I have noticed that my gpu-manager claims that: Was nvidia unloaded? yes even though the nvidia module is loaded and was never unloaded (and lsmod displays it). Quick investigation showed that gpu-manager checks whether that module was unloaded by running: dmesg | grep -q "nvidia: module" I assume that the intention was to detect any "nvidia: module unloaded" or similar messages. However, my dmesg contains several other messages that match this pattern: nvidia: module license 'NVIDIA' taints kernel. nvidia: module verification failed: signature and/or required key missing - tainting kernel These messages are not realated to unloading the module, it sucessfully keeps running afterwards. Therefore I believe the pattern used by gpu-manager is incorrect. Possible solution is to correct that search string. The only message that appears in my dmesg when I unload nvidia module is: [drm] Module unloaded The dmesg output never explicitly names `nvidia` when it is unloaded. Another possible solution would be to grep lsmod instead of dmesg, to check if the driver is currently loaded.
