What's Wrong?

Title: Keyboard input not echoed to console in Claude Code

Description:

Keyboard input is not being echoed back to the console window when using Claude Code. The application appears to be receiving the input (commands execute), but typed characters are not visible.

Environment:

• OS: Linux 5.4.0-26-generic
• Terminal: xterm, XFCE
• Claude Code version: 2.1.1

Steps to Reproduce:

1. Start Claude Code in a terminal
2. Type any text
3. Text is not displayed/echoed back to the console

Expected Behavior:
Keyboard input should be visible as it's typed

Actual Behavior:
Input is not echoed to the console, making it impossible to see what you're typing

Additional Information:

• This issue started recently (previously worked fine)
• Normal terminal sessions outside Claude Code work correctly
• Issue persists across new terminal windows and fresh Claude Code sessions
• Running stty echo and reset commands do not fix the issue
• Reinstalling/restarting Claude Code does not resolve the issue

What Should Happen?

Keyboard input should be visible as it's typed
