Part of the problem seems to be that Debian is using the default Intel VGA.
Code: Select all
lspci | grep NVIDIA
I've followed the instructions from the Debian Nvidia guide, adding the backport repository (in /etc/apt/sources.list)
Code: Select all
deb http://http.debian.net/debian jessie-backports main contrib non-free
as well as
Code: Select all
sudo apt-get install -t jessie-backports bumblebee-nvidia primus
- I cannot fix the problem through BIOS.
- I made sure noveau was blacklisted. I blacklisted it so hard a new color would need to be perceived to fully comprehend how blacklisted it was.
- I made sure that the bumblebee.conf file used BusID "PCI:01:01:0". I also used "01:01->.<-0" to try to match the lscpi output. Hex formatting of the BusID is not a factor.
- I've used every combination of "Driver=nvidia", "Driver=nvidia-current" combined with KernelDriver
- I made a skeleton .xorg file, even though I'm fairly sure this does not relate to my particular situation at all
- I removed the conf file with "rm /etc/X11/xorg.conf"

I did a new install of Mint to see if I could tease out how it's allowing my GPU to work when Debain isn't. The only drivers it seems to have are the Nvidia-375 drivers, which I had at one point manually installed on my Debian box. I also noticed that mint had "Do not use the device" next to the integrated intel microcode GPU. I'm curious if I were to disable the Intel VGA if Debian would decide to use my Nvidia GPU instead, despite being a 3D controller. But I don't know how to do that and I'm also not sure if it is a good idea. Any advice from the community would be appreciated.
