Comment 6 for bug 871986

The autohide option does not work properly on my system. The launcher does not appear when mouse is eiither on the left side nor on the upper left corner.
This happens at all reveal sensitivity settings from the system settings-appearance-behavior menu. All other unity settings is default (i have set a unity --reset script on startup). This happens independently of the window status on the display, even with no active window. The launcher is not revealing unless i press the alt+F1 keybinding.
This happens on a 12.04 X86 installation both as virtualbox Guest in Intel Pentium Dual Core E5200 processor and Intel integrated graphics controller (82G33/G31 [8086:29c2] (rev 10))Host system, and as a test installation on a 8GB USB pendrive on that same system.
I can reproduce that anytime, just by setting launcher to autohide mode.
In both cases (virtualbox and test installation) Unity version is 5.4.0 and all updates are installed.
