Bug Description

Debian has recently made a 1.1-1.2 release of libxcb to stable. Since Hardy derived from the same version and is LTS, I thought these changes might be worth also applying to Hardy.

The changelog for 1.1-1.2 reads:

libxcb (1.1-1.2) stable; urgency=low

  * Non-maintainer upload to fix important performance issues
    (closes: #487635).
  * Fix some fd leaks in _xcb_open_*()
  * Increase libxcb buffer size to 16k from 4k
  * Disable Nagle on TCP socket

If you do make an SRU containing these changes, please also ensure that the version in ia32-libs is updated.

Hi apollock,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

This bug was fixed in the package ia32-libs - 2.7ubuntu7

---------------
ia32-libs (2.7ubuntu7) karmic; urgency=low

  * Update sources.list.deb for karmic.
  * Revert gtk+2.0 change from 2.7ubuntu6, as the underlying bug was fixed
    in gtk+2.0 2.16.1-0ubuntu3.
  * fetch-and-build:
    - Add pulseaudio, since libpulsecore moved there.
    - Drop libcap1, which is now obsolete.
    - Replace libdirectfb-1.0-0 with libdirectfb-1.2-0.
    - Replace libkrb53 with libgssapi-krb5-2, libk5crypto3, libkrb5-3, and
      libkrb5support0.
    - Replace gcc-4.3-base with gcc-4.4-base.
    - Replace python2.5 with libpython2.6.
    - Replace libdb4.6 with libdb4.7.
    - Add libvorbisenc2 for libsndfile1/pulseaudio/pulseaudio-utils.
    - Add libv4l-0 for libsane (but just depend on lib32v4l-0 on amd64).
    - Add libudev0 for pulseaudio.
  * Depend on lib32asound2-plugins on amd64 instead of shipping it (LP:
    #305860).
  * Depend on lib32bz2-1.0 on amd64 instead of shipping it.
  * Freshen packages (LP: #277069, #389510, #393503).

Anyone who could test the packages in hardy-proposed?

We were only experiencing problems with the 32-bit version of the library on amd64 (via ia32-libs).

This proposed update has been in hardy-proposed for almost half a year without any positive feedback, and it was reported to cause a regression in bug 220628. Therefore it was removed from hardy-proposed again.
