I did some testing of the previously mentioned ppa:ricotz/staging under Precise. It is not at all usable. Due, I believe, to problems in gtk+, not the packaging. ricotz tells me that enabling both the wayland and x11 backends for gtk+ is just broken.
Without adding a ~/.xsessionrc, X does not start. After adding ~/.xsessionrc containing export CLUTTER_BACKEND=x11 export GDK_BACKEND=x11 X didn't start on startup, but did start when I ran startx. Didn't do much other than notify me that nautilus crashed and ask me if I wanted to report it. I tried running gnome-terminal from the console. It gave me the expected error that DISPLAY wasn't set, so I set it (export DISPLAY=:0). Then it gave a XDG_RUNTIME_DIR not set warning, which is a wayland thing. So I set the above two BACKEND variables in that shell, and tried again, and gnome-terminal gave me: Gdk-CRITICAL **: gdk_wayland_device_get_selection_type_atoms_libgtk_only: assertion `GDK_IS_DEVICE_CORE (gdk_device)' failed Before doing any of this, I recommend: apt-get install ppa-purge Also, if you end up at a text console that isn't responding to your keyboard, do alt-sysrq-r. And if you need to switch between nvidia proprietary and nouveau drivers from the console because X won't start, you can use jockey-text, although it looks like it doesn't update /etc/X11/xorg.conf, which is necessary, so have working backup copies of that file. You should also know about rebooting via alt-sysrq reisub, although I haven't had to do that in this process. What I did was, freshly install Precise, then: sudo apt-get update && apt-get dist-upgrade sudo add-apt-repository ppa:ricotz/staging sudo apt-get install libcairo2 libcairo-gobject2 gir1.2-gtk-3.0 libgail-3-0 libgtk-3-0 libgtk-3-bin libgtk3-common Then to revert: sudo ppa-purge ppa:ricotz/staging I also came across a weird bug where a third line containing "ain" was showing up in /etc/apt/sources.list.d/ricotz-staging-precise.list, probably an add-apt-repository bug. Just edit that file and delete that line. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/954352 Title: Enable wayland backend Status in “gtk+3.0” package in Ubuntu: Confirmed Bug description: Add --enable-wayland-backend to build flags. I believe this is all that's necessary for wayland to work with the existing Precise gtk packages. Wayland has one released version, 0.85, which is in the precise archives: https://launchpad.net/ubuntu/+source/wayland/ I'm told gtk 3.4 is (and will remain) compatable with it. Since gtk 3.4 is apparently already packaged for Precise, all that remains to be able to use some gtk applications via wayland is this build flag.
