Description Philip Lykke Carlsen 2010-09-02 09:45:40 UTC

Version:           unspecified (using KDE 4.5.0) 
OS:                Linux

It would be really cool and usefull if KDE could change its colour contrasts according to the level of ambient light, such as to be easier on the eyes.

by writing KDE's colour contrasts I specifically mean
* The colour of kwin's decorations
* The current plasma theme
* The QT colour theme
* The icon theme

Also, if the hardware dosn't have any useful sensors for detecting light conditions one could just calculate an estimate based on the user's location and the time of day and year.

I realise that this would probably be a gigantic task to undertake, but it would be really usefull, if not to say directly sexy.

Reproducible: Didn't try

As you already mentioned, it involves many components, but I think first we have to make sure we actually have a way to get the light information into KDE at all.

Since this is highly platform specific, I guess there should be support in the hardware detection library "Solid", at least API wise, then later the actual implementations can be done.

Reassigning to solid to check if we have such API first.

Sounds potentially tied to powermanagement (which sometimes lean toward context/environment awareness).

Reassigning to specialists. ;-)

I'm marking this bug as upstream. I'd like to see ambient sensors support in UPower or somewhere else to implement that. If this is already present, poke me with the documentation and reopen this bug!
