My old laptop’s battery is dying, and I used that as an excuse to buy myself a new on :-)
I had a HP Pavilion zt3240EA, and have been very happy with it. Nice machine. Still, age weights on every one.
I’m gonna be installing Ubuntu 8.04.1 LTS Desktop Edition, 64 bits version, on my new HP Pavilion dv5-1020ep.
Download and Burn a CD
- Go to Ubuntu Download Page and download Ubuntu.
- Check the downloaded file hash. The output must be the same as you see in the Ubuntu Hashes Page.
- Burn a cd (you can use Brasero, for example, if you already use Ubuntu).
Running the live cd
- Boot from the cd.
- After booting it’s important to check the integrity of the cd. Burning cds also fails.
Hardware to check (during the live cd session)
- Graphics (only 1024x768, but check)
- Sound (check)
- Media buttons (check)
- Cable network (check)
- Wireless network (the proprietary Atheros wireless card was found, not tested)
- HP media command (not working)
- Integrated Webcam (check)
Hard Drive Partition Layout
/dev/sda /dev/sda1 ntfs Vista 36002 MB /dev/sda ntfs Vista Recover 8450 MB /dev/sda3 ext3 / 10240 MB /dev/sda5 ext3 /home 10240 MB /dev/sda6 ext3 /storage 94072 MB /dev/sda7 swap 1028 MB
Post-install: Graphics Card
I installed EnvyNG using the Synaptic Package Manager (look for
envyng-gtk) and just had to run it (Applications > System Tools > EnvyNG), after closing Synaptic (important), and choose to “Install the ATI driver (Automatic Hardware Detection)” option.
I now have a normal 1280×800 screen resolution and some desktop effects are already active.
There is an ATI Catalyst Control Center under Applications > Other, where you can tweak things up.
Problems to Solve: if I have Compiz on, there’s a terrible flickering when playing back movies.
Post-install: CPU Frequency Scaling
After installing Ubuntu I noticed that the frequency of both cores was always at 2 GHz (the cpu max frequency in my case).
Because this is a laptop I want the cpu to scale that frequencies as needed.
sudo apt-get install cpufrequtils
You can check this behavior by:
- Adding the “CPU Frequency Scaling Monitor” to your Gnome Panel (add two, one for each core). Frequency should change while you work.
- Check the output of the following (here you can check the driver used - powernow-k8 - and the current scaling policy)
Reference: How to use CPU frequency scaling (cpufreq)
After some time of research here’s a very simple method (read the Reference for much more details):
- Go to your /etc/rc.local file
sudo vi /etc/rc.local
- And add the following
modprobe powernow-k8 sudo cpufreq-selector -g userspace /etc/init.d/powernowd restart exit 0
- Go to your /etc/default/powernowd file
sudo vi /etc/default/powernowd
- Add the -n option
- Check available frequencies for your cpu (if you have more than one core also check cpu1, cpu2, etc.)
- Check current governor
- Check available governors
Problems to solve: restarting powernowd always change the governor to ondemand.
Post-install: Wireless Network card
A warning in the Notification Area showed that a Proprietary Driver is enabled (Atheros wireless card).
Check the driver name:
lspci | grep Atheros
Followed this instructions from Ubuntu Forums, now I can use the wireless card, I found several networks, the signal is good, I connect with my password, but I can’t get an IP… This means no Internet.
Problems to solve: connect to the Internet with sucess.
Post-install: Laptop Optimizations
Here’s some useful tips if you’re running on a laptop:
- Go to your /etc/default/acpi-support file
sudo vi /etc/default/acpi-support
- Change the ENABLE_LAPTOP_MODE option to true
- Install and run
powertop. Follow the instructions on-screen (more info here).
sudo apt-get install powertop sudo powertop
Post-install: Sound Card
Sound works fine, but the Master mute button doen’t mute the Front. This means that the columns still output sound.
To fix this go to System > Preferences > Sound and select the Front device in the list below.
Post-install: File System
Besides the / and /home partitions, only root have permissions to write in every other partitions. In my case /storage.
So, we have to add permissions to our user:
sudo chown -R youruser:youruser /storage sudo chmod -R 755 /storage

Update Manager warned me about 120 available updates. Just letting it go…
