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.

Keep display output when monitor "Disconnected" (sopuli.xyz)

I am using a laptop, with a cheaper monitor that only has one hdmi input. I have two devices that I want to use on this monitor, My laptop and my xbox series, so I got an hdmi switcher.

The xbox handles switching to and from it's input without a hitch, but my laptop can takes up to a minute to recognize the switch and display to the monitor, sometimes not recognizing it at all.

I was thinking that having the laptop continue to output the display whether or not it recognizes the monitor as disconnected would help make switching between them more seamless. Is there a way to achieve this?

I am using KDE and I have the "Do Nothing" option selected under close lid in power options.

I think what you want is an EDID emulator with passthrough or whatever it's called. EDID is how a monitor tells a device what resolution to send and other info. Some cheap HDMI splitters, adapters, audio extractors, etc will let you emulate a specific EDID. One of my audio extractors lets you fake stereo vs surround support to trick the source into sending surround - I think that's also through EDID - since if you're trying to extract surround, it might be because your real TVs EDID is for stereo I assume. So you probably want something like that in before the switch so that the laptop always thinks something is plugged in. Your switch seems to be too smart in actually passing through the real monitor's EDID so the laptop is able to see when it switches.
