To answer my own question: After a lot of diffing and searching, I was able to find out, that these were the modules that I was missing:
CONFIG_TCG_TPM=y CONFIG_TCG_TIS=y CONFIG_HID_LENOVO=y CONFIG_THINKPAD_ACPI=y CONFIG_THINKPAD_ACPI_ALSA_SUPPORT=y CONFIG_THINKPAD_ACPI_VIDEO=y CONFIG_THINKPAD_ACPI_HOTKEY_POLL=y CONFIG_ACPI_WMI=y Without these modules, a X1 Carbon won't wake up from standby Cheers Ralf On 08/25/2015 02:56 PM, Ralf wrote: > Hi folks, > > i just got my brand new Lenovo X1 Carbon and trying to get Gentoo > running on it. > > Beside some really big issues (HiDPI display, 2048x1152 resolution on > a 14" display really sucks on linux, xrandr scaling is horrible, no > scaling is damn too small to read, missing touch support in most > applications, ...)
