Description Morgan Leijström 2023-05-07 16:29:04 CEST
Description of problem:

In mga9, drakx11 suggest nvidia-current = nvidia 525, which do not work with my card (very slow, CPU for rendering)

In Mageia 8 it worked nice: the nvidia-current is nvidia470

I have discovered that for this GPU, nvidia470 works great on mga9, like it did on mga8.

( Minor issue after resume: occasionally terrible flickering in i.e Firefox until I move that window (redraw loop bug of some kind) )

> I wonder then if nvidia-current version 525 it is meant to still support "GeForce 745 series and later"or if we should change the selection range (and description)

That's what we need to discover.

The 525.xx driver says it's compatible (supported Series 745, 750 and 750 Ti, e.g.  https://www.nvidia.com/Download/driverResults.aspx/204639/en-us/). But actually, at least on your card, it isn't (card is recognized but works clumsy). Of the two GTX750 device PCI IDs supported, the one with older IDs seems (0x1381) to be badly supported. Remain to understand whether the other card (with ID 0x1407) works or fail too. Mabe it's an upstream bug/regression (apparently reports for upstream are here https://forums.developer.nvidia.com/c/gpu-graphics/linux/148).

Might be revised, and may need note in errata too, when we know more.

Comment 2 Morgan Leijström 2024-01-29 10:12:03 CET
Since a half year or so, nvidia470, nvidia-current, and nvidia-newfeture (in testing) all works with GTX 750.

Quirk: no picture on monitor after resuming from suspend when desktop or server kernels are used. Workaround: 1) power cycle monitor 2) use linus kernel 3) use Xorg modesetting or nouveau free drivers.

Main board chipset Intel P55, it that makes a difference.
