Title:
Display fails to correctly initialize if keyboard is not connected
during boot
Status in “xserver-xorg-input-evdev” package in Ubuntu:
Expired
Bug description:
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.
