For auto-starting I create a shell script on the desktop called startup.sh. No telling what I've done following the commands for. sudo apt-get update & sudo apt-get install gluqlo. sudo apt-add-repository ppa:alexanderk23/ppa.

The screen blanking problem was the easiest. I'd like it to do a dissolve/fade from one image to the next. I wanted it to auto-start with no need for keyboard and mouse. And you'll need to do this after Venus OS updates and also after package updates.Great instructable - thanks! There were three changes I really wanted to make, and I've sorted two of them out so far. So if you do need to modify the file, do it after package install. A screensaver for Raspberry Pi that shows temperature with updates to a tutorial from liberato. So in this case cp/opt/victronenergy/gui/start-gui.sh /opt/victronenergy/gui/start-gui.sh.origĪlso note that installing a package will overwrite the current file and any modifications you make manually will be lost.

You can modify files manually but should copy the original file to a file with a. Do NOT use the stored backup of v2.89 as it will still contain the changed file.

You also need this line in /u-boot/config.txt in order for the display to enter a power-down state. So you can't blank two displays if they are both hooked up.
