/var/log/messages snippet from booting.

There is a bit of funniness with the aperture hole at bootup.  It may be related (and perhaps even what tickles this bug).  The motherboard is an Asus m3a78t with integrated graphics and > 4gigs dram.

Comment 4 D. Hugh Redelmeier 2009-02-28 01:11:39 UTC
I too experience this problem.  See this thread: https://www.redhat.com/archives/fedora-list

Don't work:
 xorg-x11-server-Xorg.x86_64 0:1.5.3-13.fc10                                   
 xorg-x11-server-common.x86_64 0:1.5.3-13.fc10                                 

Work: 1.5.3-6.fc10 versions.

My system is an HP Pavilion A6245n
- C2Q6600 CPU
- 6G RAM
- Asus Asus EAH3650 Silent Magic video card
- Dell LCD (2560 x 1600 pixels)

All Fedora 10 updates are in place EXCEPT that I'm using xorg-x11-drv-ati-6.9.0-63.fc10.x86_64 due to https://bugzilla.redhat.com/show_bug.cgi?id=484636

There is some message that flashes when I boot (very early) that might be related to 4G and apertures.  It does not show up in dmesg output.  This is not new.

dmesg output isn't changed by the update.

When booting with the "bad" server packages, /var/log/message shows a lot of respawning of the X server.  There are a bunch of /var/log/Xorg.?.log files created.

Diffing Xorg.0.log files from bad and good runs, there are a couple of things I noted.

- Bad uses VT 7 whereas good uses VT 1.

-(II) RADEON(0): Using exact sizes for initial modes
-(EE) RADEON(0): Output DVI-0 enabled but has no modes
+(II) RADEON(0): Using fuzzy aspect match for initial modes
+(II) RADEON(0): Output DVI-0 using initial mode 2560x1600

This last difference seems to be the root of the problem.


If I had to guess which change caused the problem, I'd pick this one:

    * Mon Dec 22 2008 Adam Jackson <ajax> 1.5.3-8
    - xserver-1.5.3-aspect-me-harder.patch: Fix mode selection when only one
      monitor is present and it doesn't claim a preferred mode.
    - xserver-1.5.0-bad-fbdev-thats-mine.patch: Do the same for sbus that we
      do for pci.
    - xserver-1.5.0-hide-cursor.patch: Backport fixes to unhide logic from master.

Comment 7 Wolfgang Rupprecht 2009-02-28 01:26:02 UTC
I find it interesting that Hugh and I both have very similar 2560x1600 pixel monitors.  The modes these monitors present are somewhat unusual in that they are all marked as "Supported additional Video Mode". Might the lack of normal VESA modes be throwing the new mode-choosing code for a loop?

In #4 I had the wrong link to the thread.  Here is the right link.

Comment 10 seventhguardian 2009-10-16 08:09:56 UTC
Does this still happen with versions 1.6.* or 1.7.*?

Comment 11 Wolfgang Rupprecht 2009-10-16 08:17:38 UTC
No, I haven't seen this bug in many months.  In any case the current F11 version doesn't crash.

Comment 12 seventhguardian 2009-10-16 08:31:09 UTC
Then the bug should be closed, right?

Comment 13 Wolfgang Rupprecht 2009-10-16 08:35:45 UTC
Yes, feel free to close.  thanks!

Comment 14 seventhguardian 2009-10-16 08:45:08 UTC
Only the reporter and the admins can close it, that's why I asked you to do it ;)

Comment 15 Wolfgang Rupprecht 2009-10-16 11:27:21 UTC
I've never closed one before.  Someone else has always done it. 

The closest sounding choice to "fixed" seems to be "currentrelease".  Hope that is the right choice.
