[SOLVED] Touch not working correct

[felix1024]

Look in the file /home/pi/.xinitrc

Below is the command used to determine the screen size. Maybe it's not detecting the correct height?

Code:

# Capture screen size
SCREENSIZE="$(fbset -s | awk '$1 == "geometry" { print $2","$3 }')"

Hi Tim

yes, there seem to be the problem because fset does not return the expected values. In my pi4 raspian lite with chromium kiosk mode setup values gives:

Code:

$ fbset -s

mode "400x1280"
   geometry 400 1280 400 1280 16
   timings 0 0 0 0 0 0 0
   accel true
   rgba 5/11,6/5,5/0,0/0
endmode

while in moode it gives:

Code:

$ fbset -s

mode "400x480"
   geometry 400 480 640 1280 16
   timings 0 0 0 0 0 0 0
   accel true
   rgba 5/11,6/5,5/0,0/0
endmode

and therefore to make chromium work in landscape with 1280 x 400 one needs to change .xinitrc as suggested by forum members to

Code:

# Capture screen size
#SCREENSIZE="$(fbset -s | awk '$1 == "geometry" { print $2","$3 }')"
SCREENSIZE="1280,400"

view port reports correct 1279 x 399
