Ubuntu encrypted swap

It is easy to enable home folder encryption on Ubuntu, it is an option during installation, but for swap it is not clear how to do this. Looking for instructions online results in lots of different ways to do it. However, just running sudo ecryptfs-setup-swap should do it.

Virtual resolution on Linux

Suppose you have a netbook with a small screen (say: 1024×600 resolution) and you want to use some applications that expect higher resolutions.

On Ubuntu for example you can open the terminal (Applications -> Accessories -> Terminal) and enter the following:

$ xrandr --output LVDS1 --panning 1024x768

LVDS1 seems to work for my netbook and is used as an indication for the internal panel in the netbook. Use xrandr without options to see all possible display outputs. To restore the display, change the panning option to 1024×600 again.
