problematic trait of mine: i actually like the Linux NVIDIA graphics driver. it's always worked really well for me, it's fast, it's got good compatibility with games i run under wine, it handled render offload, hotplug, and hot-unplug of GPUs (less so the latter but to an extent) about as well as you can do with Xorg
nvidia.ko is one of the most singularly reviled things in the broader Linux sphere, maybe even more so than systemd, and honestly i don't think it deserves that level of hate
people don't like that NVIDIA management chose to allocate resources in such a way that they ship a copy of their Windows graphics stack entirely parallel to any community efforts on Linux, and that's a fair thing to disagree with, but it's hard to argue with the utility of having basically the same codebase (except for the HAL) on both platforms because it means that if a game works on Windows it will probably work under wine too
@whitequark To be honest, while everyone complains about Nvidia drivers on Linux, they've always worked perfectly and with good performance for me. Having my games library Just Work is worth a fair bit of ugliness under the hood to me.
