Are laptop GPUs different from data center GPUs? I would assume that Linux is so prevalent in DC that support for Linux would be a given.
You're right though, servers usually have some sort of very basic GPU for basic graphics. Sometimes from Matrox and others.
The parent comment makes no sense at all for a different reason. Intel wants to enter the top dGPU market and yes, Linux dominates the server landscape and yes, Intel probably wants to sell dGPUs to all the cloud providers and would have to continue to support Linux in that case.
Parent comment is simply FUD. It's sad it's been upvoted.
Many run completely headless and have no GPU at all, either on PCIe or in the processor.
