I know this is old hat but a solution is not around, at least one that I know of. (Dell XPS) 12 GB Ram. Using the latest edition 2.13
When I reboot, all I get is a blank screen (my wallpaper) and if I don't right click, the fences and their icons do not appear.
This situation was reported more than a year ago, but I don't know if there is a definitive solution.
Please advice.
