[Kernel-packages] [Bug 1165965] Re: External display stopped working
I can also confirm that it works more reliable with 3.12.0-031200rc6-generic (and 3.12.0-031200-generic), but it is still not perfect. I would have to ability to test it on two cases where it does not work. Both are beamers (different models, I have to check which one exactly) and both are connected over very long VGA cables. This is still an annoying bug, at least there was some progress so that it started to work again for most monitors I tried. Now it would be nice to get it working on beamers too. Can I do something to test this? I have checked the dmesg messages and there are no messages like [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up what happened before kernel 3.12 (and maybe kernel 3.11.4). From xrandr output I noticed, that the DP1 connector is shown as disconnected and also no modes are shown (before kernel 3.12 there was sometimes a resolution of the external monitor detected). -- 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/1165965 Title: External display stopped working Status in “linux” package in Ubuntu: Confirmed Bug description: After upgrading to 13.04 beta, my external monitor is no longer detected/driven.

[Kernel-packages] [Bug 1165965] Re: External display stopped working
Michael Paddon, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel folder, but the one all the way at the bottom. 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-rc6 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.

Hey guys, Just FYI, I've found a workaround for this issue on 12.04.03 LTS. The fix involves installing kernel v3.12-rc6 suggested by Christopher. I had wireless and keyboard issues but they were minor fixes. See details in posts #6 #7: https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1242013 My monitor is working with the DP to VGA, wifi and keyboard also work fine. Woo. I'll keep testing and post back any updates. You should definitely try it to see if it fixes your issue too. -- 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/1165965 Title: External display stopped working Status in “linux” package in Ubuntu: Incomplete Bug description: After upgrading to 13.04 beta, my external monitor is no longer detected/driven.
