Can You ilustrate how to video units assigned with /dev/tty's

[Aivils S. <Aiv...@un...>]

Hi
Can You ilustrate how to video units assigned with /dev/tty's?
How many tty's per unit?
Where determined concrete /dev/fbX<->/dev/ttyX binding?
con2fb couldn't compile with ruby fb.h.

I try 3dfxfb.c v1.17 and get no prompt or blank screen.
VGA console and Voodoo3 framebuffer configured.
Two keyboards is attatched and mapped with two different vt pointer
(checked in keyboard.c, kbd_connect()).
Must take_over_console() in framebuffer init routines called?
Must be additional getty in inittab for second framebuffer added?



I patch 3dfxfb.c . This one allowed compilation.
Don't know corpse code logic or not.
