Also we fire off a uevent which causes the DE to query the outputs which fails to detect the DP causing it to switch off the external. On the next uevent, it finds the DP again, causing the DE to re-enable the extended desktop. Also repeat ad nauseam.</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>
