Main specifications (full specs of the laptop) :

  • CPU: 2.4 GHz Intel Core i5-2430M
  • Main memory: 6 GB DDR3
  • Video Graphics (I): AMD Radeon HD 6490M (1 GB DDR5 dedicated)
  • Video Graphics (II): Intel Sandy Bridge GPU
  • Hard disk: 500 GB SATA (5400 rpm)
Wi-Fi drivers:

Compile and install brcmsmac driver from Linux kernel.

KERNEL 
Device Drivers --->
  [*] Network device support --->
    [*] Wireless LAN --->
      < > Broadcom 43xx wireless support (mac80211 stack)
      < > Broadcom 43xx-legacy wireless support (mac80211 stack)
      <M> Broadcom IEEE802.11n PCIe SoftMAC WLAN driver
      < > Broadcom IEEE802.11n embedded FullMAC WLAN driver
  Broadcom specific AMBA  --->
    <M> BCMA support
    [*] Support for BCMA on PCI-host bus

And install the ebuild sys-kernel/linux-firmware to get the required firmware.

SD card reader:

To make sure the integrated SD card reader works fine, your kernel should have:

KERNEL 
Device Drivers  --->
  Multifunction device drivers  --->
    <M> Realtek PCI-E card reader
  <M> MMC/SD/SDIO card support  --->
    <M>   MMC block device driver
    <M>   Realtek PCI-E SD/MMC Card Interface Driver
  <M> Sony MemoryStick card support  --->
    <M>   Realtek PCI-E Memstick Card Interface Driver

Bus options (PCI etc.)  --->
  <*> Support for PCI Hotplug  --->
  [*]   PCI Express Port Bus support     
  [*]   PCI Express Hotplug driver
  [*]   ACPI PCI Hotplug driver
ACPI:

To setup laptop-mode-tools is recommended. Edit the /etc/default/grub file and add this string:

FILE /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor acpi_osi=Linux"

Next, run grub2-mkconfig to update your configuration from that file.

HP and camera drivers:

You can enable the following kernel options (as module o built-in):

KERNEL 
Device drivers --->
    [*] X86 Platform Specific Device Drivers  --->
        <*> HP laptop accelerometer
        <*> HP WMI extras
    Multimedia devices --->
      [*]   Video capture adapters --->
      [*]     V4L USB device --->
      <*>       USB Video Class (UVC)
      [*]         UVC input events device support
    [*] Hardware Monitoring support -->
        <*> STMicroeletronics LIS3* three-axis digital accelerometer

Check the webcam module is loaded:

user $dmesg | grep uvc
uvcvideo: Found UVC 1.00 device USB2.0 UVC HP TrueVision HD (064e:d281)

Check the accelerometer sensor driver for hard disk is loaded:

user $dmesg | grep Accelerometer
input: ST LIS3LV02DL Accelerometer as /devices/platform/lis3lv02d/input/input17

You can test the sensor by moving your laptop and checking the output of this command: 

watch -n 1 'cat /sys/devices/platform/lis3lv02d/position'

See HPfall for more information about hard disk protection.

Portage:

Some values to config portage for this laptop:

FILE /etc/portage/make.conf
CFLAGS="-march=corei7-avx -O2 -pipe"
CPU_FLAGS_X86="mmx mmxext sse sse2 sse3 ssse3 sse4 sse4a sse4_1 sse4_2"
MAKEOPTS="-j5"
VIDEO_CARDS="intel i965 radeon"
GRUB_PLATFORMS="pc

Graphics and video decoding:

The laptop includes an Intel Sandy Bridge integrated GPU that supports VA API and works with intel opensource driver and AMD 6490M discrete GPU that works with radeon or fglrx drivers. Sadly, VA API standard is not recognize for many applications, but you can install the great libvdpau-va-gl library from several overlays to get the video decoding by hardware works for VDPAU, a standard more extended. Currently (end-2013) Mozilla Firefox doesn't support a way to configure its gstreamer-backend to use VA API. See this blog entry: VA API Backend for VDPAU

For basic usage, intel driver works fine. Portage configuration:

FILE /etc/portage/make.confConfig for the intel driver
VIDEO_CARDS="intel i965"

Touchpad and keyboard layout config:

Make a /etc/X11/xorg.conf.d/20-input.conf to config the synaptics touchpad and keyboard layout (in my case, Spanish)

FILE /etc/X11/xorg.conf.d/20-input.conf
# Xorg configuration: mouse
Section "InputClass"
    Identifier   "MyTouchpad"
    MatchIsTouchpad   "on"
