i3 problems after Ubuntu upgrade

I think most of my issues are Ubuntu dependency changes making i3 break.

I think that Ubuntu 2024 doesn’t use X11 anymore so certain things can’t be controlled in gnome like I used to.

Pulseaudio is no more, it seems, so my volume and media controls are dead and I have to use amixer commands instead.

Keyboard backlight toggle button isn’t working.

i3lock is suddenly working again on suspend… I haven’t seen that lock screen in years… I thought the system had crashed.

The keyboard layout was setting to US on every boot. Despite /etc/default/keyboard being set correctly and having “setxkbmap -layout uk” in my i3 config.

Turns out “ibus” was running on login and overwriting both. I had to run ibus-setup and add the keyboard layout in its gui.
