Table 2-3. Common xorg.conf section names
| Name | Description |
|---|---|
| Monitor | Monitor specifications. |
| InputDevice | Keyboard configuration. |
| Pointer device configuration (mice, graphics tablets, touch screens). | |
| Device | Video card configuration. |
| Screen | Associates a Device with a Monitor and defines the available resolutions and color depth. |
| ServerLayout | Associates one or more Screen sections with two or more InputDevice sections. Different ServerLayouts can be defined to combine devices in different ways for use at different times; for example, a laptop can have a ServerLayout that specifies that the internal+external displays should be used, and another one that specifies only the internal display. |
| Files | Location of auxiliary files such as fonts, drivers, and color tables. |
| ServerFlags | Flags to control the overall operation of the X server. The flags may alternatively be placed in the ServerLayout sections if they apply to some ServerLayouts but not to others. |
| Extensions | Enables/disables extensions to the server capabilities. |
| Module | Loads additional modules. (Modules may provide extensions, but extensions don't have to exist as separate modules.) |
| Modes | Defines special video modes (rarely required). |
| DRI | Direct Render Interface (DRI) device configuration, used for some 3-D gaming. |
