Hello ,


this is a repost to  messages here please someone may help

http://debian-powerpc.debian.narkive.com/kr93F3ID/debian-8-on-late-2005-g5-graphics-issues

i was away sometime from Debian@PPC after having sold my PowerMacG5 with 
AGP -
got a Powermac G5 quad withGTX7800 and am very happpy with it .
today got installed Wheezy withouth problems,

everything run smooth from beginning, sound came back after short tweak,

but wanted to compile kodi right from start and run in issue with gcc+ 
compiler too low 4.6 > 4.7+ would have been needed ... so i decided to 
upgrade to jessie.

now i have this graphic glitch , and i cannot do anything , no login ,
no exiting,

so my question is how can i prevent when booting debian jessie to come 
to this "graphical glitch" so that i can install this 3.18.kernel from 
Mr. Peter Saisanas that i downloaded?


Thank you very much + sorry for the Newbie Interruption.


Cheers + Happy Good Night.

Rich
