** Description changed: After upgrading to kubuntu 18.04 resuming from suspend fails in most cases on my laptop. When trying to resume the power LED is turned on, but the screen stays black and the system does not respond at all. Switching to another virtual terminal is not possible and closing the lid again does not show any effect. The hardware is a Dell Latitude e7440 with core i7 4600U and intel graphics only. The only way to change the status is a hard shut-down by long pressing the power button. The last message in kern.log is: PM: suspend entry (deep) The described problem is similar to bug #1774950. However, the latter is considered to be fixed with kernel 4.15.0-38 while my problem persists with this kernel. Output of 'sudo lspci -vnvn' is attached, the result of 'cat /proc/version_signature' is: Ubuntu 4.15.0-38.41-generic 4.15.18 + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.4 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: graeser 2116 F.... pulseaudio + /dev/snd/controlC0: graeser 2116 F.... pulseaudio + CurrentDesktop: KDE + DistributionChannelDescriptor: + # This is a distribution channel descriptor + # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor + canonical-oem-somerville-precise-amd64-20130203-1 + DistroRelease: Ubuntu 18.04 + EcryptfsInUse: Yes + HibernationDevice: RESUME=none + InstallationDate: Installed on 2014-03-20 (1690 days ago) + InstallationMedia: Ubuntu 12.04 "Precise" - Build amd64 LIVE Binary 20130203-13:50 + MachineType: Dell Inc.
