Hi,

could you post 'head config.log' from your Weston build directory,
and the log file contents from 'weston-launch &> log.txt'?

Can you exit Weston (or at least make the process exit, even if the
screen does not recover) by pressing ctrl+alt+backspace?

I'm not sure how hard it would be on your distribution, but trying
various old versions of the firmware and proprietary libs (always
use a matching set) you might find a version that works, in case
this is a firmware issue.


Thanks,
