Hello

This script


 graphics_toolkit("gnuplot")
 close all
 setenv("GNUTERM", "qt")
plot([0 1],[0 1]);

 returns the error

(gnuplot_qt:20247): IBUS-WARNING **: Unable to connect to ibus: Could not connect: Connection refused

​gnuplot_qt is a separate process from gnuplot. This kind of error happens when the communication between the two gets broken by some violent and unclean methods. Try to reboot computer and see if the problem goes away.​

Unknown or ambiguous terminal name 'qt'

​This just means that your gnuplot binary does not have qt terminal. Plot will show up on whatever default terminal is (X11 or wxt most likely). You need to install gnuplot-qt package and make sure the binary from that package is executed by octave. ​
