Kernel config change to make MSI laptop touchpad work
Hello Debian Kernel Maintainers,
TL;DR: please enable CONFIG_PINCTRL_METEORLAKE=y in kernel config
I recently bought an MSI laptop, Micro-Star International Co., Ltd.
Prestige 16 AI Studio B1VEG/MS-15A2, BIOS E15A2IMS.10A 01/29/2024 which
uses Intel Meteor Lake Core Ultra CPU, which is fairly new.
I installed debian stable out of the box and a lot of hardware did not
work. A lot of this was resolved by installing upstream firmware but the
debian stable kernel is too old sadly. I upgraded to bookworm-backports
kernel-image (6.6.13) but was still stuck on 800x600 display, no
touchpad. I installed the kernel-image from SID (6.7.9-2) which resolved
the graphics issue but the touchpad was still not working.
I installed fedora 39 and the touchpad was working fine, so I compared
the kernel config between the 2 distros and after a little trial and
error found that:
CONFIG_PINCTRL_METEORLAKE=y
must be set in order for touchpad to work. Please consider enabling this
option in the debian kernel config as it may help others.
Thank you
