Hi ,

 

I just installed ubuntu in dual boot with windows, and now my hdmi isn't working anymore. Is there a link between this problem and the ubuntu installation?

 

I try the hdmi on two monitors and i get black screen on one, and on the other : no input signal.

 

If somebody have a solution for it please Smiley Happy

 

Thanks

 

 

 

Config: Alienware m14x r2 windows 7 and ubuntu 14
