EDIT Oct 13 2008: Fix for wireless problem (sometimes difficult to connect to Access Point)

EDIT Feb 10 2010: This HowTo is no longer needed on Ubuntu 9.10. Everything OK out of the box.

HP gave us hplip linux drivers for their printers, so when I needed to buy new computer stuff I bought HP (laptop and color laser network printer). Everything (screen resolution, graphics hardware acceleration, wifi, etc) works out of the box. No surprise really, as all these components are Intel with known open source drivers.

Anyway, there is one little thing you need to do make of this laptop a dream GNU/Linux laptop.This bug (the laptop sometimes crashes when the lid is closed) affects this laptop, but there is an easy workaround:

$ sudo chmod +x /etc/rc.local

$ sudo vi /etc/rc.local

(change “vi” into “nano” if you don’t know vi…)
Before the “exit 0″, add this line

/bin/bash -c “/bin/echo 1 > /proc/acpi/video/*/DOS”

$ sudo /etc/init.d/rc.local start

Every time you boot your laptop, this setting will be enabling so you can safely bring the laptop into sleep. Maybe, it would be a good idea to bookmark the page of the Ubuntu LaptopTestingTeam/HP6710b.

A problem I discovered late (because of its randomness) is that the intel wifi-card (Intel Corporation PRO/Wireless 3945ABG) has sometimes trouble to connect to a Access Point. Once the connection is made, tough, the connection is fast and stable.

I tried different things (new kernel modules, disable network scanning on the driver, etc), but the problem seemed to be tied with Network Manager rather than with the card itself. I installed Wicd as a replacement and everything seems to be fine:

$ sudo vi /etc/apt/sources.list
Add this at the end:
deb http://apt.wicd.net hardy extras

$ wget -q http://apt.wicd.net/wicd.gpg -O- | sudo apt-key add -

$ sudo apt-get install wicd
(This command will remove Network Manager, if you need to reinstall it: sudo apt-get install network-manager-gnome)

Reboot and configure you networks from within wicd notification area icon.

A better solution is here https://bugs.launchpad.net/ubuntu/+source/acpid/+bug/157691/comments/33

There is a package called hotkey-setup which incorrectly reads xorg.conf under Ubuntu 8.04.

This is an unofficial update but immediately fixed the issue on my 6710b.
