Maybe the same issue as https://sourceforge.net/p/lxde/bugs/895/ . If this issue is still reproducible, would you write the result of "$ xrandr" ?

I've got the same issue running Arch Linux 64bit on VMWare Fusion with lxrandr-0.3.1-2.

Well, actually if xrandr output is as this, lxrandr should segfault: The problem is preferred 60.00*+ line - current lxrandr source fails to parse this correctly (by regex), however while I want to reproduce this, I don't know how xrandr actually return preferred string....

Probably missing X server display driver - check this url for solution:
