Debian Hardware :: USB Keyboard Stop Working Sometimes
Aug 4, 2015
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).

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 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.

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'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.

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.

They do work sometimes but then after a while, they stop working completely. I'm not sure why...

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'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.

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).
Code:
Section "Monitor"
Identifier "Configured Monitor"
Endsection

I can't spin down my internal windows SATA disk with sdparm anymore. It worked well in Lenny, but not in squeeze. The disk I'm trying to stop is not mounted or anything. Is this something udev related?

I upgraded from wheezy to jessie, but now I just boot to a console. I've gone through and made sure all packages are up to their latest versions, and I've made sure gnome, xorg, and xserver-xorg are reinstalled (during the upgrade they got uninstalled..).
Here's what happens when I run startx manually:
Code: Select allcharlie@asimov:~$ startx
X.Org X Server 1.16.4
Release Date: 2014-12-20
X Protocol Version 11, Revision 0
Build Operating System: Linux 3.16.0-4-amd64 x86_64 Debian
[Code] ...
Note also that this whole time, gdm3 has been running:
Code: Select allcharlie@asimov:~$ ps ax | grep gdm3
1058 ? Sl 0:00 /usr/sbin/gdm3
3993 tty2 S+ 0:00 grep gdm3
charlie@asimov:~$ sudo service gdm3 status
[Code] .....
I'm not sure why it prints that it's starting gdm3, but it does that every time I run `sudo service gdm3 status'.
Here's a copy of my /var/log/Xorg.0.log.

I'm a huge keyboard shortcut fan. I can't stand mice. So this is a big one for me.
My Alt+F10 (maximize) and Alt+F9 (minimize) keyboard shortcuts work just fine. I read everywhere (i.e., [URL]) that the Alt+F5 combo should unmaximize a maximized window. But it's not working. Can't find anything that says Debian excludes that combo.
Is this to be expected or is something amiss? I think its meant to be a default shortcut, so don't want to start playing around with customizations prematurely.
Searched through the forum, couldn't find anything under the following search terms: Alt F5; Alt+F5: Alt +F5: Alt-F5: maximize: unmaximize. Did I miss the magic string?

I just reinstalled Debian 8.3.0 "Jessie" on my laptop using KDE as the desktop environment instead of GNOME. Using GNOME I had no problems with the keyboard or mousepad but now changing to KDE my keyboard and mousepad won't work. It was obviously working fine during the install but now won't work once I login my desktop. I'm using a USB keyboard and mouse in the meantime.
I've tried going into System Settings->Input Devices->Keyboard and changing the keyboard model. Originally it had installed by default as "Generic 101-key PC", and I tried swapping to "Asus Laptop" but that made no difference. I tried a few other random keyboard models but that didn't make a difference either.
My laptop model is an: ASUS U40SD.
Any commands I can type into bash that could track down the problem.

I have debian with kde on a laptop with a built in ps/2 keyboard and touch pad mouse which have been working without problem since i bought the computer. However, recently i booted the computer up and all of a sudden the mouse and keyboard are not functioning. I know it is not a hardware problem because i can type in the BIOS password, make the selection between normal and recovery mode in grub, and can type in all of my passwords to unencrypt my hard drive.
Also, it recognizes the keyboard all the way up until the point where kde starts, at which point it loads a login screen with the mouse and cursor on the screen, but no ability to type, not even caps lock or ctrl+alt+f1 to switch to console mode. does anyone know why this is? I have performed not updates and have not changed the configuration of my computer so i am not sure why this would happen.
P.S.1 out 15 times when i load the part where i need to type in the passwords to unencrypt the hard drive the keyboard will stop working then instaed of with kde.

I was trying to tweak my video card's performance by configuring the xorg.conf file. There were many lines unrelated to the card there; so, to make the file cleaner, I decided to delete all the sections except the one I was dealing with. Obviously I shouldn't have done that. After rebooting the system, all the hardware that provided human interface stopped working. Now I have to find a way to delete that xorg.conf file. The computer is still connecting to the internet, and I have another computer running Debian available. Is there a way to access the broken computer with the other one?

After installing KDE USB keyboard and mouse won't work. They are added to /proc/bus/input/devices though.
I also tried to install Gnome; same thing.
I took #usb-devices and they were there also..
But #usbhid-dump did not generate anything to screen.

on my netbook I have a Debian unstable/sid system. A few days ago I did an apt-get (dist-)upgrade which I think also updated the X-Server. Since then my netbooks keyboard and touchpad are not working as soon as the desktop is started (I think gdm).
The Keyboard works during the Grub selection and also in recovery mode (Root Terminal), so I'm sure its not a hardware problem. Could it be that the X-Server unloads the kernel modules for those two devices?Also if I plug in a USB keyboard or mouce they are working.

I have Debian Jessie 8.0 amd-64 installed. It is a dual boot system with Widnows 8.1 alongside. Both the systems work fine with a few glitches coming at times on jessie. But I assume it should get stabilised with time.
Problem is:
The usb keyboard is no longer detected until the GRUB stage crosses.
* This implies I am unable to press F2 to enter into BIOS
* I am unable to chose Windows 8.1 by using arrow key on the keyboard.
When the default system (first in the grub list), in this case Debian is selected after time runs out then the keyboard comes back to life and works properly thereafter.
So far I have tried the possible solution given at [URL] .... but it did not work.
Some Information

I am suffering from the following problem: after updating udev from 125 (lenny) to 151 (squeeze) my wireless keyboard Logitech diNovo Edge totally stopped working (says it is disconnected). If I downgrade back to 125 all works fine again.

I has a look at the release candidate today as a live DVD and found that my keyboard settings were incorrect. I was obliged to remove the USA settings from the keyboard layout.
When I reverted to Karmic I found that it was necessary to correct the keyboard settings back to UK as somehow or other the settings from the live DVD registered.
It might be worth watching for this when testing/using live DVD before full adoption

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.

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'm just wondering if there is a way to keep the flash plugin from stealing the keyboard focus. This way firefox's shortcuts can be used regardless of what type of content is in the window.

I have updated to 10.10 and now my ir remote is simulating keyboard arrow keys which is causing problems in applications like Boxee. The weird thing is if I stop lircd it still simulates the keyboard arrow keys.
Does anyone know how to stop the keyboard arrow keys from triggering when the ir remote up, down, left or right buttons are pressed?
(Here are all the IR config files)
hardware.conf
Code:
# /etc/lirc/hardware.conf
#
#Chosen Remote Control
REMOTE="Streamzap PC Remote"
REMOTE_MODULES="lirc_dev streamzap"
[Code]....
