From Gentoo Linux Wiki

[edit] Gentoo on an HP Pavilion dv1000

The dv1000 is a great laptop. Sporting an Intel Pentium M processor along with ultra-low-voltage Centrino Technology, a crisp 14.1" TFT Display, great battery life, excellent Harman/Kardon speakers, a built in Intel 2200 Pro/Wireless Lan card, a wireless remote, and DVD QuickPlay; this laptop is aesthically pleasing, light, and fast making it great for travelers, businessmen, and students.

[edit] Introduction to this Guide

This is not a guide on how to install Gentoo (for help with that see the Gentoo Handbook), but rather a report on the non-trivial steps used to take full advantage of the laptop's hardware. As this is a gentoo-wiki this guide will focus on installation in a Gentoo environment, but everything explained here should apply to other Linux distributions as well.

It is a bit of a hassle to make everything work correctly under Linux, but it is well worth it and this guide should make it much easier. Everything that works out of the box is more or less omitted (for obvious reasons). Everything else that requires some configuration I try to at least mention. Keep in mind these were only the steps I took in order to get things working. I am by no means an expert of hardware in Linux so you may find better solutions than the ones presented here. If you do please edit this guide so that other people may benefit as well.

[edit] Documentation

The only documentation you are going to find for the dv1000 is the (Maintenance and Service Guide) from Compaq's website. It has some useful information regarding hardware starting at page 173. Despite the fact that HP claims to support Linux, my experience with their tech support team and their (Linux Website) has suggested otherwise. This is a response I got from HP's "tech" support in regards to a simple question regarding their cpqhealth driver.

Thank you for contacting HP Total Care.

I like to inform you that the we here provide technical support through
email for all HP Pavilion Notebook models and HP does not support any
Operating system other than the preinstalled one.

Partially

• Digital Media card reader

You need kernel 2.6.17, check [1] for detailed instructions

Not Working

• LM Sensors

USB Issues

• Several people have reported that the USB port just above the DVD drive seems to only work occasionally. Most of the time if something is plugged in the device won't be recognized (no LED on an optical mouse for example). Every once in awhile, however, the port seems to work flawlessly. If anyone has found a solution to this please let us know.

[edit] Getting Started

Now before you get all gung ho and completely nuke the Windows partition, make sure to update your bios to the newest version.

As I said before this is not a guide on how to install Gentoo linux - for that just follow the Gentoo handbook - but we'll take a brief aside to configure the USE flags relevant to the Intel Pentium M Centrino CPU.

To find out some information regarding your CPU just do a:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 13
model name      : Intel(R) Pentium(R) M processor 1.70GHz
stepping        : 6
cpu MHz         : 1695.804
cache size      : 2048 KB
physical id     : 0
siblings        : 1
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2
wp              : yes
flags           : fpu vme de pse tsc msr mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe est tm2
bogomips        : 3366.91

and as you can see you will want to at least add acpi, mmx, and sse to your USE in make.conf.

On the subject of USE flags, I highly recommend using gcc 3.4.4 or better as it will compile your programs specifically for a Pentium M rather than treat it as a Pentium 3.

(For more information regarding USE flags try organized / sorted USE flags at Gentoo Forums)

[edit] Kernel Configuration

I used Gentoo-Source v2.6.11r11, although Vanilla 2.6.10 sources also work well. Whatever you do make sure you use a kernel >=2.6.9, since it deals much better with Pentium M CPUs. Throughout this guide, I'll assume you are using such a source.

A sample kernel configuration that includes pretty much everything. An entire .config file (2.6.14-gentoo-r5) can be found here.

[edit] LM Sensors

LM Sensors does not work, as Compaq/HP uses proprietary chips and will not release their data sheets. A driver does exist for their chips (cpqhealth) so that one can monitor the internal system, however Compaq/HP claims cpqhealth only runs on Compaq Proliant Servers with a 2.4 kernel. I would imagine, however, that it is possible to get cpqhealth running on any system with a 2.4 kernel as you could just download the rpm and use alien to convert the package.

Now if for some reason you are running a 2.4 kernel and get cpqhealth installed, it would technically be possible to use a wrapper and the binary to get it to work on a 2.6 kernel (you would have to port the wrapper). So IF you are running a 2.4 kernel, and IF you get cpqhealth installed, and IF you write and port the wrapper, the modules that need to be ported are the opt/compaq/cpqhealth/[cmhp,cqpasm,cpqevt].

