[SOLVED] LENOVO E595: Black screen on resume from suspension.

Suspending the laptop is not the issue I am experiencing but waking the laptop after suspension is what breaks. The laptop wakes up to a black screen without a functioning system, not even CTRL+ALT+BACKSPACE works. The issue is similar to https://bbs.archlinux.org/viewtopic.php?id=249510 and therefore I have tried all the solutions mentioned in that thread (before knowing of its existence). I also tried the Early KMS solution mentioned in the thread, which I did not think of and the result is the same. Solutions mentioned in https://wiki.archlinux.org/index.php/La … o#E_series have also been tried but the problem remains unsolved.

Something worth mentioning is that the laptop has to go through suspension and waking up twice for the system to return to normal, but this solution does not work all the times and has unfortunately caused me loss of important data.

Logs:
1. https://git.io/Jer5J (lshw -short)
2. https://git.io/Jer7H (Journalctl --since="1 hour ago", note that this journalctl includes several boots because I was trying to include the functional two suspends for the system to work again)
3. https://git.io/Jer7S (dmesg)
4. https://git.io/Jer79 (Xorg.0.log)

Your amdgpu module is crashing hard. Try and hope for a BIOS/UEFI firmware, otherwise you might want to check the 5.4 kernel https://aur.archlinux.org/packages/linux-mainline

Damn, did not know that.. I apparently need to learn how to read my logs properly.
Thanks for the heads up btw and I will have a look at upcoming UEFI firmware updates because it wasn't long ago I updated the UEFI firmware.

FWIW something else you might be able to try now is disable a few power saving things in the kernel module and check whether behaviour improves

amdgpu.dc=0 amdgpu.dpm=0 amdgpu.aspm=0 amdgpu.runpm=0 amdgpu.bapm=0

on your kernel parameters. If that fixes a resume attempt, try to remove them one by one until you've identified a (few) potentially contributing culprit(s).

Will do that tomorrow and report back after testing for the sake of helping someone else with the same issues. Thank you for enlightening me about those temporary solutions that could fix the problem!

Since I am not very active in forums as I am in discord, I would like to make an update on this matter. The problem was resolved with the help of a Linux kernel update and thus I have been able to suspend and resume from suspension for the past couple of months! Thank you to everyone who tried to help me out, I kindly appreciate it!
