Android x86 and Touch Screen

Now this caused me no end of trouble! Hundreds of Google Searches, 2 evenings of trial and error, physically breaking my Touchscreen Ribbon Connector and repairing it.

Don't worry though! I have made the mistakes and taken the time, so now, I hope you don't have to! And you certainly do not have to break your touchscreen!

When I connected my Touchscreen via the USB, nothing much seemed to happen. I thought, at first, the driver for the touchscreen was not installed. When I looked more closely, on the lock screen, if I touched the screen I saw the circle generate waves, therefore my touches were being detected by android!

Upon closer inspection, I went to Settings -> Developer Options and enabled Touch Location. This puts a cross hair on the screen where it thinks you are touching.

For me, it was all messed up and took me ages to figure out the fix!

When I clicked the bottom left of the screen, the top right would register.
When I moved up the screen, the cursor would move to the left.
It appeared that the Axis were all messed up, like it had been Orientated by 90 degrees, but also inverted as well.

Here is the fix. (All commands are in the quotes and Linux is case sensative, so please copy exactly.

  1. Press Alt + F1 to go into Terminal mode. (Alt + F7 will switch back to the GUI)
  2. Type in (Without the Quotes) "stop zygote" and press enter (This will stop the Android GUI)
  3. Type in (Without the Quotes) "mkdir /data/system/tslib" and press enter (This should make a directory/folder called tslib inside /data/system
  4. Type in (Without the Quotes) "cd /data/system" and press enter (This will change the current directory to /data/system
  5. Type in (Without the Quotes) "ls" and press enter (This will list all files and folders in the current Directory)
  6. Check to see if your new directory, tslib is listed.
  7. Type in (Without the Quotes) "ts_calibrate" and press enter
  8. This should load up the calibration tool and you should have a X in the top left to press, when you do, you are moved to the top right, then bottom right, then bottom left and finally the centre of the screen.
  9. Type in (Without the Quotes) "cd tslib" and press enter (This should move you into your new tslib directory you made earlier)
  10. Type in (Without the Quotes) "ls" and press enter (You should see a file in there called pointercal, which was created by the calibration tool)
  11. Finally, type in (Without the Quotes) "start zygote" and press enter (This will load up the GUI again along with your new calibration settings)
You should now have a fully working touchscreen!

I hope this helps!

    Nevermind! Got it working, I think it failed the first time since I skipped stopping the GUI. :-)

      ts_calibrate is the command, and it should be built into the OS by default, so it should be found

      I have the same problem. I have installed android x86 on Intel PC (removed windows, so no VM). I can't seem to execute "stop" command. I had to manually create the "/data", "/data/system" and "/data/system/tslib" folder structures. offcourse ts_calibrate is also an unknown command to it. Please help.

    This is a very, very helpful post! Thanks so much for this one. It would take someone so long to figure out these solutions or maybe even not at all. It would also be hard to find on Google.

    Hi!
    In my case, It doesn't actially save the new ts_calibrate settings.
    It is still inverted.
    I also tried to calibrate them opposite, but it is still inverted as beginning.
    What can it be?
    Is it because I am on emulation starting from sdcard? must I install in on harddisk so to have correct files saving on harddrive, or what?
    Thank you all

      I'm having the same issue at Steve.
      My X and Y axis are swaped even after running through the calibration.
      I'm using the touch screen here:
      http://www.ebay.com/itm/2DIN-IN-DASH-7-Samsung-HDMI-Touch-Screen-Monitor-KIT-USB-SD-Raspberry-Pi-/121002169460

      Does anyone have any information on this? Is this a hardware issue and the only solution is to find a different touch screen?

      Thanks in advance!

      And thanks to Jon for showing how to access the calibration utility!

    hi,
    it works with a eGalax TS with android-x86 4.4
    !!BUT!!
    you have 2 chmod the tslib folder and the pointercal file, if it does _not_ work after
    calibrating ;)

    type: chmod 777 /data/system/tslib
    type: chmod 777 /data/system/tslib/pointercal

    cheers Felix

    In 4.4.2 the file pointercal is in /data/misc/tslib All the other is the same.

    2023 and still an issue. (I'm not impressed with Android-x86 at all). In the several threads around the internet on this issue, respondents keep ignoring the fact that the posters keep saying there IS NO ts_calibrate. CHMOD on some directory you just created has nothing to do with ts_calibrate not being on the filesystem, or at least not in the path.
