NVIDIA Driver Troubleshooting Guide - Lemmy.world

Driver status To check if you have a functioning driver, run nvidia-smi in a terminal. If the driver is functioning, it will actively report the GPU(s) it found on the system, and the version of the driver loaded. $ nvidia-smi Tue Jul 25 22:14:24 2023 +---------------------------------------------------------------------------------------+ | NVIDIA-SMI 535.86.05 Driver Version: 535.86.05 CUDA Version: 12.2 | How to reinstall If this is not working, purge and reinstall the drivers on the system. sudo apt purge ~nnvidia sudo apt install nvidia-driver-535 Freezes and suspend/resume issues These are most typically related to power management. You can try out different driver options by creating a file in /etc/modprobe.d/, such as a hypothetical /etc/modprobe.d/zz-nvidia.conf. > Some of these are automatically generated by system76-power when switching between graphics modes. So if you are manually setting these, be wary that these can conflict with different modes, or the system76-power.conf will override your settings if your file’s name comes alphabetically before it. All systems should have at least this defined: options nvidia-drm modeset=1 — For hybrid graphics, it may be necessary to define blacklist i2c_nvidia_gpu alias i2c_nvidia_gpu off options nvidia NVreg_DynamicPowerManagement=0x02 — If the hardware has issues with GC6, change DynamicPowerManagement to options nvidia NVreg_DynamicPowerManagement=0x01 — Some issues have issues with resuming from S3 sleep, which needs options nvidia NVreg_PreserveVideoMemoryAllocations=1 — Worst case scenario, you can try disabling these sudo systemctl disable --now nvidia-hibernate.service nvidia-resume.service nvidia-suspend.service I found a workaround Do share what solutions for your hardware; the graphics card model you have; and if it is a laptop, the DMI IDs that could be used to ID a system to automatically apply a known workaround. You can run this script in a terminal to print the DMI info: for dmi_file in /sys/devices/virtual/dmi/id/*_{name,version}; do echo $dmi_file; echo -n ' '; cat $file done
