Ubuntu 14.04 keyboard and mouse are unresponsive

Asked by sonoerin

I posted on askUbuntu.com but didn't get any help there. Thought perhaps going directly to the source would be more helpful.

I have seen many posts that didn't help me in my efforts to trouble shoot this issue. After a Ubuntu update and restart,my USB keyboard andUSB mouse are no longer responsive. I have tried the following steps from other posts to no avail:

 - sudo apt-get install --reinstall xserver-xorg-input-all
 - sudo apt-get install nvidia-current-updates
 - sudo apt-get --purge autoremove xserver-xorg-input-all && sudo apt-get install xserver-xorg-input-all
When I run uname -r I get: 3.13.0-55-generic if that helps.

I am able to use the keyboard during bootup and go into the bios, so the keyboard does appear to still be working.

Any ideas what caused this and how I can get my computer back?

Does the system have a make and model?
If you boot an older kernel is it OK?
What release of Ubuntu are you using?

I am using a Dell Inspiron with Ubuntu 14.04 and there is only the one version installed.

Only one kernel?

Hold SHIFT at boot and select an older kernel.

I get the same behavior with the current (3.13.0-55-generic) as well as the following:
3.13.0-49-generic

I jumped way down to 3.13.0-35-generic and was able to use my mouse & keyboard normally with this build.

I suggest you report a bug. State the version you can work with.

You cannot expect that the comands

 - sudo apt-get install --reinstall xserver-xorg-input-all
 - sudo apt-get install nvidia-current-updates
 - sudo apt-get --purge autoremove xserver-xorg-input-all && sudo apt-get install xserver-xorg-input-all

have any effect. The packages are just meta packages depending on the read driver packages and do not contain any software themselves.

The real driver packages are e.g.
xserver-xorg-input-kbd xserver-xorg-input-mouse xserver-xorg-input-wacom etc. etc.

Does disconnecting and reconnecting help? Does the command "lsusb" show the keyboard and mouse? Have you tried different USB ports? Is there any error message in dmesg or Xorg.log about keyboard or mouse problems?

Thank you Manfred,

Those install packages I tried were just some that I found when searching for solutions. I must confess that I don't know enough about Ubuntu to understand all the intricacies yet. Should I try to install the packages for xserver that you mentioned?

I did try moving the mouse and keyboard to various ports, but that didn't seem to help either. I looked thru the Xorg.log and didn't see any error messages for keyboard or mouse, just lots of lines about applying it as keyboard, etc.

When I run "lsusb" I get the following:
