[SOLVED] KDE Plasma 5 - problem with mount - polkit?

Oh, that problem! Sorry, I'm already used to it so didn't think about that.

As far as I know, this is not some intentional change by upstream, it should behave the same but wasn't yet figured out why not...

FWIW, I don't see any checkboxes or anything like you guys are talking about. (But I solved my problem with polkit config; see above.)

I guess the different desktop themes are complicating this discussion :-)

Will fiddle with my settings later after work and see if I can reproduce your views.

Cheers, Ian

I don't think the theme matters, but in case it does, I'm using:

* Oxygen for the Widget Style
* Seven Black for the Window Decorations
* Obsidian Coast (Sunset) for the Application Colour Scheme

Okay, I set my desktop theme to Oxygen, and now when I hover over the tick mark, there is a popup telling me to click it to mount the flash drive.

Clicking it causes Dolphin to open.

I went back to Smoother 5, and the behaviour is different.. this time I did notice popup, but clicking the tick just gives the summary graph of the drive... it does not fire Dolphin.

I switched to Breeze desktop theme and same behaviour as Smoother 5, which is odd as Breeze is default for Plasma 5.

FWIW I'm on stable branch of Plasma.

I also recompiled kde-apps/kdebase-kioslaves last night which pushed the version from 15.08.1 to 15.08.3 (IIRC), I don't know if that had any effect.

Tried Air, same result. Went back to Oxygen, and now it also works like the others, and does not fire Dolphin until I click on the graph.

Conclusion: this subsystem is still buggy. :-)

I have to agree with iandoug

Hi,

I just tested this on new amd64 stable system and Plasma 5.5.5 (previously ~amd64 & Plasma 5.6.2), the same problem - no access to any memory sticks or cards for ordinary user - so doesn't matter you use amd 64 or ~amd64.

Is there any solution for Gentoo users without manually changing polkit files? I tested KDE Mint and Kubuntu and those systems works just fine.

@Xywa: Please specify what issue you have exactly. How do you mount your media, do you click on the green icon in the device notifier and it does not work? Have you finally fixed your consolekit session (I remember you had wrong session information in ck-list-sessions)?

It's a bug, not intentional UI design.

I have added the two files, Pistos told here, to the system.
That removes the 'An unknown error occured - NOT autorized...' - warning.
Maybe after a re- login btw. X restart it will work to manage the devices over the knotifier (?) I'll see.
But what I want to add here in this thread is:
On the (most stable) Kernel 3.16.1 I had before, it all worked nicely!
The problem, that I can't mount over the Human User Interface, (afaik; KDE) firstly came, when I updated to kernel 4.4.6!
Also I do still use the unmaintained KDE4 and not the Plasma5. There, I*ve heared of, strange behavior. So long.

Maybe that could help. :oops:

Thank you guys for the solution, it is definitely a bug that the device mounter is unable to mount it and you have to click on that little icon to call a dolphin.
The possible commit which introduced the bug (and this message) is below:

Not likely. The issue was present well before 5.6 already.

Had the same problem. Missed rule for dbus. Fixed by creating required rule:

$ cat /etc/polkit-1/rules.d/51-kde5-device-mount.rules

Thanks @feniksa, your solution worked for me.

In my case, the problem was that I was trying to mount an exFAT filesystem, but didn't have sys-fs/fuse-exfat installed (I've only had this box dual-bootable (Gentoo and Win10) for maybe a month and have installed packages as I've needed them). The error message returned by KDE obscured the nature of the problem by making it look like some sort of permissions error; it should've said something about not having support for the filesystem on the device. Once fuse-exfat was installed, it worked like a champ.
