Only works for DeepinOS! Might work on other distros too, but it might also eat your cat.
Small patch for linux keyboards.
Adds german umlauts (ä, ö, ü, ß) to US-Keyboards.
Patch itself by SplittyDev, Scriptfile by myself.
git clone [email protected]:Severon96/us_keyboard_patch.git
cd us_keyboard_patch
sudo bash ./us_keyboard_patch.shJust run the script with root privileges, login again and switch to the US-Keyboard.
You can also switch to a different keyboard layout and back to US to make it work without having to log out.
