What do you mean by "terminal freezes"?

[JustRed23]

If you meant that your ssh connection freezes, then this is normal behaviour, as this also happens on forge due to the use of JLine

[Shelly333-2]

in my case any terminal freezes not just ssh

[Shelly333-2]

that didnt happen on forge might be just a random bug

Just out of curiosity: Do you have something like this in your logs?

[ERROR] Failed to construct terminal; falling back to unsupported
java.lang.NumberFormatException: For input string: "0x100"

For me, with kettinglauncher 1.5.0, my terminal simply doesn't show typed characters, after I stop the server. Until then everything behaves correctly. I can make the terminal behave correctly again when executing reset.

Ctrl+L, Enter, reset, Enter is a known combination to get most terminals operational again. Ctrl+L, Enter simply clears any junk that might be currently in the commandline and is thus not needed in this case.

my terminal works fine on version select and when starting the server however.
I tested with Konsole on Plasma 6, NixOs 24.05.

Edit: it seems to not be consistent in breaking like this?

[C0D3-M4513R]

I found that this is pretty consistently reproducible (or at least what I described), if you stop the server via typing stop (and not with ctrl+c).
Also I found that c217780 (should be 1.2.0 or so?) also also has the issue (that is the earliest commit that will work at all. earlier commits all refuse to start, because of some issues).

So I think this might not even be a launcher issue (as I wouldn't even know what would cause input to stop being displayed), but just the fact that an unsupported terminal causes issues?

this error didnt happen [ERROR] Failed to construct terminal; falling back to unsupported
java.lang.NumberFormatException: For input string: "0x100" and i probaly expained the reproduction process starting ketting causes the terminal to freeze and on ssh only stoping causes the freeze

[C0D3-M4513R]

I can’t reproduce the freeze then (Only the behavior I described, which is not a freeze).
I am however only testing via a local Terminal Emulator, not an acutal tty.
I’ve also not tried via ssh, but I also don’t have a suitable pc for that rn.
