Created attachment 285189 [details] Add vga_switcheroo option You might know that there are laptops with more than one video adapter. People use vga_switcheroo to disable one of those adapters to conserve battery power. It's a good idea to switch adapters as early as possible. Initramfs seems to be a good place to do this. With attached patch it is possible to use, for example, "vga_switcheroo=IGD,OFF" to switch to integrated videocard and disable another one.
