Any suggestions?

Did you install miraclecast?

That conf file should be present on /etc/dbus-1/systemd

Here config for meson:

https://github.com/albfan/miraclecast/blob/master/res/meson.build#L3

See by default all build systems install on /use/local, I've updated build instructions to avoid that: See https://github.com/albfan/miraclecast/wiki/Building

jiapei100 · 2018-11-03T21:54:15Z

@albfan

Yup... I had miraclecast successfully installed using cmake, almost the same instruction as https://github.com/albfan/miraclecast/wiki/Building, but installed under folder /usr/local .

albfan · 2018-11-03T22:06:08Z

upload here the logs for support described in FAQ on this wiki. There's some problem with your run of miracle-wifid

What's sink and peer?
I'm expecting to display the my laptop's screen (running Ubuntu) directly on a Wifi projector. So, is my laptop running Ubuntu a sink or peer?

albfan · 2018-11-04T07:43:32Z

in miracast protocol your device can act as source (share a video stream (normally from its screen)) or as sink( receives and shows a video streaming). Both are peers for miracast

To try to use miraclecast as source you should look into #4 and #172 (which is still a WIP) continue this in those issues please

lianzhidong · 2018-12-19T07:47:27Z

I think you forget to copy the res/org.freedesktop.miracle.conf to /etc/dbus-1/system.d/.

dnapier · 2018-12-19T17:09:52Z

I'm seeing the exact same issue using the AUR from Arch Linux. Should I upload my logs as well? And if so, do you want me to create a new issue or append to this one?

albfan · 2018-12-19T20:45:18Z

@dnapier you can upload here

codeman101 · 2019-04-27T06:13:34Z

I have same issue with the AUR package. What logs do you need from me? The error occurs when trying to do this

$ sudo miracle-sinkctl for sink

or this

$ sudo miracle-wifictl

For peer. Given the difference between sink and peer described above I'ld like to do peer but I can't do either.

albfan · 2019-04-27T08:49:25Z

@codeman101. Not sure what happens Download the package with:

yaourt -G miraclecast-git
cd miraclecast-git
makepkg -sf

And upload the build (tar.gz) here so I can inspect

codeman101 · 2019-04-27T22:56:46Z

@albfan I don't use youart that aur helper has been deprieciated on Arch. I use yay which does it all. The only command I had to run run was yay miraclecast I just tried uploading the tar.gz file that the helper creates but github is saying it doesn't support uploading it. (the file type)

I could make a temporary repo to upload it to but I'd rather not if possible. Is there any way you can make a quick VM of Manjaro and run the command to see the tar.gz for yourself? You would just need to install yay which is done via sudo pacman -S yay You could grab the xfce iso it has a graphical installer so it won't take long to get up and running and xfce is very lightweight.

codeman101 · 2019-04-28T17:43:33Z

Here I made a temp repo to upload it. https://github.com/codeman101/temporary-for-data-transfer. I didn't do this originally because I thought gihub would get angry because of the size of the file is.

albfan · 2019-04-30T16:15:12Z

Thanks. AUR package seems correct. (it installs the dbus file)

org.freedesktop.miracle.wifi service is provided by miracle-wifid daemon:

You can check with:

dbus-send --system --dest=org.freedesktop.DBus --type=method_call --print-reply /org/freedesktop/DBus org.freedesktop.DBus.ListNames

Only if daemon is running you will see the service avaliable, so after run miracle-wifid in other terminal service should be avaliable, or in a oneliner:

sudo miracle-wifid & dbus-send --system --dest=org.freedesktop.DBus --type=method_call --print-reply /org/freedesktop/DBus org.freedesktop.DBus.ListNames | grep miracle
string "org.freedesktop.miracle.wifi"

codeman101 · 2019-04-30T21:55:21Z

That was it the instructions in the readme don't trigger the daemon but that second line you wrote in that post did it. Please consider making the following edits to your readme

Add that line or something else to force the daemon to trigger.
Make it more clear as to what to do when you say "Enable visibility for other devices" because if you're referring to running a command in the miraclectl (which is what it sounds like) it's not clear as to what to run and because of that I stopped after this point.

Also I think I encountered a serious bug (or lack of instruction) because when I got out of the miraclectl and restarted network manager and wpa my router didn't accept the correct password until I rebooted the machine.

albfan · 2019-04-30T23:14:01Z

@codeman101 what about:

launch wifi daemon

$ sudo miracle-wifid &

About Instructions as peer, is true that they are misleading, as that feature is not implemented.

The bug (I guess is that you have miracle-wifid running in background) is because miracle-wifid is running a wpa_supplicant process with Wifi-Direct. That conflicts with NetworkManager. All you have to do is stop the miracle-wifid daemon.

That's why is recommended to run daemon in other terminal, to kill it just with Ctrl+C. anyway you can always kill it with:

sudo killall miracle-wifid

At some point we should use NetworkManager directly, now (since version 1.16) it deals with Wifi-Direct, and running as a service (systemd) istead of manually run the daemon.

codeman101 · 2019-05-01T00:00:46Z

At some point we should use NetworkManager directly, now (since version 1.16) it deals with Wifi-Direct, and running as a service (systemd) istead of manually run the daemon.

That would be great. It would definitely make it more user-friendly so the user doesn't have restart network manger when they want to go back to using the internet.

sudo killall miracle-wifid

You should add this to the readme. If it's running like a true systemd service (or even a general unix background process) killing the terminal it was executed in won't kill it.

$ sudo miracle-wifid &

By the way one of the commands in the readme causes this process to stop. I think it's when I run the command to get into the wifictl.
