Keyboard and touchpad not working

Thank you for taking your time to report this bug and help make Ubuntu better. Can you please check whether you can access the virtual consoles by pressing Ctrl+Alt+f[1]-f[6] keys? If so, this bug may be related to bug #271138.

Can you also attach the following as separate attachments to this bug report?

1. Xorg.log
2. lsusb -v
3. lspci -vvnn
4. strace when gdm hangs at the login screen, either using [1] or [2]

Thanks in advance.

Yes, I can access all the virtual consoles and login. However, restarting gdm doesn't solve the problem for me. I tried the following commands:

sudo /etc/init.d/gdm stop
startx

and

sudo killall gdm
sudo /etc/init.d/gdm start

lsusb -v

lspci -vvnn

Hi,

I am experiencing the same problem on a Advent 4211. After doing the partial distribution upgrade and restarting the keyboard & touchpad do not respond.

My first time trying out a Beta so just walk me through whatever information you require. There are a few other people on the Ubuntu forums talking about this.

I found a solution for the problem in duplicate bug #271138 :

sudo apt-get install xserver-xorg-input-all

Keyboard and touchpad is now working. I'm not sure what the cause of the problem was, but in my xorg.conf I found this:

(WW) Warning, couldn't open module evdev
(II) UnloadModule: "evdev"
(EE) Failed to load module "evdev" (module does not exist, 0)
(EE) No input driver matching `evdev'
(EE) config/hal: NewInputDeviceRequest failed
(II) config/hal: Adding input device AlpsPS/2 ALPS GlidePoint
(II) LoadModule: "evdev"

And when I installed the package above, apt-get printed: "Selecting previously deselected package xserver-xorg-input-evdev."
I'm not an expert on this, but it looks like "evdev" was simply missing... ?

As reinstalling xserver-xorg-input-all seems to fix the bug, am confirming this. Thanks for your information.

@KD, can you try the same work around of manually installing xserver-xorg-input-all and check whether it fixes your problem? Thanks in advance.

As the fix seems to be the same, this bug is similar to bug #271138 and am marking this as a duplicate of that bug. Please follow up the parent bug for improvements.
