Thanks for all the help Christopher, but I think that I will just upgrade to Vivid as soon as I can, as it is only a few weeks away, so no backport needed and it can be closed as invalid.

Status in xorg package in Ubuntu: Incomplete Bug description: This has been going on for a while, but only seems to occur on dual monitors and when certain applications are opened. Previously the screen would go black and then reappear and be fine. Now the screen either goes black and does not come back until one of the monitors is removed or it flashes on and off like it is trying and re-trying to set the resolution but failing. This goes on until I unplug a monitor. Applications that cause this behaviour range from Viber Desktop to Wine programs through to System Settings and Totem Video Player (in this example in the bug) but it can be random, sometimes but not always do they cause this behaviour. Just to clarify, this does not happen with the laptop screen, only when external dual monitors are used.
