I tihnk we need to create a list of machines which need to not use native-backlight even though they claim to be win8 ready, iow start a quirk list which is the opposite of the one we've had until now. This list should be considerably smaller, and thus less work to maintain. Hohahiu's laptop would be the first one on it, and the only one we know about sofar AFAIK.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
