Configuration
kernel boot parameters
To let kernel bootable, acpi workable, and CPU on demand. These pararmeters should be added into boot loader kernel option (eg. grub).
acpi_osi=Linux intel_pstate=disable
CPU
Follow the CPU Frequency Scaling guide to enable speed-stepping. Processor has Intel Turbo Boost which works out of the box, but you can't see the frequncies above 2.5GHz in /proc/cpuinfo. To see the actual frequency use i7z package.
- energy save: cpupower (800Mhz-2.5Mhz)
Video
Intel
Follow these guides: Xorg and Intel
VGA out: workable by xrandr settings.
Not tested: HDMI.
Audio
Follow the official documentation: ALSA and Pulseaudio
In order to make integrated speakers work add to /etc/modprobe.d/modprobe.conf
:
options snd-hda-intel index=0 model=auto
And to /etc/modprobe.d/sound.conf
add:
alias snd-card-0 snd-hda-intel alias sound-slot-0 snd-hda-intel
Touchpad
- Follow the Synaptics guide.
- Disable touchpad upon external mouse detection
Webcam
Install cheese(with gstreamer-0.10-plugins) to view.
