Mode setting is a software operation that activates a display mode (screen resolution, color depth, and refresh rate) for a computer's display controller. In kernel mode-setting (KMS), the display mode is set by the kernel. In ''user-space mode-setting'' (UMS), the display mode is set by a userland process. Kernel mode-setting is more flexible and allows displaying of an error in the case of a fatal error in the kernel, even when using a user-space display server. User-space mode setting would require superuser privileges for direct hardware access, so kernel-based mode setting removes the need for superuser privileges for the user-space graphics server. == Atomic mode setting == Atomic mode setting means setting the output modes of a single graphics device. Collecting the video mode, encoder and connector setup over the whole graphics card into a single operation avoids flicker. Either the whole set succeeds, or it fails. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mode setting」の詳細全文を読む スポンサード リンク
