So I have a laptop, an older box, and one monitor. The former has some work stuff which is sensitive, I want to use the other one for anything web browsing etc. Both run linux (manjaro the first, pop-os/ubuntu20.04 the second).
I could switch display port (HDMI vs VGA) back and forth, but that is rather unpractical. Also, requires two mouses, two keyboards on my desk. So I thought I want to access the older box from the main one via some remote desktop.
I first tried vnc, but first it appears horribly laggish, but even more it requires me to boot directly into the user on the other machine, as I was not able to set it up as to be presented with the login screen first.
Are there other options? 20 years ago I remember using Xserver directly onto the remote box, but I am not sure if there are better options today?
