I just reinstalled Mate.
Before I did anything. I played with the language support.
Where it says “Input method” I moved it to the only choice it had (it was previously blank) maybe that was called auto or none… I cannot remember.
That messed up synapse the next time I logged in (maybe second boot).
Then I reinstalled again, knowing to stay clear away from that screen. I will use a libreoffice writer macro to make my language support.
I do not want to do this all over again. Once you use synapse, you cannot go back.
This is a heavy bug for me. and this happened on a fresh install, changing only that feature. (after setting synapse to autostart in the synapse preferrences).
Hopefully you can test this and let me know. I am in school and cannot do this again. I lost lots of mb on my data plan to reinstall.
