I've installed XFree86 4.1 for the powerpc from xfree86.org, and am trying
to get X working again. I am using a Motorola Powerstack (prep) with the
clgenfb framebuffer, and linux 2.2.20pre6. The console works fine on the
framebuffer (I only have a framebuffer console in the kernel right now). I
have what almost seems to be a working XF86Config file, but when I start X
(using the startx script), it doesn't work completely. I get a blank
screen. However, when I look at the running processes, xinit. xclock, and
twm are running with my permissions, and X and 3 xterms are running with
root permissions (shouldn't the xterms be with my permissions too?). When I
quit X, the screen stays blank (though I do see a flicker), and I have to
reboot to get a display back. One thing that makes me curious is that the
shadow framebuffer is being loaded, and I don't specify it in the XF86Config
file. (And yes, it is using the config file I think it is using -- the
output from starting it verifies that). Another is that it indicates that
DPMS is enabled (could I be going into DPMS mode and not coming out of it?)
Does anyone have any suggestions, or alternate XF86Config files I could try?
I don't remember if I pulled the 2.4 clgen framebuffer code back into my 2.2
tree, but my tree is based on rsync from vger.samba.org/vger-2.2, so I could
pretty easily generate a diff on it (though if you'd like this, telling me
the command to generate the diff would save me the time from looking it up
:) ).
Thanks for any help.

I assume you are using the unaccelerated "fbdev" driver, which uses the
shadow framebuffer by default. To turn it off you must add:
Option "ShadowFB" "no"
As for DPMS, I doubt you are in a DPMS mode unless your dpms settings in
your XF86Config file are really off. The "fbdev" uses the console _blank
functions for DPMS.
Something to look into is that make sure you're using 8bpp in your
XF86Config and make sure clgenfb has a proper palette setup.
