Description Antonio Trande 2016-02-10 15:42:44 UTC
Hi all,

user reported a crash of snappy on Fedora 23 with Gnome Wayland:

$ snappy 
(snappy:10392): Clutter-Gtk-ERROR **: *** Unsupported backend.
Trace/breakpoint trap (core dumped)


To me, snappy does not crash with Gnome.

Compiled commit e73fabce4c397b40d490c74f6a6a0de000804f42.

Comment 1 Antonio Trande 2016-02-10 15:45:44 UTC
snappy works with:

```GDK_BACKEND="x11" snappy```
Comment 2 Simon THOBY 2016-02-10 16:04:52 UTC
I'm the user who encountered the crash, do you want me to provide some more infos or debug the program (still lacking a little of experiencein that domain) ?
Comment 3 Luis de Bethencourt 2016-02-16 17:21:53 UTC
Thanks for the information Antonio!

Simon, Antonio is offering a solution. Maybe he can give a bit more context of how to use it for you.

Luis, workaround of comment#1 is by Simon; I don't use Wayland, is GDK_BACKEND= variable usable on any DE?
Comment 5 Andrew Brouwers 2016-10-14 22:54:36 UTC
Just ran in to this, too, since wayland is the default in gnome 3.22!
