Keyboard and USB mouse not working at login screen
1 Attachment(s)
I'm on a LG E500-VAP36P, with 3gb RAM, 250 Gb SATA HDD (Kubuntu Hardy kernel 2.6.27-9-generic), and my keyboard and my usb mouse don't work at the login screen. My touchpad works and my keyboard works in command-line session.

What can I do to solve this problem?

This is my xorg.conf. I also attach a relevant part of my syslog.

Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "pt"

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"

Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizEdgeScroll" "0"

Section "Device"
Identifier "ATI Mobility Radeon HD2600"
Driver "radeon"

Section "Monitor"
Identifier "Configured Monitor"

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Defaultdepth 24

Section "ServerLayout"
Identifier "Default Layout"
screen "Default Screen"
Inputdevice "Synaptics Touchpad"

Section "ServerFlags"

Did you try to remove the "ServerLayout" and "InputDevice" sections from your Xorg.conf? Xorg should automatically detect and use such devices.

If I remove that part I lose my touchpad as well.
Could it be a missing module?

Trying this I also notice that my NumLock light doesn't toggle when I press NumLock key - not sure if this was helpful

I guess I found an important part of the problem. Checking some logs I found this on Xorg.0.log:


(==) ModulePath set to "/usr/lib/xorg/modules"
(WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.
(WW) Disabling Mouse0
(WW) Disabling Keyboard0
(II) Loader magic: 0x3bc0
(II) Module ABI versions:
X.Org ANSI C Emulation: 0.4
X.Org Video Driver: 5.0
X.Org XInput driver : 4.0
X.Org Server Extension : 2.0
(II) Loader running on linux
(++) using VT number 7
It disables my mouse and keyboard! Why? How can I change this?

I just did a google search for "xorg AllowEmptyInput" and found on the Ubuntu forum that enabling the "evdev" module might solve this. It seems there is something wrong with HAL so Xorg needs its own drivers, but I'm not sure.

I added

Option "AllowEmptyInput""no"
to the ServerLayout section of my xorg.conf.

The keyboard now works, but when I logged in I got this message:

The following installation problem was detected while trying to start KDE:
No write access to '/home/namex/.ICEauthority'
KDE is unable to boot.
followed by another message:

Could not start kmserver. Check your installation.

Found a solution here.

And what about your mouse?
If it doesn't work, did you try the "evdev" module?

The "AllowEmptyInput" made xorg to disable my mouse and my keyboard. With this disabled, both work.
Now I have a dependencies problem to fix, nothing to do with this, however, just the remnants of a failed upgrade.
