Why is the ‘Enhanced Session’ Option Grayed Out in Mint, and How Can I Increase Screen Resolution?

Hey! It’s true that 'enhanced session' is mainly for Windows VMs in Hyper-V, which explains why it’s grayed out for you in Mint. As for screen resolution, you might have better luck using the xrandr command in Terminal. First, check your current available resolutions by running `xrandr` without arguments, and if 2560x1440 isn’t listed, you can try adding it manually. Here’s a quick guide:

1. Create a new mode: `cvt 2560 1440 60` (or adjust the refresh rate if necessary)
2. Then, use the output from cvt to add a new mode: `xrandr --newmode `
3. Finally, add it to your display: `xrandr --addmode `
4. Set it: `xrandr --output --mode `

Replace ``, ``, and `` with the appropriate values you get from the commands. This should help you get your desired resolution! Good luck!

I can confirm that 'enhanced session' is indeed not applicable for Linux in most Hyper-V setups. If xrandr doesn't work out, another option is to consider installing the Linux Integration Services (LIS) for better graphics performance and more seamless integration with Hyper-V. Keep an eye on your graphics driver settings too; sometimes certain drivers have their own interfaces that might enable higher resolutions. If you're running Cinnamon, check the display settings there after any changes!
