lol, I've never seen people putting widescreen on their side (I didn't even know it was possible
XD)...
but yeah I guess to make a desktop for that, make a wall with the height of the widescreen (on its side) and width of
the normal screen width + widescreen width. Then put all the main stuff near the top. Don't leave the bottom
totally blank, just have it be a pattern or gradient or something simple that you wouldn't mind cutting off on the
non-wide screen. Then to set the wallpaper, have it as "tile", the same way you would set a dual-screen
monitor
