Dear Maintainer,

System Information:

OS: Debian 13 “Trixie” (fresh upgrade from Debian 12)
Driver Version: 550.163.01
Display Server: X11
Kernel: 6.12.48+deb13-amd64
Problem Description:
After upgrading from Debian 12 to Debian 13, monitors do not wake up after
suspend. The system appears to resume (fans spin up, lights come on) but
displays remain black and unresponsive.

Reproducible Steps:

Fresh Debian 13 installation with NVIDIA 550.163.01 drivers
Run sudo systemctl suspend
Wake system (keyboard/mouse/power button)
Result: Black screens, system appears hung
Key Finding:
Uninstalling NVIDIA drivers completely resolves the issue - suspend/resume
works perfectly with nouveau drivers.

Attempted Solutions (all failed):

Added nvidia.NVreg_PreserveVideoMemoryAllocations=1
Added nvidia.NVreg_EnableS0ixPowerManagement=1
Added nvidia.NVreg_EnableGpuFirmware=0
Enabled nvidia-suspend.service, nvidia-hibernate.service,
nvidia-resume.service
Installed nvidia-suspend-common package
Expected Behavior:
Monitors should wake up properly after suspend, as they do with nouveau
drivers.

Additional Notes:
This appears to be a regression - suspend/resume worked fine on Debian
12 with
earlier NVIDIA drivers. Issue persists with X11 (not Wayland-specific).

I will attach nvidia-bug-report.sh output if this helps with diagnosis.

I also tried the linux-image-6.16.3+deb13-amd64 kernel from the
backports repository, but the issue persisted.

Hello Mika

Have to two desktop computers here. Both Debian 13, Xfce, Asus
motherboard, AMD CPU and Nvidia GeForce GT 1030. One shows same behavior
as described > black screen < after resuming from suspend. The other
computer resumes without showing that issue.

Besides reverting to nouveau the other solution for me is using the
other Nvidia driver to be found in the Debian resources I can use for
those GeForce GT 1030 boards. nvidia v: 535.274.02

https://wiki.debian.org/NvidiaGraphicsDrivers#Version_535.216.03

The Wiki does not seem to be up to date, but

# apt install nvidia-tesla-535-kernel-dkms nvidia-tesla-535-driver
firmware-misc-nonfree

installed 535.274.02 here and this one works resuming from suspend.

Dear maintainer,

I am using xfce4 with the nvidia-driver.

After upgrade from debian 12 to debian 13, I encountered the same problem:
the system does not resume properly: the system wakes up but the screen stays black,
keyboard is unresponsive and system does not reply to ping.

I similarly tried with the nouveau driver: it also solved the suspend/resume problem.
However, the nouveau driver has problems making it not usable: (system crash, wrongly
drawing things e.g. in firefox.


I found that doing:
  sudo systemctl disable nvidia-suspend.service
  sudo systemctl disable nvidia-hibernate.service
  sudo systemctl disable nvidia-resume.service
solves the problem.

I am not too sure what the below implies (e.g. is the GPU really powered down ?)
but at least with the above, I could successfully suspend and resume several times.
