Hello, friends.

Right now it's 12:14 AM on June 19, 2026, Beijing time.

I'm a Chinese 8th grader, learning to use Kali Linux. But when I type "kex," a VNC window flashes for about 7-8 seconds and prompts me to enter a password, yet the window freezes.

I've tried 2-3 times, but still couldn't get it to work. Suddenly I looked at the taskbar and saw a window showing [WARN] COPY MODE.

I don't know how to fix it.

My computer is a Lenovo Legion Y7000 laptop, running Windows 10.
The WSL version is WSL 2, maybe with WSLg.

Ummm,I want to ask a question.
If using root permission influence the result?
