xrandr doesn show any HDMI
I have a laptop (Asus N55SF) with NVIDIA GT555M GPU, with Elementary OS installed (based on Ubuntu). I have Bumblebee installed, with NVIDIA drivers, which works. (optirun glxspheres has higher fps than just glxspheres)
When I connect a display to the VGA adapter, everything works fine. However, when I try to connect a HDMI device, nothing happens. The HDMI port works on Windows 7 and 8, so hardware failure can't be it.
The weird thing is, when I run xrandr, I get the following output:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 LVDS1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm 1920x1080 60.0*+ 59.9
1680x1050 60.0 59.9
1360x768 59.8 60.0
800x600 60.3 56.2
VGA1 disconnected (normal left inverted right x axis y axis)
There is no HDMI device listed using xrandr! I searched the web, tried some other drivers, but I really have no clue what to do next.
Someone who might know what the problem is here?
