So im trying to repurpose an old late 2013 iMac (Core i5, 24GB of RAM, has the GTX 775M) 27" with Linux, because Apple wont be issuing security updates for it anymore.
Itll make a decent guest/browsing computer in the living room.
I put Ubuntu on it, which ive used casually for some time in a VM on my actual Mac (well, at least, before i recently got an M1 Mini), but ive never had any issues that required me to deep-dive into Linux-dom.
Even on the iMac, its working 95% fine - except the GPU drivers or something seem to be off.
Even on the VM i was using, the animations and window movement in the OS were always smooth.
On the iMac, everything runs fine and speedy (except Linux cant use the Fusion drive correctly, but whatever, dont care)... EXCEPT the animations, which are laggy and dragging windows around the OS looks choppy - rather like when you very first install WIndows and the GPU drivers aren't in yet so everything is choppy.
Its perfectly usable but i cant imagine that this issue cant be resolved, because it worked fine in a VM and was smooth, so im assuming there's just some driver issue (or lack of a driver issue, or whatever).
Anyone got any ideas?
