To answer my own question: |
| 2 |
|
| 3 |
After a lot of diffing and searching, I was able to find out, that these |
| 4 |
were the modules that I was missing: |
| 5 |
|
| 6 |
CONFIG_TCG_TPM=y |
| 7 |
CONFIG_TCG_TIS=y |
| 8 |
CONFIG_HID_LENOVO=y |
| 9 |
CONFIG_THINKPAD_ACPI=y |
| 10 |
CONFIG_THINKPAD_ACPI_ALSA_SUPPORT=y |
| 11 |
CONFIG_THINKPAD_ACPI_VIDEO=y |
| 12 |
CONFIG_THINKPAD_ACPI_HOTKEY_POLL=y |
| 13 |
CONFIG_ACPI_WMI=y |
| 14 |
|
| 15 |
Without these modules, a X1 Carbon won't wake up from standby |
| 16 |
|
| 17 |
