I'm still looking at the jacman problem, and have sometimes found that apps that won't work on the machine they are installed on, will work if I ssh into the machine, and run them on another. IIRC I had problems initially using ssh when I installed Archlinux (don't panic), but found some info somewhere or other, as below. Comment out "ALL: ALL: DENY" line in /etc/hosts/deny Add sshd to /etc/rc.conf daemons list Run /etc/rc.d/sshd start Now I can ssh into archlinux (this is just local, not from the Internet). I have uncommented the following lines in /etc/ssh/sshd_config X11Forwarding yes X11DisplayOffset 10 I can open Xapps as user (gedit, jacman,etc), but not when I su to root, as below for gedit. [djmons@myhost ~]$ su Password: [root@myhost djmons]# gedit X11 connection rejected because of wrong authentication. cannot open display: Run 'gedit --help' to see a full list of available command line options. [root@myhost djmons]# Same goes when I try to open jacman when su'ed to root. I tried accessing Xapps as root with Fedora 8, which is on the same machine as Archlinux, and they open ok. I have compared the sshd_config on both F8, and Archlinux, and can't see any apparent differences between the two. Anyone have any suggestions as to what may be the problem? All a bit puzzling. Nigel.
