Description Olivier Fourdan 2022-02-02 13:31:12 UTC

Description of problem:

When using an hybrid graphics (Intel + NVIDIA) on a el9 laptop, it's impossible to spawn a client on the discrete GPU from GNOME Shell because there is no option in the menu.

Running "switcherooctl list" from terminal return nothing.

Version-Release number of selected component (if applicable):

switcheroo-control-2.4-4.el9

How reproducible:

Always

Steps to Reproduce:
1. Install the NVIDIA proprietary driver on an hybrid graphics system
2. Make sure the nvidia driver module is loaded
3. From GNOME Shell activities overview, right click on a X11 graphics application
4. Open a terminal
5. type "switcherooctl list"

Actual results:

No option to spawn the client on the distrte GPU in the GNOME Shell menu,
"switcherooctl list" returns nothing

Expected results:

An option to spawn the client on the distrete GPU in the GNOME Shell menu,
"switcherooctl list" lists the GPUs available (or at the very least one)

Additional info:

The issue is the same on Xorg and Wayland.

I can run glxgears on the discrete GPU by setting the envvars "__NV_PRIME_RENDER_OFFLOAD=1" and "__GLX_VENDOR_LIBRARY_NAME=nvidia" prior to run glxgears or glxinfo so the issue is with switcheroo-control most likely.

Comment 1 Olivier Fourdan 2022-02-02 13:46:24 UTC

Note, if I stop the service and run switcheroo-control manually as root then it works:

  $ sudo systemctl stop switcheroo-control.service
  $ sudo /usr/libecxec/switcheroo-control

So possibly something wrong with the DBus or Systemd setup in the package.

Comment 2 Olivier Fourdan 2022-02-02 15:28:52 UTC

Looks like it's just a matter of the service not being enabled:

And once enabled, it works after a reboot.

This is a repeat of:
https://bugzilla.redhat.com/show_bug.cgi?id=2000134#c10
so reassigning.
