I just finished installing Ubuntu Intrepid Ibex on my HP Pavilion dv6810us, which is part of the HP dv6000 series
Installation was fairly straightforward, the only hiccup I found was that wireless networking was not working out of the box, I had to install ndiswrapper, but thankfully this was pretty painless. All I had to do was install ndisgtk
sudo apt-get install ndisgtk
And the Windows XP drivers for its wireless card (identified as 03:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01) by lspci
According to this post in the Ubuntu forums, the correct drivers can be found here.
Once I installed ndisgtk and downloaded the windows drivers, all I had to do was point ndisgtk to the .inf file included with the driver, and wireless "just worked", no mucking around with blacklisting drivers or anything like I had to do with previous versions of Ubuntu
I also ran into an issue in which the system would stop booting unless a key (any key) was pressed repeatedly. This issue seems to be affecting several Hewlett Packard (HP) and Compaq laptops.
This issue was reported on launchpad, and I found a workaround there.
The file /boot/grub/menu.lst needs to be edited as root, I use vi as my editor, substitute the following command with your favorite editor:
vi /boot/grub/menu.list
Find the following line:
kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=c877e76e-7e7f-4b47-aec7-6ae28d1ab767 ro quiet splash
and append "acpi=noirq" to it. After doing this the line should look like this:
kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=c877e76e-7e7f-4b47-aec7-6ae28d1ab767 ro quiet splash acpi=noirq
After making the above modifications I was able to boot to Ubuntu Intrepid Ibex normally.
