Bug Description

I recently switched to the vesa driver instead of the intel driver and I
noticed that gnome-settings-daemon was not starting anymore. Further
investigation showed that it was segfaulting in the xrandr plugin. Removing
~/.config/monitors.xml fixes this. I already reported this bug in gnome bugzilla and it was suggested that this might be a problem with this patch: http://patches.ubuntu.com/by-release/extracted/ubuntu/g/gnome-desktop/1:2.25.3-0ubuntu1/100_load_desired_settings.patch

This bug was fixed in the package gnome-desktop - 1:2.25.5-0ubuntu1

---------------
gnome-desktop (1:2.25.5-0ubuntu1) jaunty; urgency=low

  * New upstream version:
    libgnome-desktop
    - GnomeBG: use gdk_color_equal() instead of custom function
    - GnomeRR: use XRRGetScreenResourcesCurrent instead of
      XRRGetScreenResources when available (xrandr 1.3) because it's cheaper
      (lp: #307306)
    - GnomeBG: emit "transitioned" signal instead of "changed" signal for
      new frames in a slideshow background
    - GnomeBG: reorganize code a bit
    - GnomeBG: add fading API to support fading between two backgrounds

gnome-desktop (1:2.25.3-0ubuntu2) jaunty; urgency=low

  * debian/patches/100_load_desired_settings.patch:
    - libgnome-desktop/gnome-rr-config.c:
      + clean up the patch to reuse code from the current API
      + don't segfault with old configuration files (LP: #314406)
      + remove notification on login when the configuration file
        is absent or invalid
      + don't let configurations_read_from_file() try to read xml
        files which don't exist

I am facing this problem for the past 3 days. I have a fully updated system, but there is no effect on the problem. How do I solve it? Should I completely remove the above mentioned packages and then install them again?
