[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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165965 Title: External display stopped working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165965/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[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.

[Bug 1165965] Re: External display stopped working on MacBook Air
The same problem (external interface DP1 showing as disconnected, sometimes showing the resolutions) happens to me on my Macbook Air 4,2 since already Ubuntu 12.10. This affects also derivatives like Mint and also other distributions like Archlinux. From this I would conclude that it is a general problem with the kernel and/or Intel Xorg driver. The problems depend a little bit on the external monitor that I am using: A normal 19'' LCD with VGA connector works sometimes (after rebooting, suspend/resume, disconnecting/reconnecting). A no-name LCD TV (also VGA connector) doesn't work even with trying all of the things that worked for the 19''. The problems seemed to be gotten worse with Ubuntu 13.04 in comparison with 12.10. With 12.10 I could also get the TV to work after playing around a little bit. As I am using the Air to give talks, this is a major deal-breaker (as also projectors don't work anymore) and the only reason why I still have to boot Mac OS X (there everything works fine). If i can help with logs or testing something, feel free to tell me. Another thing: What I can do is force the monitor to some resolution. As Michael mentioned, the monitor is then switched on, but as xrandr still shows the monitor as disconnected, one can't really use it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165965 Title: External display stopped working on MacBook Air To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165965/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1165965] Re: External display stopped working on MacBook Air
Reports of further experimentation, using kernel 3.8.0-25-generic. Xrandr can see the resolution of my external display, but it shows as disconnected. For instance: I can get the external display to partially work by using xrandr. For instance: $ xrandr Screen 0: minimum 320 x 200, current 3360 x 1080, maximum 32767 x 32767 eDP1 connected 1440x900+1920+0 (normal left inverted right x axis y axis) 286mm x 179mm 1440x900 59.8*+ 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x60060.3 56.2 640x48059.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1920x1080_60.00 60.0* HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) I can enable the external monitor output with: $ xrandr --output DP1 --mode 1920x1080_60.00 --left-of eDP1 This works but xrandr shows the display as still disconnected (exactly the same output as above). Consequently, Unity gets quite confused and windows, title bars and menus don't work as expected. Nevertheless, the underlying display driver seems to be operating correctly. This suggests that the problem is in whichever software layer determines that the external display is connected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165965 Title: External display stopped working on MacBook Air To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165965/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 kernel[0]. You will need to install both the linux-image and linux- image-extra .deb packages. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.
