Hi,

Daedalus installed on a HP Pavilion a6345f here. With the monitor
connected to on-board video, the system works with no obvious problem.

I use two screens and fit a Radeon X600Pro 256MB V/D/VO adapter to the
PCIE X16 socket.

In the BIOS, PCIE X16 was set as primary. No problem evident from the
BIOS.

The GRUB display appears and daedalus can be chosen.

This line appears on the screen. 
[    0.000028] x86/cpu: VMX (outside TXT) disabled by BIOS.

After about 2 minutes the screen turns black. That remains except for
an occasional brief flash of message. May be the monitor notice of
absent video input; too brief to be certain.

The result is the same when VMX is disabled and when enabled.

Anyone using this or similar machine? With two screens? Anyone using
this Radeon adapter?

Additional ideas?

Thanks,                   ... P.
