[Kernel-packages] [Bug 1827677] [NEW] Resume from suspend: nothing on display, unable to login
Public bug reported: This is 4.15.0-47-generic on a Dell Latitude 5580. Closing the laptop lid will suspend the system, and opening it will resume, and I normally get my xfce session or the xscreensaver unlock dialog. I recently suspended in this manner, but upon opening the laptop lid, nothing came up on the display. The power button was on, and the keyboard backlight responded to keypresses. Ctrl-Alt-PrtScr-[REISUB] had no discernible effect (PrtScr because I don't have SysRq on this keyboard). Neither did Ctrl-Alt-Del or Ctrl-Alt-F1 for a console. I needed to poweroff and poweron the laptop which of course caused the suspended session state to be lost.

[Kernel-packages] [Bug 1810055] [NEW] Resume fails when suspending laptop with headphones plugged in
Public bug reported: This is Xubuntu 18.04.1, kernel 4.15.0-43-generic on a Dell Latitude 5580. I've found that if I have headphones plugged in when I suspend the system (either by closing the laptop lid, or by using Whisker menu > Power button > Suspend), then the system does not resume properly. It appears that a full boot occurs: Dell logo appears, followed by the Grub menu, and after selecting the boot option and booting, I get a new login session instead of my suspended one. I tried some combinations of booting, suspending and resuming with the headphones attached or detached. The 'yes'/'no' indicates whether the headphones were plugged in when I performed the operation. 'ok' indicates that the resume succeeded: after authenticating to xscreensaver, my previous session was resumed. Boot: no Suspend: no Resume: noResult: ok Boot: no Suspend: no Resume: yes Result: ok Boot: no Suspend: yesResume: noResult: fail Boot: no Suspend: yesResume: yes Result: fail Boot: yes Suspend: noResume: noResult: ok Boot: yes Suspend: noResume: yes Result: ok Boot: yes Suspend: yes Resume: noResult: fail Boot: yes Suspend: yes Resume: yes Result: fail (Note: for each case, the suspend was done via Whisker menu > Power button > Suspend) The common factor for failure is suspending when the headphones are plugged in.

[Kernel-packages] [Bug 1763594] Re: xhci hangs; reset results in NULL pointer dereference
I've been getting similar disconnects on a Dell Latitude 5580 that is connected to a Dell D6000 docking station via USB-C. I'm also using DisplayLink driver version 4.4.24 (https://www.displaylink.com/downloads/ubuntu) in order to connect to two external displays. With Ubuntu 17.10 I was not seeing any disconnects.
