[SOLVED] Touch not working correct

[Tim Curtis]

Got it.

I'll add a "Screen size" option to the Local Display section to allow automatic detection to be overridden.

Well while doing further tests and comparing with the pi4 install it seems that the fbset difference has nothing to do with the touch anomaly.

I tested this change in .xinitrc without any improvement in touch behaviour:

Code:

fbset --geometry 400 1280 400 1280 16

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

note the inversion of params in awk statement

now screen is as before but touch still misbehaving
although fbset -s now gives expected values: (exactly the same as on the pi4 lite install)

Code:

felix@moode:~ $ 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

I compared installed X11 packets, but could not find differences. Looking further...

Interesting. I'll hold off until the root cause is identified.
