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

First I tried VNC. Easy install through Ubuntu GUI, but I could only see a still picture of the Ubuntu-desktop that wouldn't update. I could see on the Ubuntu monitor that the cursor was moving and the keyboard did work, but on my Windows computer, the screen didn't refresh. Then I read a bit on the forums and people seemed content with nomachine NX or freenx. After a bit of hazzle I finally managed to get a connection between my Windows and Ubuntu-machine. But the same thing happened here. I get to see a still picture of the Ubuntu desktop, mouse and keyboard working, but the screen doesn't refresh..!

I remember that in previous Ubuntu releases, it was possible to restart/shutdown at the logon screen via the keyboard. I think it was via the F10 key. Can this function be brought back?

Running Landmarq Intel Atom DC330 Desktop I have just attempted to upgrade my desktop machine from Kubuntu 10.04 to Kubuntu 10.10. I used KpackageKit to do the upgrade which proceeded smoothly until the install packages phase, which seemed to complete and then repeat. I don't know the detail of what happened as I was out of the room.
The repeat almost completed, but then I got a set of error messages, which basically told me that KpackageKit was unable to install the upgraded packages. I closed KpackageKit, and closed the machine and tried a reboot. This time, I got as far as the splash screen, but although the cursor flashes, I can't type anything in the password box. In addition, the mouse pointer won't move. Using a different wireless mouse works, but I still can't type in a password.
However, the command ctrl+alt+sysrq+RSEIUB works, so the machine is accepting some keyboard input. I also know from using a live disc that my home directory is intact. I would like to revert to my 10.04 installation, and re-try an upgrade to 10.11 afterwards.

I have updated my 11.3x64 recently and after updateI cannot log into any X session.Keyboard is dead but mouse is moving fine.I tried to change kdm to gdm - no result!All I can do now is - select by mouse "Console Session"and log in to common terminal. In terminal session keyboard works.I can't understand What is it?The most interesting:If I run terminal as a root and run startx - kde desktop is started but the same way - without keyboard!Hardware manager (YAST) shows: /dev/input/event0and shows type of keyboard right: AT Keyboard bla-bla-bla. (Common Genius PS/2 keyboard for 6$ :-))I suspect something wrong with my X11 but can't get what!I did not find xorg.conf in it's standard place. I have found only /etc/X11/xorg.conf.install

So my computer was slow with Karmic Koala, so I tried upgrading my build to Lucid Lynx 10.04.
Now I can't login because neither my keyboard nor mouse (and touch-pad) work. However, I can access the command mode (terminal?) though through the grub boot menu.
how I can get my mouse (and touch-pad) and keyboard to work with Ubuntu 10.04? My machine is an Acer Aspire 4730Z. I dual boot with Windows 7, and I'd prefer not to have to clear out the partition for Linux and reinstall.

I messed up my xorg.conf and tried to put in a clean one, but it doesn't seem to work. I'm not sure what went wrong. When X loads, the mouse cursor is not responding and my keyboard is dead too. I can't toggle to text mode either (Alt-Ctrl-F1).Hope the following files might explain what's wrong./var/log/Xorg.0.log
Code:
[ 26.835] (II) config/udev: Adding input device Power Button (/dev/input/event2)
[ 26.840] (II) No input driver/identifier specified (ignoring)
[code]....

I cannot use several keys (1,`, q, a, z & Esc) on my keyboard.I have just installed Kubuntu 11.04, AMD64 version via Wubi. Everything went well w/o any errors. At 1st boot, I also logged in w/o errors, and then tried some apps for Office & Network and shut down. The keyboard was still alright at that time. However, The problem started on the 2nd boot after the installation. Those keys do not response in Kubuntu & Windows 7 login screen and even in my PC's BIOS setup.
My laptop model is Dell Lattitude E6410, core i5, Intel HD Graphics, WD HDD 160GB. And I installed on the other partition, not my Windows one.

I just installed Ubuntu 9.10 on a dell d630 laptop and tried to connect an external ps2 keyboard and mouse using USB connectors to the laptop's USB ports. However, they are not detected by the system.

