USB-keys do not automount

[erikos]

Revealed in the 13.1.0 OLPC build. They do automount in GNOME that is why I want to check if there is an issue in Sugar.

I tried to do a simple test case on the XO when there is a USB key attached:

from gi.repository import Gio
volume_monitor = Gio.VolumeMonitor.get()
volume_monitor.get_volumes()

This returns no items here.

In sugar-build or in GNOME this works fine. Is there some authentication needed or similar?

On XO-1.75 I see this problem in both Sugar and GNOME.

On XO-1.5 it works.

13.1.0 build 2.

I'll investigate the XO-1.75 problem after the next fedora package push, which should be tomorrow. There's a lot going through so probably doesn't make much sense to investigate until then.

[dsd]

In the mean time, USB disks aren't automounting on XO-1.5 under Sugar, so you can at least continue the debugging there.

Another testing sample: When I manually mount the device on the 1.75 (13.1.0 build 2) the stick is often unmounted when idle suspend kicks in. And then it is available under another /dev/sd*. I did take out idle-suspend now in the CP section and the stick stays mounted know.

The volume_monitor.get_volumes() thing is working on XO-1.75 after the big package push, so that particular test case will be fixed in the next build.

However, same as XO-1.5, no obvious error appears. Happy to keep looking into this myself but it will probably be quicker if someone else can continue the initial diagnosis first. e.g. Is sugar receiving the appropriate signals from gio when external media is plugged in?

[dsd]

I made some progress here on the diagnosis. In sugar, no volume-added signal is raised from the volume monitor when media is connected. But in a trivial test app it works OK. Working on figuring out the difference.
