Hardware: GPU

NVIDIA GeForce RTX 4070 Laptop GPU

Describe the bug

The system consistently fails to resume correctly after suspend.

After waking the laptop:

• displays remain black,
• the session does not recover,
• VT switching does not restore output,
• the issue also reproduces outside Wayland sessions.

The problem occurs:

while running a Wayland session with Niri, and after stopping the graphical session completely and suspending directly from a TTY.

Because the issue reproduces from a pure TTY environment, this does not appear to be compositor-specific.

Reproduction steps

1. Boot the system normally or TTY
2. Run: systemctl suspend
3. Try to wake the laptop

Relevant logs

The following errors appear during DRM/compositor initialization:
nvidia-modeset: ERROR: Invalid request parameters, planePitch or rmObjectSizeInBytes, passed during surface registration

Niri also reports DRM framebuffer failures:

failed to add a framebuffer for the bo
Permission denied (os error 13)

Additional notes

• The issue reproduces even after stopping SDDM and suspending from a plain TTY.
• The issue reproduces with and without external monitor attached.
• SYSTEMD_SLEEP_FREEZE_USER_SESSIONS=true and false were both tested without improvement.
• Kernel log reports:
  Low-power S0 idle used by default for system suspend
• ACPI-related firmware errors are also present:
• ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GPP0.PEGP.GPS.NVD1], AE_NOT_FOUND

To Reproduce

1. Boot the system normally or TTY
2. Run: systemctl suspend
3. Try to wake the laptop

Workaround found

After further investigation, the root cause is that S0ix Power Management defaults to Disabled even when the hardware reports Platform Support: Supported (visible in /proc/driver/nvidia/gpus/0000:01:00.0/power).

The following modprobe config resolves the issue:

sudo tee /etc/modprobe.d/nvidia-power.conf << 'EOF'
options nvidia NVreg_EnableS0ixPowerManagement=1
options nvidia NVreg_PreserveVideoMemoryAllocations=1
EOF
sudo mkinitcpio -P

After rebooting, /proc/driver/nvidia/gpus/.../power shows S0ix Status: Enabled and suspend/resume works correctly.

---

The underlying issue worth fixing at the driver level: on laptops where cat /sys/power/mem_sleep returns only s2idle (no deep/S3 option), NVreg_EnableS0ixPowerManagement should default to 1 automatically when Platform Support: Supported is detected, rather than requiring manual user configuration. Many users will hit a permanent black screen on resume without ever knowing this option exists.
