Its cuz setdisplay sends the ioctl to the wrong device. It should be
setdisplay -d /dev/tty
to send it to the current tty or ttyv<n> to change a specific one.
If you do that then the mode will be changed for that terminal. There
used to be a -a switch to change all of them but it seems to have been
omitted in later versions.
