Ok so I'm doing my first Gentoo install on the PPC architecture. I've done a few installs on x86 architecture before, but for all intents and purposes I'm a newb. After a lot of trial and error, I got a kernel configured and running after installing from a Stage 3 tarball. Next step for me is to get XFCE working. So I did:
Code:
emerge xfce4

That eventually worked, but when I tried to generate a xorg.conf, none of the suggested methods in The X Server Configuration HOWTO worked. I tried both
Code:
Xorg -configure

and
Code:
xorgconfig


In both those methods, all I got was a blank screen when I tried starting either xfce or using the startx command. Also, I couldn't exit, so I had to do a hard reboot. I tried to find some example xorg.conf files online to work from, but every one I tried gave me garbage on the screen (a working mouse though) and the same problem where I couldn't exit. Specifically, I tried most of the Powerbook examples at www.linux-laptops.net

I was wondering if someone could post an example xorg.conf for my computer setup here for me to work from? So far I have found none that are specifically 17" Powerbooks and none that match the output of my /proc/cpuinfo

I'll be back around later to post my current xorg.conf and output of /proc/cpuinfo (as well as any other info requested). If someone can give me a suggestion before then, it would be much appreciated :D

Edit: Here is my /proc/cpuinfo:
cat /proc/cpuinfo
processor: 0
cpu: 7447A, altivec supported
clock: 1499MHz

I've got the exact same laptop and have been able to successfully start Xorg. The configuration in the other post worked for me as well. The only problem that I'm running into now is that the refresh rate is down at 60Hz, which is just killer on the eyes. I think I just need to find the right mode for the fb.modes file since the Xorg configuration is using the framebuffer device, but haven't come across it yet. Anyone have any suggestions how to bump the refresh rate up?

Hmmm... I tried the xorg.conf from that other thread but it didn't seem to work. One thing I oughta mention is that whenever I activate DRI in the xorg.conf, instead of all that garbage on the screen I get a black screen. It seems like changing the HorizSync and VertRefresh rates in the xorg.conf changes the relative order of the garbage displayed onscreen, so I'm guessing that this is all I need to get right. However, I haven't been able to figure out what the right values are supposed to be, and I can't seem to find them when I boot up in OSX.

Ok so I had to put down Gentoo for a while as schoolwork called. I ended up reformatting my disk and repartitioning so that I can now dual boot Gentoo/OSX. Now I'm back to the exact point I was before, and I still can't get xorg working.

Here is the current copy of my xorg.conf:
http://sigmachi.yi.org/jims_bitchass_xorg

Here is the output to /var/log/Xorg.0.log:

Instead of the crap in the screenshot that someone posted from my computer earlier, I get a blank screen for a few seconds before x crashes out and dumps me back onto the command line.

I got it to work. All I did was generate an file with Xautoconfig and then I replaced the Horizsync and Vertrefresh values with the ones posted in the xorg.conf posted above.

What refresh rate are you getting? Could you post the config here?
