Input, Audio, and Clipboard

Wacom Tablet

Pressure-sensitive drawing tablets are supported:

• Pressure -- full pressure range is forwarded
• Tilt -- pen tilt data is forwarded for supported tablets
• Works with applications like Krita, GIMP, Blender, and other pressure-aware software

No additional configuration is needed. The agent creates a virtual tablet device when tablet input is received.

Gamepad

Xbox-compatible gamepad input is forwarded from the viewer to the agent:

• Button presses, analog sticks, and triggers
• Works with games and applications that support standard gamepad input
• The viewer must have a gamepad connected locally

Audio

Audio from the remote machine is streamed to the viewer automatically if a sound server is running.

Supported sound servers:

• PipeWire (default on modern distros)
• PulseAudio

By default, the agent tries native PipeWire audio first. On known-bad Rocky 9 / PipeWire combinations, auto mode can degrade to parec because that path is stable for the same stereo Opus stream. To force a backend for diagnosis, set VDO_AUDIO_MODE to native, pw-record, or parec and restart vdo-agent.

If audio is not working, check that one of these is running:

# Check PipeWire
systemctl --user status pipewire

# Check PulseAudio
systemctl --user status pulseaudio

Clipboard

Bidirectional clipboard sharing allows copy/paste between the viewer and the remote machine.

Requirements:

• xclip must be installed for X11 sessions

Install it if missing:

# Rocky / Fedora
sudo dnf install xclip

# Ubuntu
sudo apt install xclip

Once installed, Ctrl+C / Ctrl+V works across the connection just like a local clipboard.

Troubleshooting Input Issues

If keyboard or mouse is not responding:

1. Check that the agent is running: systemctl --user status vdo-agent
2. Restart the agent: systemctl --user restart vdo-agent
3. Ensure permissions were set up correctly by re-running the installer
