dpms – VESA BIOS DPMS driver



device dpms


The dpms driver uses the VESA BIOS to manage an external display during suspend and resume. When the machine suspends, the dpms driver turns the external display off. When the machine resumes, it restores the display to its state when the driver was first loaded.




The VESA BIOS DPMS calls do not provide any way to identify a particular display or adapter to manipulate. As a result, this driver may have unexpected results on systems with multiple displays and/or adapters.

Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the other numerous idiot lights which plague the modern driver. Rather, if the driver makes a mistake, a giant “?” lights up in the center of the dashboard. “The experienced driver,” says Thompson, “will usually know what's wrong.”
