Hardware :: Keyboard Quits Responding, Alt-F3 And Alt-F7 Restores It?
Feb 23, 2011
I'm using a Toshiba Satellite P505 Intel dual core and 6 gig ram with 64 bit Ubuntu 10.10. Every now and then (often while using Open Office), my keyboard stops responding. I have not reliably been able to reproduce this. It seems somewhat random. Additionally, clicking on any of the Ubuntu menu items such as Places, or Applications does not pull down the menu. Mouse seems to work other than that. If I press Alt-F3 and then Alt-F7, everything returns to normal. Any ideas what is causing this or if there is a known fix?

I am experiencing problems with keyboard shortcuts. It started to happen after I installed gnome shell and switched back to gdk. the most annoying part is that every single keyboard shortcut works except the most used one AKA "run a terminal"
first I thought it had something to do with shortcuts in compiz but no. I changed the keyboard shortcut for "run a terminal" to something wild like CTRL+SHIFT+ALT+N and it still doesn't work. That command is not doing anything... Can i add my custom commands to keyboard shortcuts and how?

I'm using Ubuntu Lucid 10.4 on a Dell Studio 1537 Laptop with a Microsoft Comfort Curve 2000 USB Keyboard. Currently, my keyboard is not responding at all. It's been like this for half a day now. With the exception that it was working fine for quite some time, it used to periodically, and randomly do this out of the blue. Meaning I can come up with nothing logical to tell me why it stops working. The only hint is that the problem first occurred after my upgrade from Ubuntu 9.10.

Kubuntu 10.04 all updates until today.
All of the sudden my keyboard and mouse are not working any more. At login window keyboard is working OK so I can login (mouse is not working), but after login, keyboard is not responding unless I press the key for few moments (perhaps a second) until a keyrepeat begins. Only then key is accepted and echoed on screen.
Funny thing is, if I login as some other user, everything works as expected.
I have already ran Xorg -configure as su, but it didn't resolve the problem.

I just installed the new OpenSuSE 11.2 release and after coming up in graphical mode the keyboard and mouse are not responding at all.
After that via a remote login force the machine back to runlevel 3 and this makes it able to login to the console and trying to start sax2 to make a new X configuration.
Well it doesn't read the old configuration but gets stuck as well.
The install was an update from OpenSuSE 11.1.

On our SuSe 11.1 PC keyboard and mouse are no more responding although it did work properly until yesterday. We shut down the computer yesterday evening and today they do not work anymore. But it is not a hardware problem, we can use keyboard and mouse until Grub bootloader, but as soon as we start a Linux session (doesn't matter if normal or failsave mode) the keyboard and mouse are disabled, we can see that because the NumLock and CapsLock LEDs are switched off immediately.
We have no idea what happened. We booted from CD into rescue mode and mounted the hard disk manually and checked some logfiles, but the boot.log tells us that USB keyboard and mouse are detected, as well as the Xorg.0.log file. And we found no indication that keyboard or mouse are disabled or something like that.

I just upgraded from 9.10 to 10,4 via update manager and now when I switch on, the boot process seems to work but when I arrived to the login page, I can't use mouse or keyboard. The system is not freezed because I can see the watch on the lower right running properly.

I upgraded to 13.1 from 13.0 a few days ago. I have a Toshiba Satellite L3655D that I leave on constantly. Twice now, I have woken up to windows (urxvt and firefox) that don't accept keyboard input. I can paste into them and they respond, clicking is fine, but the keyboard either barely sends or is completely ignored - if I tap a bunch of keys, one or two might go through, eventually. New windows work fine, so I have to replace everything I have open.
edit:I switched to XFCE for 2 days and the issue didn't appear, but my other laptop with the same fluxbox settings also did not have any problems. I switched the original laptop back to fluxbox (and happened to upgrade the ATI drivers around the same time) and haven't had it happen since. If this happens to you, try restarting X.

I've just installed Debian Testing XFCE, and mouse & keyboard don't respond to any inputs. The keyboard works just fine in the Recovery Shell, that's why I suspect a problem with the XServer.

I recently installed suse 11.2 on my system and during the install the keyboard (Microsoft internet keyboard PS/2) and mouse (Microsoft optical mouse USB with scroll wheel) worked perfectly, but once I reached the login screen they both became unusable.
I also tried rebooting into failsafe mode but once reaching the login screen the same happened again, the only key that seems to work is the 'F Lock' key and the optical light appears on the mouse.

