Huge RAM usage when using nvidia-smi

After upgrading to nvidia-driver-555-open and Ubuntu 24.10 daily builds, as soon as I launch nvidia-smi, my RAM usage (not VRAM) goes to 99% with nvidia-smi using all the available memory and taking forever to actually display the stats

It looks like there’s a problem with the nvidia-driver-555-open on Ubuntu 24.10 daily builds. Here are a few things you can try:

Update Everything: Make sure your system and drivers are up to date.

Revert the Driver: If the issue started after updating, try going back to an older, stable version of the NVIDIA driver.

Reinstall the Driver: Completely remove the current driver and reinstall it:

sudo apt-get remove --purge ‘^nvidia-.*’
sudo apt-get install nvidia-driver-XXX

Replace XXX with the version number you want to install.

Check Logs: Look for errors related to NVIDIA by running:

dmesg | grep nvidia

or check /var/log/syslog.

Run Memory Test: Make sure your RAM is working properly using memtest86.

Ask for Help: If none of these work, try asking on NVIDIA forums or contacting their support.

These steps should help identify and fix the issue with nvidia-smi using all your RAM.

Run

sudo mv /usr/lib/systemd/system/nvidia-persistenced.service /usr/lib/systemd/system/nvidia-persistenced.service.disabled

I had same issue and it will may fixes your issue.
