Sorry, I overlooked this.

Please create a file “99-calibration.conf” in “/etc/X11/xorg.conf.d”:

sudo nano /etc/X11/xorg.conf.d/99-calibration.conf

with the following content:

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option  "Calibration"   "3945 233 3939 183"
        Option  "SwapAxes"      "1"

To save the file and close nano hit Ctrl+x, y and Enter.

Good morning from Italy … thanks for the great guide!
Now my touch works! : slight_smile:
How can I change the bad display resolution? it’s hard to read what’s written !!

This display only has a resolution of 480x320. Do you think the shown resolution is actually lower than that? Could you possibly post a picture of the display?

I guess that’s what to expect if the physical resolution is just 480x300.

Of course but why on this display whit same resolution there s difference?

Hm, I don’t have a 3.5 inch display with a resolution of 480x320 to compare but in the pictures everything looks normal to me. Maybe try out the classical UI theme.

Do you have a picture that shows the difference you are referring to?

i’m sorry … no! but if i want enlarge the font text into css where i can go?

I have no clue. I don’t tinker with the .css files, but you probably can get help in the thread Contemporary optimizations for small or large landscape displays where you already have posted.

Thenk you for help!

This is the resolution of i set 480x320px

Yes, doesn’t look nice. With your other 3.5 inch display it was looking better (when resolution was also set to 480x320)?

i think of yes… but other display has not HDMI and i installed this script.

What is the content of that script? Do you have a link?
