graphic driver supporting RANDR version 1.3 or VidMode ?

I dont know if you heard about but blue light coming from any source (TV, monitor, LED) is preventing you from sleeping.

in the linux they have xflux and redshift to change the temperature of the color of the monitor at night to protect you.
redshift is open source but needs the "Your graphics driver and X server needs to either support at least RANDR version 1.3 or the VidMode extension."

I am not sure whether the xserver is a must, thats is why I ask about the other extension.

so do we have it or not ?

thx

Yes Lio,
should be cool to have it to sleep quickly and to not have red eyes after long coding evenings ;)
