Hello Mike,
I'm trying to set-up a Raspberry Pi with the Official 7" TouchScreen to
run an LCD set-up on reboot.
I need to rotate the screen, easily done in the config.txt and the
doings are documented but I also need to scale the screen so that the application fits the screen. This is my problem and I cannot determine
how to accomplish it.
The command to scale the display from the console is
PI@RPi :~ S xrandr --output DSI-1 --scale 2x2
but I need to somehow run this at reboot.
Is there a command to do the same in the /boot/config.txt file ?
thanks, Mike
See below what I found in several years:
Rotate screen:
Modify: config.txt
<
http://elinux.org/R-Pi_configuration_file>
<
http://elinux.org/RPiconfig>
Add: display_rotate=1
for 90 degrees
or add: display_rotate=3
for 270 degrees
For TouchScreen getting working: <

C-Library: 'evdev-right-click-emulation'
Install and follow their instructions.
Then the right mouse click also works.

You can organize AutoStart here:
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
Add what you wanted to start automatic after every boot.
In my case I added:
@/usr/bin/opencpn
For AIS+ECDIS viewing charts and ships when sailing.
Good luck with this.
Henri.
