Why can't i use the file search in PCManFM?

When clicking on Tools i am offered a file search (Shift + Ctrl + F), but it is greyed out. I can't look for files! Why?
This is Trisquel mini.
I recently installed the necessary package to be able to use the locate command in the terminal, but that didn't help.
Seems like it is the authentication problem:

I hope Trisquel 7.1 will have this fixed, so that we don't have to be root to look for a file.
I think the alternative Trisquel desktops in general (such as Xfce and LXDE,
but not including KDE or GNOME obviously) just have problems with this sort of
thing all over. Xfce (which I've had extensive experience with, although I've
never used LXDE) under Trisquel cannot mount or unmount drives due to
insufficient privileges- but it at least asks for a password whenever it is
required. It probably doesn't have PolicyKit set up properly.
I'm using Xfce under Debian now, and it took some tweaking in the libpam and
polkit conf files to get it to authenticate properly on startup.
I have successfully switched to XFCE a month ago. It was indeed hard,
and I indeed had to keep an eye on what I was doing (and to tell you the
truth, I almost messed everything up).
I also managed to remove most parts of GNOME. But the main place where I
got some lead as to what to keep in order to have a fully functional
XFCE session, was the article about Xubuntu on Wikipedia, where I knew
that I must keep LightDM and Seahorse; and the online XFCE documentation
and blog posts, where I found that I must also install light-locker in
order to remove other screen locker that comes by default and that I
don't know by name right now. Besides, I experienced some screen lock
and suspend issues.
Also, after everything is installed, be sure to install
"x11-xserver-utils". Then open XFCE's keyboard configuration and assign
a shortcut for "xrandr --auto" to some unique and easy to use key
combination. Because, if for some reason the screen gets locked, and
after entering your user's password, if the screen turns black again
you'll have to use "xrandr --auto" to fix this. It happens in cases
where the system is unable to control the brightness of the display.
This doesn't happen if you go to the applications menu and go to "End
session" and chose "Lock screen", and it also doesn't happen if you use
Ctrl + Alt + Del (don't worry, for XFCE this shortcut locks the screen).
But happens if the system locks the screen automatically.
I remember seeing somewhere that those who want to use XFCE might also
experience a conflict regarding their power management preferences not
being applied or Light Locker Settings not starting. And in the same
place, I found that that was something to do with the way the whole
Light Locker process is invoked. Unfortunately, I can't reproduce the
steps to solve the problem because I can't remember the link/URI of the
bug report.
After installing Light Locker, be sure to edit
"/etc/systemd/logind.conf" in a way that "HandleLidSwitch=suspend"
becomes "HandleLidSwitch=ignore". Otherwise, every time you close your
notebook's lid, it'll suspend, even if plugged to some power jack.
Finally, change XFCE's Power Management preferences in a way that it
doesn't lock the screen or doesn't suspend automatically, both when
discharging and charging. Do the same for Light Locker Settings.

Well, my switch wasn't anywhere near as hard as yours; I just followed the Xfce
installation instructions on the Debian wiki. A few tweaks to the libpam confs
was all it took, and now I have a fully working Xfce with disk management,
locking, shutdown, etc. I haven't tried suspension, but that's because I don't
ever use the suspend function. My computer is either off, or locked.

That was where I had it easier than you- I didn't need to remove any GNOME
cruft to get it to work. I installed X11 and Xfce fresh from a clean text-mode
installation. Interestingly enough, my Xfce works without either light-locker
or LightDM. For my screensaver/locker program, I use Xscreensaver. It works
flawlessly. I don't have a login manager- I just have my computer set to start
in text mode. I then set up a .xinitrc and tweaked some things, and my Xfce
session starts fine with the startx command. I am not experiencing either
authentication issues, or screen locking issues (this with Xfce 4.12 under
Debian Testing).

I didn't have this problem.

I didn't have this problem either. The great Xue smiles upon me from the
heavens. At least I think that's what the Xfce mascot's called... SuperTuxKart
seems to think so. I can't find corroboration elsewhere, so Xue it is.

No problem here either. Didn't have to do this. My screen locks fine when I
close the lid.

Why? Locking works fine for me with Xscreensaver. You must have some really
weird hardware.
Coming back to the original problem:
File search works after installing the package libfm-modules.
