See, , Xorg#Installation, and modesetting(4). Some ( Debian & Ubuntu, Fedora, KDE) recommend not installing the xf86-video-intel driver, and instead falling back on the modesetting driver for Gen 4 and newer hardware.For 32-bit Vulkan support, install the lib32-vulkan-intel package. For Vulkan support ( Ivy Bridge and newer), install the vulkan-intel package.Beside this functionality, this package is generally not recommended, see note below. For the DDX driver which provides 2D acceleration in Xorg, install the xf86-video-intel package.For 32-bit application support, also install the lib32-mesa or lib32-mesa-amber package from the multilib repository.This driver has better performance and stability for Gen 7 and older hardware.
mesa-amber is the legacy Mesa package which includes the classic (non-Gallium3D) drivers for Gen 2 hardware and later.This is the recommended choice for Gen 8 and later hardware. mesa is the up-to-date Mesa package which includes the modern Gallium3D drivers for Intel's Gen 3 hardware and later.Install one of the following packages, which provide the DRI driver for 3D acceleration.See Xorg#Driver installation to identify your card.Intel's Gen N hardware does not refer to the generation of the CPU, it refers to the generation of the GPU, which is different from the generation of the CPU.PowerVR-based graphics ( GMA 3600 series) are not supported by open source drivers.Perhaps a less expensive version of Haswell like a Pentium or Celeron? If you have to order such online, the RMA of the 780ti may take less time, though. If you can get another CPU - beg or borrow (steal at your own risk) one to check it out. The sure way to tell where the fault lies is to swap parts. I have some delidded CPUs laying around with non-functional memory channels and PCIe lanes. That has the dual effect of risking this sort of failure and voiding the warranty. Heavy or off-center pressure from a cooler is one cause of socket pins missing the tabs on the CPU.Īnother possibility is a failed CPU. Use care to tighten the cooler evenly and not too tight. I suggest lifting the CPU, inspecting the socket for bent pins and reinstalling the CPU. Since the rig worked with the 780ti, most of the CPU is working. Digital outputs from the integrated graphics come directly from the CPU.
