FreeBSD 7, KDE 3.5 To install Matlab (in linux compat mode), one must execute the matlab install program as root. The installer is graphical. When from a KDE terminal window, I switch to root (# su -) and try a graphical program, e.g. # xpdf, I get Can't open display. The FreeBSD handbook (10.5.1) says in that case type setenv HOME ~USER (USER the username where the su command was given). This doesn't help I still get Can't open display. What's wrong and how to solve it?
