Ubuntu :: Mouse And Keyboard Stop Working When X Server Starts?
Aug 28, 2009
I randomly started up my laptop one day and the mouse and keyboard stopped responding once GDM's login screen came up. Everything works fine from the console, but even if I run startx from the login shell the mouse and keyboard do not work, even though everything else in GNOME runs perfectly.
I am using an HP dv6426us laptop running Ubuntu 9.04 (i686 architecture with the 2.6.28-15-generic kernel). Below is a copy of my xorg.conf file, just in case there might be something wrong with that. I will try and put more information on, but seeing as I have to use a different computer to post this thread, copying over log files and stuff is difficult for the moment (though I am going to try and copy them over to a flash drive).
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.
I recently upgraded my Dell Vostro V13 from 9.04 to 10.04. All seemed to go well, but now the keyboard (and touchpad) aren't being recognized on bootup. I can get to single user mode OK --- keyboard is fine, but something is badly amiss as I can't use the mouse or keyboard when the X-server starts.
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.
I just install CentOS 5.6 on my computer. My mouse and keyboard stops working in 2 cases: 1. copy files from usb (FAT and NTFS); 2. update my system (specifically, when downloading update packages). But the system's still working. It seems weird but I can do nothing but reboot every time.
I'm running Fedora 12 on a Shuttle SN78SH7. Updates are all current from the Fedora repositories. I'm using the Nouveau driver for the Shuttle's on-board Nvidia graphics adapter. At random intervals (1 to 5 times per day), my USB keyboard and the buttons on my USB mouse stop working and the desktop freezes (i.e. GKrellm graphical data stops updating, partially painted windows don't complete). However, I can still move the mouse pointer around the desktop. This only seems to happen when I am actually using the computer from the console. It has never happened while the system was turned on, but not being used.
When the mouse and keyboard stop working, I can log in from another computer via ssh. Once the computer gets in this state, the only way to fix things is either to reboot remotely using ssh or to cycle power. I've run low level hardware diagnostics - everything checks out OK. This computer only has USB and firewire inputs. No PS2 jacks.
Keyboard and sometimes mouse stops functioning whilst using oowriter - it only happens with writer. I lose control for up to 30 secs and then it comes back - but it keeps happening. This is on a 10.10 machine with standard install. I have changed keyboard from wireless to wired and back to wireless with new batteries. I have uninstalled Office, rebooted and re-installed but it is still happening on native odt docs. Is this a common recent issue?
I have installed Ubuntu 10.10 on other machines before and have not experienced this problem. Occasionally, the system will lock up. They keyboard and mouse stop responding (my keyboard status lights no longer respond, but my optical mouse light is still on). I can ssh to the machine, and it seems to work as normal. I kill processes that are open on my desktop through ssh, (i.e., Firefox), and I notice when I switch back, I still have the same frozen image on my screen. I have looked at the following files to determine any issues with the GPU:
Hey folks. I'm not sure how to describe this properly but periodically Kubuntu 11.04 will stop responding to my mouse and keyboard EXCEPT that Plasma, or what I assume is Plasma, still responds to mouse events. I can launch and exit the desktop cube and desktop grid but can't access my panels or any application controls. The only fix I've found is to do a hard power cycle.
Does this behavior ring any bells for anyone? This is the last hurdle I've got between me and using Kubuntu 11.04 full time on my Samsung RV515.
My ubuntu session will freeze and stop working. For example, the mouse and the keyboard will stop responding and the screen sometimes get divided into 4 smaller quadrants of the current screen.The only thing I can do after it freezes is reboot the machine.Would anyone know what is causing this?Also, I keep having to move my optical mouse from the usb slot into a ps/2 slot.And the same thing with my keyboard. I have 2 keyboards, so I can plug in the old ps/2 keyboard instead of the new usb keyboard. (the devices keep flipping)My machine is an AMD 3400 with an Epox mobo. Nothing like this has ever happened before, and I have been using ubuntu for more than 4 years without any problems.
When I load XP in VirtualBox it starts off with the keyboard working. However, if I leave my computer for 10mins the Ubuntu computer/screensaver lock comes in. When I then go back to my VirtualBox I cannot select the CTRL-right to activate the keyboard. The mouse still works correctly but I cannot type anything.
