No keyboard or mouse at 9.04 login screen

[mind0ne]

I upgraded to 9.04 from 8.10 last night from the update manager. After the update/upgrade completed, I restarted the computer as instructed. When it came to the login screen my keyboard and mouse did not respond. I have tried restarting and using the recovery console to start dbus and hal to no success. I turn the numlock on to see when the keyboard shuts off and it is after Ubuntu is loaded but before the login screen appears. The computer is not frozen so some how 9.04 is disabling my mouse and keyboard. I am using a standard ps/2 keyboard and a 7 button usb mouse.

Try Ctrl+Alt+F1

If it goes to console, the keyboard is active.

Ok, I tried that and nothing happens. The cursor is blinking ready for some input but I can not type. I can use the keyboard in Grub, and in recovery mode at the console. It seems to be disabling the keyboard after this. I have toggled the numlock key on while its loading and it comes on. But right at the end of the load, before the login screen appears, the numlock light turns off and the keyboard is then unusable.

Here is an update, I don't know if this will help. I started in recovery mode and dropped to shell. I then ran sudo /etc/init.d/dbus start and hal start. Then loaded ubuntu using startx. This allows ubuntu to load with needing a user and password. My mouse was still unresponsive and so was most of my keyboard. I have a "power", "sleep" and "wake" key at the top of my keyboard. When I press the power key it brings up the shutdown box. When I press sleep i get an error dialog box in the lower right hand corner. Other than that no other keys do anything. If I do not run the commands from shell before startx this does not happen.

Like I said, not sure if it matters but it is a difference.

Any help would be greatly appreciated.

I found the same problem this morning upgrading Kubuntu 8.10 to 9.04. PS/2 Keyboard and mouse work at CLI but just before the login screen loads the keyboard and mouse freeze tight.

I dont know if its related but I tried running apt-get update" and apparently it says it can not locate any of the servers it needs.

I have exactly the same problem. Mouse and keyboard freeze.

I'm having the same problem. After upgrading from 8.10 to 9.04, if I boot from my old (custom) kernel 2.6.27 the keyboard works until X starts, but at the login screen the keyboard and mouse don't work at all.

If I boot from the 2.6.28-11 generic kernel that was installed with 9.04, the keyboard and mouse work as expected.

I haven't been able to find the cause though.


UPDATE:

I was able to get the keyboard/mouse working on my old kernel by disabling HAL:
I added the following lines to my xorg.conf

Section "ServerFlags"
Option "AutoAddDevices" "False"
EndSection

and then uncommented the input device sections that were commented out by HAL.
# commented out by update-manager, HAL is now used
Section "InputDevice"

# generated from default
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/input/mice"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
EndSection

# commented out by update-manager, HAL is now used
Section "InputDevice"
# generated from default
Identifier "Keyboard0"
Driver "kbd"
EndSection

I still don't understand the cause of all this though.

Hello,

Same problem: No keyboard, no mouse at login screen. But, the keyboard works fine when using recovery mode, and both work well when using a live CD. So I guess no hardware issue is involved.

In recovery mode, I tried a dpkg-reconfigure xserver-xorg which worked fine, but nope. No keyboard, no mouse. The "try to repair..." menu item in recovery mode worked the same. Still no keyboard, no mouse.

The I tried a dpkg-reconfigure -phigh xserver-xorg. Here is the output:

Gtk-WARNING **: cannot open display:  at /usr/share/perl5/Debconf/FrontEnd/Gnome.pm line 54.
debconf: unable to initialize frontend: Gnome
debconf: (DISPLAY problem?)
debconf: falling back to frontend: Dialog
xserver-xorg postinst warning: overwriting possibly-customised configuration
   file; backup in /etc/X11/xorg.conf.20090521233742

What the... I tried a

• dpkg --configure debconf
• dpkg-reconfigure debconf
• dpkg-reconfigure -plow debconf (whatever means the "-plow")
• sudo /etc/init.d/hal restart

... but nope.

There are no broken dependencies on my system. I've xserver-xorg-input-mouse installed.

There are are a few posts about this on this forum, but none of help.

What if I apt-get remove xserver-xorg and apt-get install xserver-xorg ?

Any help appreciated.

Regards,

Marino
