I have two users on my PC, one desktop environment looks similar to a standard eOS except the icons are MATE-like and some icons are missing.
I have tried updating and re-installing the desktop with no luck.
All help appreciated.
Maybe unrelated info: I am running Windows 10 and elementary OS dual-boot to try escape the windows jail, I have managed not to boot into windows for over three months and am very happy with eOS and have installed it on my kids PC's as their default OS. Runs very well and all the hardware/dongles etc work just fine.
