Frank Boßmann, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to 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 by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-3.XY-rcZ Where XY and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-3.XY-rcZ 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 ** Tags added: bios-outdated-1.15 ** Tags removed: bios-outdated-1.15 ** Tags added: latest-bios-1.17 ** Changed in: xorg (Ubuntu) Importance: Undecided => Medium ** Changed in: xorg (Ubuntu) Status: New => Incomplete ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- 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/1402360 Title: Keine Hdmi- Anschluss mehr möglich/No HDMI connection possible Status in linux package in Ubuntu: Incomplete Bug description: Seit dem Update auf Kernel 3.13.0-43 generic kann ich kein Hdmi-Gerät mehr anschließen. Wenn ich das Kabel einstecke, wird das Display schwarz, am Gerät kommt keine Signal an und ich kann auf meinen Rechner nicht mehr zugreifen. Weder abziehen des Kabels noch Fn+F7 noch irgendeine andere Tastenkombinatione helfen etwas, nur ein Neustart bringt eine Lösung. Wenn ich über GRUB mit dem vorherigen Kernel starte (3.13.0.-40 generic) funktioniert alles normal. Freundliche Grüße Frank Boßmann After updating to kernel 3.13.0-43 generic I can not connect a hdmi device more. When I plug in the cable, the screen goes black, the device comes at no signal and I can not access my computer. Neither pull the cable still Fn + F7 keys nor any other combinations will help a little, just restart brings a solution. When I start over GRUB with the previous kernel (3.13.0.-40 generic) everything works normally.
