Description:
Comet Lake CPUs can be paired with different PCH: the CMP platform is based on the 400-series chipset for Comet Lake processors, while the TGP platform is based on the 500-series chipset for Tiger Lake CPUs. However if a Comet Lake CPU is mounted on a TGP platform, i915 *fails* miserably to manage the video resulting in a blank, turned off, screen. Intel has provided a patch for this problem here: https://patchwork.freedesktop.org/patch/412664/ Additional info: * package version(s) Kernel: Linux 5.11.14-arch1-1 x86_64 CPU: Intel(R) Core(TM) i9-10900K (Comet Lake) MoBo: Asus Prime Z590-P * config and/or log files etc. This bug has been extensively documented on the linux Mint forum: https://forums.linuxmint.com/viewtopic.php?t=345452 |

Please see if that fixes the issue.
Or would you like me to build the kernel for you?
