Hi Francesco.
I know the solution with modeset = 0 but here is the situation :
my default screen resolution is 1366x768 (factory defaults philips )
With modeset=1 then no problem with resolution but no colors.
With modeset=0 then the colors is back but I have 1280x1024 wich is very ungly .
I have tried to force the 1366x768 with cvt and xrandr tools but when I try to add the modeline with xrandr then i get the message :
"xrandr: Failed to get size of gamma for output default"
and I can't go any further.
