Hibernation just sends laptop to login screen (not properly entering hibernation)

General system Kernel, boot, graphics & hardware
1

I have been in love with Endeavor for a few months, I’ve installed it on a multitude of devices, including my new laptop. The laptop is almost perfect, although it has a major issue, it doesn’t hibernate properly, instead, it goes to a black screen with a blinking underscore cursor, the screen goes completely off (keyboard lights stay on), blinking cursor again, and then back to the login. fastfetch tells me I have 2 GPUs:

GPU 1: NVIDIA Quadro P1000 Mobile [Discrete]
GPU 2: Intel UHD Graphics 630 @ 1.15 GHz [Integ]

The laptop is a Dell Precision 5530, please let me know if you have a solution or need more information, thanks in advance!

Anybody have any suggestions?

Try setting up nvidia.NVreg_PreserveVideoMemoryAllocations as described here:

Additionally, some users report blacklisting the nvidiafb is needed for suspend/hibernate with Nvidia hardware. https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Suspend/hibernate_does_not_work,_or_does_not_work_consistently

It may also be worth testing the LTS kernel to see if it makes any difference.

Good news (and sorry to revive a dead thread) but I have found a solution! it’s kind of painful how easy it was but the solution is to simply run sudo rmmod intel_lpss_pci

found the solution here (Stack Exchange).

I will update y’all if any more problems arise bc of the solution.
