[Bug 1039261] Re: Xinput extension is too old

[Chris Samuel]

Looking at the diff between libXi 1.6.0 (used in 12.04) and libXi 1.6.1
(used in 12.10) shows this in the notes:

+   Consecutive calls to XIQueryVersion by the same client always return the
+   first returned major.minor version. If the client requests a version
+   lower than the first returned major.minor version in a subsequent call, a
+   BadValue error occurs.

Looking deeper at the xtrace I captured before this looks to be exactly
what is happening:

000:<:0096:  8: XInputExtension-Request(131,47): XIQueryVersion major=2 minor=1
000:>:0096:32: Reply to XIQueryVersion: major=2 minor=1
[...]

000:<:0100:  8: XInputExtension-Request(131,47): XIQueryVersion major=2 minor=0
000:>:0100:Error 2=Value: major=131, minor=47, bad=2
X Error: BadValue (integer parameter out of range for operation) 2
  Extension:    131 (XInputExtension)
  Minor opcode: 47 ()
  Resource id:  0x2
