Can confirm that sudo apt install linux-generic-hwe-20.04 makes everything work. Didn't have to remove OEM.
I've tried some earlier generic-kernels where the screen scaling (running 4k) would be off and the buttons for controlling the light (F5 F6) didn't work. But using the latest generic everything seems good. It is however the OEM which gets automatically installed during install and update and which breaks the system. So it really needs to be fixed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.10 in Ubuntu. https://bugs.launchpad.net/bugs/1940665 Title: Lenovo Carbon X1 9th gen no longer powers off Status in linux-oem-5.10 package in Ubuntu: Confirmed Bug description: Ubuntu 20.04.3 LTS linux-oem-5.10: 5.10.0-1044.46 Power off system, either through GUI or by shutdown -P now Expected result: System powers completely off What happens: System seems to be powering completely off.
