Yes, as stated in the requirements section in the Readme, you need Linux to use gfxtablet. (Would be a good reason to give Fedora or Ubuntu a try 😉 )

you must do sudo modprobe uinput (uinput is a kernel module)

Just discovered this (great!) app. This suggestion would be great for using a normal tablet with fingers — now it acts as if I have the mouse button 1 down when I “draw”.
Even an optional bar in the bottom of the screen for pressing/releasing buttons would be awesome… I do not know how difficult it would be, but it would add a lot of flexibility to the app!
Thanks!

Hi, I love the app. But I’ll like the client app to be able to zoom in on the screen, so you can map small portion of the screen on the tablet. It helps in writing on white board and presentation.

I know OpenSSL, but I wouldn’t say that a secure solution with client-side certificates is “easy” (and without client certificates, every browser script that is allowed to connect to local sockets would still be able to do malicious things).

(If it is enough to click OK [no password required] to install a rootkit, it doesn’t matter if GfxTablet is present anway.)

So, thanks for your suggestion 🙂 But GfxTablet is a prototype/proof of concept and not intended to be a secure server that supports authentication. If you’re interested in implementing this, please fork and submit a patch request.

Did I show you what I’ve built with it? It is here. 😃 Not very useful
for mouse control as it appeared, but it is still fun to play with it.

For multiple desktops to control.

http://nmap.org/book/man-port-scanning-techniques.html - this page lists technique that allows to probe if a UDP post if closed. It would be awesome to see green button that lights up when you complete IP entry in configuration dialog.

The driver is a user-space driver and does not need “installation”, but it needs to be run. I don’t like it to be limited to one application, too, so I won’t make a GIMP user-space hack for this.

But it’s a cool idea and feel free to make it, the protocol specs are in “doc” directory.

Hello!

This tool is awesome!

I would like to know how far we would be from converting any Android device with touch screen to a handwriting input solution, especially for Chinese characters.
There is already a tool called Tegaki that integrates with ibus or scim and allows direct drawing (in a dedicated popup window).

Would it be possible to have a “Tegaki via Android”? I understand having feedback from the screen to the device would be a hassle, but just a drawing area with 3 buttons (validate, delete last stroke, reset).

Don’t execute networktablet.c, compile it first and then execute ./networktablet

I got them from the website, and one apk i downloaded from google play market on my htc evo 3d, tested it and it worked, then used adb pull to grab it and adb push to put it on the desired device.

I have note 2

you need to compile it for 32bits!

Now I can actually see where I’ve drawn!

Is this still an issue for you?

Awesome. Thanks.

Thanks, I will make a setting for it.

It was initially developed for use with Linux. Christoph contributed a windows driver in #34

I made some further tests and I think the problem I had yesterday is actually caused by two things:

(i) the WiFi connection was quite unstable yesterday. Thus with better WiFi I could not reproduce the “line-drawing-to-the-border” problem today.
(ii) the notification bar is still touchable and you can activate it accidentally.

While (i) is totally my fault, (ii) should probably be fixed. Maybe you can do it in the same way as it is done with the system’s video player, i.e., if the power button is pressed the touch interface is locked.

Best,

Michael
