Hi Cesar,

just to update you: due to graphics team being currently fully busy with some high priority tasks in the following 3-4 weeks the response rate from them might be very slow. We will try to prioritize the E2E forum after that period.

Hi Cesar,

We have seen this issue at times. There seems to be a race condition in initializing Graphics driver and Weston.

Can you confirm if you see the same problem if you do the following?
/etc/init.d/rc.pvr start

Hi Cesar,

In addition, please let us know if you see the problem after every reboot? Or only during very first boot with a new file system.

Anand
