Sorry no HDMI as I only have VGA output from PC. 10" is a bit to small I think.

Have been playing around with the display, in Win no luck but suddenly it is alive here in Linux.

All backwards and needs to be calibrated, so how do I do it now as earlier attempt to install the calibrator was unsuccessful.

Any ideas what to do?

Cheers
Bengt

The answer is probably hidden in this discussion:
sourceforge.net/p/emc/mailman/emc-users/...ail.com/#msg35818192

But you basically need an xorg.conf and then experiment with numbers.

Managed to download the xinput_calibrator-0.7.5.tar.gz. It is now in my dowloads.

How do I proceed from here? Please remember I am totally noob to this.

I have managed to install and run calibrator, but no /etc/X11/xorg.conf.d/99-calibration.conf to be found.

No such directory under X11

You would need to create the directory.

If you don't have a file called xorg.conf either, then you can just create the file and put the info in there.

sudo nano /etc/X11/xorg.conf

shift-ctrl-V

ctrl-X

Y - enter

Before your answer I did restart and now the numbers are way off the chart.

I have my old numbers ( acceptable precision ) in the file but still way off so nothing works.
Obviously numbers are stored somewhere, but what files to delete?

I think xinput-calibrator fails to consider the existing numbers, so if you already have an xorg.conf and re-run it, the new numbers are really very wrong.

I ended up just figuring out the numbers by trial-and-error, editing xorg.conf directly.

It's a lot of reboots, but bearable.

There is almost certainly a way to restart X, but I don't know it.
