After switching from Linux Ubuntu to Mint (Cinnamon) on my work laptop, I discovered that the Go to Definition functionality in Visual Studio Code, which uses Alt+Click, had stopped working.

This issue had been driving me crazy for weeks until I finally fixed it.

The problem was that Mint, by default, uses Alt+Click to move and resize windows, which was overriding and conflicting with VS Code’s Go to Definition functionality.

Solution

In Mint’s Windows Settings, change the “Special key to move and resize windows” from <Alt> to <Super>.
