HP Pavilion dv6520ea

From Gentoo Linux Wiki

[edit] Introduction

Booting Gentoo 2007.0

The pavilion dv6520ea is a mid-end laptop, and costs around ~800€. It is available in two configurations: one with intel's x3100 and one with nvidia's 8400m. This tutorial is for the intel version, but it should be pretty more the same for the nvidia version, except X.org configuration.

[edit] Specs

[edit] What doesn't work

• The 56k modem
• XpressCard slot (I don't have such a card to test if it works)
• Brightness control
  Warning: You cannot set brightness in any way. vbetool doesn't set it, and if you set it from windows, it's cleared in linux boot.
  Note: Brightness is changed though when you plug/unplug power cord.
• Keyboard leds
  Note: When you are logged in in a framebuffer'ed console, and get a kernel panic, caps led starts blinking.

[edit] Battery life

Frequency scaling should be used. Using the ondemand governor, and with *normal* usage, including wifi, it should last for ~2hrs for the 6-cell battery, and ~5hrs for the 12-cell battery (which is available as an accessory. If you are doing a x86 installation, be sure to install and experiment with intel's powertop (see reference section).

[edit] Installation procedure

Installation has a tricky part. Because 2007.0 cds do not see neither the wired ethernet nor the wireless ethernet, you have two options:

1. download needed installation files
2. use another livecd (ie ubuntu, knoppix)

I preffer the 1st way, since the other 2 distros I like (slack, which doesn't have a livecd and ubuntu) do not play ok with this hardware.

[edit] make.conf

You 'll have to configure the rest of /etc/make.conf options (GENTOO_MIRRORS,SYNC,LINGUAS,etc) by yourself.

[edit] CFlags

See CPU section.

[edit] USE flags

hal, lm_sensors, acpi, dri, posix, threads, wifi, dvdread, cdr, usb, opengl, alsa, -oss, bluetooth

[edit] Other

ALSA_CARD="hda-intel"
VIDEO_CARDS="vesa intel i810"
INPUT_DEVICES="keyboard mouse evdev synaptics"

[edit] Required files

Procceding with the installation.
If you choose installation method 1, here are the files you 'll need (or newer ones if there are available):

genpatches-2.6.22-3.base.tar.bz2
genpatches-2.6.22-3.extras.tar.bz2
genpatches-2.6.22-6.base.tar.bz2
genpatches-2.6.22-6.extras.tar.bz2
genpatches-2.6.22-7.base.tar.bz2
genpatches-2.6.22-7.extras.tar.bz2
genpatches-2.6.22-9.base.tar.bz2
genpatches-2.6.22-9.extras.tar.bz2
gentoo-headers-2.6.22-3.tar.bz2
gentoo-headers-2.6.22.tar.bz2
grub-0.97-patches-1.0.tar.bz2
grub-0.97-patches-1.4.tar.bz2
grub-0.97.tar.gz
linux-2.6.22.tar.bz2
splash.xpm.gz
r8101-1.004.00.tar.bz2 (realtek's driver module for the r8101e. can get it from here
r8101-1.005.00.tar.bz2 (only this version compiles on >= 2.6.23. it's not available for download, email me if you want it.

Copy all the files above in /usr/portage/distfiles, and follow the manual. When you are asked to installed the kernel, issue emerge =gentoo-sources-2.6.22-r8. Do not install anything else but grub.
After booting to the new installation, install the r8101 driver module, configure your network, and you are ready.

[edit] Hardware configuration

Most of the hardware used in this laptop is not new, so you won't have any difficulties configuring it.

[edit] CPU

See this HowTo.

[edit] Graphics

See this guide.

[edit] Audio

If you built alsa into the kernel, you 'll have the problem that alsa works ok, but the sound card is always muted, and can't be unmuted. You will have to use the alsa modules provided outside the kernel.

emerge alsa-headers
emerge alsa-driver
merge alsa-utils

 Device Drivers  --->
  Sound --->
   <M> Sound card support
    Advanced Linux Sound Architecture --->
     < > Advanced Linux Sound Architecture
    Open Sound System --->
     < > Open Sound System (DEPRECATED)

[edit] Webcam

You need 3rd party software to use the webcam.

emerge linux-uvc
modprobe uvcvideo

You 'll check a new device at /dev/v4l/video0. Use uvcview to get content from the camera.

