If you know your ThinkPad model does not 344 need to do NVRAM polling to support any of the hot keys you use, 345 unselecting this option will save about 1kB of memory. 346 347 ThinkPads T40 and newer, R52 and newer, and X31 and newer are 348 unlikely to need NVRAM polling in their latest BIOS versions. 349 350 NVRAM polling can detect at most the following keys: ThinkPad/Access 351 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute, 352 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12). 353 354 If you are not sure, say Y here.

It makes all 441 the extra buttons generate standard ACPI events that go through 442 /proc/acpi/events, and (on some models) adds support for changing the 443 display brightness and output, switching the LCD backlight on and off, 444 and most importantly, allows you to blink those fancy LEDs intended 445 for reporting mail and wireless status. 446 447 Note: display switching code is currently considered EXPERIMENTAL, 448 toying with these values may even lock your machine. 449 450 All settings are changed via /proc/acpi/asus directory entries.

This driver is required for access to controls not covered 488 by the general ACPI drivers, such as LCD brightness, video output, 489 etc. 490 491 This driver differs from the non-ACPI Toshiba laptop driver (located 492 under "Processor type and features") in several aspects. 493 Configuration is accessed by reading and writing text files in the 494 /proc tree instead of by program interface to /dev.
