Comment 49 for bug 1846374

I can confirm this also happens on elementary OS 6 with nvidia-driver-470. I tried to add a limit to /etc/systemd/journald.conf, but it didn't help at all. Finally I managed to limit the log size using this tutorial:

I still have problems with hight CPU & SSD usage caused by the logging, but at least it doesn't fill my disk entirely.
