Thinkpad x230 display brightness

[Любомир Григоров]

Unfortunately, I knew that NVIDIA works. Different way the calls are made.
I had to go back to doing acpi_call and the VBRC to set brightness between
0-16. While not a button, it still works. I have yet to test
suspend/resume. Do you have USB powered after resume?
