radeontool 命令

常用示例

说明

radeontool is a utility for controlling hardware features on ATI Radeon-based graphics cards, primarily used on laptops. It provides direct access to backlight control, external display output, and low-level register manipulation. The tool communicates directly with the graphics hardware through memory-mapped I/O, allowing control over features not exposed through standard display drivers. Common uses include scripted backlight control for power management and debugging display issues.
