I usually upgrade my system a few months after a release so bugs like this are identified and have plenty of time to be fixed before I upgrade. I just upgraded from 13.04 to 13.10 and ran into this exact bug (and currently stuck only being able to use two of my three monitors). It is unfortunate that this bug was identified and mostly tracked down then stalled without getting fixed.
As a user of Ubuntu, I would most certainly like to answer the question from Christopher "Would you need a backport to a release prior to Trusty" with a resounding YES! Please backport the fix in the kernel to the current "production" release of Ubuntu, Saucy Salamander (13.10). It seems like Roger was very willing to try other 3.12 kernels to narrow down the bug fix and it would be great if Timo or whoever would continue working with Roger to narrow down the problem so it is easier to identify the bug fix and backport it to the current Ubuntu release. I would much prefer to use the currently supported kernel instead of running a pre-Ubuntu-release kernel. But in the mean time, Roger, please share your notes in the comments with the workaround you are using to run a newer kernel with the fix (that is also hopefully stable), thanks! Christopher, can you please reclassify the status of this bug and put in the request to have the fix backported? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1242180 Title: saucy regression - three monitors no longer work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1242180/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
