Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!
** Description changed: Binary package hint: xorg Using a fresh daily build of Intrepid (tried both the live cd and an installation made with the alternate cd): Xorg fails when an external monitor is connected to my laptop (Dell Inspiron 6400, ATI X1400 graphics card) through a KVM switch. After a scrambled splash screen, the screen goes black. The problem does not to occur when the monitor is unplugged or connected to the laptop directly (instead of through the switch). It also works fine in Hardy. In case it is relevant, this is the KVM switch: http://www.equip-info.net/english/index.php?main=10&gruppe=300&prod=2188 The monitor is a Samsung SyncMaster 930BF.
