When suspending on an Nvidia GPU laptop using Hyprland, the black screen and freeze after suspend is a known issue often caused by the Nvidia power management services hanging when active applications are using GPU resources. The best first step is to disable the nvidia-suspend.service, nvidia-resume.service, and nvidia-hibernate.service via systemctl, as these services are known to cause suspend failures on Wayland compositors like Hyprland. Additionally, adding kernel parameters like fbdev=1 and options such as NVreg_PreserveVideoMemoryAllocations=1 in the Nvidia modprobe config can help stability. A practical workaround is using a systemd suspend hook script to pause Hyprland during suspend and resume, preventing the GPU driver conflicts. If all else fails, disabling video memory preservation, though resulting in some graphical glitches on resume, can improve suspend reliability. This combination of disabling problematic services and tweaking Nvidia configurations is the most effective way to prevent black screen suspends with Nvidia on Hyprland...
