walter -- i didn't think of this when we were designing all of
this: how about if, in addition to this patch, you checked at sugar
startup time and used the presence of that file in $HOME as an
indication that you should set ptmode for the user? then i could
eliminate a chunk of the code from olpc-utils that sascha was
btw -- i just looked at your patch again -- what happens if
NODE_PATH can't be opened for writing? write_touchpad_mode()
should fail gracefully in that case. making the node writeable
is the one line of code that will need to remain external to
sugar, and we shouldn't assume that it has happened. i'm
referring to this:
+ """ Write the touchpad mode to the node path and set/unset the flag. """
+ touchpad_mode_index = TOUCHPAD_MODES.index(touchpad)
+ node_file_handle = open(NODE_PATH, 'w')
+ if touchpad_mode_index == 0:
+ if os.path.exists(FLAG_PATH):
+ flag_file_handle = open(FLAG_PATH, 'w')
