Nvidia desktop GPUs may be fine on Linux now, but are very much still trash on Laptops. I can't even begin to express how troublesome they have been on the work laptops I've been forced to use. I would've killed for any non-Nvidia laptop, even if just integrated graphics, but IT won't approve any other models, and the UEFI lacks an option to fully disable the Nvidia GPU.
- ryao 2y agoOn Optimus laptops, I usually disable the Intel GPU rather than deal with GPU switching. Those poor souls that have laptops without a proper multiplexer cannot do that, but I doubt it is a huge problem. With vulkan, you can specify the GPU to use via an environment variable.
- MrDrMcCoy 2y agoThe Optimus-encumbered ThinkPad P16s Gen1 I'm currently stuck with has no exposed option to disable the Nvidia GPU in the UEFI. The environment variable trick, as far as I know, can't be used to prevent the entire desktop from touching the dGPU. Almost all of my issues are related to the desktop compositor crashing or freezing after too many DKMS power events, returning from sleep, [un]docking from my external display, or just plain running for too many hours. I'm on the latest firmware, kernel, and drivers, and it still gives me grief.
- ryao 2y agoBlack list the kernel driver for the Nvidia card if you want to disable it. That said, I wonder if you are using the nouveau driver. The Nvidia driver should not have such issues.
