This time I used Dell U2311Hb DP monitor to workaround <a class="bz_bug_link bz_status_NEW " title="NEW - [BSW] ASUS PA238Q DP screen is black after system boots" href="show_bug.cgi?id=90006">bug 90006</a>. After resuming, DP screen is black. I tried to hotplug, power off/on DP monitor, and run "testdisplay -i", but the screen is still black. "testdisplay -a" will make the screen recover. I also tried S3 after X is started, the screen is black too after resuming. I can recover the screen by running 'xrandr --output DP1 --set "Broadcast RGB" Automatic/Full' to switch "Broadcast RGB" property.</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> <li>You are the assignee for the bug.</li> </ul> </body> </html>
