Xorg.0.log from a successful boot
Description of problem:
At about the point in the boot sequence where I would expect the modeset switch to occur the screen goes black. The boot process doesn't complete. (Though I have encrypted partitions so I would need to be able to enter some data in order to finish the boot, so it's possible that the boot process is continuing, but that I can't tell.) When I use the nomodeset parameter the boot process works as expected.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot with modeset
I retested this with kernel 184.108.40.206-103.fc11.i686.PAE and I still get a black screen (with signal) early in the boot process if I boot with modeset instead of nomodeset.
Today I tried entering my luks password blind a couple of times and going away for 10 or 15 minutes to do some other stuff. When I came back I had a normal working gnome session. I tried switching to a vt and while a switch occured, the graphics in that mode were messed up. I had specs of white on a mostly dark screen. When I typed stuff, the specs changed. I switched back to X and my gnome session is working OK.
I currently have installed:
Thinking about it I thought it might also be useful to mention that I do not use the quiet or rhgb kernel parameters when booting. For testing I was using the 220.127.116.11-111.fc11.i686.PAE kernel with the following parameters:
elevator=deadline modeset crashkernel=256M

Xorg.0.log from modeset boot
I retested this with today's koji updates (xorg-x11-drv-ati-6.12.2-11.fc11, mesa-7.5-0.14.fc11 and kernel-PAE-18.104.22.168-128.fc11) and am still seeing the same symptoms.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
This is no longer happening in rawhide (F12).
