When I suspend my Laptop it suspends fine (takes a bit until the fans turn off), but when I wake it there's only a static underscore at the top left and i have to hold the power button to restart the laptop.
I am running the
4.15.0-1024-oem kernel on Ubuntu 18.10 with the proprietary nVidia drivers 390 installed via the Software & Updates GUI, on an nVidia Quadro P2000. I have tried the 410 drivers with the 4.19.1 kernel but that yields the same result. The only time it worked properly was on kernel 4.19.1 before I installed the 410 drivers, and the 390 were incompatible with the kernel and therefore not loaded.
glxinfo | grep OpenGL
yields the following
