Not only was I getting configuration issues (can't change hotkeys for, for example, fullscreen or mouse capture), it didn't allows 16:9 resolutions and, worse of all, had worse input lag than virtualbox. Interestingly, I saw this answer and tried out VMWare player for a debian guest, and found it to be a far worse experience.Update: I switched to VMWare Player because it's much faster (even with a single core I didn't notice any lag).

Right click the VM, Settings -> Display -> check the Enable 3D Acceleration tick box.

Give the VM more CPU cores to work with.Right click the VM icon, Settings -> System -> Motherboard tab, move the Base Memory slider bar to give the VM access to more of the host machine's memory. Give the VM more memory (RAM) to work with.Here are some things to try (all of these changes must be done when the VM is powered down):

For example, when I type something there is a noticeable delay before the words show up on the screen. I've installed a Ubuntu VM using VirtualBox, but when I start it up the input lag is really noticeable.
