PCs with hybrid graphics come with a two graphic card set-up. An integrated card for low power operations (like when running off battery, low 3D effects) and a dedicated card for more powerful applications. Windows manages both by keeping one off when not in use, and switching to it when needed. Not the case with Linux, when running linux both run at the same time draining battery, and making it over heat.
Thanks for the link, I'll try the VirtualBox set-up, hopefully I can contribute further to this.
