Comment 1 for bug 1908278

UPDATE

...and Debian is the winner! And the first obviously!

Tested on Sparkylinux (Debian testing) with nvidia-graphics-drivers-legacy-340xx (340.108-10) unstable.

System seems working good at the moment.

For those interested driver's metadata is this:

nvidia-graphics-drivers-legacy-340xx (340.108-10) unstable; urgency=medium

  * Backport drm_prime_pages_to_sg_has_drm_device_arg changes
    from 455.45.01 to fix kernel module build for Linux 5.10.
  * Use a version=4 watch file.
