to switch to another virtual console, i would try ctrl+alt+f2 (if the console i wanted were tty2). (also `alt' is the left alt key, not the one on the right.) if that didn't work, i'd try ctrl+alt+fN, where N is some other small positive integer. that's all i got. cheers, wes On Tue, 5 Feb 2013, Alberto Asuero wrote: > We've one server (Ubuntu 12.04) and 20 fujitsu thin clients (same model). > > The system works fine with the most of clients, but some clients (3 of 20) > show a black screen trying to load login window and the system is > completely inaccesible.