      <M> USB SN9C1xx PC Camera Controller support
      <M> USB ZR364XX Camera support

[edit] QuickPlay touch keys

You need to remap the keys to work with xmodmap. These are the key codes to put in /etc/X11/Xmodmap:

keycode 144 = XF86AudioPrev
keycode 162 = XF86AudioPlay
keycode 153 = XF86AudioNext
keycode 164 = XF86AudioStop
keycode 160 = XF86AudioMute
keycode 174 = XF86AudioLowerVolume
keycode 176 = XF86AudioRaiseVolume

[edit] Wireless

See this guide.

[edit] Framebuffer

Works ok for 1024x768. Append to /boot/grub/grub.conf:

vga=0x318

or

vga=792

 Device Drivers  --->
  Graphics support --->
   <*> Support for frame buffer devices
   <*> VESA VGA graphics support
    VESA driver type (vesafb) ---> #If you plan to run X.org, do not use vesafb-tng. It breaks console switching when using <Ctrl><Alt>F1-6

   [*] DDC/I2C for Intel framebuffer support

[edit] Memory card reader

Works like a charm. If you don't have automatic module loading enabled,

modprobe mmc_block

I have tested it with mmc, sd and ms pro.

[edit] Bluetooth

Works quite good. Unfortunately, has a lot of stuff depending on gnome (or kde, whatever you choose. Less stuff on gnome version though).

emerge gnome-bluetooth
emerge bluez
emerge openobex
emerge bluetooth-applet

[edit] ACPI

This CPU supports frequency scalling and some other nice features. You have to turn on the acpi USE flag from the beginning.

emerge acpid
rc-update add acpid default

   <*> Intel Enhanced SpeedStep (deprecated)
   <*> ACPI Processor P-States driver
   [*] /proc/acpi/processor/../performance interface (deprecated)

[edit] Fingerprint scanner

You have to use fprint. Unfortunately, this is not in portage yet. You have to create a custom overlay.

mkdir -p /usr/local/portage/bioapi/app-misc/fprint_demo
cd /usr/local/portage/bioapi/app-misc/fprint_demo
wget http://www.reactivated.net/fprint/ebuilds/fprint_demo-0.4.ebuild
ebuild fprint_demo-0.4.ebuild digest
mkdir -p ../../media-libs/libfprint
cd ../../media-libs/libfprint/
wget http://www.reactivated.net/fprint/ebuilds/libfprint-0.0.4.ebuild
ebuild libfprint-0.0.4.ebuild digest
mkdir -p ../../sys-auth/pam_fprint
cd ../../sys-auth/pam_fprint
wget http://www.reactivated.net/fprint/ebuilds/pam_fprint-0.2.ebuild
ebuild pam_fprint-0.2.ebuild digest
echo PORTDIR_OVERLAY=\"/usr/local/portage/bioapi/\" >> /etc/make.conf # or edir apropriately if you already have other custom overlays
emerge libfprint pam_fprint fprint_demo
...
vim /etc/pam.d/system-auth
 in the second line add: auth sufficient pam_fprint.so

[edit] Touchpad enhancement

emerge synaptics

Synaptics has a daemon which will allow you to deactivate the touchpad while typing, so you don't accidentaly touch it.

synd -d -i 1

Where -d is daemonize, and -i the time interval that has to pass before it activates the touchpad again, in seconds.

[edit] Application configuration

• Example X.org configuration for 1-head: here
  
• Example X.org configuration for 2-head: here
  
• Audio recording: To use the onboard stereo mics, for recording select Front mic and experiment with Front mic boot and Capture mixers
• kismet: source=ipw3945,eth1,ipw3945

[edit] Known issues

• On kernels <= 2.6.21-r4, if you have the wireless switch to off while booting, you get a terminal lock-up.
• On kernels <= 2.6.19-r5, I didn't get DRI to work.
