[Question] - Orangepi5b arm64 - failed to create virtual keyboard device: could not open device file

[dinbtechit]

Hi, I am trying to run this on organipi5b arm64, followed the steps from readme.

My go version is - go version go1.20.5 linux/arm64

Build from source

git clone https://github.com/mafredri/magic4linux.git
cd magic4linux/cmd/magic4linux 
GOOS=linux GOARCH=arm64 go build

Output:

Running the app

╭─orangepi@orangepi5b in ~/Downloads/magic4linux/cmd/magic4linux on main ✔ (origin/main)
╰$ ./magic4linux   
panic: failed to create virtual keyboard device: could not open device file

goroutine 1 [running]:
main.main()
	/home/orangepi/Downloads/magic4linux/cmd/magic4linux/main.go:28 +0xd8

Any idea what I could be missing? Also I wonder if I should pass in the ip address of my TV or anything? Any advice is massively appreciated.!

I seems you're trying to run it as non-root, so my guess is that /dev/uinput permissions are lacking. There's a link in the readme for how to fix this.

Also I wonder if I should pass in the ip address of my TV or anything?

As long as your orangepi and TV are on the same network, they should be able to find each other just fine, so no IPs are necessary (or supported for that matter 😅).

Hope this helps.

@mafredri - Thank you so much mate! That solved the problem!!!! I no longer see that error.

Here are the steps that I had to run: (I did this step earlier but looks like I had a typo in my command when I copy pasted it)

echo KERNEL==\"uinput\", GROUP=\"$USER\", MODE:=\"0660\" | sudo tee /etc/udev/rules.d/99-$USER.rules
sudo udevadm trigger
reboot

However, the magic remote does not seem to be working. Also not seeing anything in the logs. Do you have any suggestions there?

1. I have the magic4pc server installed on my TV
   

2. and have ./magic4linux running in vscode
