## 4. Frame Buffer Resolution Maintenance

Frame buffer resolutions are maintained using the utility fbset. It allows to change the video mode properties of the current or a user defined resolution. It's main usage is to tune video modes and to store custom resolutions into one of the `/dev/fb?user?` entries, e.g. during boot up in one of your `/etc/rc.*` or `/etc/init.d/*` files, after which those resolutions can be used by applications.

Fbset uses a video mode database stored in a configuration file, so you can easily add your own modes and refer to them with a simple identifier. The fbset install script also creates the special device nodes for the device dependent predefined resolutions.
