I’m testing Red Hat Enterpise Linux 9.6 and while it works fine with an Intel and and AMD graphics card, I cannot use 3D acceleration inside an Xvnc with the nVIDIA card. The Red Hat support tells me that they cannot help me, because the nvidia driver comes as closed source binary. I’m wondering if it’s worth trying a different binary, like a -latest oder -open from the CUDA repository or if they are all lacking some feature related to /dev/dri/renderD128. If they are lacking some feature, might it be worth testing with a later version or is it a “won’t fix”?
Steps to reproduce: dnf install tigervnc-server tigervnc vncserver vncviewer :1 inside the viewer: glxinfo -B It will show MESAs llvmpipe (meaning software rendering), whereas for Intel and Radeon card it will show the GPU.
I tried an RTX A5000 with akmod-nvidia-570.172.08-1.el9.x86_64.
