Hi, I just got myself a second screen which I daisy-chained with the first one, but I am having issues with getting screens to be identified properly. I use xrandr to configure display. The screens are identified as: $ xrandr DP-1-1-8 connected 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 59.95*+ ... DP-1-1-1-8 connected 2560x1440+2560+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 59.95*+ ... DP-1-1-1-1 disconnected (normal left inverted right x axis y axis) And I set the screen with: xrandr \ --output DP-1-1-1-8 --mode 2560x1440 --right-of DP-1-1-8 \ --output DP-1-1-8 --mode 2560x1440 \ --output eDP-1-1 --off I am reading in here that using Actions.Physical screens involves importing and changing the mapping(?). https://hackage.haskell.org/package/xmonad-contrib-0.14/docs/XMonad-Actions-... If I include only the import then nothing changes. The mappings don't compile for me. I am attaching the error below. Not sure, if I am doing something wrong or if the docs are incomplete. What is "W" meant to be?
