Peter T Hayward, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.12 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: kernel-needs-upstream-bug-report kernel-request-3.0.0-12.20 ** Tags added: bot-stop-nagging needs-upstream-testing ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/863969 Title: ubuntu 11.10b2 resumes on wrong iMac display port Status in “linux” package in Ubuntu: Incomplete Bug description: My iMac 21.5 (11,2) has ubuntu 11.10b2 installed, dual boot with Osx Lion. Ubuntu uses the open source ATI drivers At boot the video is good: on main display, correct resolution, reasonable performance. Resuming from sleep the system switches to the external video port (nothing connected) and leaves the main screen unlit. If I plug second monitor onto the external port I can continue after resume. On external screen the X resolution is as if for the main screen (1920x1080); incorrect for external screen (should be 1280x1024). I have no way to relight the main display, except restart. This issue of wrong display port used to affect ubuntu booting on iMac (see #542660 & #597070) but that problem seems to have been tamed in Oneiric. However not being able to resume without a second screen is a problem, especially since the higher power consumption in Oneiric (+15w compared with OSX) means you would like to sleep when possible. From earlier discussions this seems likely to be something fairly complex in KMS code.
