Started up fine, logged in...still good. I switched the active workspace a few times left/right and then the first monitor blanked. I did it a few more times and then the second monitor blanked. I then physically undocked the laptop, detaching both screens and everything else, to send the captured system reports. Here is a copy of the apport log dump from right after the error occurred: <a href="http://www.crshman.com/debug/apport.xserver-xorg-video-intel.4x6KCY.apport_unpack/">http://www.crshman.com/debug/apport.xserver-xorg-video-intel.4x6KCY.apport_unpack/</a> Also, if you look at the CurrentDmesg file, around [21.961459] is where I pause for a second, then start switching the active workspace back and forth. A few seconds later at [72.034577] is when the first monitor blanks off What other debug information can I grab to help out with this?</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>
