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.

Would downscaling a display allow for better battery life? (feddit.uk)

Hello. I know this isn't completely related to Linux, but I was still curious about it.

I've been looking at Linux laptops and one that caught my eye from Tuxedo had 13 hours of battery life on idle, or 9 hours of browsing the web. The thing is, that device had a 3k display.

My question is, as someone used to 1080p and someone that always tries to maximise the battery life out of a laptop, would downscaling the display be helpful? And if so, is it even worth it, or are the benefits too small to notice?

Your GPU doesn't need to re-render your entire screen every frame. Your compositor will only send regions of the screen that change for rendering, and most application stacks are very efficient with laying out elements to limit the work needed.

At higher resolutions those regions will obviously be larger, but they'll still take up roughly the same % of the screen space.
