Description of problem: [newman@localhost ~]$ gnome-shell xauth: creating new authority file /tmp/gnome-shell.RpM3Bp/database Could not find Xephyr. Version-Release number of selected component (if applicable): gnome-shell-2.27.0-4.x86_64 How reproducible: always Steps to Reproduce: 1. Install gnome-shell as a new package 2. run it from GNOME (still running gnome-panel) Actual results: denial of execution Expected results: shiny running gnome-shell Additional info: Installed Xephyr and gnome-shell tried to start, at least.
Intentional, spec file has: # These are needed to run gnome-shell nested Xephyr mode, but that's a # developer-only thing and unlikely to be interesting for a normal user #Requires: xorg-x11-server-Xephyr #Requires: xorg-x11-xauth Xephyr was a red herring - you really didn't want to run it in Xephyr - it's slow and doesn't really show the experience. The current behavior is pretty confusing - we should require an explicit command line. Filed that upstream as: https://bugzilla.redhat.com/show_bug.cgi?id=518948 As for how to switch, there's a new desktop-effects package in the pipeline https://www.redhat.com/archives/fedora-desktop-list/2009-August/msg00119.html Until then the best way to try out the shell is mkdir -p ~/.config/autostart ln -s /usr/share/applications/gnome-shell.desktop ~/.config/autostart [ Log out and log back in ] Delete the link to go back to normal GNOME. There's also 'gnome-shell --replace', but that triggers a bug in Metacity so you don't want to use it (fix also in the pipeline, see: http://bugzilla.gnome.org/show_bug.cgi?id=588119)
