 |
|
I finally decided to get on with putting a sensible operating system on my PowerMac G5 but hit on screen corruption. Initially, at the boot prompt, the screen is fine but after switching to what I suppose one could call Linux console mode (just bigger text), immediately before running the init.d scripts, the screen shows a lot of 'snow' and a few blizzards in fact, like an old TV set suffering from atmospherics. The display is reported as | lspci: | | 0000:f0:10.0 VGA compatible controller: ATI Technologies Inc RV350 AP [Radeon 9600] |
The original card developed a fault so this is (apparently) a generic replacement, not a genuine Apple part. I tried booting with G5 video=radeonfb and G5 video=atyfb but no difference. Yellow Dog Linux suffers from the same problem.
Any ideas ?

Booting with G5 text nofb or G5 nofb makes no difference.
Unrelated supplementary: is it alright to use a stage3-ppc64-ul32-20091028 with a portage with a later date ? That stage3 is the only one available for PPC.
