Recently purchased a new combo wireless and Bluetooth multimedia keyboard for use with my Raspberry Pi 4.
Love the new keyboard, but sadly, even after adjusting the mouse pointer speed to the Max Speed under Preferences / Keyboard and Mouse it is still too slow for my sanity.
Luckily, their is another way to increase the mouse speed.
The following Terminal command will open up the necessary file to edit:
sudo nano /boot/cmdline.txt
Append the following text to the end of the line:
This is not the default setting because it requires more CPU cycles and is only required for some keyboard/mouse combos.
I welcome your thoughts, questions or suggestions on my article on Mouse Pointer Speed on Raspberry Pi 4.
Let me know if you found any errors within my article or if I may further assist you by answering any additional questions you may have.
