I have this same problems for years with the same LCD monitor using different releases of ubuntu and different computers. The monitor is ACER X233H, and it will simply display a grey box showing "cable not connected" when it should be off. Issuing "xset dpms force off" will bring that "cable not connect" right away. Could it be anyway related to bad BIOS' ACPI settings? This is a long going issue. Can we raise this ticket somehow?
