My mother wanted a simple laptop, which is sufficient for browsing the web, writing some emails and some letters. So I haven chosen a HP Compaq 615 since it has a very low price but does it's job. As I don't want to bother my mother with viruses and I wanted the flexibility to setup a system that just fits her needs, I installed Kubuntu. Therefore the next advantage of the HP Compaq 615 is that it has no Microsoft Tax - it's delivered with DR-DOS only.
Ubuntu is supported very well on this laptop. After some tweaks, I managed to get everything working but some function keys that are not really required.

Graphics
Right after installation the system was running with the OpenSource radeon driver. While this is OK for 2D operations, it does not allow all these nice desktop effects, for which you need to enable the compositing extension of the X11 server. Ubuntu Jaunty also provides the commercial driver in its repository, but this driver did not work for me. The X server was not able to startup properly and showed random artifacts.
So I tried the latest driver provided by ATI and that one worked instantly.
- Download the latest driver for the ATI Radeon HD3200 graphics adapter from AMD (I have downloaded version 8.650).
- Create the driver installation package:
sh ati-driver-installer-9-9-x86.x86_64.run --buildpkg Ubuntu/Jaunty
- Install the driver packages:
sudo dpkg -i *.deb
- Create an intial X11 configuration:
aticonfig --initial
- Reboot the system.
After these steps KDE was able to run with compositing enabled and all the nice effects run smoothley.
Sound
Getting sound running was the trickiest part. After quite some googling and trying out different alternatives, I finally found the answer on launchpad. However it does not work with the driver version that is mentioned there. You will have to use the newer driver, which is mentioned some postings below that answer. Here are the steps I followed to get a running sound system:
- Before you continue, I recommend to run a full system update to make sure that you have the latest kernel version already installed. In case there is a new kernel available, reboot your system before continuing.
- Run uname -p and note the machine type. It will either return i686 or amd64.
- Run uname -r and note the kernel version.
- Download the latest Alsa driver for the sound system from linuxant.com:
- Choose the appropriate platform for your machine type: i686, amd64
- Download the package that matches the kernel version.
- Unzip the package and the install the contained deb package:
sudo dpkg -i alsa-driver-linuxant_*.deb
- Edit the file /etc/modprobe.d/alsa-base as root user and add the line
options snd-hda-intel model=laptop
to the end of this file
- Then edit the file /etc/modprobe.d/options as root user and add the same line
options snd-hda-intel model=laptop
to the end of this file.
- Reboot
Most probably you won't hear any sound unless you are using headphones. To enable the internal speaker you have to run kmix and adjust the volume of the speaker channel.
Summary
The laptop does its job. You shouldn't expect too much from it (well, I am working with an HP EliteBook 8530w and it's really unfair to compare the both with each other), but given its very low price I was pleasantly surprised. The only thing that's really disturbing in my opinion is the glaring display, but well - it's the current hype and if the room's lighting fits the display is OK.
