When I start X and work everything is okay, but after some time I cannot execute X programs through terminal! I get the following error. Code: $ xclock No protocol specified No protocol specified Error: Can't open display: :0 DISPLAY=:0 or localhost:0 doesn't work Setting XAUTHORITY doesn't work, too. I also cannot execute from other X opened programs like okular or kate or kwrite though Firefox or Dolphin The error from Dolphin is: KDEInit could not launch '/usr/bin/kwrite' It's like loosing authentication ... Only when I log off/on, everything is fine again! If I reboot the error restarts.
