Public bug reported:
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
