I had that problem too, until I created a file at /etc/X11/xorg.conf.d/nvidia.conf
and put
Section "ServerLayout"
Identifier "layout"
Option "AllowNVIDIAGPUScreens"
EndSection
in it. Then I rebooted and xrandr --listproviders
showed NVIDA-G0
from mate-optimus.
I created that file, but it doesn't seem to have had an affect on my system.

What driver are you using?
from mate-optimus.
NVidia 435.21 from Ubuntu 19.10. The driver appears to be working fine; it's just the optimus applet that would be nice to have.
from mate-optimus.
I see. I found this nice instruction, its for Mint actually, but works well for Ubuntu too. By following these instructions and also creating that file at /etc/X11/xorg.conf.d/nvidia.conf
, I managed to have NVIDIA-G0
show up. Try it out and report back how it went :)

I followed those instructions, I think.
Good:
- I get the
NVIDIA-G0
thing, so the applet detects the driver. - "On demand" mode works: glxinfo shows Intel by default, and shows NVidia with the magic environment variables.
Bad:
- nvidia-settings shows no X display and has can't make application profiles with any actual settings in them.
- Neither nvidia-settings nor mate-optimus-applet can change the mode. It looks like it's changed, but there's no actual difference in behaviour after reboot.
- The applet is therefore not useful.
So, it seems like I can choose between full mode switching via the applet (if I patch it to allow NVIDIA-0
), or on demand switching via environment variables, but not both. Oh well.
I still think the applet needs to recognise both strings.

@a-m-s thanks, good to know. Yes, I agree that applet needs to recognize both strings.
