Mode setting: Difference between revisions

Mode-setting can be done in [[kernel space]] (Kernel Mode-Setting, KMS) or in [[user space]] (User-space Mode Setting, UMS). Doing mode-setting in kernel-space is more flexible and allows displaying of an error in the case of a [[fatal error]] in the [[Kernel (computing)|kernel]], even when using a user-space display server. User-space mode-setting would have needed superuser privileges for direct hardware access, so kernel-based mode-setting increases security because the user-space graphics server does not need superuser privileges.
