very basic, you’ve bought the wrong screen in combination with the hardware and operating system. Volumio is a headless (no monitor, no keyboard, no mouse) console application.
See it like this. You bought yourself a boat (screen) while you live in the desert. (hardware/OS). Both are fine, but you won’t be able to sail.
Sort out which command gives you the correct output. Make sure if the first doesn’t give you the desired result, always perform sudo xrandr -d :0 -o normal first, before running the next command.
90 deg sudo xrandr -d :0 -o right
180 deg sudo xrandr -d :0 -o inverted
270 deg sudo xrandr -d :0 -o left
0 deg sudo xrandr -d :0 -o normal
then execute the following command:
sudo nano /etc/X11/Xsession.d/45custom_xrandr-settings
copy the command that gave the correct result from above test
wtf,…
I have to admit I did a fresh install today as I tweaked to much settings, loading a desktop over volumio. for what ever reason, the command don’t error out. Even the command sudo xrandr --display :0 --query, didn’t work yesterday.
And we didn’t get to the rotate part yesterday, first tried to get info on what was connected where, in case we needed to make a xorg.conf.
No thank you, I’ll stick to reading once-in-a-while and comment only when it might be useful
Wrong screen size to judge properly
On a serious note: there is a CAPPEDRES parameter in /opt/volumiokiosk.sh (and the corresponding handling of it), which could perhaps be used for a custom screen size.
I introduced and tested it to reduce a macbook screen to 1920x1080, it can also be used to limit a 4K TV screen for it to become reasonable.
Whether this will also work with this 1980x480 screen to avoid sort of warped images?? Worth a try.
Just my my last 2 cents worth, problem appears to be solved.
