backlight INSTALL ================= Supported systems ----------------- - Linux: requires video ACPI module, - FreeBSD: requires the `acpi_video(4)` loaded, - OpenBSD. Installation on Linux --------------------- First, build the program: make On Linux, adjusting the brightness can be done as normal user if you have write access to the appropriate files which are usually under */sys*. The recommandation is to install the udev rule which change the ownership of the brightness file to `video` group and writable by users in this group. Use the `install-udev` for that purpose. Then don't forget to check if you are part of the video group. make install make install-udev Otherwise, as alternative you can simply install the binary as setuid if you don't run udev. make install-setuid Installation on FreeBSD ----------------------- In FreeBSD, it's required to have the tool in setuid as there is no way to change sysctl values from a regular user. Also, you will need the ACPI video module, add the following to your */boot/loader.conf*: acpi_video_load=YES Alternatively, you can compile this module into the kernel. Then install using: make make install-setuid
