(Discuss in Talk:Intel graphics#TGL/RKL GuC Submission) Reason: Despite Intel's documentation, Tiger Lake and Rocket Lake GPUs may actually support enable_guc=3, and have a default of enable_guc=1. Also, check that you have not disabled Intel by using any modprobe blacklisting within /etc/modprobe.d/ or /usr/lib/modprobe.d/.Make sure you do not have nomodeset as a kernel parameter, since Intel requires kernel mode-setting.The Intel kernel module should load fine automatically on system boot. There have been couple reports where the whole graphics stack hard freezes when xf86-video-intel is installed, not even switching to a different virtual console works (by pressing Ctrl+Alt+F n), only killing the user processes with SysRq works.However, the modesetting driver can cause problems such as screen tearing and mouse jittering on XFCE, artifacts when switching virtual desktops in Chromium, and vsync jitter/video stutter in mpv. 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.
