Hi,

I'm trying to set up redshift with the randr backend, but this fails with the message "Failed to start adjustment method randr.".

If I run xrandr without any arguments I get this:

Your kernel is too old, and probably your libdrm and mesa too if you run a stable system.

What you are seeing is either vesa or fbdev fallback driver which don't support xrandr 1.2.
