No screen after update

[arxontas]

Well i have tried everything .NO luck.
So i have re-install 3.4 two times.
3.4 has kernel 4.4.0-70
update  after install and got 4.4.0.85

After i play some, with some programs,i re-install to day again the 3.4  with 4.4.0.70 kernel BUT when i update  i got no 4.4.0.85  got 4.4.0.86
Really i do not know what is the best of those 3 kernels to use .
I like to know before i install the ham-radio ax25 and Jnos. Any ham-radio op here know anything abt?

Thanks
