Hi,
Can you clarify a few things please..
I tried running the application again
The error i m facing is not constant.
Sometimes, i do get the HTML screen. That means it is creating a wl shell.
So when i launch weston, 3 out of 10 i get html page. But for the other 7
times, i get a blank screen.
So what i see is some instability..
When i had tried to launch the screen without weston, there is no problem
in the launch.
Thanks,
Sathish
