Guile-based xbindkeys config file to rebind mouse shoulder buttons + scroll wheel
Xbindkeys remapping does not work on Ubuntu's new display protocol Waland. To check if you need to switch to Xorg, run echo $XDG_SESSION_TYPE.
You'll need xdotool and xbindkeys with -guile support compiled for this to work (The Ubuntu xbindkeys will have this support by default).
Use xbindkeys --defaults-guile > $HOME/.xbindkeysrc.scm to generate a default config file in your home folder, which will be used by xbindkeys, and paste the contents of own config file as you wish.
After any modification of this file, use killall xbindkeys && xbindkeys to reload with new bindings.
To add new bindings, you can use xev and xbindkeys -k to find what are the buttons/keys your want to bind.
If you want mouse wheel or other to change screen brightness using ddcutil (for example if you are using an external second screen with a laptop ; can't be monitored with gdbus) you will need to set things up so that you can use it without sudo:
- install ddcutil
sudo apt install ddcutil
- Manually load kernel module i2c-dev
modprobe i2c-dev
- Verify that your monitor supports brightness control
sudo ddcutil capabilities | grep "Feature: 10"
- udev rule for giving group i2c RW permission on the /dev/i2c devices
sudo cp /usr/share/ddcutil/data/45-ddcutil-i2c.rules /etc/udev/rules.d
- Create i2c group and add yourself
sudo groupadd --system i2c
sudo usermod $USER -aG i2c
- load i2c-dev automatically (needs root access)
touch /etc/modules-load.d/i2c.conf
echo "i2c-dev" >> /etc/modules-load.d/i2c.conf
- Reboot for changes to take effect
sudo reboot
This tool uses ddcutil as backend, so first make sure that your user can use use following shell commands without root or sudo.
ddcutil getvcp 10 to check the brightness of a monitor and
ddcutil setvcp 10 100 to set the brightness to 100
It automatically supports multiple displays detected by ddcutil detect
As you might notice, setcvp may be quite slow.
To accelerate you might use --async option for multithreading and --noverify option once you are sure what you are doing.
The main slowing issue is the implicit call of detect, so you may want to note the bus number of the screen as illustrated below:
Display 1
I2C bus: /dev/i2c-19 <--- HERE
EDID synopsis:
Mfg id: AAA
Model: AAAA P1234
Product code: 12345
Serial number: ABCD123
Binary serial number: 123456789 (0x075bcd15)
Manufacture year: 1917, Week: 42
VCP version: 2.1
Then specifying --bus 19 will override the implicit detect call and speed things up.
