  292. Optionally, the driver will also allow software control (the
  293. ALSA mixer will be made read-write). Please refer to the driver
  294. documentation for details.

  320. Overriding LED state on ThinkPads can mask important
  321. firmware alerts (like critical battery condition), or misled
  322. the user into damaging the hardware (undocking or ejecting
  323. the bay while buses are still active), etc.
  324. LED control on the ThinkPad is write-only (with very few
  325. exceptions on very ancient models), which makes it
  326. impossible to know beforehand if important information will
  327. be lost when one changes LED state.
  328. Users that know what they are doing can enable this option
  329. and the driver will allow control of every LED, including
  330. the ones on the dock stations.
  331. Never enable this option on a distribution kernel.

  343. server running, phase of the moon, and the current mood of
  344. Schroedinger's cat. If you can use X.org's RandR to control
  345. your ThinkPad's video output ports instead of this feature,
  346. don't think twice: do it and say N here to save memory and avoid
  347. bad interactions with X.org.
  348. NOTE: access to this feature is limited to processes with the
  349. CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
  350. where it interacts badly with X.org.
  351. If you are not sure, say Y here but do try to check if you could
