My experience with Fedora (currently still F29) has been that any
medium I put into a disk drive or USB slot gets mounted, and an icon of
it put onto the desktop -- until now. Suddenly (i.e., over the last
couple weeks), when I put a medium into the drawer and close that,
nothing visible happens. When I go flailing through sundry menus looking
for an app to mount that medium, it usually just claims blank medium or
none at all; but, once or twice, it tells me I have to be root.
My guess is that what I have loused up this time must be
somewhere in the configuration files. I've tried as many of those as I
could find, but especially Caja, since I run Mate. Clue, please!
You can use 'sudo journalctl -f' to follow along what events happen
when you insert the stick. I expect first few lines are kernel
related. It must see the USB stick. If that doesn't happen, there's no
chance it can be mounted. In my case, roughly the first 20 lines are
all kernel related, with some mtp-probe in between those messages.
Next systemd instantiates all of the aliases for the device, but you
only see this if systemd is in debug mode. Same for systemd launching
udisksd.
May 06 16:11:12 fmac.local systemd-logind[977]: Inhibitor Disk Manager
(Mounting Filesystem) pid=900 uid=0 mode=block started.
The next non-debug item I see is udisksd actually mounting the volume:
May 06 16:11:12 fmac.local udisksd[900]: Mounted /dev/sdb1 at
/run/media/chris/LEXAR on behalf of uid 1000
I'm not certain, but suspect Mate would use the same mechanism in
systemd and udisksd
For comparison this is the full debug follow output for Fedora 30
