Please verify that you have Network Manager 1.16 and wpa_supplicant with P2P wifi support.
[0] % pacman -Q networkmanager wpa_supplicant
networkmanager 1.18.0-1
wpa_supplicant 2:2.8-1
How do I verify the latter?
As a note, I can get Miraclecast to work to the point of connecting to the device.
You could check nmcli and see if you have a p2p-dev-XXX device where XXX is the name of your normal wifi device.
Or run gdbus call --system --dest fi.w1.wpa_supplicant1 --object-path /fi/w1/wpa_supplicant1 --method org.freedesktop.DBus.Properties.Get fi.w1.wpa_supplicant1 Capabilities as root and see if p2p is in the list
p2p-dev-wlp0s20u1: disconnected
"p2p-dev-wlp0s20u1"
So that'd be yes.
Does NetworkManager need to be running for Screencast to work? I just tried starting it and trying again and I still didn't get anything, but I normally use systemd-networkd.
EDIT: Tried on my laptop which uses NM for a manager by default, and I could get it working. Got stuck on x264 though.
Hmm, really not sure what might be going on. Could you paste the output of iw phy please?
Oh, right. You Wi-Fi needs to be managed by network manager for this to work. If you do something weird like starting network manager, allowing it to manage your main wifi connection but also managing it otherwise, then this will probably simply not work.
Thinking the main issue was something odd happening with NetworkManager. Feel free to re-open, but I don't really see anything I can do here right now.
Ah yeah, forgot to close this one, sorry. It was me not understanding I need to use NM for this project to work.
