Thank you for the continued assistance.
I have now altered my /etc/rc.conf to have `kld_list="i915kms"` (I removed the .ko)
Running `kldstat` lists the following:
Id Refs Address Size Name
1 29 0xffffffff80200000 1fa8888 kernel
2 1 0xffffffff82221000 978bd i915kms.ko
3 1 0xffffffff822b9000 55180 drm2.ko
4 4 0xffffffff8230f000 26e8 iicbus.ko
5 1 0xffffffff82312000 1c75 iic.ko
6 1 0xffffffff82314000 1e70 iicbb.ko
7 1 0xffffffff82316000 2a05 uhid.ko
8 1 0xffffffff82319000 3710 ums.ko
9 1 0xffffffff8231d000 155b2 ext2fs.ko
After starting Xorg I unfortunately see the falling back to software rendering message and when I run `glxinfo | grep Device` I get: Device: llvmpipe (LLVM 3.7, 256 bits) (0xffffffff)
Is there anything else I can try, or any further details I can provide?
Thank you & regards,
