Can't be sure there is one of course, but supposedly we should have some way to figure out the panel timings and I can't think of another method we're missing. If this fails, I suppse the final option is to just ignore the VBT in case the LVDS is already on when the driver loads and just use the current timings. Totally untested so might blow up or something.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
