I\'m on Arch Linux, using pcmanfm from Git.
I have two 1280x1024 screens, the left one in landscape orientation and the right one in portrait orientation, achieved like this (script produced by arandr):
xrandr --output VGA-1 --mode 1280x1024 --pos 1280x0 --rotate right --output DVI-I-1 --mode 1280x1024 --pos 0x256 --rotate normal --output HDMI-1 --off
The outlines of my screens are sketched in red on this screenshot, and you can see my wallpaper settings in it too:
When I start pcmanfm, most of the icons on the left hand side are covered by the desktop wallpaper, so you can't see them in the screenshot. Even the two that you can see in the rectangle at the top left of the screenshot are actually off the top of the screen, so I can't see them except in a screenshot ;)
If I then click in the blue rectangle I\'ve sketched, the icons become visible (apart from the ones off the top of the screen of course), as you can see in this second screenshot:
If I then click in the yellow rectangle I\'ve sketched, the icons become invisible again.
Look at the desktop wallpaper in the two screenshots, as well. I think that shows you what\'s going on. PCmanfm is drawing two root windows or whatever they\'re called, and it isn\'t calculating their size/position correctly, so they are overlapping.
- I can\'t drag a desktop icon outside of the top left 1280x1024 area - i.e. below the top of the yellow rectangle, or to the right of the blue rectangle.
- If I right-click anywhere in the right-hand screen, or in the little square at the bottom right of the left hand screen (i.e. to the right of the yellow rectangle and below the blue rectangle), then I don\'t get the pcmanfm right-click menu.
