显示模式设定

显示模式设定(英语:Mode Setting)指的是为显卡设置屏幕分辨率与色深。现今的显示模式设定软件已经可以支持多屏输出和热插拔。

显示模式设定可以在内核空间或用户空间实现。在内核空间实现显示模式设定(英语:Kernel Mode Setting,即KMS)会更加灵活,而且这也可以让内核在出现致命错误时,即使正使用用户空间的显示服务器,也能在屏幕上输出错误信息。

在用户空间实现的显示模式切换(英语:User-space Mode Setting,即UMS)则需要超级用户权限才能直接访问硬件,而在使用基于内核的显示模式切换的情况下,用户空间的显示服务器并不需要超级用户权限,因而基于内核的显示模式切换安全性更佳。
