[SOLVED] USB media not shown on desktop

the_yellow_dwarf · 2024-12-05 11:06:05

Hello everyone big_smile !

I am not very sure the problem is dedicated to XFCE.

From a freshly installed Debian 12 system, with an XFCE desktop environment, USB external media (keys, hard drives) are not shown on the Desktop even though the latter is configured to display them, nor they are displayed in the thunar file manager.

However, these media can be mounted without error, are operational and well detected by the Linux system (as evidenced by the commands below).

Too, from a Windows 10 system (dual-boot) the media are directly displayed.

Oddly enough, a smartphone is displayed on the desktop as a USB device (see command returns below).

In virtualization (QEmu/KVM), on the same Debian 12 system, these same media are nevertheless displayed on the desktop.

Finally, the following packages are installed: udiskie udisks2 policykit-1-gnome dbus thunar-volman xfce4-goodies gvfs* fuse3 ntfs-3g

Where are the drives mounted on the filesystem? Can you run the "mount" command on both computers so we can compare?

the_yellow_dwarf · 2024-12-06 19:18:39

Hi ToZ smile

I do not understand what you want to know.

When I plug a random USB key or an external hard drive they will not be shown on the deskop area and too they are not auto-mounted, then they are not mouted.

Here is what I obtain on a default install on the same machine (faulty system backuped before) :

I will publish the same operations once the faulty system is restored (for now I have a buggy problem to add again the Debian partition in UEFI BIOS ; the machine is a dual boot with Windows).

---

I advanced on the subject. It seems that after a fresh install of Debian the USB devices previously indicated all are directly operational. So I tried to discover the difference between the faulty install and a fresh install in comparing the list of packets and their versions. But there are so many that I do not know where to look at first.

Too for me it is not a problem of permissions as with a root session the problem is the same

Is thunar-volman installed and running?

Installed : yes (see the 1st post), running I am not sure ... Is it a service/daemon ? Else how to verify that ?

eriefisher · 2024-12-06 21:52:54

Open Thunar and under Edit>>Preferences>>Advanced Tab. On the bottom there should be a check box for "Enable Volume Management". Check it. Once enabled usb devices should appear on the left pane of Thunar and on the desktop if permitted. You can also click on "configure" to specify what you want done with the usb devices.

Hi eriefisher and thank you smile The problem is outside thunar as the devices are not shown on the desktop (while it should since it is configured by default to display them). However thunar is configured in this way.

So the usb drives show up in Thunar, just not on the desktop? Do you have other icons on the desktop?

I think my situation is not enough clear ...

When I finished to install a machine (which took me a lot of time), I observed a plugged USB key (perfectly functional) was not shown automatically on the desktop while it was mountable without errors (see the 1st post).

I backed up the system to have the possibility to restore it later in the same state.

Then I dug to resolve the problem and I started again a fresh Debian install on the same machine with the XFCE Desktop Environment and the SSH client/server to allow the remote access, nothing more.

At the first login the USB key was directly shown on the desktop without any else configuration of mine. As I spent a lot of time to build the machine to fit the user needs I wanted to know what to do to correct the problem without not having to redo all. Is it more understandable ?

mint4all · 2024-12-07 21:21:30

Greetings --

If it helps any, Mint 21.3 with XFCE 4.18 shows the appropriate icons on the desktop when a USB-drive is inserted and mounted. The desktop settings used to contol the display of these icons properly toggle the display on/off, and do not require a logout/login or reboot to work properly.

Cheers, m4a

Well, finally I found and solved it myself. And it is not with my technical skills that I found what was stuck but with the spongy body that I have between my ears tongue

The problem came from a too restrictive udev rule, which was supposed to hide the Windows partitions of my dual-boot on the desktop but which hid them all. I had completely forgotten this modification and I must have also forgotten to test with external media.

I will search a method to detect this kind of problem in future and I will make a return here.

Then ... resolved smile

---

The method to detect :

A udev rule which hide all nvme* partitions (my main boot device) and shown with journalctl

sudo cat << EOF > /etc/udev/rules.d/10-hide_parts.rules
  # Cacher partitions sur le bureau et gestionnaire de fichiers
  KERNEL=="nvme*", ENV{UDISKS_IGNORE}="1", \
  RUN+="/usr/bin/logger -s udev : hide nvme partitions"
EOF

Retrieve the custom rule from journalctl :

sudo journalctl -b | grep nvme
déc. 19 17:54:57 host root[310]: udev : cacher partitions nvme

That is all folks big_smile
