Comment 1 for bug 532579

I've discovered this bug bites if a custom xorg.conf is used to set the monitor data-rates for displays that don't provide EDID/DDC data (see bug #288807 "[i815] Wrong resolution on Vaio PCG-SRX51, PCG-SRX41 and PCG-FX370 due to incorrect h/v rates ").

In this case the xorg.conf that works successfully for Karmic 9.10 with Xubuntu causes this bug with Lucid 10.04 Xubuntu. Without the custom xorg.conf the xserver will start but only with a lower resolution and using only a small part of the LCD area.

I've attached a tar.gz archive that contains the custom xorg.conf, the user .xsession-errors, and all the logs from /var/log/ captured after a clean boot. The /var/log/Xorg* and /var/log/gdm/* logs were deleted prior to restart so the logs contained in the archive relate to the current start only.
