Description Morgan Leijström 2023-05-07 12:16:21 CEST
For the cases I have seen, modesetting works better than nouveau, both regarding speed and suspend-resume (i.e with GPU: GT218M [NVS 3100M] in Bug 31695, as well as with GTX750 [GM107] on my workstation)

Guiseppe also told he experienced modesettign working better on the one nvidia card tried.

However, this is too little data to make a decision, so we think we better gather results and ideas here.

patch to use modesetting instead of nouveau for automatic detecting

I add a patch for using modesetting instead of nouveau for "GeForce 420 to GeForce 630" and as a fallback for "GeForce 630 to GeForce 920" (nvidia470), and "GeForce 635 and later" (nvidia-current).

SPEC file with modesetting fix

As reminder here is the corresponding SPEC file (final version should have the patch moved to git ldetect-lst upstream).

Resulting packages can be tested (manually, sorry) from here: https://copr-be.cloud.fedoraproject.org/results/ghibo/mageia9-bonus/mageia-cauldron-x86_64/05893860-ldetect-lst/

not a qa bug

Comment 4 Morgan Leijström 2023-05-07 23:54:05 CEST
ah yes, I was just thinking qa people test a lot of hardware = experience.


We should write somewhere to tip users to try both nouveau and modesetting.
Until recently I myself thought modesetting was only a parameter...

Release Notes or Errata?

Len reports on qa list that modesetting do not work well at all with NVIDIA GP102 [GeForce GTX 1080 Ti]  :(
