Issue/Bug Description:
When trying to wake the system from suspend, it hangs on a black screen.

Steps to reproduce (if you know):

1. Put the computer into suspend using the suspend item in the top menu next to the shutdown button.
2. Wait until the computer suspends entirely.
3. Tap the power button to wake from suspend.

Expected behavior:
I expect the computer to wake from suspend normally, however it seems to hang with a black screen until I force a shutdown by holding the power button.

Other Notes:
My computer is a Dell XPS 15 9570.
I have a 1050 Ti MaxQ, and the most recent proprietary Nvidia drivers.

Fixed by adding rcutree.rcu_idle_gp_delay=1 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.

my /etc/default/grub is empty like WTF never had a GRUB file empty in linux xd.

Since 18.04, Pop!_OS has been using sytemd-boot instead of GRUB on all UEFI installations. kernelstub is used to manage adding kernel parameters and the like.

I am new to Linux trying out Pop!_OS 19.10 on my new XPS 7590. I seem to have the same problem when trying to unsuspend using NVIDIA graphics. On freeze, I see the log entry like "GPU has fallen off the bus".

I have tired adding kernelstub arguments based on this thread and another to no avail. I would like to be able to suspend my computer so any help is welcomed :-).

I solved the issue in a different way then what is shown above using the following command to set my kernel boot options:

sudo kernelstub -o "loglevel=0 splash systemd.show_status=false quiet mem_sleep_default=deep"

Specifically, the mem_sleep_default=deep is the parameter to add. I found this solution here.

I "cross-graded" a Ubuntu install to pop on a Thinkpad T430 and had the same issue that mem_sleep_default=deep fixed. Thanks!

Thank you! mem_sleep_default=deep worked for me as well.
