Unable to run X-clients over Weston through XWayland

[Devashish Tiwari]

Hello,

It seems like Weston with Xwayland is still not working for me. Despite of the positive xserver-related prints I get in weston.log file :

---------------

[02:43:02.573] Loading module '/usr/lib/libweston-2/xwayland.so'
[02:43:02.587] Registered plugin API 'weston_xwayland_v1' of size 16
[02:43:02.587] Registered plugin API 'weston_xwayland_surface_v1' of size 8
[02:43:02.587] xserver listening on display :0
[02:43:02.587] launching '/usr/libexec/weston-desktop-shell'

---------------

I am not able to run any X-client within weston-terminal. My $DISPLAY variable is set to  ":0" by default, but as I run any X-client (xclock, xconsole, xhost, xcalc etc.) or any X11 basic sample code I get following error:

Error: Can't open display: :0

I don't know why this error keeps popping up. Can you help?

Thanks,

Devashish

 Hi,

 yes, the usual DISPLAY as always with any X11 stuff anywhere. Weston 
 will set it, so all processes that inherit their environment from 
 Weston will have it readily set, e.g. the launchers you can set up in 
 weston.ini.

 Do note that xeyes specifically will only react to mouse when the 
 pointer is on any X11 window. The X server cannot see any Wayland 
 windows and cannot eavesdrop on input either.

 Thanks,
