I have an Asus F2A85-M PRO with an AMD A6-6400K APU (integrated Radeon graphics device), so no legacy stuff. From `drivers/gpu/vga/Kconfig`: ``` config VGA_ARB bool "VGA Arbitration" if EXPERT default y depends on (PCI && !S390) help […] config VGA_ARB_MAX_GPUS int "Maximum number of GPUs" default 16 depends on VGA_ARB help […] config VGA_SWITCHEROO bool "Laptop Hybrid Graphics - GPU switching support" depends on X86 depends on ACPI depends on PCI depends on (FRAMEBUFFER_CONSOLE=n || FB=y) select VGA_ARB help […] ``` But in `make menuconfig` I am unable to unselect it. -*- VGA Arbitration and the help says: Symbol: VGA_ARB [=y] Type : bool Depends on: HAS_IOMEM [=y] && PCI [=y] && !S390 Visible if: HAS_IOMEM [=y] && PCI [=y] && !S390 && EXPERT [=n] Location: Main menu -> Device Drivers -> Graphics support Selected by [n]: - VGA_SWITCHEROO [=n] && HAS_IOMEM [=y] && X86 [=y] && ACPI [=y] && PCI [=y] && (!FRAMEBUFFER_CONSOLE [=y] || FB [=y]=y) So, VGA_SWITCHEROO is not set, and, therefore, as `Selected by [n]:` suggests, I thought I’d be able to deselect it. It’d be great if you could help me out. Kind regards, Paul
