Live mode

The so-called Live mode makes a smartpad behave like a bluetooth-connected normal graphics tablet. Stylus input is immediately transmitted to the host computer and the tablet can thus used for digital drawings or as a mouse replacement.

It is possible to use live mode with tuhi. However, this is an experimental feature and not shipped in the flatpak. Users need the git repository for live mode:

git clone https://github.com/tuhiproject/tuhi.git
cd tuhi
sudo ./tools/tuhi-live.py

tuhi-live must run as root to create the required /dev/hidraw device. This device will appear as virtual input device, libinput or other userspace input stacks will then handle that device as if it was any other input device.

Note that live mode is an experimental feature and the user interface is raw. To use tuhi-live, you must register the device first. Start Tuhi normally and follow the instructions to register the device.

Troubleshooting

Tuhi 0.2 had known issues with live mode, please use 0.3 or later.

Authorization errors

An authorization error means the device is not registered with Tuhi:

11:44:38 ERROR: tuhi.wacom: **** Exception: DeviceError.AUTHORIZATION_ERROR ****

Please start Tuhi and follow the registration instructions. Note that you must register Tuhi "normally", i.e. do not use the flatpak to register Tuhi. Flatpaks store the configuration files in different directories.

Something else doesn't work

Keep trying. Sometimes, it doesn't work on the first attempt (yes, that's a bug, but hard to reproduce and fix).
