I had the same problem when i use SSH try to change ForwardX11 yes on ur ~/.ssh/config client and X11Forwarding yes in /etc/ssh/sshd_config on server The easiest way is to use MobaXterm on Windows, it works well

i use the easier way: i use the MobaXterm, and it works at the beginning. but i got another problem "ASSERT: "false" in file qasciikey.cpp, line 501" do u get that problem?
