Review on 🖥️ Vansungs 2 Port VGA KVM Switch with 3 USB Hubs: Share 1 Set of Monitor, Keyboard, Mouse, Printer, and U Disk between Two Computers (Includes 2 VGA USB Cables) by Adam Nelson

available I can confirm that VGA switching works fine for Windows 10 and Linux (Ubuntu 20.04). The button toggles monitor/computer combinations quickly, with no more than a blink delay, so it's great. However, I couldn't get USB switching to work for both, so be careful if you really want USB to work. Connect it to a USB hub that does not provide power. You must connect the USB port either directly to a computer or to an AC powered USB charger just for VGA switching to work. Initially I had an issue with VGA where the monitor flickered a lot, but it was a temporary power supply issue. The USB power cable was loose. The issue was resolved when the USB cable was plugged into the better port. Summary: VGA switching is good, USB switching is bad, at least for the Windows + Linux combo I'm using.
