touchpad-indicator crashes under Ubuntu MATE

[Ben Shadwick]

(created bug report for Rich's question because it affects me too -- Ben S.)

I've installed touchpad, but when I try to run it I get nothing but the mouse icon spinning for a few second then it quits.
Found the executable file for touchpad and ran it as sudo.

When I did I got an error message that showed the problem: "touchpad-indicator crashed with FileNotFoundError in open(): [Errno 2] No such file or directory: '/home/richard/.config/touchpad-indicator/touchpad-indicator.conf'"

It's true that the file is not there. I did a search to see if the file was anywhere, but could not find it anywhere on the machine.

Is there any advise you can give in order to get touchpad working on my machine?

Thanks,
Rich

If you need a copy of the crash report, I can send that to you. Let me know.

Update: It looks like someone knew this was an issue but commented the fix out for some reason. Here is a modification to /opt/extras.ubuntu.com/touchpad-indicator/share/touchpad-indicator/configurator.py that seems to get things working:

 def read(self):
# f=codecs.open(comun.CONFIG_FILE,'r','utf-8')
  try:
   f=codecs.open(comun.CONFIG_FILE,'r','utf-8')
  except IOError as e:
   print(e)
   self.save()
   f=codecs.open(comun.CONFIG_FILE,'r','utf-8')
  '''
  try:
   self.params = json.loads(f.read())
  except ValueError as e:
   print(e)
   self.save()
  '''
  self.params = json.loads(f.read())
  f.close()

Errno 2] No such file or directory: '/home/ben/.config/touchpad-indicator/touchpad-indicator.conf'

I have the same problem i create directory and file in my home folder
mkdir /home/marin/.config/touchpad-indicator
then
echo '{}' > /home/marin/.config/touchpad-indicator/touchpad-indicator.conf
then
sudo chmod 777 /home/marin/.config/touchpad-indicator/touchpad-indicator.conf
and all works

Ubuntu 15.04. :)

Thanks, both of you.

I really appreciate the resposes. I'll have to try them when I'm in my
notebook again.

Again,
Thanks!

The thing I can tell about this is that I managed to solve it by using your tips, but... the whole thing I made was just to:

Of course creating missing config folder and the file, and then:

(as @Marin Zapryanov suggested):
1.echo '{}' > /home/marin/.config/touchpad-indicator/touchpad-indicator.conf
2. sudo chmod 777 /home/marin/.config/touchpad-indicator/touchpad-indicator.conf

And that's all :)
Anyway thanks for suggestions.
I'm using Linux Mate 17.2 now, and as far as I can tell, Touchpad-Indicator installs it's files into /opt/ folder with "root" permissions. I changed them into my working user perms. I didn't change home config file permissions though, but I will test what kind of permissions it needs and then set it properly. I try to avoid using full 777 permissions on any files, even on my local PC/laptop.

Anyway, good to know this app works like a charm for me :)

It seems crashes only 1.0.5 version, I'm using older 1.0.4 version without problems :)
working touchpad-indicator 1.0.4 can be installed from official Ubuntu-derivative Baltix repository:
