Basic, yes, but not necessarily well known. I'll be that you ran

su - ..

Not sure exactly what you meant there but I did su, not su -

to become yourself so that you effected a login shell, which is what you need to read your groupship. You can either log out and log in again or just ssh to your machine in that window and you'll then have the plugdev group in that shell.

But I just tried su - and I just tried ssh and neither affected the outcome. groups tells me I am a member, adb tells me I am not. I'm not intending to log out, unless somebody convinces me it really is necessary for some obscure linux reason. :)

HTH & HAND

Yes. log out, log in.

It just is so. Log out, log in. :-) - -- Cheers Carlos E. R.

Ah! Success, or at least a step along the road.

There is no need to start a new terminal or to logout.

It's not a linux thing at all. It's adb. It's necessary to run

$ ./adb kill-server $ ./adb -a devices

What is adb? Telcontar:~ # adb --help Android Debug Bridge version 1.0.32

Now I just need to understand the arcane-ness of udev rules :(

Oh, BTW, it seems plugdev is a built-in group on debian. I don't think we have the same on opensuse.

So, Debian, not openSUSE. Or something in Android. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)

On Unix systems, adding a user to a group doesn't change existing processes. That's why id(1) doesn't show the new group right away.

To solve this, you need to log out or you need to start a new login shell, for example by using "ssh localhost". Login shells create a new user instance and attach it to itself and all children.

Actually, just starting a new shell using su user (not su - user) was sufficient, so it doesn't need to be a login shell.

The second approach creates the odd situation that your user will be in the group in some terminal windows but not in others.

Well yes, but that's fine.

Just log in again.

Definitely not! :)

but "su <suer>" starts a "log in shell".

No, it does not. Just do "echo $LOGNAME" after "su <other-user>". -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
