These instructions relate to the simple mode. They probably aren't needed with the full KDE mode.
To have your Eee PC automatically check for software updates, first follow these instructions to set up a script to run when the network connection comes up. Then, add these lines to the newly-created ~/.network-autostart file:
# Update apt-get sudo apt-get -q update # Run apt-get but do not try to install anything sudo apt-get -dqy --force-yes upgrade | grep "The following packages will be upgraded" > /tmp/apt-get.tmp # If the file /tmp/apt-get.tmp exists and is not 0 bytes in size, then updates are available. Run zenity to display an icon if [ -s /tmp/apt-get.tmp ] then zenity --notification --text="Upgrades available" & fi
If updates are available, zenity will display an icon in the system tray. Hovering the mouse over the icon will display the text “Upgrades available”. Clicking on the icon will remove it. You will have to run Synaptic or apt-get manually to install the updates.
