Automatic screen layout switching

TODO Resolution is wrong when switching back to default via autorandr --batch --change.

Install and configure autorandr

pacman -S autorandr
... # undock and configure undocked layout
autorandr --save default
... # dock and configure docked layout
autorandr --save docked

Setup udev rule

# /etc/udev/rules.d/50-dock.rules
ACTION=="change", BUS="usb", ATTRS{idVendor}=="17ef", ATTRS{idProduct}=="3082", NAME="dock", RUN="autorandr --batch --change"

Note that I used device 17ef:3082 but it could be any of

Bus 006 Device 004: ID 17ef:3082 Lenovo
Bus 006 Device 003: ID 17ef:307f Lenovo USB3.1 Hub
Bus 006 Device 002: ID 17ef:307f Lenovo USB3.1 Hub
Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 005 Device 007: ID 2109:8818 VIA Labs, Inc.
Bus 005 Device 010: ID 2109:8818 VIA Labs, Inc.
Bus 005 Device 009: ID 17ef:3083 Lenovo
Bus 005 Device 006: ID 17ef:3081 Lenovo
Bus 005 Device 003: ID 17ef:3080 Lenovo
Bus 005 Device 002: ID 17ef:3080 Lenovo USB2.0 Hub
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Reload rules.

udevadm control --reload-rules

TODO xrandr seems to be triggered by something else. Auto config switching still works after disabling udev rule. I am truly puzzled.

Tablet mode

See this other post.

UI

i3

# resize large floating windows
for_window [window_role="GtkFileChooserDialog"] resize set 1920 1440 # 4K
for_window [window_role="GtkFileChooserDialog"] resize set 1440 960  # 2.5K

Troubleshooting

External screens and autodock

If using external screens via dock, autorandr, and udev rules, use compatible resolution, e.g. 2560x1440 with Xft.dpi: 144.

Undocking does not properly roll back to the max resolution 3840x2160 (maybe because autorandr is called from outside X session? bug?).

Then configure various resolutions with autorandr then create a file /etc/X11/xinit/xinitrc.d/10-autorandr.sh with the following contents

#!/bin/sh
[ -x /usr/bin/autorandr ] && /usr/bin/autorandr --change

And make it executable

chmod a+x /etc/X11/xinit/xinitrc.d/10-autorandr.sh

See this gist.
