To install X11 based desktop, you may want to install specific Xorg xf86 driver packages for your video card's chipset, as they may support specific features, effects and acceleration modes, and avoid error messages during X initialization. However, the most basic X features should work fine with just using the default kernel video-modesetting drivers.

$ apk search xf86-video

- For VirtualBox guests use xf86-video-vboxvideo. Refer VirtualBox guest additions
- For Hyper-V guests use xf86-video-fbdev. Refer Hyper-V guest services.
