I am using Raspbian Jessie Lite and I want to display a website in iceweasel kiosk mode.
To realise this I created an
.xsession file which gets executed when booting.
When the website displayes a black border is shown, too.
In the /boot/config.txt I uncommented the
disable_overscan=1 part. But it gets ignored.
If I try to config the
... part in negative values it gets ignored, too.
Why are my settings in the config file ignored? And how can I fix this?
