From cold start, dropping into userconf to disable atabus, logging
in blind and typing 'startx'.
There's a flash of white at the right edge of the top 1/16 of the
The screen goes completely black for a few seconds, then displays an
in-sync pattern of hash like art-deco fabric--very purple. There's a
black band across the screen about 1/8 the way down about 3/8 screen
height. There's a rectangle of grey hash almost 1/4 screen high and
1/2 screen wide located 1/8 screen from the left.
So X doesn't get things right either? It should at the very least get
its hash pattern all over the screen, in the right colours, and you
have enough video memory to do 1024x768 in 24bit. Now we're officially
entering twilight zone territory.
The reason why I asked this is this - I suspect we're not initializing
enough of the drawing engine, and on other hardware this is no problem
because the firmware did it for us. I wanted to see if X initializes
it so machfb can work right after X exits.
Seriously, I've been using machfb ffor ages on various Sun and Apple
branded cards and onboard video chips and I've never seen anything
The X cursor never appears. The keyboard is unresponsive at this
point. I can log in via ssh and terminate X (had to use -9), but
nothing further can be done from the console.
Any chance to mail me the Xorg.0.log?
I guess next time I see a Rev. A or B iMac at the flea market I need
to get it. I even have a video memory module sitting around.
