I have three xubuntu 11.10 systems running here, one is a 32-bit laptop and two are 64-bit desktop machines.
USB drives plugged into the laptop and one of the dekstop machines get automounted correctly but on the other desktop machine although the USB drive is recognised (appears in dmesg as it should) it doesn't get automounted.
So how can I diagnose what's wrong or missing on the desktop machine where the automounting doesn't work? I think it's *possible* that I have removed something necessary and/or misconfigured something as this machine is quite heavily customised.
As I have a working machine and a non-working one I may be able to compare things between the two machines to see what is wrong but I need to know the sort of places I should be looking.
What processes and packages are involved in automounting a USB drive? As I said it appears to be recognised correctly by the kernel, messages in dmesg and syslog are the same on both the system where it's not automounted and the system where it is.
After the kernel has recognised the USB device as a mass storage device what then mounts it automatically and (if configured to do so, which it is) pops up thunar?
Any/all help would be most welcome as this problem is getting really annoying!
