit the line:
monitor=DP-2,[email protected],1507x0,1.5
to
monitor=DP-2,[email protected],1507x0,1.0
and then change it back to
monitor=DP-2,[email protected],1507x0,1.5
while Hyprland is running, swww then shows the correct resolution in swww query:
DP-2: 1440x2560, scale: 1.5
DP-3: 2560x1440, scale: 1
I have a similar issue after upgrading Hyprland. My portrait monitor will not crop the image anymore, instead showing black (not --fill-colors) around a centered image.
swww query reports the screen's resolution, but not anything about it being rotated.
> swww query
DP-1: 2560x1440, scale: 1, currently displaying: image: …
DP-2: 2560x1440, scale: 1, currently displaying: image: …
DP-3: 2560x1440, scale: 1, currently displaying: image: …
DP-3 is rotated and I would assume it should be displaying 1440x2560 instead.

Hyprland, built from branch v0.44.1-b at commit 4520b30d498daca8079365bdb909a8dea38e8d55 (version: bump to 0.44.1).

Tag: v0.44.1, commits: 4520b30d498daca8079365bdb909a8dea38e8d55
built against aquamarine 0.4.3
Thankfully this happened after I bumped my NixOS build, so I have an easy time to diff the changes in versions between the build. I think these might be related:
[U.] #004 aquamarine 0.4.1 -> 0.4.3
[U*] #084 hyprland 0.43.0, 0.43.0-man -> 0.44.1, 0.44.1-man
I think it might relate to this Hyprland issue, where people conclude that latest main of swww works. There's a lot of unreleased commits in main right now.
I don't care enough about this problem right now to switch to a from-source version of swww, but these are the breadcrumbs I found. Maybe it will be helpful to someone. :-)
Adding to the above, I Just installed swww yesterday and had the same issue, in addition to other vertical monitors strange behaviours. Replacing the swww package -- which seems stale -- with swww-git fixed it for me.
I am also running into this issue. I have a 1920x1080 that I have configured to be portrait on hyprland. My first monitor is fine, but my portrait monitor has the background centered instead of filling the whole screen.
$ swww --version [20:38:56]
swww 0.9.5
EDIT: I was able to fix this by using master instead: https://github.com/eureka-cpu/dotfiles/blob/249ddd76464cf94de462f06a8e2e41ec9fe3c24d/flake.nix#L11
This should be fixed by PR #439. I will be closing it for now, but feel free to reopen it if it still doesn't work.