I was having a problem with the mouse and keyboard randomly failing to work after upgrading to version 10.04. I tried both the 32 and 64 bit versions. The problem went away after I edited the file /etc/default/grub and changed the following line:
from
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic nolapic"
If you are unable to open a terminal window, try doing the following
Ctrl+Alt+F1
Log into you account.
sudo nano /etc/default/grub
After saving your changes and exiting nano you can reboot by using the halt command.(FYI Ctrl+Alt+F7 gets you back into X server -- but you need to reboot for the change to take effect) Update: problem recurred. I had to do Ctrl+Alt+F1 to log into a console. I executed 'ps aux | more' to find the PID for X.Using the PID I restart X with 'sudo kill -S SIGTERM <PID>'.Once it started up again it was fine.

Looking to buy a wireless mouse/keyboard for my wife. Want one of good quality that will work with Ubuntu 10.04 and is in current production. Even better if its a brand that Fry's or Newegg carries.

I have an Acer 5102 WLMi laptop from 2005 with Ubuntu 9.10 installed. It has worked fine for years but now when I boot up my mouse and keyboard don't respond leaving me stuck at the login screen. I have tried using a USB mouse without sucess. My USB-powered cooling fan still works in all three USB ports fine. I have tried booting into the LiveCD and got the same results except for the CD auto-logging in. Eht0 still auto-connects to the network fine in the LiveCD. I can't find any wrong except for the keyboard and mouse not responding. My next step is to burn a LiveCD with start-up scripts to enable ssh. Also the touch-pad doesn't respond either

I am running 8.10 64 bit on my laptop and when making a new user I noticed that on my shell prompt, it said "I have no name!". It was bugging me so I logged out and went to log back in. I got some error saying I was logged in for less than 10 seconds after trying a couple times to login. So I restarted and now my mouse and keyboard don't work!

I have a laptop. . .Dell 1150. Ubuntu installed, bluetooth device installed and my bluetooth keyboard and mouse works like a charm. I decided to load up my same exact Ibuntu on my desktop, use the same keyboard on it, and the mouse too. I tested it on the laptop, just in case it would not work in Ibuntu, and I didn't want to wipe out my Windows XP on my desktop and find out Ibuntu would not work on it with a wireless keyboard. Since it worked very well with my laptop, I figured it would work just as good with my desktop. I wiped my desktop out, and installed Ibuntu. Everything worked fantastic. Until I tried to install the bluetooth.
When I plug in my Bluetooth device, Ibuntu finds it and asks to set up your device. I attempt to set up my keyboard/mouse combo and it asks for a 6 digit code (like it is supposed to). I enter the code and press enter. From here, the problem starts. Ubuntu "claims" to connect to the keyboard, shows it connected, but my keyboard does not work at all. Neither does the mouse that is built into the keyboard. I type and nothing happens. This also brings up (sometimes) another message that says my keyboard is trying to connect to the bluetooth device please enter keyboard PIN. Well.
I can't enter anything, because the keyboard does not work! The mouse does not work! I can (without any problems) disconnect and connect to my laptop, but I can't do this to my desktop. Both are dell units. Desktop is about 3 years old, laptop is about 8 years old. Both running Ubuntu, the latest version. Both recognize the bluetooth transceiver. I have tried different USB ports on the desktop with no avail. I would really like to use my desktop as a unit to my TV with a wireless keyboard, not my laptop. It is much faster, more memory, and I can use the TV as a monitor.

I have a Logitech Wave keyboard and mouse for my computer. I am not sure which version of Ubuntu I am running on but I think it is 6.10. When I boot up my computer I can go into the BIOS and earlier today it would even let me press escape to seee which operating systems I could boot. Now it no longer lets me see the operating system I have (which is why I cant say which version of Ubuntu I have). It takes me to the log in page and asks for the username and password but I cant type and I cant move the mouse. Earlier I could also use Alt+F1-F12, but this is no longer working either so it just sits at the login page and nothing works at all. The computer that is having this problem is very old it is a Proteva and when I opened up the actual computer the processor says:
At startup the computer says that the processor is a: AMD K-6
I know that the BIO's are to old for Ubuntu to run properly because at startup it also says that: "ACPI :
BIOS age (1998 ) fails cutoff (2000), acpi=force is required to enable ACPI" it also says that: "ACPI : unable to load the System Description Tables."
I have'nt used this computer for about a year or two, but the last time I used it it worked perfectly fine. I have been seeing questions on the forums similar to mine, but their problems are on other versions of Ubuntu and their mouse's are said to work fine. I cant try any of the solutions for the problems I have read about because I cant open the prompt that you get when you are at the log in screen and press F2. I have no idea what to do.

