The harware was working well, before my recent upgrades from f38, briefly to f39 and now to f40.  Then I was using the rpmfusion 470xx builds of the nvidia legacy drivers.   Now the dual-boot box has no nvidia or nouveau rpms installed  (rpm -qa) although I suppose bits of config might remain;  inxi still finds nvidia traces:

Nouveau is included with the kernel, it doesn't have its own package.

xorg-x11-drv-nouveau is supplied by fedora, but I was told that the kernel driver was more up to date, so I removed the fformer.

     compositor: kwin_wayland driver: X: loaded: nvidia

This is the xorg nvidia drive, but I assume it's not working if the kernel driver isn't loaded.

llvmpipe means it's using software 3D rendering because it doesn't have a 3d hardware driver.

I don't think I want 3D

There are a lot of duplicates in that list.  If you include "nomodeset", then you'll be using the lowest common factor display options.  Is there a reason you don't want to use the rpmfusion drivers?  It appears that nouveau isn't working for your system, or else something is mixed up. You could check the logs for a previous boot that didn't work.


I have happily used the rpmfusion builds of 470xx until a few weeks ago; but it was said that wayland support was missing, and for some time akmods failed to build anyway. I hoped to be able to use the reverse-engineered FOSS drivers. And a few days ago, after reverting to 470xx, kwin_wayland appeared to be running 4 cpu cores at 90% and the mouse was unusable.

On the linux-only box I have nvidia-gpu-firmware installed. It may not be loading (MythTV says vdpau isn't available) but that system currently does the jobs that I want.

My apologies, by the way, for what looks like a hijack.

John
