HEllo Back,
Sorry for the delay.
I have installed a vanilla Raring (Build of 23 February) for testing purposes
and tested right away the HDMI support. SO this is what I obtained so far:
- HDMI is indeed recognized: When I plug the HDMI Cable in the laptop's HDMI
port and the monitor, the monitor is recognized and I can see that in the
DISPLAY (System settings) applet, as well as using XRANDR -q command.
- HDMI Audio is not supported (the Nvidia Audio through HDMI is not routed).
- Only the MIRROR option is functional (Mirrored displays): If I try to disable
the laptop display and let the external display enabled, lightdm restarts
immediately or I get an error of type:
-- gnome-settings-daemon : CRASH triggering apport-gtk.
-- DBUS error popup saying that the new configuration cannot be written (Right
after clicking on Apply button). I did not test directly with xrandr commands
but I suppose the same results would be produced.
