My screen shows what appears to be a desert scene when it boots

On occasion, the computer gets confused when it first boots up in a new area, so it’ll show the default Linux desktop screen instead of the Waiter ECC screen. This seems to happen if the unit has been powered down for any length of time or if its in a new WiFi environment where its scanning for WiFi networks and sees different networks.

Simply turn the power off for about 5 seconds then turn the power back on to force it to reboot again. This normally resolves the problem.
