I have a Lenovo ThinkPad E540 with an i5-4200M CPU and HD4600 iGPU and
nVidia GT740M. I tried CURRENT (FreeBSD 11.0-CURRENT #3 r292258: Tue
Dec 15 13:22:31 CET 2015 amd64) with most recent X11 (xorg-7.7_2,
xorg-drivers-7.7_3, xorg-server-1.17.4,1). kldstats reports
Id Refs Address Size Name
1 26 0xffffffff80200000 1245288 kernel
2 2 0xffffffff81447000 7b328 drm2.ko
3 1 0xffffffff814c3000 c98c8 i915kms.ko
so I suppose KMS-capable kernel module for detecting HD4600 iGGPU is up
and running. The notebook has a HD4600/Optimus nVidia GT740M
combination, there is also a firmware switch to select between
"Integrated" (supposedly HD4600) and "Accerlerated" (nVidia Optimus
I'm not able to have a graphical screen either with "intel" or "nvidia"
set in /usr/local/etc/X11/xorg.conf.d/xorg.conf. The Xorg.log reports
about " no device found".
This incident is announced earlier due to the fact I use a vt() based
kernel, UEFI boot and on all systems (with IvyBridge or older) this
method finds the iGPU, reports some properties of the possible ports
available due to i915kms and then switches into a higher resolution
mode instead remaining in that clumsy 640x400 resolution.
Either way what is configured in the firmware (using "Integrated" right
now) I'm incapable of getting any graphical screen or any indication
that the iGPU or the nVidia addemdum GT740M exists.
I read about successfully installed graphical screens on recent
CURRENT with Haswell iGPU graphics - so am I lost with that Optimus
hardware? Or is CURRENT still not handling all Haswell chips?
