To be honest, I have been dragging my feet regarding 19.09 because 19.04 has been going pretty well........finally did the install and everything went together without fault. The install was smooth, fast and straigtforward on my Dell Latitude E6330 SSD.
Very Happy about the consistent transition from the 'login' page after changing the 'wallpaper' choice.....used to be a bit of work to keep the background the same....good stuff.
So far no problems found and the boot up time is surprisingly fast.....never thought I would be saying that about a BSD!
