Revision history [back]

It appears that the "adjust automatically" setting is not doing anything on my device. I have defined brightness on the display page to "max" with "adjust automatically" ticked on, but the display is not reacting to darkness or light in any way. Brightness of the display is constant, no matter if I'm in a dark room, or well luminated heaven.

There is probably a file somewhere in /sys which I could cat to see if the light sensor is actually working, but so far, I haven't been able to find it.

Edit: As said in the comments, the sensor seems to be working just fine, but the auto-brightness adjustment implementation just isn't aggressive enough to cause any real difference in brightness levels when switching between well lit room, sun light or eternal darkness (finland).
