Hello. I have a Gentoo linux installed on a MacBook Pro.
I use Refit as first boot loader, then lilo as linux boot loader.
When i select the linux boot from refit the external monitor turns to standby.
Linux boot well and only when it reaches the Xorg loading the external monitor
turns on again.
If i switch to a virtual terminal with Ctrl+Alt+F1 the external monitor turns
off, then switching to the X screen with Ctrl+Alt+F7 it turns on again.
I would like to be able to use the console from the external monitor, but i
cannot force it to wake up.
I've tried vbetool to send a dpms signal, but it just change the main monitor
state.
