Red Hat Bugzilla – Bug 463118
Regression: X presents blank screen
Last modified: 2009-10-22 08:47:05 EDT
Description of problem:
X11 is broken for me on a PowerPC G4 iBook in recent versions of Rawhide. When I boot into X mode, my screen goes black. Switching to another (text) virtual console does not work -- i.e., the screen stays black. My graphics card is identified as an ATI Technologies Inc M9+ 5C63 [Radeon Mobility 9200 (AGP)] (rev 01). I have removed my xorg.conf, but things were working fine without it until the update.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Boot into X mode.
Blank screen, as noted above.
X should start.
The update that caused this regression happened sometime after bug #460721 was fixed.

Log of X starting -- result is blank screen, changing virtual terminals does not work
Same hardware (iBook G4/ati m9+ m5c63), same problem. However, I'm able to boot in runlevel 3 but the kernel drm/radeon driver is oopsing. So X won't start and I've the black screen in rc5. See the attached log.
Also, with those kernels, plymouth(?) displays some bright white kernel lines and then displays three mixed progress lines (blue, light blue and white) at the bottom of the screen with some more garbage. Sorry no camera but, thrust me, it doesn't look good.

In addition to my X problem, I see the same plymouth problems as Benjamin (comment #2). However, I would like to point out that I did at one point have X working even though plymouth didn't look quite right. So, these seem to be separate problems.
I had hoped that my problem was the same as the one in the thread at https://www.redhat.com/archives/fedora-devel-list/2008-October/msg00088.html. However, an update to the newest Rawhide (including a libdrm resync) did not seem to fix the problem.
I've the same issue since xorg-x11-drv-ati-6.9.0-25.fc10.i386. After graphical boot, the Monitor turns off.
Bad : xorg-x11-drv-ati-6.9.0-25.fc10.i386
Sorry forgot to say: Graphic Card is "ATI Radeon HD 3850 AGP".
xorg-x11-drv-ati-6.9.0-28.fc10.i386 is also broken!
xorg-x11-drv-ati-6.9.0-29.fc10.i386 is also broken.
I'va made a new bug-report for this bug, since it is not the same as in description:
I'm also seeing this (or at least these symptoms) on a similar machine to the submitter's. With the 184.108.40.206-97 kernel from F9, everything works.
I downgraded my kernel to 220.127.116.11-79.fc9.ppc and the problem is fixed. Reassigned bug to kernel.
The 18.104.22.168-94 f10 kernel also works for me. As far as I recall, 22.214.171.124-79 didn't.
Fixed in 126.96.36.199-94.fc10.ppc.
