I tried what they were talking about but could’t figure it out. I tried Mint and had the same issue, I reinstalled stock Ubuntu and it’s working again. The strange thing is that on Budgie and Mint it would show my second monitor, which was plugged into the gpu in display settings.
Also, i’m not sure who was downvoting you, but it wasn’t me.
Windows 10 has a bug with 100% disk utilization that goes away if you have an ssd. You should look into upgrading the ram to 4 or 8 gb. ddr3 ram is dirt cheap on ebay. It would probably cost $10-$15 for 8gb and another $10 for a 120gb ssd.
