Thanks so much! Sigh, after all the discussion and problem / fix reports (mostly on the freebsd-x11@ list, which I'm adding to Cc) about the "new DRM" stuff, one would think that there should be some simple-to-follow *FreeBSD* web page that explained it all and could be pointed to if not immediately found. There is https://wiki.freebsd.org/Graphics, which IMHO is neither simple to find nor to follow, and which still has the broken-with-12.1 "pkg install drm-kmod" advice. I think it is sad, since there's a lot of great work that has gone into this - personally I have a laptop that wouldn't have had *any* graphics (on FreeBSD) without it, and I know I'm not alone in that. Anyway, enough ranting - if you look at the "Intel Integrated Graphics (aka HD Graphics)" section on the above page, and specifically the "Example Configuration For Post Broadwell System", and *skip* the bad pkg advice, you'll find that the next step is to add kld_list="/boot/modules/i915kms.ko" to rc.conf - and actually the "post-install package message" will have told you so, but yeah, who reads those things... The problem (not explained anywhere that I can find right now) is that after building and installing the drm-kmod port (or package), you have *two* drivers called i915kms installed. One is part of the base system, /boot/kernel/i915kms.ko - this is the one that doesn't work for you (or me), and gets loaded if you do "kldload i915kms". The other is from the port that you installed, and it's the above /boot/modules/i915kms.ko - you must ensure that this is the one that is loaded. The above line makes sure that this happens at reboot (loading via boot/loader.conf has been reported to *not* work in at least *some* cases, and there's no advantage over loading via /etc/rc.conf), but you can also do it manually for testing, by using the full path with "kldload": kldload /boot/modules/i915kms.ko Read and follow also the subsequent steps in the example, as well as the "Note:" at the end of the section. If your card is actually supported (and frankly I'm not sure how to figure that out in any other way than trying it), you should be fine at that point. --Per Hedeland
