To complete my previous question ,
( http://lists.freedesktop.org/archives/xorg/2008-October/039770.html )
I'd like to know what should I do to force DVI to be activated on boot time.
I write this at the end of the ch7xxx_init, and now it works randomly.
pm = ~CH7xxx_PM_FPD;
pm |= CH7xxx_PM_DVIL | CH7xxx_PM_DVIP;
ch7xxx_write(dev_priv, CH7xxx_PM, pm);
I noted that the register 20h bit 5 DVIT is the one that is activated when
the screen is plugged in but this register is only readable.
I certainly miss something but what?
Just to remind, I'd like to activate my DVI output over DVO at boot time; it
works well when the screen is plugged in at boot time but if not, it doesn't
work every time.
