This is definitely not true! 2) Once booted in standalone mode, if I then proceed to plug in the DisplayPort connector then the kernel throws a backtrace - I'll upload this as a separate attachment. My best guess is that the freeze is related to trying to enumerate these non-existent DisplayPort outputs when starting X. Whereabouts in the code are these outputs parsed/enumerated?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