Yesterday night everything was normal until I rebooted to Fedora. This morning I switched back to Kubuntu 9.04 and the keyboard had a strange behaviour. Every button needs to be pressed ~2 sec. in order the letter to show up. And that happens in every application (shell, firefox, etc). I tried to upgrade to 9.10 hoping that it will return to defaults but the problem persist. Please help solve this issue, my work is hanging and all the programs I'm using at the moment are installed on my Ubuntu partition.

I have a Microsoft Wireless Keyboard 3000 v2 and Microsoft Explorer Mouse Model 1362. The biggest issue I have right now is with the keyboard. The keyboard will start cutting out and not responding to keys. As soon as the cpu load drops then all is well. I have a PS2 keyboard that I keep plugged in just in case the load stays high and I need to type something. The mouse and the keyboard have seperate usb dongles, and when the keyboard is having issues the mouse is still working great. This tells me that either the USB radio for the keyboard gets turned off, or that something on my machine is weird. I have seen the EXACT same behaviour on 32bit and 64bit linux distros.
CPU: AMD X3 720 oc'ed to 3.22GHZ
MOBO: Biostar
RAM: 8GB
Video: HIS ATI 4890 (using FGLRX)
HD: Samsung 1TB 7200RPM drive
OS: Ubuntu 10.10 (tested also with Fedora 14, OpenSUSE 11.3)
Note: it happens with very little load and high load. Of course high load it happens all the time.

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:

Is anyone else having issues with their mouse/keyboard responsiveness via Synergy after upgrading to 11.04?
If I plug mouse and keyboard directly into the desktop the issue goes away. But when I connect via QuickSynergy and share my mouse/keyboard the mouse is very slow and has low sensitivity.

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.
Hardware:
Fujitsu LZ945230BH1 USB Mouse
Microsoft Arc Bluetooth Wireless USB Keyboard
Running Fedora 14.
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 am learning linux commands. I just wanted to see what happens when I type
Code:
The screen became blank. Keyboard was not responding. I couldn't do a proper shutdown. I switched off computer by pulling out the plug. When I restarted, I heard a series of beeps (approximately 10 beeps). Then I was dropped to the grub prompt. The problem now is I can not type anything into the grub prompt, because the character 'c' is continously printed across the screen like this:
Code:
I couldn't stop the character 'c' from printing (I tried pressing Esc, Ctrl+C)
The solution is easy. I can reinstall grub from a livecd. Or even reinstalling the entire operating system wouldn't take more than 30 minutes. But I want to know:
1) What exactly happened to grub? What stage does this error belong to (1, 1.5 or 2)? What is the error number?
2) How can running "sudo kill -9 -1" affect grub?

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.

My trusty 11.04 x64 Ubuntu desktop machine stopped booting up properly about 2 weeks ago - it goes through Grub and into Plymouth, but then freezes and stops responding to keyboard input either on a dark purple screen, or less often the same but with the Ubuntu logo and the 5 boot progress circles but with none of them lit up. I can hit escape early on after grub and see initialisation reports showing everything successful (other than a fail on "Automatic crash report generation") - up to a line saying "Stopping System V runlevel compatibility [OK]", at which point it freezes.
Going into recovery mode allows me to fsck the disk (which is fine, and smartctl reports all attributes as fine), fix packages (which I have done a number of times, to no avail) and boot into safe graphical mode, which works fine, albeit only on one monitor and with very poor graphics performance, obviously. As the machine was borked and everything was backed up on my fileserver anyway, I decided to nuke it and give Fedora a go (I've been using Ubuntu since Feisty and it was a good time to try something else). Fedora was fine (and worked with the default nouveau driver), but I didn't like it, so after less than 24 hours away from the fold I decided to come back to Ubuntu.
At least a reinstall should fix the problem with booting, right? Wrong! The live CD worked fine, installed perfectly, and the machine behaved itself upon first reboot - at which point I ran apt-get dist-upgrade, restarted, and blam - right back where I started. Updated vanilla Ubuntu 11.04 will not boot. Has Ubuntu released a dodgy package that has broken my x server? I don't want to have to go back to 10.10 -

It's two days now I'm in deep troubles after my last "yum update". The system boots as usual, the graphical login pops up the normal way but no input is handled by either the internal keyboard (the system is a laptop), the mouse pad, the external USB mouse and keyboard.
The hardware itself seems to be working as I can pop up the BIOS menus and even edit the GRUB booting line. But, after GRUB there's no possible input. I've tried to boot the system with the Fedora 11 DVD, rescue menu and then chroot. This in order to run a "yum update" in the hope that the problem was in some broken update. No chance: there's no update.
My questions are:
1. Is there a way to boot Fedora withou any graphical interface from GRUB (or anything else to skip the KDE)?
2. Is there a way to have the (cabled) network activated at boot *before* the graphical login?
3. What the he** is happening to my otherwise pefectly working laptop?

