crs, 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-X.Y-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-X.Y-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: needs-bisect ** 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/1454160 Title: External monitor is disabled after resume Status in linux package in Ubuntu: Incomplete Bug description: I have an external screen connected to my machine (T450s, via docking station) and after resuming from suspend, my external monitor is disabled. After some trial and error I made an interesting observation: The external monitor only stops working if suspend via systemctl suspend, sudo pm-suspend, or via the hotkey on my keyboard (K750). However, this problem does not occur if I suspend via the menu entry in the upper right corner. How is this even possible? Mapping the suspend command from the upper right corner to a hotkey would be a sufficient workaround. But which command is used by that button?
