What I try to achieve

Using both my Intel chipset and my GeForce 940M.

My configuration

Laptop model : Asus Zenbook UX303UB

$ lspci | grep -E "VGA|3D"
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07)
01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 940M] (rev a2)

$ lsmod | grep nouveau

$ uname -a
Linux user 4.6.7-300.fc24.x86_64 #1 SMP Wed Aug 17 18:48:43 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I followed the following guides

What I would like

  1. Simple usage of desktop application, using nVidia GPU if needed (i.e. automatic offloading)

  2. Shutdown nVidia card to enhance battery life

  3. Bumblebee seems to be a good option as I have to manually launch applications with optirun

I will provide any needed information :-D Just ask in the comments. I have a limited knowledge about Linux (only basics stuff) and nearly null knowledge about graphical stuff (X, rendering process, etc...).

  • This is no help to you now, but I know the graphics team is working on making this work better for Fedora 25 and beyond. See fedoraproject.org/wiki/Workstation/… – mattdm Sep 1 '16 at 22:51
  • thank you very much for this information anyway :D could give help if needed ? (like, info/log/anything else) – mithrop Sep 2 '16 at 13:10
  • Let me check... – mattdm Sep 2 '16 at 13:21

I know Arch is the pinnacle of Linux distro documentation, but in this case there is also an Excellent guide to Bumblebee on Fedora.

Unfortunately, I'm afraid this will get you to the same place: "it works :D but I have to use optirun everytime :-(", which, by your sad-face, is not what you want.

The good news is that better Optimus support is in the works for Fedora 25 and beyond (see Fedora Workstation — Tasklist), although I know that doesn't immediately help you.
