Some versions of SVR4 (Esix and Microport) have mechanisms for enabling
two-key sequences for VT switching (Alt-Fn).
The standard SVR4 mechanism
is Alt-SysReq-Fn, which all versions we know use.
Running under X, the
Alt-Fn sequences are stolen by the driver before the
server can see them,
so you can't use them for X applications. So you want to switch back to
the standard 3-key sequences while you are running X. Here's how to do
it:
Microport makes this very simple. The 2-key mode is called
"Microport Mode", and the 3-key mode is called "Compatible Mode".
You enter Microport Mode by pressing Alt-SysReq-m. You enter
Compatible Mode by pressing Alt-SysReq-c. So all you
need to do
is press Alt-SysReq-c after to allow X clients
access to the
Alt-Fn sequences.
Esix has no keyboard-driven way to switch modes. There are two levels at which this can be handled:
/etc/conf/pack.d/kd/space.c. When set to 1 (the default),
2-key
mode is enabled. When set to 0 it is disabled.
xc/programs/Xserver/hw/xfree86/etc/
in the source tree, and in
/usr/X11R6/lib/X11/etc/ in the binary
kit). You can compile and install this program. Then to make use
of it, add the line `VTInit "2key off"'
to the Keyboard section of
your XF86Config file to cause the program to be run
automatically
when the server starts up. Doing this means that 2-key switching
will be turned off while in the server's VT, but will still be on
for the other VTs.
