I have now retested the problem commit cb75d97e and it's parent 70790f4f, both with 3bb076af cherry-picked. Things just get more complicated... Although the fade-to-black problem hasn't changed, including 3bb076af makes the previously working parent commit exhibit the 'hsync' problem I described before! All tests include the dpms-fix patch from <a href="show_bug.cgi?id=56461#c19">comment 19</a> to prevent the original hard-hang problem. In summary: 1) 70790f4f + dpms-fix - works 2) 70790f4f + 3bb076af + dpms-fix - the 'hsync' problem reappears! 3) cb75d97e + dpms-fix - fades to black 4) cb75d97e + 3bb076af + dpms-fix - fades to black There's quite a bit of difference in the console logs between 70790f4f & cb75d97e, but nothing obvious (to me). I'm attaching console logs for cases 1, 2 & 4.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
