Tumbleweed wont use Nouveau/Mesa Drivers instead insists on using llvmpipe

[LinuxLightDestroyer]

Hello All!

I have been making a fair attempt at using the nouveau drivers for my GTX 1660 SUPER for the last few hours and for whatever reason Tumbleweed on both Plasma 6 Wayland and Plasma 6 X11 sessions, i havent been able to find any flags in the boot screen that would cause a blacklist nor a blacklist file in modprobe.d. I did a fresh install of Tumbleweed and had the same results. im willing to provide any and all logs necessary upon request

I don’t have any NVidia cards new enough for proprietary driver support, so am forced to use the nouveau kernel driver/module for best performance. I’m not forced to use the nouveau DDX display driver - the difference between it and the default modesetting DIX display driver is nominal on the following card (pinxi is the devel version of inxi):

The above output is from using the modesetting DIX, which produces 651 Glmark2 score. When nouveau DDX is used instead, Glmark2 improves 2.6% to 668. On other cards I’ve seen difference down to zero or nominally in the other direction.

This installation had Plasma 6 and QT6 locked out before it was made available. What it does demonstrate is FOSS drivers for NVidia capability for at least for one card, but my 4 other NVidia cards are all working OK on zypper dups done to TW20240329 or later.

Have you tried both DIX and DDX display drivers? Check out the graphics driver primer (pinned link at top of hardware forum) for more info.
