X11R6.9 uses similar console switching keys as the SCO R4 and R5
servers. That is, Ctrl-PrntScr takes you to the next console along
from the one X is running on. If this is the last console it will take
you to console 1. Ctrl-Alt-FXX, where XX is a function
key between F1 and F12 will switch you to the console
number assigned to that function key. F1 corresponds to
tty01 (or console 1), F2 corresponds to tty02
(or console 2) etc.
Unlike the SCO X server, the "kill me now" key is Alt+Ctrl+Backspace.
This does not ask for confirmation, it simply kills the X server as
immediately as possible. Use with extreme caution. This may cause
applications to terminate in an unpredictable way. You can set the
DontZap option in the ServerFlags section of your
XF86Config file to disable this.
