Hello, I am using a Lenovo X240. Since upgrading to kernel 3.13 I've not been able to control my backlight and I get the following error message when the thinkpad_acpi module is loaded: thinkpad_acpi: Unsupported brightness interface, please contact ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx It worked perfectly fine in 3.12. Let me know if there's anything I need to give you to help resolve this issue. ------------------------------------------------------------------------------ Subversion Kills Productivity.
