Disabling WIFI and turning screen of during boot
Hi, I've got an old T410 that I'm trying to convert to a server. I've got it setup with Arch already.
It has SSH running as well as NetworkManager running to get IP through eth0.
During boot, wireless interface is turned on automatically and NM tries to manage it.
How do I disable it during boot? I can ssh into it and do `ip link set wlp3s0 down` but I want to do it automatically.
I also want to turn the LCD screen off or turn the brightness to minimum during boot.
Any idea how I can configure these?

Re: Disabling WIFI and turning screen of during boot
Do you want to ever use the wireless? If not then one option is to simply blacklist your wlan driver so the interface doesn't exist.
Similar question with the screen, do you want it off all the time or only during boot?

Re: Disabling WIFI and turning screen of during boot
Ideally I would like to turn it off by default. But have the option to turn it on if I need to debug it or access it directly.
I guess disabling it in Kernel level is not an option then?

Re: Disabling WIFI and turning screen of during boot
Nuke networkmanager and enable dhcpcd for the ethernet device: https://wiki.archlinux.org/index.php/Dhcpcd (use the dhcpcd@eth0.service)
The WiFi device should initially be down anyway (ie. it's rather fired up by nm, I guess)?
Edit, about backlight: https://wiki.archlinux.org/index.php/Ba … #Udev_rule
