I have Ubuntu with Gnome. The window informing about USB auto-detection (action to choose) always occurs when USB drive was plugged. After removing
~/.config directory it stopped working.
How to recover this feature? I don't remember, but it supposed to be nautilus notification. USB device is ok and is visible via
lsusb. Auto-mounting also works.
I don't see an option for this in gconf-editor and nautilus.
