X is not wanting to die when closing out of fluxbox.

would it be possible to do emerge kernel 4.5.2 again because it was fine, if so not sure how i would do it.

 

ps before you go googling this error its well known that intel i915 is not so great, should of been clear on this.

i am wondering more about reverting back to 4.5.2 kernel with and emerge if that is even possible?

 

thanks

ok figured it out, simply emerge debian-sources-4.5.2 did the trick

as a bonus fixed my X problem.
