UInput Access Setup

Creating virtual input devices requires /dev/uinput to exist and be writable by the current user.

Group setup

Create a uinput group:
bash
```
sudo groupadd --system uinput
```
Add your user to it:
bash
```
sudo usermod -aG uinput "$USER"
```

Udev setup

Create a udev rule:

bash

echo 'KERNEL=="uinput", GROUP="uinput", MODE="0660",' \
  'OPTIONS+="static_node=uinput"' \
  | sudo tee /etc/udev/rules.d/99-uinput.rules

Load the kernel module:
bash
```
sudo modprobe uinput
```

Reload udev rules:

bash

sudo udevadm control --reload-rules
sudo udevadm trigger

Start a new login session, or refresh the current shell group list:
bash
```
newgrp uinput
```
TIP
Logging out and back in is the cleanest way to pick up the new group.

Verify

Confirm the node exists and the group is correct:
bash
```
ls -l /dev/uinput
```

Expected shape:
