Hi,
Are you still using Ubuntu? (I noticed Dapper Drake in your email.)
Ubuntu allows for having the libraries installed side-by-side and then
use the alternatives
system to set the OpenGL at your choice. Bumblebee sets the default
driver to Mesa
(necessary for the Intel GPU) and sets the ModulePath to the one
containing the nvidia
drivers.
For the Bumblebee project, see
https://github.com/Bumblebee-Project/Bumblebee.

Hi guys,
I have a new Thinkpad W520 with Nvidia Quadro 2000M and an Intel
HD 3000.
Maybe you know that it has a hardware mux, so I could use both of
them, but I have to switch in BIOS and install/uninstall the
nvidia driver.
In optimus mode, I can only use the Intel card, including 3D
acceleration for it (if nvidia driver isn't installd), but the
nvidia card is still active. Thanks to acpi_call, i think i
managed to disable the nvidia card:
I have to unload nouveau ( rmmod nouveau ), then to load acpi_call
( modprobe acpi_call), and then I can run test_off.sh, which works
with the method \_SB.PCI0.PEG.VID._DSM. After that, the card still
shows up in lspci, but it doesn't show up in powertop anymore.
I adapted Erik Andresen's script for his T420, and now it works
for me.
But there are still 2 problems left:
1. The rc6 sleep state of the intel gpu doesn't work (not really a
problem for this mailing list, i know)
2. I can't use 3D acceleration parallel with both GPUs. Do you
know a way how to install the intel and the nvidia driver parallel
without letting nvidia's one overwrite the intel libraries for 3D
(I think that's why the intel one doesn't accelerate when nvidia
driver is installed)?
If i could install them parallel, my next step would be to try out
ironhide or bumblebee.
Thanks in advance, and sorry for my english,
Matthias
