Please set up RandR 1.5 monitors automatically as per the TILE properties

Description

Created attachment 135557 xrandr --props

I use X.Org 1.19.3 on Linux.

I use a Dell UP2414Q monitor, which exposes two outputs via Multi-Stream Transport (MST). I verified this issue is also present when using a display requiring multiple connections, e.g. the Dell UP3218K, which uses 2 DisplayPort connections.

When starting Xorg, the position of the individual outputs relative to each other is the wrong way around: instead of (left half, right half), I see (right half, left half) on my monitor.

Also, when using xrandr --listmonitors, I see 2 monitors instead of 1.

To fix this, I currently use the following in my ~/.xsession:

xrandr --output DP-5.8 --auto --right-of DP-5.9 xrandr --setmonitor up2414q auto DP-5.8,DP-5.9

I think it would be better if Xorg (specifically the RANDR extension, I suppose?) would look at the TILE property, arrange the outputs accordingly and create a monitor object accordingly.

I attached the output of xrandr --props.

Please let me know if you need any further details.

Thanks!
