7" Touchscreen Calibration for Raspi running Venus

Hi! I have conected a 7" HDMI touchscren display to my Raspi runing Venus OS, GUIMods / RpiDysplaySetup.

The display is fine, I can see that its responsive to touch but completely uncalibrated, unusable.

The RpiDysplaySetup reedme file says I should run ts_calibrate, which I'm attempting to do from root directory using Putty. Its not working, I suppose I have to disable GUI first.

So I run:

root@raspberrypi2:~# mv /etc/venus/headless.off /etc/venus/headless

And I get:

mv: can't rename '/etc/venus/headless.off': No such file or directory

Its not working. I don't have much programing knowledge. Any suggestion?

The problem you are having with the mv command is there is probably no headless.off file.

Some people enable the GUI by using mv /etc/venus/headless to mv /etc/venus/headless.off but actually there's nothing in either of these files. The presence of ...headless simply instructs the gui startup script to skip the local GUI.

All you really need to do to disable the local GUI is to create an empty headless file:

touch /etc/venus/headless

Then when you want to reenable the local GUI use

rm -f /etc/venus/headless

If you have the latest version of RpiDisplaySetup, you can run ts_calibrate from it's setup script.

/data/RpiDisplaySetup/setup

Then select calibrate from the menu and follow the instructions.

RpiDisplaySetup will install ts_calibrate if it isn't on the system before it runs it but your PI needs to be connected to the internet.
