In the last months I often had the issue, that resume from hibernate fails. This is probably caused by a configuration issue with my Nvidia GeForce GTX 1050 Ti, but I am not sure. The configuration follows the recommendations in the NVIDIA-Linux-x86_64-545.29.02/README.txt file, chapter "Chapter 21. Configuring Power Management Support". I use the Nvidia RPM drivers 545.29.06 from nvidia-tumbleweed. # cat /etc/modprobe.d/nvidia.conf options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp The "dmesg" output shows a message "PreserveVideoMemoryAllocations module parameter is set. System Power Management attempted without driver procfs suspend interface. Please refer to the 'Configuring Power Management Support' section in the driver README." during resume. # dmesg -T [Wed Jan 10 16:43:51 2024] PM: Using 3 thread(s) for decompression [Wed Jan 10 16:43:51 2024] PM: Loading and decompressing image data (1118391 pages)...
