Don't startx as root please. If you have not yet added a user to the system, please read the slackbook on how to do this:

http://www.slackbook.org/

If you plug in your stick and then run thunar, you should be able to see the USB stick device icon on the left pane of thunar. If you click it, it will mount the stick.

If you don't see the icon then it could possibly be a few things:

Check that dbus is running ('ps aux | grep dbus | grep message+' and /etc/rc.d/.rc.messagebus)
Check that gvfsd is running ('ps aux | grep gvfsd')
Check that fuse is running ('lsmod | grep fuse' and /etc/rc.d/rc.fuse).

If you're asking me, the simple answer is "No" but also that I only rarely use startx. Commonly I invoke "kdm" or 'sddm" as root to get a display manager running and land at a GUI Login screen. It is also common that I will enter KDE as root once, after initial install to setup a theme and color scheme entirely unique to root. Then I need never do that again but I also have immediately recognizable visual cues for any application running as root via "kdesu". I never have to wonder or think about it ever again as I instinctively know if any app is as root or user. This has been extremely useful and never once caused any problems in almost 20 years.

I run Slackware without KDE for a while now (since 14.0) and have no issues whatsoever with USB detection and mounting.

@ruy,
could You, kindly please, again:
A. post your current /etc/fstab
B. show the commands You use to manually mount the UBS volumes
C.post a screenshot of the Thunar's settings in regard of USB device mount and detection?

Just in case something is different that the already posted contnet?

@keefaz and @dive:

I´m not running xfce as root, when I run tha command start a root session, I close it and continue with the usual session.

Now I´m upgrade all the system and not load the kernel, so the last issue was minimum (ja ja). Then I format the disk and install windows (I need a particular software that run in windows).
The answer is: should I put the SOLVED in the post?

Thank you all guys. Your answers was very usefull.
