Public bug reported: 1. Install Ubuntu 18.04.2 LTS with linux-oem-osp1 kernel, xserver-xorg-hwe-18.04 and nvidia-driver-440. 2. Select the performance mode in NVIDIA settings and reboot the system. 3. Connect dell-wd19tb-dock to the system. 4. Connect external HDMI monitor to dell-wd19tb-dock. 5. Open a terminal, some GUI applications and then execute `systemctl suspend` in the terminal. 6. Disconnect dell-wd19tb-dock after the system fell asleep. 7. Resume the system and login the GNOME desktop environment.
Expected result: The terminal and other GUI applications will still exist. Actual result: All opened GUI applications in GNOME are gone.
