I'm not that new to Linux but just used it the last years for server and/or testing most often in VMs. Now I've just got a new ThinkPad and I want to use Debian as a native install.
Lenovo ThinkPad t460p with a
NVidia GeForce 940MX
(German Shop Site for additional details).
But now I'm wondering which additional steps I have to do since my notebook has two GPU (Intel + Nvidia). I had installed the Nvidia-driver package via the Debian backport source (not sure if this was correct) like described in the Debian manual.
When doing a
lsmod | grep nvidia the Nvidia entry will be listed (as far I understand that means, that the Nvidia driver is loaded and nouveau should not). I'm trusting the original Nvidia driver in general more than the nouveau because I want to be sure that my card is optimal used; also I've heard about nouveau today the first time). Anyway their are some Points I'm wondering about:
#lspci | grep VGA returns only a Intel entry:
00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06)
No NVIDIA GPU detected.
#lspci | grep NVIDIA returns
02:00.0 3D controller: NVIDIA Corporation Device 134d (rev a2)
As in many tutorials described, I should install the Nvidia-xconfig package to be able to run
nvidia-config for creating a xorg-config-file.
Maybe I don't have to do anything and that is all right? It's correct that my system should only use the intel-adapter per default. Just when running some intensive OpenGL-Applications, the Nvidia should be used (at least that is the behaviour I'm used to from the windows-world).
One more idea is, that I have to use that bumblebee-driver I've just found...?
Hope you can help me with this noobish-problems so I can switch away from windows. :)
