This bug affected me on Lucid as well. $ apt-show-versions |grep ssh openssh-client/lucid-updates uptodate 1:5.3p1-3ubuntu4 openssh-server/lucid-updates uptodate 1:5.3p1-3ubuntu4 ssh-askpass-gnome/lucid-updates uptodate 1:5.3p1-3ubuntu4
$ grep X11 /etc/ssh/sshd_config X11Forwarding yes X11DisplayOffset 10 The only setting I needed to change was to set SSH_OPTS=-4 in /etc/defaults/ssh and /etc/init.d/ssh restart. Then I logged out and logged in again, and echo $DISPLAY localhost:10 I was connecting from a Mac running OSX 10.6.4 with the stock apple X11 and xterm. -- X11 forwarding via SSH does not work after upgrade to karmic https://bugs.launchpad.net/bugs/434799 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
