Ctrl + Space closing the remote terminal, I use that shortcut as tmux leader key

[thepragmaticmero]

The shortcut Ctrl + Space is a hardcoded keyboard shortcut on the remote terminal https://ip:port/system/terminal, it closes the connection to the remote terminal. My configuration has Ctrl + Space as a leader key for tmux, the hardcoded shortcut inhibits the leader function on tmux. Disconnecting it.

Possible solutions:

• Make the shortcut customizable.
• Change the shortcut to something else.

Is there a cockpit.conf parameter that solves the problem maybe?

Note: I transferred this to the main Cockpit repo, instead of Cockpit Machines, as this appears to be related to the terminal in Cockpit (according to the URL), not the consoles in Cockpit Machines

I see this behavior on both the latest Firefox and Chrome on GNOME 47 on Fedora 41.

It's not an issue for the page itself, as hitting control+space doesn't do anything when the focus isn't on the widget, so I don't think it's intentional from the Cockpit side nor does it seem to be browser-related.

It does disconnect when you're focused on the terminal widget, so I'm thinking that it might be a bug in keyboard handling in the terminal JavaScript from xterm.js (which is what we use for the terminal). The demo at https://xtermjs.org/ doesn't close the session, however, so it might not be that, unless that has a fix our version doesn't have.

ctrl+space oopses cockpit for me and it shouldn't. So we should look into this.

It happened to me on firefox and on the Steam overlay browser (chromium).
