How to make additional monitors over the network?

Question

linux

There is a laptop on which Arch is installed and a stationary computer with Windows and two monitors, but it will not be difficult to install a second Arch system on it. Sometimes when working on a laptop, there is a shortage of workspace, you have to switch between windows to peek or something else. So I would like to use two monitors that are connected to a stationary computer to display, for example, debug information and interact with it, that is, high fps is not required. The laptop has only one HDMI connector and VGA monitors, it would be possible to mix something up with adapters, but it’s constantly disconnecting to connect them back to the stationary one is so-so. Therefore, the solution turns out to be connected to the network. Actually, I think you should probably create somehow two virtual monitors on a laptop with an indication of the resolution, since the monitors have different resolutions, and on a stationary station to accept somehow a stream of these two monitors. How to do it all?

Answer 1

Everything turned out to be simple)

xrandr --addmode VIRTUAL1 1920x1080
xrandr --output VIRTUAL1 --mode 1920x1080
x11vnc -rfbport 25901 -clip 1920x1080+1920+0 -forever

And then we put the VNC client on the second machine and connect.
By analogy with the commands above, you can add another display.

Answer 2

No way. The most not problematic option is a KVM switch, but they cost decently.
More hemorrhagic is collective farming from a set of pieces of iron. Well, for example, buy 2 of the simplest dvi or vga kvm switches (500 rubles for each can be found). Since there is only hdmi on the laptop and it is the only one, you can buy 2 usb video cards (you can find one piece apiece). For convenience, you can also buy a usb hub for a laptop where to plug in vidyashki. Then you put all this collective farm together and at the output you will have 2 monitors that are switched by buttons on the remote control.
In the case of purely only 2 Linuxes and on a computer with monitors and on a laptop, then you can share them, but there will be an extraordinary amount of pitfalls with crutches and the result of the work is very unlikely to satisfy.

Answer 3

Perhaps it will be easier for you to fumble the keyboard and mouse between them (for example, to control the stationary from the laptop), look towards the Synergy program and its capabilities.