As the title says i have this error on both my main computer and my laptop. For my main computer see this post, that is when it happened. viewtopic.php?f=30&t=65743
I run the updates on my laptop a while ago and decided to restart it to check if everything went okay. It seems not.
The only way i can get on the desktop, is to choose the recovery mode, su to user and startx.
This is a common error during booting on both computers. Starting the hotplug events dispatcher: udevderror binding control socket, seems udevd is already running
It seems a little strange, same error on both computers.

System was running fine under 8.04 but decided to update. The live CD works fine but after install, the Mouse and Keyboard stop working under 9.10. Even the keyboard power button is off. Disconnecting and reconnecting the keyboard or the mouse does not . AMD Athlon 64 X2 3800+ PS/2 Keyboard and PS/2 mouse
Everything else seems OK but how would I know without the keyboard or mouse. The keyboard turns off right before the first Ubuntu screen. The Numlock will go off and then nothing. Tried to run dpkg - fix broken packages after booting to repair. All I get is fail to fetch http: (whatever )Could not resolve us.archive.ubuntu.com. Update: Alt-F3 ... then Booting to terminal mode does not disable the keyboard.

After I updated to 10.10, my ps/2 keyboard and mouse stopped working when in the gnome environment.I have tried to solve this by following the instructions here:
http://ubuntuforums.org/showthread.p...mouse+-working
. . . and by turning off usb legacy in the bios
. . . and by running these commands:
Code:
sudo update-rc.d -f gdm remove
sudo update-rc.d gdm defaults 25[code]..But nothing has worked so far.

I upgraded to 10.10 from 10.04 few weeks ago. Everything was working fine until today when I did a partial upgrade and it removed some of the lib files. Now my usb mouse and keyboard is not working. I can move the mouse around but can't click ( left or right ). I have nvidia graphics card. I tried running it under safe graphics mode and when I do that everything works fine except for the compiz obviously. I have tried reinstalling nvidia driver to see if that would make a difference but that didn't work either. I am not sure which lib files did ubuntu removed. I have searched everywhere to find a solution on the web and the only thing I think it might b iz my xconf file iz messed up. I really don't want to reinstall the whole OS and loose all my apps.

whenever I try to hibernate/sleep my computer and I come out of the sleep, the keyboard is not recognized and stops working altogether and requires a reboot. Changing the USB port does nothing either.

I've paired a bluetooth keyboard and mouse with my machine using the Gnome bluetooth wizard and the keyboard and mouse work fine. Then, if I let the computer sit for a few hours and then try to use the keyboard or mouse, nothing happens. When paired with my windows machine, and I start using the keyboard and mouse after a hour or two, the keyboard takes a second or two to start working again. I suspect that it turns itself off, and then has to reconnect, and that in Linux, the reconnection isn't working properly. I've found other instances on the forums of people with the same symptoms, but never any clear answers. Does anyone know what's going on?

I downloaded and burnt the Kubuntu 10.04 release to a CD. I tried to install it. First time, couldn't find the disks and eventually it froze. Ok, second try, when it's contacting the "time server" (or whatever) another freeze, but this time I notice everything is running fine and then get a nice little image with the current time (increasing seconds and all). Third attemp, clicked the "update this installer" and it went fine. "Yay!" I thought. Well, a few minutes in my beautiful 10.04 system and again, another freeze. Hit the power button and to my surprise a "Shutdown" dialog shows up with a countdown. After 30 seconds it logs out and mouse is working again. I log back in and come here to write this long post, and as I was writing the title "Random mouse/ke..." guess what? Yeah, it froze again. And the little bar that goes after the writing continued happily blinking. Hit the power button but this time mouse and keyboard were still frozen in the login screen.
Short version: mouse and keyboard randomly freeze while the rest of the system apparently work fine.
