If you can use X.org's RandR to control 301 your ThinkPad's video output ports instead of this feature, 302 don't think twice: do it and say N here to save some memory. 303 304 If you are not sure, say Y here. 305 306config THINKPAD_ACPI_HOTKEY_POLL 307 bool "Support NVRAM polling for hot keys" 308 depends on THINKPAD_ACPI 309 default y 310 ---help--- 311 Some thinkpad models benefit from NVRAM polling to detect a few of 312 the hot key press events. If you know your ThinkPad model does not 313 need to do NVRAM polling to support any of the hot keys you use, 314 unselecting this option will save about 1kB of memory. 315 316 ThinkPads T40 and newer, R52 and newer, and X31 and newer are 317 unlikely to need NVRAM polling in their latest BIOS versions. 318 319 NVRAM polling can detect at most the following keys: ThinkPad/Access 320 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute, 321 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12). 322 323 If you are not sure, say Y here.

As some of Medion laptops are made by ASUS, it may also 379 support some Medion laptops (such as 9675 for example). It makes all 380 the extra buttons generate standard ACPI events that go through 381 /proc/acpi/events, and (on some models) adds support for changing the 382 display brightness and output, switching the LCD backlight on and off, 383 and most importantly, allows you to blink those fancy LEDs intended 384 for reporting mail and wireless status. 385 386 Note: display switching code is currently considered EXPERIMENTAL, 387 toying with these values may even lock your machine. 388 389 All settings are changed via /proc/acpi/asus directory entries. Owner 390 and group for these entries can be set with asus_uid and asus_gid 391 parameters. 392 393 More information and a userspace daemon for handling the extra buttons 394 at <http://sourceforge.net/projects/acpi4asus/>. 395 396 If you have an ACPI-compatible ASUS laptop, say Y or M here. This 397 driver is still under development, so if your laptop is unsupported or 398 something works not quite as expected, please use the mailing list 399 available on the above page (acpi4asus-user@lists.sourceforge.net). 400 401 NOTE: This driver is deprecated and will probably be removed soon, 402 use asus-laptop instead. 403 404config ACPI_TOSHIBA 405 tristate "Toshiba Laptop Extras" 406 depends on ACPI 407 depends on INPUT 408 select INPUT_POLLDEV 409 select NET 410 select RFKILL 411 select BACKLIGHT_CLASS_DEVICE 412 ---help--- 413 This driver adds support for access to certain system settings 414 on "legacy free" Toshiba laptops. These laptops can be recognized by 415 their lack of a BIOS setup menu and APM support. 416 417 On these machines, all system configuration is handled through the 418 ACPI. This driver is required for access to controls not covered 419 by the general ACPI drivers, such as LCD brightness, video output, 420 etc. 421 422 This driver differs from the non-ACPI Toshiba laptop driver (located 423 under "Processor type and features") in several aspects. 424 Configuration is accessed by reading and writing text files in the 425 /proc tree instead of by program interface to /dev. Furthermore, no 426 power management functions are exposed, as those are handled by the 427 general ACPI drivers. 428 429 More information about this driver is available at 430 <http://memebeam.org/toys/ToshibaAcpiDriver>. 431 432 If you have a legacy free Toshiba laptop (such as the Libretto L1 433 series), say Y. 434endif # X86_PLATFORM_DEVICES 435
