[max <max@mntl.de>]

Source: linux
Version: 4.15.4-1
Severity: wishlist

Dear Maintainer,

the thinkpad X1 Carbon 2018 (Gen 6) needs following changes in the kernel config to make the touchpad and the trackpoint to work reliably:

    CONFIG_RMI4_CORE=m
-   # CONFIG_RMI4_I2C is not set
-   # CONFIG_RMI4_SPI is not set
-   # CONFIG_RMI4_SMB is not set
+   CONFIG_RMI4_I2C=m
+   CONFIG_RMI4_SPI=m
+   CONFIG_RMI4_SMB=m
    CONFIG_RMI4_F03=y
    CONFIG_RMI4_F03_SERIO=m
    CONFIG_RMI4_2D_SENSOR=y
    CONFIG_RMI4_F11=y
    CONFIG_RMI4_F12=y
    CONFIG_RMI4_F30=y
-   # CONFIG_RMI4_F34 is not set
-   # CONFIG_RMI4_F54 is not set
-   # CONFIG_RMI4_F55 is not set
+   CONFIG_RMI4_F34=y
+   CONFIG_RMI4_F54=y
+   CONFIG_RMI4_F55=y

(as well as the boot parameter psmouse.synaptics intertouch=1.)
