[solved] Unable to mount drives with thunar

CommanderCool · 2012-11-04 15:14:28

Hi,
after a recent update the drives in the thunar side panel ceased to show up. Mounting as root works fine.
I have thunar-volman, polkit... and gvfs installed and up to date. I do not know how the mechanism works, but I thought these might help to locate the problem:

udevadm monitor (on plugging in):

Can anyone give me a hint where the problem could be hidden? Or where to find more information on this "show drives in side panel"-mechanism?

try this:

Identity=*
Action=org.freedesktop.udisks2.filesystem-mount-system-internal
ResultActive=yes

CommanderCool · 2012-11-04 16:07:07

That change has no effect.

opensrcrox · 2012-11-04 16:51:21

I don't use Thunar .... so I'm afraid I can't help with that.
But I wanted to point out that since you're using the latest polkit ( as you mentioned ), the old pkla files won't work.
The new polkit uses "rules" files written in javascript.

So, for example, since I wanted to mount internal drives as normal user, I created /etc/polkit-1/rules.d/10-auth.rules with the following content :

 polkit.addRule(function(action, subject) {
               if (action.id="org.freedesktop.udisks2.filesystem-mount-system" && subject.isInGroup("storage")) {
                       return polkit.Result.YES;
                   }
               }
           );

This takes effect immediately, and I can mount internal drives in e.g. Nautilus without authentication.

Again, the main point is that old pkla files won't work anymore.

CommanderCool · 2012-11-04 16:54:51

That is quite a useful piece of information. I will look into that later when I have time. Thanks so far.

Thanks for your reply. I seem to be logged in correctly as far as I understand:

Concerning opensrcrox's post I was not successful with the mentioned rule. I suppose it is less a problem of mounting permissions (I had that one before; that is why I created the .pkla in the first place) but more a problem of the drives not showing up.

~~In a potentially related matter, I am running another machine with a very similar setup, where all mountable devices appear double in the side panel of thunar.~~

I am actually a little lost here. Maybe it has something to do with me changing to systemd recently?

As far as the double icons in the side panel, this has been common and you might get hints here: https://bbs.archlinux.org/viewtopic.php?id=151856&p=2

CommanderCool · 2012-11-06 18:02:06

Ok, I checked that double icons problem and it was resolved as indicated in the mentioned post. Back to the original problem.

65kid · 2012-11-06 18:06:35

don't use these crappy polkit rules, they are nothing but a workaround.
CommanderCool, please post your slim.conf and ~/.xinitrc.

opensrcrox · 2012-11-06 18:24:36

lol .. the "crappy" rules are sometimes too much of an inconvenience ... but occasionally unavoidable.
CommanderCool .... you listed your original pkla .... but you didn't mention which udisks you have currently installed.
The reason I'm asking is your loginctl status doesn't show gvfs-udisks2-volume-monitor .....
That could be part of the problem.

bgc1954 · 2012-11-06 18:30:20

@ opensrcrox: In his OP he states he has gvfs installed and that pulls in udisks2.

your rule makes it possible for a user in the storage group (which should not be used anymore) to mount internal drives. Why would you want to use udisks to mount internal drives? Why not just use fstab?
These kind of rules are one of the reason why so many people have permission problems since the switch to logind. Instead of actually fixing the problem by setting up the user session properly they used polkit rules to work around the problem.

opensrcrox · 2012-11-06 18:36:18

bgc1954 , indeed ... but I'm curious as to why his gvfs-udisks2-volume-monitor isn't listed in the loginctl status output.
The journal should provide some clues ....

bgc1954 · 2012-11-06 18:39:49

It doesn't in mine either and I'm running thunar as I post this. Maybe CommanderCool check this post for some other ideas: https://bbs.archlinux.org/viewtopic.php … 5#p1188775

Edit: @65kid, I'm glad you agree on /etc/fstab settings.

65kid .... I'm with you on that whole authentication maelstrom.
In my case, I used "wheel" instead of "storage", specifically because I had to quickly come up with a "hack" to make it work using a couple of
examples in the polkit man page.
I substituted "storage" in the rule because the OP mentioned he's in the storage group.
fstab is obviously more convenient.

CommanderCool · 2012-11-06 21:54:16

.xinitrc:

exec openbox-session

As I tried out just now, adding dbus-launch resolves the issue. I once commented that out (as supposed to?).
I will mark this as solved, but is there a better solution? Should I post anything else?
Also, is there anything wrong with using udisks for usb drives?
Thanks to all of you anyways.

it's usually better to remove dbus-launch and use the the .xinitrc from /etc/skel/.xinitrc (part of xorg-xinit). It contains a loop to execute all files in /etc/X11/xinit/xinirc.d/, which also contains a file to launch dbus.

using udisks is fine, my discussion with opensrcrox was about using udisks for something that it is not supposed to be used for (mounting internal drives).
