Description Mark Yao 2015-05-22 07:33:08 UTC

Created attachment 115966 [details]
run gtk3-demo with WAYLAND_DEBUG=1

weston version: 1.7.0
wayland version: 1.7.92
gtk+ version: 3.17.1

according to http://wayland.freedesktop.org/gtk.html, run gtk3-demo.　

weston --backend=x11-backend.so

then in weston-desktop-shell:
export GDK_BACKEND=wayland
gtk3-demo

(gtk3-demo:999): Gdk-CRITICAL **: gdk_screen_get_monitor_scale_factor: assertion 'monitor_num < gdk_screen_get_n_monitors (screen)' failed
[16:25:18.644] libwayland: not a valid new object id (5), message get_xdg_surface(no)

(gtk3-demo:999): Gdk-ERROR **: wl_display@1: error 1: invalid arguments for xdg_shell@16.get_xdg_surface

attachment is run command with WAYLAND_DEBUG=1

Is that those weston/wayland/gtk+ version not stable? Can someone tell me a series of packages to run the test?

You are reporting a crash in gtk3-demo, but this it the freedesktop.org bug tracker. Crashes in gtk3-demo should be reported it to bugs.gnome.org.

Anyhow, the crash you are seeing is a version mismatch between the unstable xdg_shell of version 4 in weston 1.7, and the unstable xdg_shell of version 5 in gtk+ 3.17. If you upgrade to the latest RC (released a few days ago) of wayland/weston they will have the same version, or downgrade gtk to some earlier version that shipped with xdg_shell unstable version 4.

Sorry for bad place to report the bug.

I'm new to the wayland, is there a tag or branch to point which version is stable? I compile the gtk/weston/wayland on arm board, very slow for compiling, Hope get less compile to success show a wayland display.

Just in a some days there will be a new stable release of wayland and weston. This will be compatible with both gtk+ 3.17 and the current master branch and gtk+ 3.16.*. If you don't want to wait, just grab the latest release candidate. You can find theme here: http://wayland.freedesktop.org/releases/ where the most recent ones are 1.7.92.

I've downgrade the gtk+ to 3.16.3, but same error again.

I found that there is a error at libwayland:
  "libwayland: not a valid new object id (5), message get_xdg_surface(no)."

That is not old enough. Looking at the git log, you need at least 3.15.6 or older. The easiest thing you can do is probably upgrading wayland/weston to the latest RC.
