Comment 10 for bug 382056

I have experienced this since 12.04 and it persists in 14.04. Lenovo X1 Carbon (interal Intel graphics) connecting to an external display through mini dp.

It appears to arise through a change in the number of displays connected before a suspend and after a resume. For example, the following sequence: 1) the laptop is put into suspend with no display connected 2) an external display is connected whilst still in suspend 3) the laptop is then resumed.
> + Windows moved to wrong workspace after suspend/resume
To further confound the issue, windows might be outside the viewable area and need to be moved back into view used Alt-F7 shortcut as no title bar is visible.
