The goal is to have my screen rotate to normal and start Barrier (keyboard and mouse share software) on boot up.

So, i have a laptop laying on top of my desktop monitor that i use kinda like a second monitor. But it boots up with the display sideways and i have to login to be able to use mouse and keyboard from my desktop.

I have tried everything to get a systemd service to handle those problems. But no luck, i think the service isnt running properly on boot. Please help me out.

Let me know if there is a better community to post to or if additional info is needed. Thanks.
