Hi!
I'm running ubuntu hardy on a Toshiba Portege M400
laptop.
If I boot the laptop without the external
monitor, then connect the external monitor
and set up with urandr (or just xrandr), the external monitor
does not display anything. Even if I restart
X using the keyboard (Ctrl Alt <-). The display in the laptop
behaves as if the external monitor
were working.
I have to reboot the laptop with the external monitor
connected to it in order to get the external monitor working.
And in this case, the external monitor works fine, but the
laptop has very low brightness
Any way to solve these problems?
Thanks
