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. Philippe
