Red Hat Bugzilla – Bug 339871
black screen with default configuration
Last modified: 2007-11-30 17:12:19 EST
Description of problem:
During fedora 7 installation, xorg is unable to work at all on a powerbook g4
titanium, 500 mhz powerpc. So i took fedora core 6, i installed with text mode
and upgraded to fedora 7. In order to launch X, I had to use fbdev driver.
Using r128 result in a complet black screen, even if X seems to be running, as i
can switch to a tty to disable it.
Every guide i have found on the internet speak of the r128 driver, so i guess
the autodetection is ok.
Version-Release number of selected component (if applicable):
every time, at least on this laptop
Steps to Reproduce:
1. install fedora 7

the log of x11 when i see a blackscreen
Try not using FBDev and use "ati" driver instead (although, it seems that you
are right and it should be r128). What are the results?
Actually, could you try even to run X without any /etc/X11/xorg.conf whatsoever?
It should work. If it doesn't than it is bug and we have to do something about it.
With ati, same problem.
And without config, X do not start, see the attached log file. I will try to
update to fedora 8 during the week.

xorg log without config file
I have updated to fedora 8, and I still see the same problem and same log file.
Have you tried to run Xorg without a config file? Any changes?
Laptop died 3 days ago, blackscreen on boot, so I guess i can close this bug as
NOTABUG, as no one confirmed the problem, so it may be a hardware problem :/
