Another post about ArchLinux, just to keep the info somewhere. Today I was playing with the LXDE destktop. When using the filemanager (PCMan filemanager) I tried to automount a plugged in USB stick. No luck at first shot. Going through the ArchLinux wiki I found how to fix it. The point is the combination of the last HAL version and PolicyKit. I was starting my session with exec startlxde so the desktop was not aware of any PolicyKit stuff. The solution, as explained in the wiki, is to launch the session as exec ck-launch-sessoin startlxde. Afther that, and having DBus policies configured, automount was successfully working. You can check it in detail in the corresponding wiki page.
