Which NVIDIA driver to install for Tensorflow?

I’m running Manjaro-stable, with all the packages up to date. And I have a NVDIA 940MX and a Intel HD Graphics 620 installed.

Here’s what lscpi -v gave me:

GPU details 
01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 940MX] (rev a2)

	Capabilities: [300] Page Request Interface (PRI)
	Kernel driver in use: i915
	Kernel modules: i915

prime-run glxinfo | grep renderer gives me the following output:

 X Error of failed request:  BadValue (integer parameter out of range for operation)
      Major opcode of failed request:  153 (GLX)
      Minor opcode of failed request:  24 (X_GLXCreateNewContext)
      Value in failed request:  0x0
      Serial number of failed request:  39
      Current serial number in output stream:  40

However, DRI_PRIME="1" glxinfo|egrep "OpenGL vendor|OpenGL renderer" gives me:

OpenGL vendor string: nouveau
OpenGL renderer string: NV118

And, glxinfo|egrep "OpenGL vendor|OpenGL renderer" gives me:

OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) HD Graphics 620 (KBL GT2)

I ran DRI_PRIME="1" hardinfo and selected the ‘GPU benchmark’ option. It had run the benchmark using the Intel card.

When I try to run nvidia-settings:

ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system

What can I do to make the NVIDIA card function properly and to take over GPU-intensive processes from the Intel card?

can you report

can you add xdpyinfo?

sudo pacman -S xdpyinfo
inxi -Gxx

I could only find xorg-xdpyinfo. And that packages provides xdpyinfo. The output for inxi -Gxx:

you have installed free drivers ,
open a tty [ Ctrl+Alt +F2 to F7 ) , and quit gnome ( end session gnome )

sudo mhwd -a pci nonfree 0300

then reboot

I did it, and it said Skipping already installed config 'video-hybrid-intel-nvidia-prime' for device: 0000:00:02.0 (0300:8086:5916) Display controller Intel Corporation HD Graphics 620. I then uninstalled video-linux just out of a hunch and restarted.
Now what?

8

now you have lost drivers intel for Xorg
so to correct this do this in TTY

sudo mhwd -a pci free 0300
sudo mhwd -a pci nonfree 0300

check with prime command

Actually, I dunno what happened, but everything is working fine after I did that. Tensorflow is using NVIDIA GPU and there seems to be no errors, at least for the example code I’m running. Thanks for all the help :slight_smile:
