Description of problem:
This is a fresh install of Fedora Core 9 on a Dell Optiplex 755. Graphical installation went fine, and boot time graphical mode shows fine too. When it comes time to switch into xorg, xorg crashes before displaying a desktop, catching sig 11. At that point monitor immediately reports system has gone into sleep mode (true whether analog or digital input selected).

Similar stuff here. Dell GX755 as well. I've seen a segv at some point as well,
however it's rather the first X server (for graphical boot) which leaves the
hardware in a bizarre state when it terminates. Later attempts to start again an
X server lead to segv sometimes.
The machines are in production use, so I can't give you more info ; my priority
was to get the machines back up and running. I'll give a try with the live CD
tomorrow, I noticed it did crash just the same way.
In the meantime, downgrading to F8 packages for the xorg server stuff did the trick.
After upgrading Fedora 9 packages, the Xorg.0.log file has new content. I'll
attach a new file in the next note, but in short, the last three different lines
+(WW) intel(0): PRB0_CTL (0x0001f001) indicates ring buffer enabled
+(WW) intel(0): PRB0_HEAD (0x00011234) and PRB0_TAIL (0x00011ec8) indicate ring
buffer not flushed
+(WW) intel(0): Existing errors found in hardware state.
The offer of remote access to this system and a network camera watching the
screen is still good; please see your email if you're interested.

Xorg log file after applying Fedora 9 patches
I disabled graphical boot (removed " rhgb quiet" from each of the kernel stanzas
in /boot/grub/grub.conf . With this change, the system comes completely up into
an Xorg login. This works after both a complete power off and a reboot.
At the moment, this appears to be resolved. I don't need a graphical boot for
Is there a chance that the graphical boot is not returning the video card to a
pristine state before X takes over?
