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.

How to set resolution to a portion of a screen or just screen share part of one? (lemmy.ca)

I've got one of those crazy-wide screens that I usually use at 5120x1440 and it's great. However, since I work remote, I often want to share my screen with someone on a typical 16:9 screen and the options of "tab", "window" or "entire screen" aren't particularly useful.

I'd like to be able share either (a) a portion of the screen (half?) or (b) change my resolution temporarily to something like 2650x1440 and just share the whole screen.

The problem is that as far as I can tell, (a) isn't an option, and while I can (b) change my resolution to something 16:9, it renders wide across the screen turning effectively every pixel is a wide rectangle. It's... hard to look at.

I'm using Arch with GNOME+Wayland. Is there some way for me to do either of the above?

How exactly does that work?

On Sway:

This goes in Sway's config...

output HEADLESS-1 {
	pos 5120,0
	mode 1920x1080@20Hz
	bg ~/tausta_kuva fill
}

And this alias starts wayvnc.

alias RuutuVNC='swaymsg create_output && nohup wayvnc 0.0.0.0 5900 >/dev/null &'

After that, connect the VNC client on the tablet to port 5900 on the machine and sail the mouse cursor over to it when selecting the screen to share.

There must have been a config for wayvnc somewhere, but I can't find it. I don't need to use this anymore after switching from a dual portrait setup to a dual LG DualUp setup, so that my screens are now pretty much square and the right way around. On the dual portrait setup, my screenshare would show up sideways in landscape :D
