When clicking first time enter, screen freeze until I change size of terminal

Later no clicks are recognized except ctrl + q

I see the same behavior with gnome-terminal, mate-terminal, xterm and xfce4-terminal. It does work with Cool Retroterm.

Even after maximizing kbt to get it to display the keys it's not actually working, in that key presses don't appear.

My OS is PopOS 22.04 (based on Jammy) running GNOME desktop 42.5 and Xorg. Mesa is at 22.3.5, Vulkan is at 1.3.204.

I'm running Xorg and not Wayland.

I installed using cargo install kbt. My rustc is at 1.70.0.

I’m pretty sure it’s because you are running xwayland. We have a ticket to to explore if it’s possible to capture real (non terminal) keystrokes in wayland -> #3

Ok, @johnblommers, ivalidated my previous claim. Will look into this as a bug then!

Sharing some findings.

These terminals, while in focus and keyboard is being clicked, do not produce X11 KeyPress and KeyReleased events which we use to detect key presses.

I found that xterm behaves non-deterministically. If moved around in window manager, sometimes starts emitting needed events. I suspect that it grabs input focus somehow, not sure yet.

The 1.1.0 release tried to address this, for me it worked with all those terminals listed by you. Let me know if you have any additional issues.

Excellent kbt works with all of the terminals listed above: gnome-terminal, mate-terminal, xterm and xfce4-terminal. It still works with Cool Retroterm.

And ... it also works with Wezterm which is written in Rust :-)

kbt does want an X-Display to work. Therefore you cannot run it from a TTY session, for example CtrlAltF4.
