Public bug reported:
After upgrading from 12.10 to 13.04, my Macbook Air does not detect my
TV connected via HDMI and the HDMI-Displayport adapter. HDMI worked fine
on 12.10.
dmesg does not show any signs that anything happened at all when I plug
in the HDMI adapter.
The VGA adapter is still working fine on 13.04.
Upgrading from ubuntu kernel 3.8.0-22 to mainline 3.9.4-030904 did not
help.
