I found that I use my laptop’s touch screen more frequently – it is particularly useful for image editing. However, when I work in my (home) office I also use a multi-screen set-up with three monitors. The problem is that the touch region of the laptop screen automatically gets scaled to the overall size of my screen, which spans multiple monitors.

My desktop computer has a wired connection to the internet and so the built-in wifi card is normally not used. I decided to enable and use it as a wireless access point.

Don’t ask why… A rooted Android phone or tablet can be configured to connect to an ad-hoc network, and if a separate program can configure a Linux box to act as an access point, NetworkManager should be able to do the same. As far as I can see, there are no good technical reasons for either of these deficiencies.
