I have been messing around with xorg.conf on my laptops, in order to get the TearFree option working with the intel driver. On one machine it works great, but I have not figured out the second one yet.
By default Xorg uses the modesetting driver, but if I specify intel in xorg.conf, it works, seems more responsive, and looks a lot better.
The only problem is that brightness (via xbacklight) does not work when I have it configured this way.
In man intel there is this:
Code:
Option "Backlight" "string"
Override the probed backlight control interface. Sometimes the automatically selected
backlight interface may not correspond to the correct, or simply most useful, interface
available on the system. This allows you to override that choice by specifying the entry
under /sys/class/backlight to use.
Default: Automatic selection.
... but the reference "/sys/class/backlight" is a Linux reference I think? I searched around and found that in Linux there is a file in the above path that gives you direct access to your brightness setting.
Does anyone know if OpenBSD has a file that gives you access to the backlight like described above?
