Grrr...XF86 Problems
 

I accidentally screwed up my install of Debian PPC the other day, so today I decided to reinstall. Up until now, it's been smooth...

My problem is that I cannot start XFree86. I try to startx and I get the error :
Neither running xf86config nor dpkg-reconfigure xserver-xfree86 has been able to remedy this problem.

Any ideas? TIA.

Does ~/.xsession-errors or /var/log/XFree86.0.log provide any clues as to what is erroring out?
Post /etc/X11/XF86Config or XF86Config-4 depending on what you use.
Finally a guess, lower DefaultColorDepth to 16 if it's higher.

I tried lowering DefaultColorDepth to 16, and no luck.

I'll post my XF86Config file ASAP.

EDIT: And now, the error message has changed to no screens found!
Here's my XF86config file:

Like makuyl suggests, you should take a look at /var/log/XFree86.0.log and see all the lines that begin with (EE). One of these lines will tell you where the problem lies.

OK, I got the No Screens Found fixed, so it's back to AddScreen/ScreenInit failed for driver 0.

I dumped the log for XF86, and sure enough, I saw:
(EE) RADEON(0): FBIOPUT_VSCREENINFO: Invalid argument

So now I know what's going wrong; it's the only line that has the (EE). The question is, how do I fix it?

Have you tried with "vesa" driver instead of "r128"? You can worry about getting a better driver once you have at least x working.
Also try commenting out the first Device section with vga driver.

Just set it as a "Generic Monitor" let Debain pick it instead you tpying in "My Monitor"