If you do not want to do that it is still possible to get some data from the system (no fan information though)

To check the current CPU temperature:

temperature:             61 C

To check the status of the battery:

present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            0 mA
remaining capacity:      7424 mAh
present voltage:         12438 mV

[edit] Cpu Frequency scaling

Check than you have some files that start with cpuinfo_ and scaling_ in the direcory /sys/devices/system/cpu/cpu0/cpufreq;

If you don't then you probably need to mounted your /sys or don't have <sysfs> support in your kernel configuration. (Check if acpi-cpufreq module is loaded.) The next thing that needs to be done is to choose a daemon to dynamically control the CPU frequecy. cpufreqd is popular as it is simple to configure and changes frequency quickly. speedfreq is also very nice, however it is now masked in portage. So whatever you choose, just emerge and add it to the default runlevel.

emerge cpufreqd
rc-update add cpufreqd default

[edit] Wireless Lan Configuration

[edit] Intel 2200 Pro/Wireless Lan

Intel PRO/Wireless 2200BG Driver for Linux project website.

ipw2200 is now built into the kernel (2.6.14), however if you prefer to use the portage driver, that is okay too.

The card is now fully supported under linux (the LED even works). A standard emerge will get you the latestest stable driver/firmware that you need.

If you prefer the latest driver (or are getting weird errors when trying to install) then we need to make portage play nicely.

• 1. We need to unmask some packages so add these lines to our /etc/portage/package.keywords file. (If this file doesn't exist just create it.)

echo "net-wireless/ipw2200-firmware ~x86" >> /etc/portage/package.keywords
echo "net-wireless/ieee80211 ~x86" >> /etc/portage/package.keywords
echo "net-wireless/ipw2200 ~x86" >> /etc/portage/package.keywords

• 2. Fetch the new packages, but don't emerge them yet.

# emerge -af ipw2200 ipw2200-firmware ieee80211

[ebuild  N    ] net-wireless/ipw2200-1.0.6
[ebuild  N    ] net-wireless/ipw2200-firmware-2.3
[ebuild  N    ] net-wireless/ieee80211-1.0.3

• 3. Unmerge the old packages.

emerge -aC ipw2200 ipw2200-firmware ieee80211

• 4. (From /usr/share/doc/ipw2200-1.0.6/README.ipw2200.gz once you emerge the packages) "We need to make sure that our system doesn't have any old versions of the drivers that could be found by modprobe instead of the new version. So we need to delete anything found by:"

cd /usr/src/linux
# for i in ieee80211 ipw2200; do find /lib/modules/`uname -r` -iname ${i}*; done

• 5. Emerge the new packages.

emerge ipw2200 ipw2200-firmware ieee80211

• 6. Load the modules automatically at startup (and turn the LED on):

echo "ipw2200 led=1" >> /etc/modules.autoload.d/kernel-2.6

• 7. Load and use the new modules.

rmmod ipw2200 && modprobe ipw2200 led=1

Several people have reported issues with losing their wireless connection frequently. This for obvious reasons is undesirable and having to restart dhcpcd every couple minutes is maddening.

If this is happening:

• 1. Update the firmware on your Dlink, Linksys, Netgear, or appropriate router.
• 2. Try a newer driver version.
• 3. Change the channel of your router.

Another option worth trying is to add "hwcrypto=0" to modprobe and modules.conf to disable cryptographic acceleration. It doesn't make much difference anyway, as far as CPU usage is concerned. For some people it solves "firmware error" issues at once.

[edit] Broadcom Corporation BCM4306 802.11b/g Wireless card

See the Broadcom 43xx article.

[edit] Graphics

See this HowTo.

[edit] Sound Mixing with Alsa

The intel8x0 supports sound mixing. Depending on your window manager you may or may not have to setup sound mixing. I believe with KDE sound mixing is done automatically via arts but with other window managers such as fluxbox it is not. Alsa is the obvious choice for mixing but you could use dmix, ESD, arts, or OSS. I direct you to the sound mixing wiki for the complete details. Pretty much just follow #3 "Setting up alsa" on the table on contents and you are all set.

[edit] Function/Media Keys and Remote Control

The touchpad on/off button does not work with fluxbox. In fact I can not even get a valid keycode for it. It may work with a desktop environment such as Gnome/KDE or it may be part of the Synaptics touchpad driver but I am unsure. So if you are using Gnome/KDE and know the keycode please post it.

The media keys and remote control buttons currently don't have any operations associated with them. This is easy enough to change and I direct you to the HOWTO Use Multimedia Keys wiki for more information. For convenience I have listed all the unmapped keycodes below. Important note: pressing the tv button (lower right button on the remote) completely scrambles my display and the only way I have found to recover from this is via ctrl + alt + backspace. If anyone knows how to correct this please let us know. (You can also press ctrl + alt + f1 to get to a text mode and then ctrl + alt + f7 to get back to X)

Alternately, you can download a very useful program called xbindkeys. It's fairly straight forward and a quick read of the man page is all you'll need, just be sure to load your configuration when you start X. For example you could edit your ~/.xinitrc and add a line that reads xbindkeys & before the line that executes your window manager:

[edit] Text Mode

If you don't use X you can still remap your keys, you just have to edit your keymap; first, lets work on the copy of the one you use (must be root):

# cp /usr/share/keymaps/i386/qwerty/<yours> ./newkeys.map.gz

Unpack it and run showkey to see the codes associated to the key(s) you want to bind; let's say you want to bind the code 155 to the command "amixer set Master 1+": you have to append two lines to newkeys.map like this:

keycode 155 = FXY
string FXY = "amixer set Master 1+"

When you're done adding bindings, you have to pack back the file and move it to /usr/share/keymaps/i386/qwerty/newkeys.map.gz

gzip newkeys.map
mv newkeys.map.gz /usr/share/keymaps/i386/qwerty/newkeys.map.gz

and see if it works. If it does, you can edit the KEYMAP variable in /etc/rc.conf to point to newkeys.

