So I currently have a dual-ati video card setup on my laptop. A low-power one and a high power one.
In windows 7 the drivers switch video cards when on external vs internal power. Also one of the video cards contains an HDMI output which I would like to use as it lets me plug in my monitor.
So is there an easy way to configure this?
- Radeon HD 4200 - Low power
- Radeon HD 5600 - High power (contains the HDMI output)
Potential acceptable solutions:
- Deactivate low power card and use high power only. Worse battery life but whatever. However I don't want this done in BIOS since I want the good behavior in windows when dual booting.
- Get low power card working without high power card BUT HDMI output needs to work so I can plug monitor in.
aticonfig --adapter=all --initial finds both adapters after restart. The problem is X cannot start. It goes to black screen and must be restarted.
aticonfig --list-adapters only shows one adapter in a working config. The undesirable
configuring the high power adapter leads to same x not loading as --adapter=all
