Public bug reported: Binary package hint: xorg
Steps to reproduce: 1. Shut down the computer if running. 2. Disconnect USB keyboard connector (it does not matter if USB mouse is connected or not) 3. Boot Ubuntu 10.04 LTS Expected results: System boots up normally, one cannot login with GDM until a USB keyboard is connected (because password cannot be typed without a keyboard). Actual results: System boots up to black screen / invalid scan frequency / DPMS power off / disconnected DVI port (I don't know because I cannot diagnose the actual problem - at least my display goes to sleep and does not alert about invalid scan frequency). Hitting CTRL+ALT+F1 (or any other virtual console) does not end up getting the display up. I can still reboot the system with Alt+SysRq+B at will if I connect an USB keyboard.. Hardware: Motherboard: Intel DG45ID Display: HP ZR24w connected with a single link DVI connector running at 1920x1200@60 (correctly detected if booted with keyboard attached, uses KMS at least in normal boot process) Keyboard: Logitech "Deluxe 250" (basic 105 button USB keyboard) normally connected via HP ZR24w Mouse: Logitech RX 250 connected via HP ZR24w Note that the problem occurs only if boot without USB keyboard connected at all so the problem is not using the display as USB hub. Also note that this motherboard does not have any legacy connectors (IDE or PS/2) and I've tried with both USB legacy support enabled and disabled. I'd expect that the system could boot up without display, keyboard or mouse and any of those could be hot-plugged in. Perhaps I've misunderstood the currently supported features? The system had originally a CRT display connected via DVI-I/VGA adapter and has been upgraded to current display with DVI-D connection.
