Keyboard backlight controls workaround for gnome + maintaining same level of backlight across suspend and reboots (all in one because everything is related here)

installing python library

pacman -S python-pydbus

preparations

change /home/user everywhere to the path where this folder is in

standalone Gnome fix

mkdir -p ~/.config/systemd/user/

place that file to this path

~/.config/systemd/user/gnome-dbus-fix.service

enable

systemctl --user enable gnome-dbus-fix.service
systemctl --user restart gnome-dbus-fix.service
systemctl --user status gnome-dbus-fix.service

After this your keyboard backlight gonna work regardless of whether gnome controls work or got bugged out

Unfucking touchbar on boot unconditionally

(Only works with old apple-touchbar driver, NOT tiny-dfr)

place the file

/etc/systemd/system/touchbar-poke.service

execute as root

sudo su
systemctl enable touchbar-poke.service
systemctl restart touchbar-poke.service
systemctl status touchbar-poke.service

You should see your touchbar reload, now this service gonna start every boot. Your kbd brightness will stay same across reboot. If you want brightness to not persist across reboot then change backup file from /home/user/.kbdbl to /tmp/.kbdbl

Unfucking touchbar on suspend + restoring keyboard brightness state

this is just upgraded suspend-fix-t2.service that also reloads touchbar correctly (tested on MBP 2019 16,1 and archlinux) and restores kbd brightness

place the file

/etc/systemd/system/suspend-fix-t2.service

execute as root

sudo su
systemctl enable suspend-fix-t2.service
systemctl restart suspend-fix-t2.service
systemctl status suspend-fix-t2.service

now try suspend and see its working
