I ran into the same problem after uprading to 24.10. Both nvidia- driver-555 and nvidia-driver-560 show this behavior on my mobile GeForce RTX 4070.
Another issue I noticed, which might or might not be related, is that "ubuntu-drivers devices" takes quite a long time to return its list: $ time ubuntu-drivers devices == /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 == modalias : pci:v000010DEd00002860sv00001558sd0000A661bc03sc00i00 vendor : NVIDIA Corporation model : AD106M [GeForce RTX 4070 Max-Q / Mobile] driver : nvidia-driver-550-open - third-party non-free driver : nvidia-driver-555-open - third-party non-free driver : nvidia-driver-535-server-open - distro non-free driver : nvidia-driver-560 - third-party non-free driver : nvidia-driver-550 - third-party non-free driver : nvidia-driver-560-open - third-party non-free recommended driver : nvidia-driver-555 - third-party non-free driver : nvidia-driver-535-server - distro non-free driver : xserver-xorg-video-nouveau - distro free builtin real 1m57,188s user 0m29,195s sys 1m27,982s using 100% CPU during the process: 21410 andre 20 0 167804 151348 63796 R 100,0 0,2 1:50.18 ubuntu-drivers -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2084987 Title: nvidia-smi is slow and has massive memory leak on upgrade to 24.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-560/+bug/2084987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
