From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

GNOME 45's Mutter Implements A Dedicated KMS Thread (www.phoronix.com)

submitted 1 year ago by [email protected] to c/[email protected]

Red Hat's Jonas Ådahl began working on this Mutter KMS kernel thread implementation a half-year ago and finally it recently was merged for the GNOME 45 release due out in September. By having this dedicated thread there should be lower latency cursor movements and possible avoidance of cursor stutter. It should be a latency win although various bugs have been reported since this code was merged in late July. But given the timing and still more than one month until GNOME 45.0 ships, everything should be in good shape for the stable debut.

Not an expert, but I feel like this might really improve the perceived responsiveness of the system under load.

I thought KMS meant something else

Is it supposed to be kernel mode setting?

Coincidentally I also merged a kms thread into KWin late July. When dragging windows around, the cursor is now visibly ahead of the window.
