Sleep Mode Unusable After Hardware Changes

General system Kernel, boot, graphics & hardware

Let’s get right into it. Sleep never worked correctly on my old hardware but I assume for different reasons. I disabled the 3 nvidia suspend, hibernate, and resume services (Previously i5/nvidia system, now amd system)

Now my sleep mode will just turn off my display, and seems like it does nothing else. Before I disabled the nvidia services, it would instantly resume and I could hear 2 distinct power off/on clicking sounds (from PC). Now I hear 0 power sounds and my display is off. I try ALT T
→ reboot (while nothing displayed) → which turns the display on but leaves my PC in a bugged state (blank black screen). I have to hit my reset button on my case to get it back to normal.

Unsure of how to proceed. I find similar issues but for older versions using grub.

Systemd-boot or grub?

  • systemd-boot - check /etc/kernel/cmdline for any references to nVidia

  • grub - same - check /etc/default/grub for the same and rebuild grub.

Other than that I have no experience with AMD (I have two, one is always on, the other works well, but both are iGPUs).

I’m using systemd. Found nvidia-drm.modeset=1 and gonna remove it

update: I removed the line. Now I’m back to hearing 2 power off/on clicks within the same second.

Even using auto sleep, the machine still instantly wakes up.
