Issue with new hid_asus_rog module

[SimoneNascivera]

Hi, I'm trying using your tool with the new asus kernel module (https://gitlab.com/asus-linux/hid-asus-rog) instead of using rog-core, as pointed from the README of the rog-core repo itself. I was able to compile everything with no issues, but when I try running zephyrusblingd it gives me this error:

terminate called after throwing an instance of 'sdbus::Error'
  what():  [org.freedesktop.DBus.Error.FileNotFound] Failed to open bus (No such file or directory)
Aborted

What am I doing wrong? Is the rog-core package mandatory? If so, can I install it along the existing hid-asus-rog kernel module?

Thanks, Simone

Hi, it doesn't use the hid-asus-rog kernel module actually. Everything is sent to asusd which uses libusb to talk with the LEDs, so you should install asus-nb-ctrl (which is basically the new name of rog-core) to make it work. rog-core has actually been deprecated but I forgot to update the readme...

[SimoneNascivera]

Hi, Thank you for the quick response. asus-nb-ctrl is installed and I'm able to use FN shortcut like setting keyboard backlight. It there anything I can do to further debug the issue? I'm using ubuntu 20.04

If there is no error message about dbus anymore, that means zephyrusblingd can call asusd. If there is still nothing on the LEDs you can try running asusctl anime --on in case they are off.

Hi, I had already installed asus-nb-ctrl when I compiled and run the repo and I still get the same error even if the leds are on with the default image (rog one). I'm trying to debug it and the issue is when sdbus cop lib tries to establish a connection. I will try to manually compile last version of asus-nb-ctrl and check if it changes anything.

[SimoneNascivera]

Before compiling asus-nb-ctrl repo the command asusctl anime --on gave me a Command not found error, while after compiling it gives me Error: D-Bus error: The name org.asuslinux.Daemon was not provided by any .service files (org.freedesktop.DBus.Error.ServiceUnknown). After removing /etc/asusd/asusd.conf, I can properly switch the leds on / off with asusctl command but still I can't run zephyrusblingd

It seems the asusd service is not running, what does systemctl status asusd says? Mine says:

● asusd.service - ASUS Notebook Control
     Loaded: loaded (/usr/lib/systemd/system/asusd.service; static)
     Active: active (running) since Fri 2020-10-30 22:46:16 CET; 23h ago

If it's not running, start it with systemctl start asusd as root (and systemctl enable asusd to start it at boot)

[SimoneNascivera]

It seems like it's running

     Loaded: loaded (/lib/systemd/system/asusd.service; static; vendor preset: >

Update: I'm debugging sdbus cpp line by line and the issue appears here:

return std::make_unique<sdbus::internal::Connection>(std::move(interface), remote_system_bus, host);

For context, this is the function where it's called:

    std::unique_ptr<sdbus::IConnection> createSessionBusConnection()
    {
        auto interface = std::make_unique<sdbus::internal::SdBus>();
        assert(interface != nullptr);
        constexpr sdbus::internal::Connection::session_bus_t session_bus;
        return std::make_unique<sdbus::internal::Connection>(std::move(interface), session_bus);
    }

Have you ever encountered an issue with this particular piece of code?

[Meumeu]

It seems like its not able to make a dbus connection, are you using the latest version? There's been a PR 2 days ago to use asusd so if you've cloned it before it's trying to connect to rog-core instead of asusd, that would explain the dbus error.

[SimoneNascivera]

Are you referring to ZephyrusBling or to sdbus cpp?

[Meumeu]

ZephyrusBling

[SimoneNascivera]

I did a clean install of both this repo and of sdbus cpp. After compiling both of them, if I run ./zephyrusblingd without sudo it gives me no errors but when I run in another tab ./zephyrusbling --image ../tux.png --fx scale:0.8,0.8 --fx rotate:0,0:3,19 --fx translate:0,-20,0:3,20,0 it gives me Bling /org/meumeu/blings/3 created but nothing is displayed on the screen

[SimoneNascivera]

It's weird because if I run dbus-send --system --type=method_call --dest=org.asuslinux.Daemon /org/asuslinux/Anime org.asuslinux.Daemon.SetOnOff boolean:true from terminal I'm able to show/hide the leds.

[SimoneNascivera]

Ok I got something. When running dbus-monitor with sudo dbus-monitor --system |grep -A2 asuslinux and running the zephyrusblingd the array data looks empty:

method call time=1604237716.657360 sender=:1.184 -> destination=org.asuslinux.Daemon serial=27 path=/org/asuslinux/Anime; interface=org.asuslinux.Daemon; member=SetAnime
   array [
      array of bytes [

Could you please try the same in order to compare the 2 results? Thank you for your patience

[SimoneNascivera]

Solved. I had to firstly change to a different pattern from the proprietary application in Windows. Then after rebooting,everything works just fine!!!!! Thank you!

[Meumeu]

Good to know, I've never had this issue myself.
