I have otherwise well working Ryzentosh (BigSur, OC 0.7, AMD 5600x, Asus B550) and GT730 with working hardware acceleration.
Now I got Quadro K4200 card (card working well in Windows and Linux). Both GT730 and K4200 are Kepler, so natively supported.
Booting with K4200 results black screen with mouse cursor (moving, so system not halted). It happens after visible progress bar.
I have tried shikigva=40, agdpmod=vit9696 and dart=0 do not give any effect. agdpmod=pikera puts display in sleep instead of this black screen and cursor and NV_disable=1 boots fine, but ofcourse in VGA mode (but it shows that system otherwise works). Also tried DVI instead DP, no help.
In internet I see that people have succsess with K4200. For some people changing working GPU to another one needed booting to Safe Mode once. But I can not boot Safe Mode. -x boot argument results Denied boot logo.
