HAVE IN MIND: FreeBSD is a SERVER OS.
May work on some laptops. May not. Is not designed to low power management, or work with everything a laptop has. Need a lot of tweaking, a lot of patience and a lot of tests to do it workable. Some things will work but not with the obvious way.
This is not Linux and to put it into a laptop with a list of devices and battery, make it more difficult because except the fast battery drain, you should do it work to economy / performance mode when you unplug / plug the charger.
This tutorial is specific for Lenovo P400 touchpad and may not work everything on other Laptops. Even on other Lenovo models.


Trying to make my laptop to work with FreeBSD, I am going to start a tutorial.
I will post every progress I make and everything works/will work.

It is 10.1-RELEASE with the Gnome 3 desktop environment.

SSD

Installation on SSD: https://forums.freebsd.org/threads/is-this-the-right-setup-for-ssd.50358/

Also we can install the system normal on UFS and enable trim support from single user mode with this command:

Code:
tunefs -t /dev/adaXpX
(ada0p2 on my ssd)

Power Management (The big problem)

Add this on /boot/loader.conf

Code:
hint.p4tcc.0.disabled="1"
hint.acpi_throttle.0.disabled="1"
drm.i915.enable_rc6=7
and this on /etc/rc.conf

Code:
performance_cx_lowest="Cmax"
economy_cx_lowest="Cmax"
powerd_enable="YES"
powerd_flags="-a hadp -b adaptive -i 50 -r 75"
Sound

Add this line to /boot/loader.conf

Code:
snd_ich_load="YES"
snd_hda_load="YES"
For some reason need both of them to work properly

Graphics. Works perfect with right resolution

Build this: x11-drivers/xf86-video-intel and multimedia/libva-intel-driver

No need to create xorg.conf file

Mouse and Keyboard

Add this on /etc/rc.conf

Code:
hald_enable="YES"
dbus_enable="YES"
and build / rebuild from ports:

http://www.freshports.org/x11-drivers/xf86-input-mouse
http://www.freshports.org/x11-drivers/xf86-input-keyboard

Microphone

Works by default on 10.1-RELEASE

Headphones

Works by default on 10.1-RELEASE

Ethernet

Works by default on 10.1-RELEASE

This is my configuration on /etc/rc.conf

Code:
ifconfig_re0="inet 192.168.1.20 netmask 255.255.255.0"
defaultrouter="192.168.1.1"
Brightness

It was big surprise for me.

Add this lines into /boot/loader.conf

Code:
acpi_ibm_load="YES"
acpi_video_load="YES"
And this lines to /etc/sysctl.conf

Code:
hw.acpi.video.lcd0.brightness: 100
hw.acpi.video.lcd0.fullpower: 100
hw.acpi.video.lcd0.economy: 20
Logout Problem

You must build your kernel with the new console driver. Newcons.
See here: https://wiki.freebsd.org/Newcons

and add this line in /boot/loader.conf

Code:
hw.vga.textmode=1
Camera

My second big surprise. On gnome3 , cheese works!

Install from ports

http://www.freshports.org/multimedia/webcamd/
http://www.freshports.org/multimedia/cuse4bsd-kmod/

On /etc/rc.conf add

Code:
webcamd_enable="YES"
On /boot/loader.conf add

Code:
cuse4bsd_load="YES"
On /etc/devfs.conf add

Code:
perm video0 0666
The problem is that if you take a screenshot, picture is not saved on /home/.gnome2/cheese/media.
Also camera stops working so you must restart cheese application
I will search about this later.

FN KEYS

  • Brightness works. See Above how.
  • For Volume. Up and down works by default.
  • PrintScreen too.
  • To Make mute works too:

Go to gnome3-settings -> Keyboard -> Shortcuts -> Sound and Media and give a key combination for Volume Mute.

Something similar exists on other Desktop Environments too

Remove Beeps

See here: https://forums.freebsd.org/threads/cannot-make-system-bell-stop.50410/#post-282351

Wifi

Worked updating to 11-CURRENT

Suspend - Resume

Gnome 3 suspend is not working.

But

sudo apm -z

Easy and fast. No configs, no problems!

Temperatures

Add this line to /boot/loader.conf

Code:
coretemp_load="YES"
You can see the temperatures by this command:

sysctl -a | grep temperature

Output

Code:
hw.acpi.thermal.tz0.temperature: 41.0C
dev.cpu.0.temperature: 40.0C
dev.cpu.1.temperature: 40.0C
dev.cpu.2.temperature: 44.0C
dev.cpu.3.temperature: 44.0C
dev.cpu.4.temperature: 43.0C
dev.cpu.5.temperature: 43.0C
dev.cpu.6.temperature: 47.0C
dev.cpu.7.temperature: 47.0C
DVD-RW Drive

Add this lines on /boot/loader.conf

Code:
atapicam_load="YES"
cd9660_load="YES"
And this lines into /etc/devfs.conf

Code:
link cd0 cdrom
link cd0 dvd
perm cd* 0666
perm xpt* 0666
perm pass* 0666
USB2 - USB3

Works by default on FreeBSD 10.1

Please only use Xorg -configure when necessary. It produces poor configuration files and is usually not necessary.

I test it. You have right. xorg.conf file is not needed.
