Title:
Samsung Laptop support module doesn't load
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

2013 x86_64 x86_64 x86_64 GNU/Linux
I'm not sure if this is a regression from the previous fix or simply
slightly different hardware.
