Hi Michael, good suggestion, I tried the "official" nVidia driver and it would, unfortunately, just plainly reset my whole system (no panic, just a complete reset) when trying to start X. ;-) But in other news, my latest research results: 1) The "nv" driver, before leaving my screen in an "unrsponsive" (but indeed ssh-reachable state) seems to start up normally, but then complains about: "NV(0): Failed to determine the amount of available video memory" I'm unsure, but when I look at this: https://github.com/mkottman/acpi_call then it seems entirely possible that this dedicated card first has to be enabled by means of some ACPI call before it can be used. So...: 2) I shifted my focus on the "intel" GPU and driver instead. That one seems to be active at boot by default, I've tried it with Linux: The Intel GPU on my machine is no problem there, but the nVidia thing makes headaches too. So, like I said, I focussed on the Intel GPU and found the following: http://forums.freebsd.org/showthread.php?t=15686 which in turn links to: http://www.dragonflybsd.org/docs/developer/GEMdrmKMS/ Quote: "It is especially vital for Linux drm GEM, TTM, KMS code to be ported immediately to the BSDs because developers are in the process of removing userland modesetting code from current graphics drivers." And indeed, now I remember something: The "default" Intel X11 drivers that the ports collection wanted to install (xf-video-intel) didn't yet know my specific Intel GPU and thus wouldn't recognize it. So I installed "xf86-video-intel29", which had a IGNORE line stating "Waiting for GEM", which I did just override. So I guess I can try as long as I want to, I won't have too much success until this stuff is actually ported to FreeBSD so that "xf-video-intel29" (or a subsequent version) is actually usable. Question: I'm on 8-STABLE currently, if I switched my machine to -CURRENT for a moment, would I already find enough GEM / KMS stuff in there that I would at least have a remote chance to get my card to work and could probably even provide input / testing for the porting process? Or is the GEM / KMS stuff so far away that I should better stay away from it for the time being? Greetings, Nils
