Connman-gtk shows blank

igorka67

Hallo.
Since a few days i get a blank window on the connman-gtk app.
The connection works as expected.
Am i the only one?

Wat-now

maybe, but you shot try opening it from terminal to see what output it shows

make sure you add your user to the right group, I think network group then reload dbus. what is the output of % id?

igorka67

Wat-now
You mean 66 reload dbus?
I just noticed that if i call ´connman-gtk' as super user it opens as expected.

I suspect this is related to the new dbus release as well. Update to dbus 1.16.0-4 and see if the problem continues

Updated and restarted. The problem persists.

sudo connman-gtk works although the window is not dark like the system theme.
I also tried changing theme but i got no result

Wat-now

igorka67 do you have a dbus group and user? what's the output of %id dbus

wastelander

igorka67 can you confirm that network manager works for you too? Of course you have to enable the 66 service too.

My WiFi is working and if i launch connman as root it works...

nfg

Maybe it won't help, but I just tried to rebuild the upstream. If you update, you can see if that helps. But judging by the errors above, it's likely something else.

igorka67

nfg
The Song Remains The Same... ;-)

wastelander

igorka67 yeah, I just tried to use network manager instead of running connman as sudo, it looks like NM has no issues, it runs as user :)

wastelander

Yeah, same, the app just works if run with sudo. My wild guess is that the dbus new release has some issue with connman, being the latter kinda old software it wouldn't come as a surprise...

nfg

wastelander When you run networkmanager with success as non-root, do you see anything in the root dbus logs?

nfg

Is there anything interesting showing up in the connmand 66 logs?

nfg hmm I uninstalled connman-gtk, deleted the /etc/connman folder and reinstalled it, no joy..also, the /etc/connman folder didn't come back..
