NVIDIA 435.17 Linux beta driver has added Vulkan and OpenGL+GLX support for PRIME render offload. Additionally if you are using an Intel IGP you might be able to fix the GL Compositing issue by running the IGP as UXA instead of SNA, however this may cause issues with the offloading process (ie, xrandr --listproviders may not list the discrete GPU). When using PRIME Render Offload, selected 3D applications can be rendered on the Discrete GPU and sent to the Integrated GPU, which displays the image. This may reduce your battery life and increase heat though. From my experience trying to get Prime render offload working in 18.04, I know of a way to put it in Intel mode and have the nVidia turned off (using bbswitch, a third-party program). Bumblebee guys, try PRIME render offload. To improve this situation it is possible to do the rendering by the discrete NVIDIA card, which then copies the framebuffers for the LVDS1 and VGA outputs to the Intel card. The provider and sink identifiers can be numeric (0x7d, 0x56) or a case-sensitive name (Intel, radeon). Added support for "Reverse PRIME Bypass", an optimization that bypasses the bandwidth overhead of PRIME Render Offload and PRIME Display Offload in conditions where a render offload application is fullscreen, unredirected, and visible only on a given NVIDIA-driven PRIME Display Offload output. combination with dynamic power management to leave an NVIDIA GPU While __NV_PRIME_RENDER_OFFLOAD=1 tells GLX or Phoronix: NVIDIA 435.17 Linux Beta Driver Adds Vulkan + OpenGL PRIME Render Offload NVIDIA this morning introduced their 435 Linux driver series currently in beta form with the release of the 435.17 Linux build.
