What is GfxTablet?
|
|
==================
|
|
|
|
GfxTablet shall make it possible to use your Android device (especially
|
|
tablets) like a graphics tablet.
|
|
|
|
It consists of two components:
|
|
|
|
* the GfxTablet Android app
|
|
* the input driver for your PC
|
|
|
|
The GfxTablet app sends motion and touch events via UDP to a specified host
|
|
on port 40118.
|
|
|
|
The input driver must be installed on your PC. It creates a virtual "network tablet"
|
|
on your PC that is controlled by your Android device.
|
|
|
|
So, you can use your Android tablet or smartphone to control the PC and,
|
|
for instance _use GIMP with your Android tablet as a graphics tablet_
|
|
(even pressure-sensitive, if your hardware supports it).

Features
|
|
--------
|
|
|
|
* Pressure sensitivity supported
|
|
* Size of canvas will be detected and sent to the client
|
|
* Option for ignoring events that are not triggered by a stylus pen:
|
|
so you can lay your hand on the tablet and draw with the pen.
|
|
|
|
|
|
Requirements
|
|
------------
|
|
|
|
* App: Any device with Android 4.0+ and touch screen
|
|
* Driver: Linux with uinput kernel module (included in modern versions of Fedora, Ubuntu etc.)
|
|
|
|
If you use Xorg (you probably do):
|
|
|
|
* Xorg-evdev module loaded and configured
|
|
Probably on by default, but if it doesn't work, you may need to activate the
|
|
module: see https://github.com/rfc2822/GfxTablet/issues/7#issuecomment-13338216

Installation
|
|
============
|
|
|
|
Github repository: http://github.com/rfc2822/GfxTablet
|
|
|
|
|
|
Part 1: uinput driver
|
|
---------------------
|
|
|
|
On your PC, either download one of these binaries (don't forget to `chmod a+x` it):
|
|
|
|
* [networktablet 64-bit, dynamically linked, tested with Fedora 18 and Ubuntu 12.10](https://github.com/rfc2822/GfxTablet/blob/binaries/networktablet-x86_64?raw=true)
|
|
|
|
or compile it yourself (don't be afraid, it's only one file)
|
|
|
|
1. Clone the repository:
|
|
`git clone git://github.com/rfc2822/GfxTablet.git`
|
|
2. Install gcc, make and linux kernel header includes (`kernel-headers` on Fedora)
|
|
3. `cd driver-uinput; make`
|
|
|
|
Then, run the binary. The driver runs in user-mode, so it doesn't need any special privileges.
|
|
However, it needs access to `/dev/uinput`. If your distribution doesn't create a group for
|
|
uinput access, you'll need to do it yourself or just run the driver as root:
|
|
|
|
`sudo ./networktablet`
|
|
|
|
Then you should see a status message saying the driver is ready. If you do `xinput list` in a separate
|
|
terminal, should show a "Network Tablet" device.
|
|
|
|
You can start and stop (Ctrl+C) the Network Tablet at any time, but please be aware that applications
|
|
which use the device may be confused by that and could crash.
|
|
|
|
`networktablet` will display a status line for every touch/motion event it receives.
|
|
|
|
|
|
Part 2: App
|
|
-----------
|
|
|
|
You can either
|
|
|
|
1. compile the app from the source code in the Git repository, or
|
|
2. [download it from the open-source market F-Droid](https://f-droid.org/repository/browse/?fdcategory=Multimedia&fdid=at.bitfire.gfxtablet) (**recommended**), or
|
|
3. [download it from Samsung Apps](http://apps.samsung.com/earth/topApps/topAppsDetail.as?productId=000000662994)
|
|
4. [download it from Google Play](https://play.google.com/store/apps/details?id=at.bitfire.gfxtablet)
|
|
|
|
After installing, enter your host IP in the Settings / Host name and it should be ready.
|
|
|
|
|
|
Part 3: Use it
|
|
--------------
|
|
|
|
Now you can use your tablet as an input device in every Linux application (including X.org
|
|
applications). For instance, when networktablet is running, GIMP should have a "Network Tablet"
|
|
entry in "Edit / Input Devices". Set its mode to "Screen" and it's ready to use.
