rotate lcd screen and touch about lcd-show

[sarah278]

For the 3.5 TFT following change to /etc/X11/xorg.conf.d/99-calibration.conf did the job:

After
Option "SwapAxes" "1"
insert
Option "InvertX" "1"
Option "InvertY" "1"

I have done this but my touch is still not rotated.

I changed boot/config.txt
dtoverlay=tft35a:rotate=90

(Although, the screen has always been landscape so this seemed unecessary, or there is other config)

I edited the calibration files and did all three of the above, and variations on them but the touch is always the same, x=y y=x.

I ran xinput_calibrator, it has these settings
Option "SwapXY" "1" # unless it was already set to 1
Option "InvertX" "0" # unless it was already set
Option "InvertY" "0" # unless it was already set
Slightly different again, but as this is the latest driver and package Id expect this and changes to this to work, but that doesnt either.

Is there something else t check or set ?

Ok I found a document that seems t work for anyone else with this problem
