Ubuntu and especially the former netbook-remix (now ubuntu-netbook) are really great for a small and not so powerful machines with rather small screens like the eeePCs, Besides almost everything running smoothly out of the box (even compiz), there are very few glitches, that maybe not very importand in everyday usage, but should be fixed to make the most out of your eeePC. In this howto you'll learn how to fix wireless, sound and harddrive issues.
1. When connecting a headphone the internal speakers don't switch off.
a) edit the alsa-configuration file by e.g. start editing it as root with gedit using the following command in a shell:
sudo gedit /etc/modprobe.d/alsabase-conf
add the following line to the very end of the file
options snd-hda-intel model=auto
b) if this doesn't fix it completely install the backport alsa drivers with the following command:
sudo apt-get install linux-backports-modules-alsa-karmic-generic
2. The internal microphone doesn't work, a connected external though does.
This fix is pretty weird, but it works:
a) You have to install a volume control application, that can control the left and right channel of the internal microphone separately by typing the folloiwing in a shell:
sudo apt-get install pavucontrol
Now startup this program by selecting it from your gnome/ubuntu menu in Sound&Video / Pulse Audio Volume Control or start it by typing in a shell:
When started select "input devices", click on the lock-symbol to unlock the left and right chennel and set the left channel to 100% (or less if you want) and the right channel to 0% (this has to be 0).
3. The WiFi connection has a weak signal or has intermittend break-ups.
When you made sure it doesn't have something to do with your wireless router or the overlapping of the signals of multiple WiFi networks in your neighborhood or house the following will help.
Install the backport wireless drivers by typing the following command in a shell:
sudo apt-get install linux-backports-modules-wireless-lucid-generic
If you tried this and you still have wifi issues, try to change the channel on which your wireless router works. This usually can easily be done in the settings of your router. Be aware of that wifi problems don't follow a straight logic meaning that you can have three notebooks in one room and the one closest to the wireless router has the weakest signal. I guess if you really want to find the logic you can only start measuring where a wifi signal from another router on a specific channel is present, draw a card and find out about overlappings ;)
4.The harddrive very often creates a strange clicking.
It seems that this is caused by something weird in the power saving functionality. I don't know for sure but I guess what you always can hear are actually the read/write heads of the harddisk moving to the park position. If this is true, the sound is not only annoying but seriously puts stress on your harddisk and might even decrease its lifetime. To change this edit the harddisk configuration file /etc/hdparm.conf as root:
sudo gedit /etc/hdparm.conf
add the following line to the end of the file:
apm = 254
apm_battery = 254
To make all these changes work reboot your machine. All this information here is taken from
there you'll also find fixes for almost every portable device. The fixes described on this page are tested on an eeePC 1005 HA running Ubuntu 9.10.
