Inappropriate ioctl for device

[ThomasBucaioni]

By replacing

(trivial-backtrace:print-backtrace e)

with

(trivial-backtrace:print-backtrace e :output *standard-output* :verbose t)

in the file ulubis.lisp, it gives the following output:

> ./ulubis

Any idea what went wrong? My graphics card is an Nvidia, maybe it's related

Hi @ThomasBucaioni,

You are right in that this is likely because your graphics card is nvidia. Nvidia support requires implementing functionality using a different API (EGLStreams used by nvidia, whilst intel and AMD use GBM).

That said there seems to be some movement on nvidia's part to play nicely with everyone else and also implement GBM (see for example https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-GBM-Mesa-Backend-Alt)

Hi Malcolm,

Thank you for the explanation. Maybe there's something I can change in the code to call a different API?
