Description

Monitor config has for a long time looks as follows:

monitor = desc:LG Electronics 34GN850 004NTBK70749, preferred, auto, 1
monitor = desc:Dell Inc. DELL U2715H GH85D69U092S, preferred, auto, 1, transform, 3

This has always worked great, with the LG being the main monitor with my Dell to the right side, rotated 90 degrees. The “auto” positioning set the Dell with an x offset of 3440, which is the width of the LG.

This broke when I updated today, with auto positioning resulting in both monitors at 0x0.

I haven’t done a proper git bisect, but looking through the history since my last update (4 days ago) the most likely culprit is 13886a2, which introduces a new monitor handling system. According to the documentation the “auto” positioning should still work the same, so I’m assuming this is a bug. Explicitly setting the position of both monitors in config resolves the issue as a temporary fix.

How to reproduce

Start hyprland with two monitors set for auto positioning. The expected outcome is the first monitor at 0x0 and the second at (width of first monitor)x0. The actual outcome is both at 0x0.

Same here though in my case it seems that removing the line specifying DP-1 solves it for me. It seems like setting DP-1 causes Hyprland to forget the DP-2 line.

patch.txt try this

Manual positioning still isn’t respected, I get same output from hyprctl monitors.

But auto positioning seems like it works properly.
