Open Bug 1731480 Opened 3 years ago Updated 4 months ago

libglvnd: If second, unused, Nvidia GPU is present with the Nvidia driver installed, the Intel APU does not have correct vendorID, deviceID, driverVendor, is thus not qualified for HW WR.

Ubuntu 21.04, Nvidia driver 470

  1. Shutdown
  2. Booted into UEFI: Configured Intel APU as primary graphics controller. Saved. Rebooted.
  3. Removed HDMI cable from Nvidia card and plugged it into the mainboard
  4. Booted into KDE, started Nightly, noticed it's still using Nvidia.
  5. Nvidia X Server settings said PRIME offload is active. Selected "Intel (Power Saving Mode)", saved. It wanted a reboot. Rebooted.
  6. Started Nightly and found out it's not qualified for hardware WebRender. GLX/EGL do not matter.

Attached file glxinfo —

Hm, here we're most likely running into:

swrast is reported as fallback software driver. This happens with
unknown sw-drivers (e.g. zink on lavapipe), but also when glxtest
incorrectly detects software rendering. This can be confusing and
is basically always wrong - by now it even got removed from Mesa
and for years only has been used on niche setups.

Make this more clear by using "mesa/sw-all" instead.
No functional change beyond reporting intended here.

Assignee: nobody → robert.mader
Status: NEW → ASSIGNED

Omg, it can be fixed with sudo apt purge *nvidia* and a Firefox restart. No reboot required.

My theory was that I might not be directly using Mesa and the Nvidia driver might be forwarding everything to Mesa. Or it does that only for GLX, but passes EGL to llvmpipe, or something like that.

eglinfo: The only difference between before and after is slightly different ordered "EGL client extensions" right at the top. Everything else is the same.

eglinfo after rebooting once is still the same as right after sudo apt purge *nvidia*.

Could it be that libglvnd was installed? If so, does installing it again bring back the issue?

The presence of libglvnd itself does not seem to be the problem. It doesn't get removed when I purge nvidia.

eglQueryDeviceStringEXT returned EGL_BAD_DISPLAY

That strongly smells like a internal driver error:

        const char *eglQueryDeviceStringEXT(EGLDeviceEXT device,
                                            EGLint name);

   ...

    On failure, NULL is returned.  An EGL_BAD_DEVICE_EXT error is
    generated if <device> is not a valid EGLDeviceEXT.  An
    EGL_BAD_PARAMETER error is generated if <name> is not one of the
    values described above.

The call does not even take a display argument - the previous one, eglQueryDisplayAttribEXT, does, but succeeded. So yeah, most likely not our bug.

llvmpipe:
With Nvidia driver installed:
$ LIBGL_ALWAYS_SOFTWARE=1 clang test.c $(pkg-config --cflags --libs libdrm egl) -o test && ./test

eglQueryDisplayAttribEXT supported

For my example app it does not matter whether LIBGL_ALWAYS_SOFTWARE=1 is set.

left: LIBGL_ALWAYS_SOFTWARE=1 eglinfo
right: eglinfo

  • "EGL client extension" EXT_device_query is always present
  • "X11 platform" and visuals differ

So the relevant question seems to be why does eglQueryDeviceStringEXT return EGL_BAD_DISPLAY with nvidia-driver-470 installed.

$ LIBGL_ALWAYS_SOFTWARE=1 clang test.c $(pkg-config --cflags --libs libdrm egl) -o test && ./test

The LIBGL_ALWAYS_SOFTWARE=1 only works for one command ,not the one after the &&. Can you retest?

Oh, yes.

llvmpipe:
With Nvidia driver installed:
$ LIBGL_ALWAYS_SOFTWARE=1 ./test

eglQueryDisplayAttribEXT supported
eglGetError(): 0x3000 // eglQueryDisplayAttribEXT returned EGL_SUCCESS

bug from comment 0:
We don't know if EGL_EXT_device_drm or EGL_MESA_device_software is supported
because eglQueryDeviceStringEXT(device, EGL_EXTENSIONS) fails with EGL_BAD_DISPLAY
although EGL_VENDOR is Mesa and eglQueryDisplayAttribEXT was ok.

This could be https://gitlab.freedesktop.org/glvnd/libglvnd/-/issues/210.

Btw, this is how it looks when Nvidia is the primary GPU and the HDMI cable is plugged into it:

Looks to me like the nvidia driver does not know the LIBGL_ALWAYS_SOFTWARE variable - which would make sense.

Unassigning for now as to me this looks like a setup/driver bug.

:gw, maybe it's time to close this bug?

Jan, does this still happen? IIRC this should have been fixed in libglvnd.

Flags: needinfo?(gwatson)

Clear a needinfo that is pending on an inactive user.

Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.
