I installed LM 21.3 Cinnamon about a month or so ago (on my ASUS gaming laptop) and had to update the kernal to the latest in oder to get my external monitor working on my Nvdia GeForce RTX 4070 graphics card. All good for a while.
Then I had to take my laptop to a local computer fix-it shop to take out my D: ssd drive (which was formatted for Windows OS) because LM could not mount or read it. The guy in the shop tried to mount and read it in a Mac and Windows machine, to no avail. He said that the hardware was probably faulty. I am suspicious because it was working perfectly in Windows, and all I changed was the C: ssd drive (reformatted it and installed LM).
Now I notice the LM "System Info" showing Graphics Card NVIDIA Corporation Device 2860 which I read as 2860 denoting a much older and slower GPU (I had basically bought the laptop for the GeForce RTX 4070 graphics card). Now, I am thinking did the guy in the shop take me for an old fool and swap out my GPU?
Could this be a Linux gliche, LM not reading my GPU properly. Is there a software way to get more info on what the insitu GPU actually is? Or do I need to take it back to the suppliers to get them to open up my laptop? I don't feel confident to go physically poking around in it myself.
