Update - something in the upgrade from Maverick to Natty appears to be the culprit for me. Good thing I made a complete backup prior to this upgrade.
I used the Alternate CD ISO to upgrade to Natty since the online Natty repository wasn't available.. Then I immediately used the online distribution upgrade to upgrade to Oneiric and it was during this install process that the my monitors first shut down (still running Natty). I updated and upgraded and distribution upgraded to Precise and when that didn't fix the problem, I did the same to Quantal. That still didn't solve the problem. Since I spent the better part of a week screwing with this problem and never getting it fixed, I had to trash that entire system. A fresh install of Precise on that same hardware did not have the problem. Clearly this bug is a huge upgrade blunder. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/30969 Title: monitor suspends regardless of gnome-power-manager timeouts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/30969/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
