gnome-disk-utility User Session Defaults issue
Hi.
I am using Debian Unstable (64-bit), Cinnamon desktop environment.

I have gnome-disk-utility (a.k.a. the "Disks" program) installed.
In "Disks", for each partition (/, swap, or home), on the primary
(only) ssd, if the partition is highlighted and the "gears" icon is
clicked, a menu pops up with one of the choices being "Edit Mount
Options". When "Edit Mount Options is clicked, a window titled "Mount
Options" appears.
Near the top of the mount options window is a slide switch labeled
"User Session Defaults". If you rest the mouse pointer on the slide
switch, a popup text box says "Switch off User Session Defaults to
manage mount point and mount options for the device. The options
correspond to an entry in the /etc/fstab file."
Until recently, for all partitions on the main ssd, the slide switch
was "on" by default, with the slide background colored blue, and all
of the text in the fields for the options in the window were "greyed
out".
But now, for all partitions on the main ssd, the slide switch is "off"
by default, the slide background is colored grey, and the text in the
options fields is black, not grey, and is editable.
Now if I slide the switches to "on", and click "OK" to save the
changes (requires authentication by user sudo password), the computer
will not reboot after shutdown. Using a rescue disk to inspect
/etc/fstab on the main ssd reveals that changing the User Session
Defaults switches for each partition has caused the corresponding
entries to be deleted from /etc/fstab.
Replacing /etc/fstab with a backed up good copy allows the computer to
boot as normal.
BUT, restoring the backed up /etc/fstab causes the "Disks" slider
switches to change back to "off" by themselves! No matter what I try,
I can not get /etc/fstab and the User Session Defaults switches to not
change each other. Very strange . . .
Note 1: all of this behavior affects only the partitions on the main
ssd. It does not affect the "Disks" Edit Mount Options windows for
the dvd drive or any external usb drives that are plugged in. For any
drive other than the main ssd, the User Session Defaults switches
default to "on", as expected.
Note 2: in the Edit Mount Options window for each partition on the
main ssd, the 'Identify As" field lists a UUID entry (ie,
UUID="93082123-a386-41ce-8067-fafbf5892691 for the swap partition).
But
for any partition or drive other than on the main ssd, the 'Identify
As" field lists either a device name entry (ie, /dev/sr0 for the dvd
drive), or a /dev/disk/by-id entry (ie,
usb-HP_v125w_8EIYHFB131ZYW5I4-0:0-part1, when an external usb device
is plugged in.)
Therefore I wonder if this has something to do with entries in
/dev/disks/*, but that is just speculation. And since I know nothing
about /dev/disks/* and how it works, I am somewhat reluctant to do
surgery there without knowing what I am doing.
-----------------------------------------------------------------
Here are the /dev/disk/* entries, with no external devices attached:
/dev/disk/by-id:

So, I would just like for the old behavior to return:
1) The computer boots, without issue.
3) User Session Defaults will show in the "Disks" program as turned
"on" (and stay that way)!
3) A good /etc/fstab that doesn't change by itself when User Session
Defaults is turned on or off!
Thanks in advance for any help on this!
