Ubuntu 10.04 on an HP Pavilion dv4i notebook

I wanted to use Ubuntu on my HP Pavilion dv4i-2100 notebook. Since the installation was not all the straight forward I would’ve like, I’ll write here all the steps I had to go through to install Ubuntu on my laptop.

First of all, Ubuntu 9.10 amd64 does not install on this laptop, so I installed Ubuntu 10.04 beta 1. The CD image was downloaded on March 26, 2010. The stable 10.04 release is expected for April 29, 2010.

During the installation process, after choosing all the options and partitions, you will see a summary of your options before starting the installation. Click the “Advanced” button and select grub to be installed in the root partition of your installation (e.g. “/dev/sda1”) instead of the default value “/dev/sda”. With the default value, grub packages are not installed (i.e. “/boot/grub” would be empty). This is pretty weird, and I hope it will be solved in the final 10.04 release.

After the installation, grub was not working yet. I had to boot from the ubuntu CD and make a “grub-install”:

sudo -i
mkdir /mnt/root
mount -o bind /dev /mnt/root/dev
mount -t proc none /mnt/root/proc
mount -t sysfs none /mnt/root/sys
chroot /mnt/root
grub-install /dev/sda

At this point I was able to see the grub menu when turning the notebook on.

Ubuntu was not booting correctly in graphical mode. It just hanged and I had to power-off the notebook with the power button (Ctrl-Alt-Del did not work either). I had to boot in recovery mode (second item of the grub menu), choose the “resume” option of the recovery mode menu, login with the user I created during installation and start the graphical mode with the command “startx”.

The problem was that the Modem Manager was giving some problems, probably because my notebook does not have a modem. I disabled it with the command:

sudo apt-get purge modemmanager

This solved the boot problem and I was able to boot Ubuntu normally.

The wired network worked perfectly, but the wireless did not. I had to install the wireless driver connecting the wired network and going to “System > Administration > Hardware Drivers”. There you will see the wireless driver, which must be activated.

That’s all folks. Enjoy!
