On Cinnamon 5.0.7 (Linux Mint 20.2), how do I prevent mounted devices, specifically device created in fstab, from showing up on the desktop and Nemo sidebar.

Until recently, this was the default behavior. But after today's update/reboot, pretty much every mounted device is populating the desktop and sidebar.

Majority of these are critical, background devices (e.g. filesystem root, /tmp, /home, ramdisks, etc.) that should never be unmounted. They already have working mount points and need not be shown otherwise, especially with an "eject" button.

sample fstab line of some mounted device that show on desktop and Nemo:

UUID=### / btrfs defaults,subvol=@ 0 1 tmpfs /mnt/ramdisk tmpfs defaults,noatime,nofail,size=500M 0 2

To disable on the Desktop:

Right click the Desktop, click Customize, then click the hyperlink-looking Desktop Settings Button, and slide the Mounted Drives slider off.

To hide specific partitions from appearing in the user interface, you can open the Disks utility (gnome-disks). Then select the devices you want to hide and click the gear icon for that partition: enter image description here

Next, select Edit Mount Options... enter image description here

Next, uncheck User Session Defaults, and uncheck Show in user interface:

Once the system is rebooted, this device no longer showed up in the GUI on my VM

  • You could modify the code to hardcode show_eject_button to false under all conditions github.com/linuxmint/nemo/blob/… Commented Jan 28, 2022 at 19:59
  • I'm not interested in banning the "eject button". I need it for removal device. I just want to restore the default behavior before today's update, where only removal and network devices showed on desktop and sidebar. Commented Jan 28, 2022 at 20:03

    Thanks. This was not the problem. I looked and show in user interface was already unchecked for the partitions. But just did a second rebooted, and all the system mounts disappeared. ¯_(ツ)_/¯ Nevertheless, your info was informative in general regarding mounted devices. Commented Jan 28, 2022 at 20:24

On Linux Mint 21.2 Cinnamon, I add a x-gvfs-hide mount option for the partition I want to hide in Disks application, then the partition is hidden from Nemo and desktop immediately.
