说明
con2fbmap shows or sets the mapping between Linux virtual consoles and framebuffer devices. Framebuffer devices provide a unified interface for accessing graphics displays and are accessed through device nodes /dev/fb\<n\>, where n is the device number. When called with only a console number, it displays the current framebuffer mapping for that console. When called with both a console number and a framebuffer number, it reassigns the console to use the specified framebuffer device. This is useful on systems with multiple graphics adapters or displays, allowing different virtual consoles to render on different screens.
参数
- console
- The virtual console number to query or modify (required).
- framebuffer
- The framebuffer device number to map the console to. If omitted, the current mapping is displayed.
