I've got a cablematters thunderbolt hub with two DP outputs connected to two LG monitors. They aren't exactly the same but it doesn't matter, as I'm using Xorg, which doesn't use EDID for layouts. It just uses the output names, which are DP-1, and DP-2, and sometimes the hub flips them. The only way I've found to "fix" this is to use Autorandr, which will update the layout based on the EDID, but the output names remain flipped. This is still an unsolved problem, because i3 uses the output name rather than physical position for where to put workspaces.
My other laptop doesn't have an nVidia GPU and runs Sway/Wayland, which doesn't seem to have this issue.
If anyone knows how to solve this I'd be eternally grateful. It's been driving me nuts for a year.
- pedrocr 4y agoIf you switch from i3 to sway you can use the serial number instead of the port to assign outputs. I think these days it's usable with even the proprietary nVidia driver.
- colordrops 4y agoOh interesting, I understand that sway with Nvidia is developing quickly. I did read maybe less than a month ago though that it's still quite glitchy. Will look into it again.
