[Bug 1001026] Re: special dell xps keys have scan codes already used by other keys

 

Same bug exists in Dell XPS L502X in Ubuntu 13.04 with the exact key
mappings as mentioned by Colin Walker. I'm afraid other XPS and Dell
laptops with touch buttons suffer from the same problem.

Waiting for a solution.

Title:
  special dell xps keys have scan codes already used by other keys

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Dell's XPS computers (mine is a L702x) have three touch sensative keys
  (I've included a picture) that aren't working properly. It seems that
  these keys have been given scan codes already claimed by other keys.

  Using showkey -s, I've found this:
  Key 1:   0xe0   0x5b   0x2d   0xad   0xe0   0xdb
  Key 2:   0xe0   0x4c   0xe0   0xcc
  Key 3:   0xe0   0x19   0xe0   0x99

  In windows these keys are used to reach settings, sound options, and
  an application of your choice. But in Ubuntu I can't give them a
  purpose because the above scan codes are already taken by other
  buttons as follows.

  Key 1:
  The "x" key has the scan code 0x2d 0xad
  The super key has the scan code 0xe0 0x5b 0xe0 0xdb
  which together match the Key 1 scan code

  Key 2:
  has a scan code identical to the brightnessdown key, which if fn + F4

  Key 3:
  has a scan code identical to the next track key, which is fn + F10

  So these three touch keys can't be used as intended (I've been trying
  to use them to launch important applications).

  Right now, they perform the same actions as the keys with matching
  scan codes. That is, Key 1 opens the launcher and occasionally types
  the letter "x", Key 2 lowers the brightness, and Key 3 skips tracks.
  I'd like to give these keys some useful function.

  Thanks a lot.
