Anyone manage to switch ON discreet graphics?

 

As can be seen in subject, my query if anyone has found a working method to switch ON discreet graphics and OFF integrated.

My hardware is a HP Pavilion dm4-1050 with the least usable BIOS I have ever seen. One upgrade actually broke the possibility in both Win7 (have kept a partition) and Linux to switch wireless on/off. Only good thing is that it allows downgrading bios so I got that functionality back.

OS: Kubuntu 10.10 32-bit with all upgrades
Model details:
HP Pavilion dm4 Notebook PC

using vga-switcheroo I can switch OFF discreet graphics and run on integrated only or switch ON both and get a hot, batterychewing computer. Vga-switcheroo can not switch over to discreet only, I get this from dmesg:

and that is it. I tried to compile the module and run the test.off script. Managed to compile but the kernel I was in went nonresponsive completely on running the script. Lucky I have several generations so managed to sort that problem.

Anyone has any sites to point to or ideas feel free. Switching off is OK but I like to use the hardware I have bought. Only thing is I was unaware I bought a "switcher", only the ATI was announced in the specs.

Kind regards
Sinclair
