[Bug 1170885] Re: Samsung Laptop support module doesn't load for Samsung NP900X3C-A06AU
Another Laptop here (Samsung Ativ Book 7 - type: 730U3E-X04DE). It's not
on the list of hardware known to brick in UEFI mode. So I installed it
in UEFI mode. Samsung-laptop is not loaded here as well so some minimal
things are not working properly (keyboard illumination, fan-control,
WiFi switch).
I'd like to know if it's worth waiting for a reactivation of the kernel
module in UEFI mode or if I should switch my installation to BIOS (CSM)
mode.
Thanks for any information on this!

Title:
Samsung Laptop support module doesn't load for Samsung NP900X3C-A06AU
Status in “linux” package in Ubuntu:
Opinion
Bug description:
Similarly to Bug #1012284 "Samsung Laptop support module refuse to
load for Samsung 900X3C" I'm trying to load "samsung_laptop" in to the
kernel so that I can access functionality provided under
/sys/devices/platform/samsung (like keyboard backlight control).
When doing a modprobe I get "No such device":
# modprobe samsung-laptop
FATAL: Error inserting samsung_laptop (/lib/modules/3.5.0-27-generic/kernel/drivers/platform/x86/samsung-laptop.ko): No such device
I also tried a mainline build, as per https://wiki.ubuntu.com/KernelMainlineBuilds , and got the same result:
# modprobe samsung-laptop
FATAL: Error inserting samsung_laptop (/lib/modules/3.9.0-999-generic/kernel/drivers/platform/x86/samsung-laptop.ko): No such device
# uname -a

I'm not sure if this is a regression from the previous fix or simply
slightly different hardware.
