Yes.  You can test what Xserver thinks about it with:
  Xomap -mouse tslib -nozap -wr -nolisten tcp -extension
XInputExtension

If you use something else, you can see what kind of an error
X server
would give (at startup) if the X server argument is not
correct.

Applications are run under "user" user, so it
cannot edit files that are
not writable by "user".
