Hello all, Just for the record. I googled "$DISPLAY is not set or canot connect to the X server" and found these pages http://forums.gentoo.org/viewtopic-t-852063.html https://bbs.archlinux.org/viewtopic.php?pid=846216 they pointed me to sudo rm -rfv /var/tmp/kdecache-<user> the second page said that it "is enough!", but it wasn't in my case, KDE still does not work. Then I also proceed to sudo rm -rfv /tmp/kdecache-<user> sudo rm /tmp/.Xauthority* (just paranoid) and reboot. Some (or all) of those last commands solved the problem, now KDE returned normally. Thans Joe and Mat for the support. Best regards.
