I have tried different softwares for drawing using my touchscreen (e.g. Gimp or Krita). However, when I touch and drag (to draw a line) what happens is that only the mouse pointer moves from one place to the other, but as I was not "clicking" to draw.

I also cannot use some gestures such as zooming a picture.

I have installed Touchegg, but I'm not sure how to use it and if it can help me solve this problem.

  • While this may not be applicable to your specific touch screen, I used the Gimp with a Thinkpad X60 tablet, which utilizes a stylus, and this worked fine for drawing. Commented Jul 12, 2016 at 13:00
  • @Dev Thank you, but that's not really a solution to the problem... The touchscreen should work as well as in Windows, and it doesn't. Commented Jul 16, 2016 at 0:06
  • @cinico It is a temporary solution until you can find a real solution. Commented Jul 16, 2016 at 4:28

First install touchegg:

sudo apt-get install touchegg

Install the dependencies for the GUI tool (for TouchEgg) using this command

sudo apt-get install build-essential libqt4-dev libx11-6 libx11-dev

Download the GUI touchegg-gce from GitHub. Then:

  1. Change to the directory holding the .zip file.
  2. Issue the command unzip Touchegg-gce-master.zip to extract the file.
  3. Change into the Touchegg-gce-master folder.
  4. Issue the command qmake
  5. Issue the command make
  6. Copy the touchegg-gce file to /usr/bin

Under "Touchegg" it shows you how to configure the program, maybe this'll allow you to draw on your touchscreen. I am sorry I am unable to help further as I don't know much about this program.

  • Thank you. I was able to install touchegg, as I mentioned. But it is the problem on configuring it correctly that I couldn't solve because I think I did everything correctly, but still can't draw I as explained... Commented Jul 18, 2016 at 17:46
  • Assuming you completed the 6th step, open Touchegg and click "Add", I'm guessing you'll be drawing with one finger so in the Dialog I'd make Fingers: 1, Gesture: hold, Direction: up (but you'll have to make this same motion configuration 4 times for all the directions, and more for diagonals if possible) Action: drag(?) I'm sorry, I would love to test this out but can't; I wanted to try to help seeing as no one else offered a solution. Its worth trying. You could also try changing the Action to "click" and whatnot and see if it works as should. Commented Jul 20, 2016 at 6:12

A workaround is to hold down the mouse button while drawing. This gives you the advantage of not clicking accidentally when bumping the screen for example.

    He's using fingers on a touchscreen, not a mouse. Why use a mouse on a touchscreen? Commented Jul 12, 2016 at 16:53
  • @ipselute I know, I'm just saying hold your mouse button down while you're using fingers on the touchscreen. Commented Jul 12, 2016 at 16:54

    That's a good one!!! Ha, ha, ha! Just use a cheap mouse instead of an expensive touchscreen! Point taken. Akiva used a stylus that worked, i guess it's a problem of touch sensitivity threshold. Commented Jul 12, 2016 at 17:02
