I am really desperate to resolve this problem. I installed xbacklight, closed my laptop, reopened the laptop, saw the disk activity that indicated the system had resumed from suspend. I entered Ctrl-Alt-T blindly, entered "xbacklight -set 100". Nothing happened. Entered "vbetool dpms on". Nothing happened. I previously tried both commands while the system was running normally and saw nothing to indicate that they didn't work. However both tools are dependent upon the driver working to implement the standard interfaces that the tools use. All I want is a command that I can issue to turn on the bloody light bulb! If I had such a command I could add it to the script that runs when the lid is opened and I could get off everybody's back.
