Don't know what's up with this, but there's nothing we can do about issues with nvidia-drivers-390.xx unless it's a packaging issue. It's closed source and NVIDIA no longer supports this branch (since December 2022), and so will not fix anything even if reported. Eventually we'll need to drop 390 from gentoo's repos when it's too broken like we did with 340 and older. If your cards need 390, only thing I can suggest is either switch to nouveau or get new hardware. Albeit that GTX770 should be Kepler and work with nvidia-drivers-470.xx (with still years of support ahead) while the GT730 is afaik a late Fermi model and won't.
Thank you for the kind answer.
The source of the problem was nvdia-glx not loaded Somehow X loaded mesa glx too soon and refused to load nvidia's glx Since there is no more eselect-opengl and this should be handled by libglvnd, but it wasn't, I just overwrote mesa's libglx.so with nvidia's, and everything works now.
Maybe custom xorg configuration were causing 390's workaround to not be used? 390's glvnd support is incomplete, and it requires passing a ModulePath option for Xorg, out of the box it'll recognize the nvidia-drm-outputclass.conf Aka it has: Section "OutputClass" Identifier "nvidia" MatchDriver "nvidia-drm" Driver "nvidia" Option "AllowEmptyInitialConfiguration" ModulePath "/usr/lib64/extensions/nvidia" EndSection So it loads glx from /usr/lib64/extensions/nvidia -- but if you have a custom xorg.conf, that may not always work.
I tried with minimal conf, same. I have this OutputClass on the 2 heads of my main card.
