That's been their position foe over almost 2 years now...
Wait a minute... So normal is which both GPU's on? ...And these swithes turn the nVidia driver off or on... nothing with the Intel GPU? Then the Bios Hack turns off tthe Intel GPU forever... (which would affect Windows drivers if dual boot) and does not add a function to switch GPU's on and off, or one as priority over another...

what do you think?
That is in this thread a "lot"... In the xorg.conf file under Section Device,,, it tells the driver to use the BusID listed there to find the Video card or GPU.
You can get the BusID from
Code:
lspci -nn | grep VGA
on this box returns
Code:
mafoelffen@maf-ubuntu-01:~$ lspci -nn | grep VGA
03:00.0 VGA compatible controller [0300]: nVidia Corporation G92 [GeForce 9800 GTX] [10de:0612] (rev a2)
Which the part highlighted above in red, goes into the xorg.conf as
Code:
Section "Device"
:
BusID "PCI:3:0:0"
:
EndSection
I don't know/,ever tried, because I don't have my own of that to test... To do that you need gen an xorg.conf file using
Then edit to add your PCI BusID of the nVidia CPU...
Code:
sudo gksudo gedit /etc/X11/xorg.conf
After the changes. save. Then
Code:
sudo nvidia-xconfig
sudo cp /etc/X11/xorg.conf ~/xorg.conf.nv
That will copy a backup to your Home directory... Please post it here as I'm curious.
Restart GDM to test
Code:
sudo service gdm restart
I don't think it will, so If it hangs Xorg... <cntrl><alt><F1>
[code]
sudo service gdm stop
sudo rm /etc/X11/xorg.conf
sudo service gdm start
Code:
Then you should be back to normal
The reason I think it will hang it his. I do NVidia SLI on 2 of my boxes. One boxes is a 2-card SLI and the other has 3. For me to install on a fresh install, I have to pull all the card except one > install the driver > Install the cards back in and SLI bridge them > Restart. Then the "driver" takes care of the multiple instances. Otherwise those multiple instances cause a lockup.
I've wondered about multiple GPU's where the GPU's where different. You know, I thought it might be logically possible, but I was "told... I don't know for sure. Maybe I should email Alan C He used to answer my "advanced" kind of questions related to xorg. lf xorg-server (v1.10 , v1.11 or future) can handle that...
