Can't adjust backlight by keyboard since kernel 3.14.x on my lenovo K29.
I was try recompile kernel 3.12, it work nice with "acpi_backlight=vendor" kernel commandline.
I was try this with same kernel config file:
gentoo-sources 3.12.x work
gentoo-sources 3.14.x NOT!!
gentoo-sources 3.17.x NOT!!
gentoo-sources 3.18.x NOT!!
kernel.org 3.14.4 work
kernel.org 3.14.6 work
kernel.org 3.14.20 work
kernel.org 3.14.30 work
kernel.org 3.14.39 work
Is the gentoo patchset make this problem?
Tell me if need some debug information.
