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.

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

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.
Did you log out of X after this point?
Dave.
I wish I could - my computer refuses to logout. It is reboot or shutdown. Am
thinking I may have tinkered something "once too many" and am contemplating
reinstall. But at this moment productivity has to come first so have to wait
Well it won't switch until X exits, worth trying sudo killall Xorg.
