install ibus select it and then see what happens to synapse after booting twice. make sure that synapse is set to autoboot
If thats all there is to it, I could do this in a 16.10 VM if it helps.
Edit
Installed ibus and autoboot and rebooted three times without issue, however I do see errors in 16.10.

So i installed zeitgeist
Did you select ibus in the language and support dialog box before rebooting. Then did you try to launch synapse. . However, I think you may need to change it to < ctrl + alt + space> or something else… like super key…
Synapse should have autostart selected in the preferences too. This will allow it to listen for the key sequence to launch itself.
Then when you launch synapse… you need to type something for it to crash. Perhaps I was not clear… If synapse is working you will see a list.
Follow the launching typing synapse steps 2 or three times. If you can confirm that 16.04 is ok with the updates given… that would be better, because I need this on a stable system. I only have 32 gb total on my sdd. and 17 are for windows which I almost never use, but sometimes for balabolka and maybe something else… not sure… maybe a cannon printer whent the need comes.
Hi,
I installed IBUS and set Synapse to auto start and I have no problems here, it does what it is supposed to do!.
Maybe you have some missing dependencies?, try the following terminal command which might help fix the problem:
sudo apt-get update && sudo apt-get dist-upgrade -f
Is that with 16.04 that you are talking about “no problems” or 16.10
DId you select it in the language support box?
I am talking about 16.04 
And yes!. I did select IBUS in the language box!. 
Is ibus selected in language and support box too? and then you rebooted? and tried ctrl space.
ok I will try right now… I just did an update too.
Yes it was all selected as you asked, I don’t see any problems here, did you try the command?.
I am still afraid… just rebooted… Just want to make sure… so there was no conflict with ctrl space or did you change the key to launch synapse?
I used Ctrl + Space and it worked fine!.
Well… I set my launcher of synapse as ctrl alt space and now synapse is dead again. I am not a happy camper. Perhaps I have some burmese installed. i do not know. I might guess this is not reproducible. Last I checked I could not fix this unless I reinstalled. I might try creating a new user, deleting my user, and then creating my old username back again.
did you type… I can launch synapse but if I type it does nothing. I set it back to ctrl space… still no hope. I have been down this route before
Maybe it has something to do with how you created your boot media?, did you follow this advice?:
You said this before… I downloaded an iso from the net. and installed via usb. no dvd rom on my laptop.
I did mention it but I just want to make sure that you fully formatted your USB stick before you created your USB stick!.
I usually do that, but I cannot confirm it. I think it would not matter. I am pretty sure I checked the md5 but I cannot confirm that. I am not sure why it would matter. can you install burmese just for kicks.
ok… I turned ibus back to none and then I rebooted and got synapse working. At least I can recover. Please install Burmese.
The good news was I reformatted windows and ubuntumate and made uefi boot. Grub is quite nice with the mategrub theme. grub theme is unuseable in legacy.
Er!, I don't think so as I have no idea about the language!, I just took a look at the IBUS page and found out you need another package for Burmese!:
sudo apt-get install ibus-m17n
so try that!.