[edit] Framebuffer

[edit] Vesafb

This framebuffer is almost fully supported. Getting a framebuffer resolution of 1280x768 isn't possible (at least by default). It may be possible to edit the /etc/fb.modes to implement this, however.

Two available frame buffer programs exist for Gentoo: fbsplash and bootsplash.

• The tutorial on setting up fbsplash is HOWTO gensplash.
• The tutorial on setting up bootsplash HOWTO Framebuffer:Bootsplash:Grubsplash.

[Relevant grub.conf]

kernel /kernel.buffer root=/dev/hda6 CONSOLE=/dev/tty1 vmalloc=32m gentoo=udev devfs=nomount vga=791 splash=verbose,theme:emergence

The framebuffer also works fine on HP Pavilion ZE2010 (same card) with Kernel 2.6.12-gentoo-r4. Just unmerge and re-emerge splashutils, and then rebuilt the framebuffer file with splash_geninitramfs.

[Relevant grub.conf]

kernel /boot/kernel-2.6.12-gentoo-r4 root=/dev/hda1 video=vesafb:ywrap,mttr,1024x768-16@60 splash=silent,fadein,theme:livecd-2005.0 quiet CONSOLE=/dev/tty1

[edit] Vesafb-tng

The replacement for vesafb works just fine on a dv1266EA (pretty much the same hardware save for hard-drive and RAM). Just select vesafb from the kernel and then select vesafb-tng from the item just right under it. The default resolution can be set to "1280x768@60". It worked right out of the box.

[edit] Intelfb

Currently the Intelfb does not fully support Local Flat Panels (ie. LCD screens), only CRT output (ie. external monitors) so it cannot be used on a laptop. (Keep an eye on Sylvain Meyer and the progress he is making with the Intelfb though.)

[edit] Touchpad Configuration

The touchpad will work out of the box, but configuring it gave me a bit of trouble. I direct you to HARDWARE Synaptics Touchpad for the details, but here are the settings that worked for me:

Section "InputDevice" #touchpad
Identifier "Touchpad"
   Driver "synaptics"
   Option "SendCoreEvents"
   Option "Device" "/dev/input/event1" # eventX number may vary depending on the laptop model
   Option "Protocol" "Auto"
# Next line required only if you want to disable the mousepad while typing:
   Option "SHMConfig" "on"
# The rest of the options are NOT required, just a default similar to
# the Windows drivers with non of the extra features.
   Option "LeftEdge" "1900"
   Option "RightEdge" "5400"
   Option "TopEdge" "1400"
   Option "BottomEdge" "4500"

[edit] Authors

Please feel free to make contributions!

• Flavio Romano (01/2005) - Is the author of the original document. Thanks to beissemj and eallaud for updating the document, adding very useful links and informations.
• eallaud (04/07/05): just a small note to let you know that all suspend modes (to ram and to disk) work great with Ubuntu). One the down side the acpi daemon seems a bit borked but it is just a small annoyance, but the alsa sound driver seems to have some problem also (might be just me being stupid) but oss works anyway. Xorg on Ubunto does not support Xv (might also be just me tho ;-)
• beissemj (6/01/05) - Heavily edited original document. Added several URL's. Updated working hardware. Added modeline information, touchpad configuration, and kernel options. (10/03/05) Added some information re: the framebuffer, updated the URL's, added a kernel config file, and corrected some spelling. (10/16/05) Added keycode information, information re: alsa mixing, more links, and fixed some formatting. (10/22/05) Completely rewrote the Intel wireless section and added how to get the LED to work. (10/02/05) Added some more information re: the Xorg.conf file and the video card. (1/05/06) Adding information regarding LM Sensors and intelfb. As I find out more information about this laptop I will try to keep this Wiki up to date.
• eallaud (11/07/05): the last Ubuntu (Breezy Badger) works even better: all suspend modes work out of the box (to ram or to disk), plus no more problems with ACPI (no need to put noacpi or noapic/nolapic/noioapic for the kernel). Even the remote works out of the box (at least the buttons I used). Also as said above the ipw2200 now works great (as of ipw2200-1.0.8), even the led and rf power button work!
