So after using the T400s as my daily driver for the past week I have found that the small screen is a slight limitation. Largely due to the fact that i tend to use it on a desk and have to lean in occasionally to see certain things.
Then I remembered that I had an old 21.5 inch monitor lying around somewhere, and I could find it then i would be able to utilise it in my set up. As part of the setup I modified an old file box that i had lying around by cutting 2 slits into it one on the front and another on the back. The purpose of this was to not only raise the T400s screen to around about the same level as the monitor but to also alow for me to attach a keyboard and mouse with out the being cables all over the place. I then found a USB hub that i placed within the box that the mouse and keyboard connected to. This mean that when the T400s was in the ‘Dock’ only one of the rear USB ports was being used.
When I connected the monitor I was unsure what would happen, as is the case with windows that you can occasionally be greeted by either an extended display or and extension of the primary display. But this wasnt an issue, as soon as the VGA cable was connected the monitor sprung to life and extended the desktop onto the monitor. This was a very pleasant experience as not only was i able to use a full size keyboard and mouse but for some graphical work i needed to do. So after using ubuntu across 2 screens and on more of a desktop based manner, I have the intention of installing Ubuntu to my main desktop PC that is currently running windows 10. This will of course be in the form of a dual-boot as im not yet ready to commit myself fully to ubuntu due to the requirement of specific software that i use not being available on Linux. But unless I need to use them certain application there is a high chance i will be using ubuntu because the dual screen felt smooth and clean.
