I’ve seen that some people won’t be able to start Ubuntu Tweak 0.3.2. The condition may like this:
The splash screen is displayed and then nothing.
It’s not a common bug so I wrote this article to tell you how to fix this problem.
I saw your outputs, and there was nothing serious error message that cause the Ubuntu Tweak can’t start.
So I assume that the splash screen cause the problem, now I tell you how to disable the splash, I hope it’ll solve it.
First, open your terminal(gnome-terminal), and type the following command.
sudo gedit /usr/share/ubuntu-tweak/ubuntu-tweak.py
At the line 33, you’ll see “thread.start_new_thread(self.show_splash, ()) “, now you can put an “#” in font of line or delete this line.
So ubuntu-tweak.py will like this:
# thread.start_new_thread(self.show_splash, ())
from PackageWorker import update_apt_cache
Now save the file and try to start Ubuntu Tweak.
Please tell me the whether it is useful, thanks!
