XPS-15 9570 with Ubuntu 18.04.1 not resuming after suspend

[PDAdiga]

I have installed Ubuntu 18.04.1 in XPS 15 9570. And installed Nvidia driver 390. If I switch to Intel (Power saving mode), the system can resume back after suspending. But If I want to use the GPU by switching to NVIDIA (Performance Mode) through "Nvidia X Server Settings" wizard, I am not able to resume the system after suspending, the laptop just hangs and I have to forcefully shut down by pressing the power button.

I followed the solutions posted here, but no one is working. Even using Bumblebee is not solving the problem. Can anyone help to resolve the issue? What is the basic reason for hanging?

Having the same issue - did you find a solution?

Having the same issue. Blacklisting nouveau and upgrading linux kernel didn't help...Did anyone find a solution?

[tmaila · Accepted solution]

After several days of hitting my head against the wall I finally found a solution: 

• Install official NVIDIA proprietary drivers (nor sure if needed but you probably want to do this anyways)
• Edit /etc/default/grub 

sudo nano /etc/default/grub

make sure that the GRUB_CMDLINE_LINUX line has the following items:

GRUB_CMDLINE_LINUX="nouveau.blacklist=1 acpi_osi=! acpi_osi=\"Windows 2015\" acpi_backlight=vendor mem_sleep_default=deep"

• update grub:

sudo update-grub

• reboot
• after computer has restarted, try suspending to see if the laptop wakes up normally

Haven't tried the workaround yet, but this is without nouveau on archlinux:

I've reported this to nvidia and apparently it's a dell sbios issue.

I will also confirm this  workaround works for archlinux.

I have the same problem! Unfortunately the selected solution is not working. My Ubuntu 18.04 session crashes when resuming from sleep if the Nvidia proprietary driver is used on Performance mode. I have to revert to Power Saving mode (use intel) in order to be able to suspend my laptop.
