Hi, first sorry for the german in my first mail, shall not happen again.

Please note that this is an english list. Try "sudo" instead, then you don't need to do a "sux root" first...

just tried sudo but it also doesn't do what i want it to do: sre@re001:~> ssh -X re003 Enter passphrase for key '/home/sre/.ssh/id_rsa': Last login: Thu Jul 7 07:31:21 2005 from re001.intern Have a lot of fun... re003 being added to access control list sre@re003:~> sux - Password: re003 being added to access control list re003:~ # sudo -u fjr xpdf X11 connection rejected because of wrong authentication. X connection to localhost:10.0 broken (explicit kill or server shutdown). re003:~ # sudo -u fjr xauth list xauth: timeout in locking authority file /root/.xautho8JfCf the same with su: sre@re001:~> ssh -X re003 Enter passphrase for key '/home/sre/.ssh/id_rsa': Last login: Wed Jul 6 14:41:49 2005 from re001.intern Have a lot of fun... re003 being added to access control list sre@re003:~> echo $DISPLAY localhost:11.0 sre@re003:~> sux Password: re003:/home/sre # set | grep DISP DISPLAY=localhost:11.0 re003:/home/sre # xpdf Warning: Missing charsets in String to FontSet conversion Warning: Missing charsets in String to FontSet conversion re003:/home/sre # sux sre sre@re003:~> xpdf X11 connection rejected because of wrong authentication.
