I know Ubuntu works with the nvidia-* drivers but does it detect and select them for use by default or does it use nouveau until a (knowledgable) user reconfigures which driver is in use? And with legacy nvidia such as 340 there isn’t Wayland support and so enabling by default could lead to a broken system. Same with a kernel greater >= 5.10 and that particular driver series. So would be nice to hear what Pop OS is doing here that Ubuntu isn’t. If the rumours of nvidia open sourcing their drivers are true (sorry no link - just something I heard) they’ll all work out of the box one day (hopefully !).