Today my keyboard and or mouse repeatedly stop responding some minutes after boot. Currently the mouse stops responding after a few seconds of movement immediately after boot. Yesterday I used the machine most of the day, yet this issue didn't arise. Today I used it for a few hours before the issue developed. I did a full system update from the fresh install yesterday night. It's therefore possible that this issue has arisen as a result of the update, and that today the onset was delayed for some reason.
Earlier today I had the same problem with the keyboard. I replaced the batteries thinking that this was the cause. Now it looks like both keyboard and mouse are affected by the same problem. When the mouse stops functioning and the keyboard remains active, I unplug the mouse and replug it in, but it still does not respond, and only the unplug, and not the replug, are detected and logged in dmesg. I noticed ever since I installed Fedora yesterday that plugging in new usb devices after boot did not result in them being recognised, and that if I unplugged a mouse or keyboard and plugged them in again they would not work (requiring a hard reset). Currently the machine isn't usable as I cannot use the mouse for more than a few seconds. I haven't tried a PS2 connection, and currently I have keyboard access.

I haven't tried PS2. My keyboard and mouse appear to be working again (25 mins and still responsive).I unplugged all USB devices except for the keyboard, mouse, and wifi dongle. This appears to have solved the problem. Other devices that were plugged in were a USB to SATA external HDD caddy (powered off), and a serial USB connection to a Sheeva Plug computer (mini server). how I can use all my USB ports in future without this issue arising?
I use skype, and several times when i have it open, more often when i am using it, the hole system stuck with no response. The mouse stop moving, the keyboard does not work, even control + alt + backspace does not work! The only available choice is to reboot the computer.
I am running 9.10 (Karmic) on a Compaq Presario CQ60 laptop with Nvidia graphics. I have installed the -185 driver which has solved most problems. However every so often the system seems to lose track of the mouse button state. The first symptom of this is that all mouse movements on text are treated as if the left button is being held down: mouse movement selects text rather than just moving the graphics cursor. I am using a M$ optical mouse.
I have tried:unplugging and replugging the mouse using Ctl-Alt-F1 to go into a console and Ctl-Alt-F7 to go back to the GUI I am able to shut down all of the open windows normally using the keyboard, but the only way I have so far found to get the GUI working again is to reboot the system.
I've installed Ubuntu 10.04 on a Packard Bell laptop and I'm having some trouble with the trackpad and keyboard. At the login screen they both work fine, I can move the cursor and type in my password. But after I login they both immediately stop working and I have to use a USB mouse and keyboard.
I'm running a SuperMicro GPU server with nvidia GFX 750 card. Debian Sid with last update this morning. The server is far away from the screen. So i'm using 5m active USB 2.0 cable with one Belkin powered hub. All USB device work always correctly.
But sometimes, my keyboard (a logitech illuminated) doesn't work anymore. I need to disconnect and reconnect it. Backlight keep on but no key work. I can't change the numlock or caps lock too.
Apparently, this appear mainly (only?) when i use the keyboard (for shortcut or typing text in vim).
I've tried with and without autosuspend (setting manually or from GRUB).
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)
I'm running XFCE on slackware64-current. I've had this problem for a number of months now. Every so often, XFCE will decide to not recognize key combinations that are mapped to keyboard shortcuts. For example, hitting ALT+F2 will not bring up the xfrun4 dialog box. This happens to all of my keyboard shortcuts (e.g., volume keys).
For now, I've resorted to going into the keyboard shortcut settings and double-clicking on each assignment and then hitting ok. This seems to correct whatever corruption is occurring. What's even more unusual is that all of the settings appear to be intact in the settings box and even in the .xml file.
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.
Using Gnome and openSUSE 11.2 . Ok. I changed few keyboards to see if that is a hardware problem . Obviously its not. Whatever keyboard layout I choose .. same story repeats : USA , SRB, GER... I tried to change "key to chooose 3rd level option" in keyboard preferences: right alt, right win , left alt , left win ... but nothing works .
Upon logging into kde 4.4 the left mouse button (3 button usb mouse) becomes unresponsive on certain windows. For instance the toolbar may still respond to left-click while other windows on the desktop do not register it. However more and more windows/panels become unresponsive rather quickly. The same happens for right-click sometimes but far less often. Some functionality can be recovered by re-plugging the mouse.
Logging out and logging back in solves the problem until the next reboot. I have tried different users and wiping the .kde and .kde4 folders. The problem persists. I can stil work by relogging every time I turn on my computer but it does waste a lot of time so if there are any ideas I'd apreciate it. KDE 4.4 release 3 (There seems to be no updates in YAST available)
