To shut off my laptop screen and adjust resolution on my external screen I execute
xrandr --output VGA1 --off
xrandr --output LVDS1 --off
xrandr --output VGA1 --auto
and recently (2-3 weeks) this has made all desktop icons to dissapear from screen.
At one time I thought I had a workaround by
ln -s ~/Skrivbord ~/Desktop
which is my localized name of Desktop, but it only worked the first time.
I find no logs with hints, currently I only know of one way of getting the icons back which is reboot. Adjusting resolution or turning on laptopmonitor has no effect.

Additional info:
It is enough to execute
xrandr --output LVDS1 --off
xrandr --output VGA1 --auto
to reproduce the problem. In my case the latter forces a resolution adjustment that I think has something to do with the problem.
The problem also show when combining the above into selections in lxrandr.
It is also intermittent. On rare occasions it actually work as supposed. I haven't figured out what makes a difference.
