I am new to windows 7, I used windows XP, but changed to linux just before windows 7 was released. I use a medion MD97888 laptop, with an intel chipset (and it was bought with an OEM version of windows 7). Now I want to use windows to view some DRMed silverlight videos from my university. Due to my often nightly studying, sleep requirements and preference for a dimmed screen I am looking for a way to dim my laptops backlight from windows. In linux I use 'echo x > /sys/class/backlight/intel_backlight/brightness' to dim my backlight at night to the lowest possible level without turning it off (50 in my case). So I searched in duckduckgo and ixquick hoping to find something similar. I found several programs to dim the screen, but the only thing those programs actually seemed to do is to reduce the video brightness (without dimming the backlight), and most do not even dim tooltips and shellmenus. There is a list of programs at http://www.makeuseof...efault-minimum/ the desktop lighter is the only one dimming tooltips (but it does not seem to dim the backlight, at least not to the extend that I am looking for). Does anybody have a solution? Is there a setting in windows that is similar to the one I use in linux? EDIT: I just realised I forgot to mention something: I tried using the hotkeys and the powersettings, but the lowest end of the slidebar is too high for my preference (I had the same problem in linux mint but solved that using the method described above).
