Problem getting dual display to work properly
Excerpts from my XF86Config :
VendorName "Videocard vendor"
BoardName "Trident CyberBlade/Ai1"
Option "Display" "Dual"
The problem I have is that if I boot up connected with external projector
and then use Fn+F7 (my laptop is an IBM TP i1300), everything is fine.
If not, no amount of post boot Fn+F7 pressing puts any signal through. I
have lived with this situation for months now but at a recent conference,
this was rather annoying.
How do I fix this problem ?
