Over the last week or more my rawhide AMD x86_64 system w/nvidia GeForce

a
login screen. If I use vesa driver, it also hangs, but shows weird lines
on
top and old startup text on bottom of screen. CTL-ALT-F2 gives a black
screen with no login prompt. I must do reset to restart machine. If I
use
the nouveau driver, X will start, but the screen is very dark. I am able
to
login to kde or gnome. I am at the 118 kernel. I think the last one
that
worked was in the 60's. Anybody have something to try? Any idea what is
broke?
Could you try the following kernel builds from koji and report:
http://koji.fedoraproject.org/koji/buildinfo?buildID=114132
http://koji.fedoraproject.org/koji/buildinfo?buildID=115527
http://koji.fedoraproject.org/koji/buildinfo?buildID=122803
Please install with:
# rpm -i --oldpackage kernel-$version.rpm
Best wishes,

I am sorry this took me so long, I just needed to make some time to do it.
I downloaded the suggested kernels (67, 86, and 101) and tried to boot each
one using the nouveau driver in xorg.conf. I did not try the nv or vesa
drivers. Let me know if you want these tested also. The kernel line in
grub.conf had rhgb and quiet parameters on all tests. I had a few other
kernels still installed, so I added them to the test. Tests were with
20090728 nouveau driver. Here are the results:
Kernel X-start? KDE Login F2 Console
* 67 No - Yes (large test)
* 86 No - Yes (small text)
94 No - Yes (small text)
*101 Yes Dim Yes (small text)
103 Yes Dim Yes (small text)
118 Yes Dim Yes (small text)
122 Yes Dim Yes (small text)
It seems the last working kernel for me was before 67. Maybe 64?
I did some more testing and noticed I was running with "DefaultDepth 16"
set in the xorg.conf file. I changed this to "DefaultDepth 24" and I not
get the normal bright login screen. It seems someone, somewhere has assumed
a 24 bit color depth when they should be testing for 16 (maybe even 8 or
15). I retested and 67, 86, and 94 still do allow X to start. Kernels 101,
103, 118, and 122 are now at full brightness. So something was changed
before kerenel 101 that ignores the DefaultDepth parameter.
Hope this helps.
Jim
