[Bug 571406] Re: monitor does not accept hdmi

[Alexander Bürger]

I tried with the default x server and the 2.6.34 kernel as the only
package from xorg-edgers. That did not improve things.

I noticed that there is only one entry in /sys/class/backlight/ which is
called acpi_video0 and this apparently controls only the backlight of
the built-in laptop monitor.

When booting with the HDMI cable connected, the Xorg.0.log says:

(II) intel(0): EDID for output HDMI1 ...
(II) intel(0): DPMS capabilities: Off

What does this "Off" mean? For the internal screen it says:

(II) intel(0): EDID for output LVDS1 ...
(II) intel(0): No DPMS capabilities specified
