From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Desktop usage is almost always going to feel laggy in a VM because you don't have a real GPU inside the VM and it will fallback to some non-accelerated framebuffer mode. There are some GPU virtualization solutions, for example QEMU has
virglthat offers 3D acceleration, but in my experience it's buggy/not ready and doesn't offer near bare metal performance.The only way to get near bare metal graphical performance in a VM is by using PCI pass through of an entire GPU, but that requires an extra GPU, is non-trivial to setup and comes with a lot of caveats.
VM has an option to enable GPU acceleration iirc, would that solve it?
Probably not. There are no implementations that I'm aware of that work well on a Linux guest.
