[-- Attachment #1 --] nVidia's BLOB from port x11/nvidia-driver seems to have problems in FreeBSD 11.0-CURRENT #2 r271869: Fri Sep 19 13:28:03 CEST 2014 amd64, on Lenovo ThinkPad Edge E540 laptop with CPU i5-4200M (Haswell) with integrated HD4600 Intel iGPU and dedicated nVidia GT 740M (Optimus) working correctly. The systems boots FreeBSD off via UEFI. First of all: I tried versions 340.24, 340.32 and Beta 343.13 all with the very same results. Symptoms: a) Loading kernel module "nvidia" via /boot/load.conf freezes the system after the UEFI/EFI loader message shows up. Loading the kernel module vi kld_load= in /etc/rc.conf[.local] works so far regarding loading and booting the kernel. b) No display socket is recognized by the nvidia driver resulting in a blank vt() screen after X has been started. I tried many different configurations, but at the end I suspect that nVidia's "Optimus" technology may be the culprit. The documentation of nVidia's driver for FreeBSD states that after the Xserver has started it logs in Xorg.0.log (or whatever display number is used) the available display sockets like (taken from the documents): (--) NVIDIA(0): Valid display device(s) on Quadro 6000 at PCI:10:0:0 (--) NVIDIA(0): CRT-0 (--) NVIDIA(0): CRT-1 (--) NVIDIA(0): DELL U2410 (DFP-0) (connected) (--) NVIDIA(0): NEC LCD1980SXi (DFP-1) (connected) Nothing that similar shows up in my environment, but this: [...] [ 58.656] (--) PCI:*(0:0:2:0) 8086:0416:17aa:502a rev 6, Mem @ 0xf1000000/4194304, 0xe0000000/268435456, I/O @ 0x00006000/64, BIOS @ 0x????????/65536 [ 58.659] (--) PCI: (0:1:0:0) 10de:1292:17aa:502a rev 161, Mem @ 0xf0000000/16777216, 0xc0000000/268435456, 0xd0000000/33554432, I/O @ 0x00005000/128 [ 58.662] (II) "extmod" will be loaded.

The more scaring part is then (--) NVIDIA(0): Valid display device(s): No display device is shown although the notebook has a built-in display, a DisplayPort port as well as a VGA port. On all nVidia dedicated graphics boards I use on diffrent other machines with the very same driver EVERY possible connector/socket shows up. The laptop has EFI/UEFI EFI Version: 2.31 EFI Firmware: Lenovo (re. 05648) The problem is present no matter whether the drm2 and i915kms kernel moules are loaded or not. What is wrong here? Any chance to get the nVidia GPU to work? I use at the moment xf86-video-scfb which is a pain in the ass and absolutely not usable, even with a faster CPU. Under average load the whole laptop screen is like a slide show. Please CC me. Thanks in advance, O.
