On NetBSD 9.99.108 amd64 on a laptop, if I disable i915drmkms module I am able to do startx. However then I do not get HDMI output.
With the DRMKMS driver disabled, you'll get `genfb' which is just a dumb framebuffer driver. There's no HDMI with this. Only the primary display will work with the genfb/wsfb (the Xorg driver which you'll very likely be getting) combo.
With i915drmkms enabled I can get HDMI output but then I don't get X11 and dmesg shows Asynchronous wait on fence i915drmkms0:X[17637]:2 timed out (hint:0xffffffff8075ce30)
Try the `modesetting' Xorg driver instead of `intel' and make sure the GPU firmware blobs are present in /libdata/firmware/i915drmkms. Get these from here: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915 The blobs should finally have a path like: /libdata/firmware/i915drmkms/i915/something.bin $ cat /etc/X11/xorg.conf.d/modesetting.conf # Depends on kernel DRM # Section "Device" Identifier "Card0" Driver "modesetting" # Option "SWcursor" "on" # Option "ShadowFB" "off" # Option "AccelMethod" "none" EndSection $ -RVP
