I have two identical Acer tablet Netbooks with Ubuntu 12.04 LTS installed, and being new to Ubuntu, I have tried hard to keep their settings in sync, so I know better through changes if the system breaks or if I break it.
I have noticed that when I plug in a USB memory stick, one system mounts the device and opens a folder on the desktop right away, while the other seems to ignore the hardware and nothing happens (despite the light on the device initially blinking).
I have gone into System Settings -> Details -> Removable Media (which Ubuntu Help refers to) looking for a setting to specify how Ubuntu should treat this media, but I have noticed both tablets seem to be set the same way (although none of the choices seem to explicitly refer to flash drives).
Is there another or more basic way to control how Ubuntu treats media and verify those settings than the System Settings panel?
