Dapper Flight CD 3: X server failed to start - Fatal server error: Active ring not flushed

[Petr Tomeš]

After successfull installation of Dapper Flight CD 3 on Pentium Celeron 500 Mhz X server failed to start and appeared text dialog about this error. Ubuntu 5.10, Ubuntu 5.04 and SUSE 10.0 haven't this error on this machine.

According to advice on https://wiki.ubuntu.com/DebuggingHardwareDetection and https://wiki.ubuntu.com/DebuggingXAutoconfiguration I will attach some outputs and files, which should help clearly identify a problem.

Forwarded to upstream: https://bugs.freedesktop.org/show_bug.cgi?id=5685

[John (john.e)]

Confirmed here,
solved by setting the correct setuid for Xorg.

[Baishampayan Ghose (b.ghose)]

Rejecting since it makes no sense.

[Baishampayan Ghose (b.ghose)]

Kindly test it with Dapper Flight 5 and reopen if it exists. Thanks a lot for the report :)

[Petr Tomeš (ptomes)]

Why it make no sense? This bug still exits, I can confirm it on Dapper Flight 4 and even on Dapper Flight 5. You didn't see remote bug watcher, where is link on this bug on upstream bugzilla.freedesktop.org, where this bug was reopened?

[Petr Tomeš (ptomes)]

Please see:
https://bugs.freedesktop.org//show_bug.cgi?id=5443#c56
https://bugs.freedesktop.org//show_bug.cgi?id=5443#c57

[sam tygier (samtygier)]

Petr could post the output of
ls -l /usr/bin/Xorg
to see if john's fix might work.

there is a patch on the upstream bug report https://bugs.freedesktop.org//show_bug.cgi?id=5443

[Petr Tomeš (ptomes)]

Sam, I will post output of "ls -l /usr/bin/Xorg" later today.

I download, burned and try to use following release on the same machine: http://cdimage.ubuntu.com/releases/dapper/flight-6/dapper-live-i386.iso

I tried to boot with defaults settings (I didn't change or set up anything), but after while I could see only text mode (not graphical version of booting process) which end at:

....
Generating locales
  en_USE.UTF-8... done
Generation complete
md5sum: /etc/X11/xorg.conf: No such file or directory

Ctrl+Alt+F2 didn't work and I could only press Ctrl+Alt+Delete to start reboot process. The same CD worked well on another computer. I don't know if it is related to this bug or if I have to open o new one.

[Petr Tomeš (ptomes)]

I download, burned and try to use the following release on the same machine: http://cdimage.ubuntu.com/kubuntu/releases/dapper/flight-6/dapper-live-i386.iso

X server didn't start but I pressed Ctrl+Alt+F2 and typed following:

ubuntu@ubuntu:~$ ls -l /usr/bin/Xorg
-rwxr-xr-x 1 root root 1565240 2006-03-23 11:42 /usr/bin/Xorg

I don't know if this can help to fix the bug and I don't know how I can set the correct setuid for Xorg.

[Adam Conrad (adconrad)]

Xorg isn't meant to be suid, only the wrapper (/usr/bin/X) should be.

[Petr Tomeš (ptomes)]

I haven't been doing something similar yet. So please what I should do? Could you please be a ready to provide some details to me?

[Alexandre Otto Strube (surak)]

Petr, is this bug still present for you with latest live builds? It's been quite some time since your last post.

[Petr Tomeš (ptomes)]

I can confirm this bug on Ubuntu 6.06 beta DesktopCD.

[Paul Sladen (sladen)]

So, AFICT the result of the upstream bugs is the suggestion to:

  "comment out ValidatePci() from xf86Bus.c"

but then the bug is dup'ed to:

  https://bugs.freedesktop.org//show_bug.cgi?id=6750

with a patch for handling Intel PCI-PCI bridges:

  https://bugs.freedesktop.org//attachment.cgi?id=5478

[Matt Zimmerman (mdz)]

Updated the bug watch to https://bugs.freedesktop.org//show_bug.cgi?id=6750

[Matt Zimmerman (mdz)]

The patch suggested upstream, with paths adapted for our source package. Can you build the xorg-server package with this patch and see if it fixes your problem?

[Petr Tomeš (ptomes)]

Very please fix this bug as soon as possible (ideally before release 6.06 LTS) otherwise I as one of Ubuntu Czech (http://www.ubuntu.cz/) leaders and coordinator of czech translations of Ubuntu will have only very limited opportunity to keepy my work on solid level (without using LiveCD/Desktop CD on other machine outside of my home) :(

[Paul Sladen (sladen)]

This should have been fixed with:

xorg-server (1:1.0.2-0ubuntu10) dapper; urgency=low

  * Backport a fix for Intel bridge handling:
  debian/patches/002_fix_for_certain_intel_chipsets.patch
  (Closes Ubuntu: #29880)

Petr: are you still seeing this problem with the latest dapper (Ubuntu 6.06?)

[Christian Holtje (docwhat)]

The latest update to dapper: works for me! Yay!
