rotating the screen doesn't work

AnduriI

Hey there,

it’s been quite a while since I installed my MM.
Now there was the time for an upgrade of the monitor and I decided to do it with a freshly installed pi to start fresh. That worked fine and I got it running very soon. Only problem is the rotation of the screen:
As far as I know the old methom with boot/config.txt doesn’t work anymore, but I have to use xrandr.
I can use DISPLAY=:0 xrandr --output HDMI-1 --rotate right in console to rotate, but when using @xrandr --output HDMI-1 --rotate right in /etc/xdg/lxsession/LXDE-pi/autostart it has no effect.
What is to now correct way of doing it?

Thanks a lot in advance,
Anduril

well the problem was I think about privileges to issue the xrandr command from a shell. I got it worked out with xhost + and it works fine now. Thanks a lot for your help.

@AnduriI

you can change this in the raspian os gui somewhere in the menu.

You might want to read this which comes from the official Raspberry Pi site.
