Ok thanks for the information.  I had a closer look, and this test box actually uses the regular xf86-video-nvidia driver, so hopefully that will be supported sooner, since as you mentioned, the driver changes were fairly trivial.  I guess now I wait for Nvidia...

The "modern" xf86-video-nvidia driver (albeit 435.21 - short-lived branch - and not 430.50 - long lived branch - that LibreELEC is using) is allegedly working with 5.4-rc2 although the xf86-video-nvidia driver has not been tested with LibreELEC (so few members on the LE Team use Nvidia GPUs) so if it failed for you that's a bit disappointing. Can you try #1008x and - if it fails to load the driver/fails with xorg errors - log in with ssh and try running pastekodi the paste the url?

EDIT:

Sorry, as it turns out, this test box has an ION graphics card, and uses the regular xf86-video-nvidia driver. Your release notes mentioned it was untested, and likely non-working - I can confirm you are correct

Hmmm... ION is definitely using xf86-video-nvidia-legacy and I don't think it will use the "modern" xf86-video-nvidia as the latter doesn't support the ION/ION2 GPUs. You may have some luck with #1008x and your ION GPU, as this build now includes the xf86-video-nvidia-legacy driver but probably only as far as the Kodi GUI...
