Hi.
Ok, I know this wouldn't be a news, rather one more confirmation that laptop with hybrid video (intel+nvidia) can't run pure wayland setup with both cards simultaneously. Works only one - either intel or nvidia, depending on that I specify in WLR_DRM_DEVICES.
Laptop on Intel UHD 630 + NVIDIA RTX 2060 with dual monitors: build-in (intel on eDP) and external (nvidia on DP)
OS: FreeBSD 15.0-RELEASE
And it worth mentioning that X11/Gnome works fine with both monitors.
Out of curiosity, I tried to run a wlroots-based compositor (river 0.4-dev), but under Wayland the PRIME copy path fails — NVIDIA refuses to import DMA-BUF buffers allocated by Intel GBM, both via EGL and Vulkan. Logs suggest sync_file support is missing from the FreeBSD NVIDIA port.
GLES2 renderer, default modifiers
GLES2 renderer, LINEAR modifiers forced
Vulkan renderer + WLR_DRM_NO_MODIFIERS=1 (with default modifiers intel fallback to Y_TILED_CCS and doesn't work)
Just in case, reversing GPU order (card1:card0, NVIDIA as primary) causes river to panic, so that direction is also not viable.
For reference, the same Intel+NVIDIA PRIME copy combination works on Linux (Debian 13), where dma_fence / sync_file infrastructure is available in the kernel.
The Vulkan capability enumeration shows the root constraint for format 'XR24',
Intel Vulkan reports 'LINEAR: ✓ texture ✓ render',
NVIDIA Vulkan reports 'LINEAR: ✓ texture ✗ render'.
This means there is no modifier that both GPUs can agree on for cross-GPU buffer sharing.
In the bottom line seems the DMA-BUF sync_file import/export not supported
Is there any known workaround, or is this a known missing feature in the FreeBSD NVIDIA port?
Has anyone managed to get cross-GPU Wayland compositing working on FreeBSD with hybrid Intel+NVIDIA hardware?
Additional details
