If you are a laptop user, you may want to avoid driver version 550 because there is a megathread on the NVIDIA forum where users are reporting that this version is making their distributions randomly crash.
550 is the stable driver.. This only started happening in a new kernel version and iirc from some thread it is a bug in the kernel. If you don't have the issue already just not updating kernel until this gets fixed would be enough
Hmm I’m on a HP Omen 15 running Pop!_OS and I’ve found 550 pretty stable. Seems a bit alarmist to say avoid 550 on all laptops, even if there are reported issues.
One of the biggest problems regarding Nvidia drivers is the fact that a small minority install them using Nvidia's .run script, which overwrites important libraries, resulting in a wide range of issues. I've always installed Nvidia drivers using my distro's package manager and I've never had an issue.
