It is still possible to set the Pi to boot to the command line for people who prefer that – just toggle the relevant setting in the Raspberry Pi Configuration application described below. This was a decision taken because this is the expected behaviour for all modern computers the default interface for a personal computer in 2015 is a desktop GUI, not just text on a screen. The first thing anyone starting the new Jessie image from scratch will notice is that the default behaviour is to boot straight to the desktop GUI, not to the Linux command line. And at the same time as the upgrade to Jessie, we’ve added a bunch of changes and improvements to the desktop user interface. There are modifications to the underlying system to improve performance and flexibility, particularly as regards the control of system processes, and as with any update, there are numerous bug fixes and tweaks. Many of the changes between Wheezy and Jessie are invisible to the end-user. Recent versions of Raspbian have been based on Debian Wheezy (the penguin who’s lost his squeaker in “Toy Story 2”), but Raspbian has now been updated to the new stable version of Debian, which is called Jessie. The Raspbian operating system is based on Debian Linux, and the different versions of Debian are named after characters from the “Toy Story” films. Yes, it is that Jessie, but not in that context. Jessie is here? Who’s Jessie? Wasn’t she the cowgirl doll in “Toy Story 2” – you know, the one who got abandoned in a park to that Sarah McLachlan song, resulting in at least one software engineer finding he had something in his eye at that point…?
