I recently reinstalled my Arch Linux desktop onto a brand spankin’ new solid-state hard drive. I’ve been extremely happy with the performance, but I was having problems with X11 forwarding over SSH.
aorth@dspace:~$ meld Invalid MIT-MAGIC-COOKIE-1 key/usr/lib/pymodules/python2.6/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display warnings.warn(str(e), _gtk.Warning) /usr/bin/meld:111: GtkWarning: gtk_icon_theme_get_for_screen: assertion `GDK_IS_SCREEN (screen)' failed gtk.icon_theme_get_default().append_search_path(meld.paths.icon_dir()) Traceback (most recent call last): File "/usr/bin/meld", line 111, in
gtk.icon_theme_get_default().append_search_path(meld.paths.icon_dir()) AttributeError: 'NoneType' object has no attribute 'append_search_path'
It was happening on both CentOS and Debian remotes, both of which were working when SSH’d from other machines.
The solution is to install
sudo pacman -Sy xorg-xauth
I guess I’m just used to Debian-based distros where
xauth was preinstalled (or alongside Xorg, I suppose?). Anyways, that’s what’s up. 😛
