Qtile has the wrong index for the monitor.

The issue:

I wanted to get monitor index same as result of xrandr --listmonitors, but qtile missmatch with it.

First is log of using my func of cycleing monitor using screen index. Second is result of `xrandr --listmonitors’ Qtile reported monitor0(DP-0, primary, WQHD)->monitor1(DVI-D-0, FHD)->monitor2(HDMI-0, WQHD) but xrandr reported DP-0->HDMI-0->DVI-D-0. I use display config generated by nvidia-setting. (Third is)

• Qtile version: 0.21.1
• distro: ArchLinux
• I make screen using my func but this is almost identical to the example.

Required:

• I have searched past issues to see if this bug has already been reported.

Sorry for the time delay in replying since the last time. I checked mode of xcffib. You are right, the mode was 0. The fourth one is the output for the VM. It appears that the patch I wrote about here is still needed.

I’m also experiencing this issue. I’m looking to try out qtile, coming from bspwm (used for the last 3-4 years).

In my example, xrandr lists my monitor as following:

Monitors: 3
 0: +*DP-4 2560/598x1440/336+0+0  DP-4
 1: +DP-2 2560/598x1440/336+2560+0  DP-2
 2: +HDMI-0 1920/256x1080/144+5120+0  HDMI-0

while qtile swaps DP-2 and HDMI-0.

2022-08-02 16:20:29,185 WARNING libqtile hooks.py:<module>():L28 0 2560x1440+0+0
2022-08-02 16:20:29,185 WARNING libqtile hooks.py:<module>():L28 1 1920x1080+5120+0
2022-08-02 16:20:29,185 WARNING libqtile hooks.py:<module>():L28 2 2560x1440+2560+0

Since HDMI-0 is a monitor that occasionally is disconnected, this makes this issue quite tedious issue.

I find it a bit strange that qtile try to use monitor index from randr / xrandr instead of using monitor name (which are unique).
