My old desktop computer now only works in headless mode - the HDMI ports are dead. But luckily, it still boots normally such that ssh is working - touch wood.
At the moment, I have a W10 virtual guest running under libvirtd, with autostart enabled, network in bridge mode and RDP enabled - so that I can RDP into it and can do some GUI access.
But I want to access my Gnome dekstop of the now headless host - how can I do that with only remote ssh access?
I am running Fedora-35.
There’s a bunch of remote access protocols for CLI and GUI.
Such as SSH/SFTP, VNC, SPICE, RDP, NX, XDMCP, etc.
Cockpit and Nextcloud can provide an alternative approach.
In theory, it’s also possible to utilize X11 forwarding over SSH.
Some of those are documented and supported better than others.
Each of the methods has its own pros, cons and issues.
So, it depends on a specific task which one fits you better.
Adapting own workflow for remote resources is also important.
X2Go is another good one.
VNC viewer is another option. I use it to manage my Pi from my daily driver.