Lately, my ISP has started making all Google sites inaccessible for a short time every afternoon (last 3-4 days now). I suspect some kind of DNS poisoning... access always comes back later in the afternoon.
When access does come back, non-Linux machines can connect basically right away, but my Ubuntu machine (the primary one I use) seems to need a reboot, as if wrong DNS information gets stuck in the session and the reboot clears it so that the machine can get the correct IP address.
I have not installed nscd, and IIUC the OS should not be persisting DNS cache information without that package. Every reference I can find online to clearing the DNS cache seems to depend on this package.
The objective is just to get back in touch with my Gmail without having to reboot (since e.g. OSX doesn't require a reboot for the same). What should I do?

I've been working on getting another OS installed on my computer for one of my classes (OS specific assembly instructions). To get this OS running, I had to start using a GPT rather than a MBR table. I backed up my Ubuntu partition (ext4) using the old-fashioned dd command. I've since been able to get everything working again after a dd restore.
The problem is that my original Ubuntu partition was only about 50GB and the dd image only takes up 40 GB. After I restored the image to the new drive (146BG), gparted is reporting 119GB used and only 26GB free. What can I do to reduce the size of my install to 40GB again?
When looking at the disk in baobab, it says the the filesystem is only 47.2 GB and that only 20.9 GB has been used. This is likely what the old partition's breakdown was. So my new question is: How can I make the filesystem capacity (47.2 GB) equal that of the partition that it is on (146 GB)?

Since upgrading to the final version of 64Bit Natty, I have a problem with the mouse randomly freezing, I cannot do anything with it. So far the cure is to press enter, which also sometimes starts a program or logs out, but not all the time. In fact generally it just unfreezes the mouse and I carry on!It is though rather annoying so if there is a solution to this I would appreciate it.It never happened with the Beta versions just the final one!

(I am new to Ubuntu though have experimented with various Linux flavors in the past.) I have been struggling with this issue with Firefox 3.6.17 on Ubuntu 10.10. When I start Firefox it always loads the previous session's tabs, though I have the option set to load home page, not restore tabs. Where would it be picking this up from ?

How can I uninstall grub? I have have dual boot between Gentoo and Ubuntu and I want to use the grub, that is on Gentoo partition, as its my main system. I would not care about it as it takes almost no space, but Ubuntu automatically restores its own bootscreen after updates. This is annoying... How to get rid of it?

On October 9, I had a Dell GXS260 1Gig memory 80 gig HD, running XP-pro and Ubuntu 10.4.I downloaded and burnt ISO's for Desktop and Netbook for 10.10.the screen would get purple and blink 5 dots at me and then kill the keyboard and keep blinking the dots until it did it 15 times and then just get real quiet and just quit.After looking at articles on installing, I have run the memtest and the disk check and I have burnt the ISO's at 4x rather that 32x.I can boot back to XP (where I am now) and I can run Knoppix. Knoppix is a good way to look at /var/log/ for whatever that's worth.
Why the trial run does not work for UBUNTU is a complete mystery since KNOPPIX runs.For future releases, I suggest that rather than five stinking, blinking dots, two number show up as in 38/657 meaning that we have finished step 38 of the 657 steps.My questions: Should I delete the whole Linux partition?Is there something that I can rename or delete in the root directory that would alert the installer to try harder.It seems that the installer goes so far and then just rolls over and does nothing. (fifteen minutes of nothing is nothing)Is there a log of how far the live-CD has gone before it quits?Why does GRUB use 10.10 on all of the 20+ options that he shows? I have been running Ubuntu Linux for about four years now and I think the earlier versions left the GRUB version intact. Not that I ever booted into an earlier one. I am losing interest in installing 10.10 or even trying to make the live-CD run.

Since the latest update the gnome main menu quits unexpectedly whenever I try to select any funtion e.g. shutdown. In addition the network manager does not show up and does not configure the network (wireless). This behavior is since the latest update last week. Has anybody seen this as well? How can I revert to the previous state?
