I’ve had a system in the late 90s with a 3dfx voodoo card. Also had a laptop with a SIS card from the early 2000 era.
The voodoo card was THE card to have it it’s day (mine was an older second hand system though). The SIS card… for some reason they decided that standard VESA mode probing wasn’t a thing they supported and would hardware crash when that API was used. I eventually got it working in Linux after patching xfree86 to not attempt probing when loading the VESA driver.
I think I remember running into that as well but for whatever reason I couldn’t get accelerated-x working with the opengl libraries I was using for school. Likely the issue was just a lack of understanding on my part as I don’t think I had a good grasp of the Linux library loader until well after I graduated.
