CentOS 5 :: KDE Keyboard / Mouse Freeze / Buggy When Alt-tab'ing / Switching Between Windows

Jun 13, 2010

I'm a long time user of CentOS 5 w/KDE 3.5. I have always had this problem to various degrees no matter what installation of CentOS 5 I'm currently on. This same hardware does not exhibit the same symptoms with another OS.The problem is I regularly have many konsole instances open. I alt-tab between them frequently. Inevitably a random alt-tab will freeze the keyboard and the mouse won't be able to click anything although I can move the mouse cursor around. I can't type anything. It seems to have some sort of timeout and it always come back to responsiveness.

I alleviated this problem (I think) by switching keyboards, installing the nvidia driver instead of the nv driver, shutting down all non-essential services.I have seen these symptoms on every system I have installed CentOS 5 where KDE 3.5 was also installed. Very different hardware setups each time.Has anyone else run into similar symptoms?I'm surprised that it's just CentOS 5 w/KDE 3.5 that exhibits this behaviour on the same hardware where other operating systems (gentoo, suse, etc.) did not exhibit these symptoms.

Ubuntu :: Mouse And Keyboard Freeze In 10.04?

Aug 13, 2011

The mouse, and keyboard, freezes at random times? When I search the discussion boards for a solution to this problem, it is overwhelming to see how many others are having the same difficulty, yet I haven't come across specific solution(s) to the problem. (One posting has over 180 pages of comments!) I am still using Jaunty but would like to move up to 10.04, which I have installed on a separate partition. Unfortunately, that partition can't be used by my family because it freezes at random times! Naturally, I am unable to get any more updates with Jaunty. (I never had problem with Jaunty freezing.) Incidentally, I tried Linux Mint, which was a adaptation of Ubuntu 10.04 and had the same problem.

Ubuntu :: Random Freeze - Neither The Mouse Or The Keyboard Will Respond

Jun 14, 2010

I am running Ubuntu 10.04, randomly while working in gnome with no particular application I get a freeze periodically. Neither the mouse or the keyboard will respond. I am running it on a lenovo Z61m laptop. I have had previous experience with Posix systems but I am a recent migrant from XP as my primary operating system. I never had such an issue with this computer which leads me to believe that it is not a hardware issue.

Debian Multimedia :: Keyboard And Mouse Freeze After Login In Squeeze

Feb 10, 2011

I have a problem with mouse and keyboard. Both freeze within 30sec to half an hour after logging into squeeze 64bit (using gnome). My hardware is Asus P7P55D EVO (tested with linux according to ASUS) with Intel i5 760 CPU. I use IBM keyboard and Trust PS2 mouse. I also have MSI HD4350 graphics card, that was at least listed on Ubuntu to be supported, worked fine also with Lenny.

When using same combination with Lenny (64-bit) I never found any problem with either keyboard nor mouse, even running long nights. However there was need to upgrade to Squeeze since it has newer kernel supporting the sensors on board my MB. I used same mouse and keyboard also on Ubuntu 9.10 and had never problems. However when I upgraded to new MB I started with Ubuntu 10.04 64 bit version and experienced same keyboard and mouse freeze as I have now in squeeze. Only way out from this status is hard reset using PC reset button.

I connected with putty to my linux box and found following (while the linux box was on frozen state) from dmesg on keyboard: :/var/log$ dmesg | grep -i keyboard [ 1.064628] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input0

Ubuntu Installation :: Multip GPU - ATI HD 3600 - Mouse And Keyboard Freeze?

Apr 30, 2010

Multi GPU - Mouse and Keyboard Freeze once enabled Previously on Ubuntu Karmic I had multi GPU setup without a problem.System consists of three ATI radeon HD 3600 series (multi head) running 6 monitors.

Setting it up was was easy as on Microsoft windows. All I did was download the ati catalyst and issue the following command: aticonfig --initial=dual-head --adapter=all

That created the perfect xorg.conf. With the amdcccle desktop, I then rearranged the monitors around to my setup and enabled xinerama. I thus had a total of six monitors working without a problem. (Naturally with compiz turned off).


Yesterday the update manager popped up Lucid Ubuntu 10.04 Release available. I upgraded. I got the same issue of fglrx.. Reading through Forum I deleted the /usr/share/ati folder. uninstalled the catalyst. Rebooted in safe mode and then re-installed via synatic fglrx and amdcccle. All went well.

I then issued the basic command.

aticonfig --initial -f

This created the standard xorg.conf. On rebooting machine. My first two screens (off the first Radeon HD 3600) worked fine, without a problem. (See attached file)

I then issued
aticonfig --initial=dual-head --adapter=all.
This created the long xorg.conf file for all the cards on the system to work.

BUMPER !! Machine reboots and right before the X login screen appears all of a sudden my monitor screen goes into "Digital Power saving mode" and the monitor goes to sleep. Keyboard and Mouse are not responsive (All freeze). No alternative but to cold boot the machine and restart.

I have tried everything, each time mouse and keyboard just freeze.

Ubuntu :: Random Mouse/keyboard Freeze In The Login Screen?

May 1, 2010

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.

Ubuntu :: Compiz: Mouse Cursor Moves When Switching Windows?

I've been looking for an option to turn off for this, but haven't found any, and Google hasn't been helpful.When I switch windows with alt-tab, or a window requests focus, compiz warps my mouse cursor to that window. How do I make it stop?

Slackware :: Mouse Randomly Quits Clicking And Scrolling And Windows Freeze

Jul 20, 2011

Unfortunately, I've encountered a disaster the likes of which I've never seen before:Yesterday, in slackware 13.1, while using firefox, the window would no longer move or resize, and I could no longer click on things in that window.While this happens, the icons in xfce4 panel no longer acknowledge that the mouse is rolling over them, so I can't launch terminal from a panel, etc.; however I am still able to right click on desktop and open terminal and other apps that way.Since it was high time to upgrade to 13.37, and since I was experiencing weirdness, I decided to do a clean install: I actually repartitioned my drive, and reformatted the partitions (all xfs, and after backing up my data, of course)...

I don't know if that's significant, or not. there seems to be some lines in /var/log/Xorg.0.log about my logitech mouse.way too complicated to write by hand.I will log out and back on... sometimes that frees up other windows. Then I'll add the Xorg.0.log.

Ubuntu Installation :: Parts Of Keyboard Freeze / Keys Do Not Response In Kubuntu & Windows 7 Login Screen?

Jul 12, 2011

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.

CentOS 5 :: Keyboard And Mouse Won't Work In GUI?

Apr 1, 2010

I've just installed CentOS-5.4 on an AMD64 box, dual boot with Windows 7 64, if that matters. At first I could not get the GUI to display at all, but fixed that using system-config-display. During installation, the keyboard (HP bluetooth set with mouse) worked fine in the GUI, but mouse did not. Now when it loads the GUI interface after booting, neither the keyboard or the mouse will work at all, therefore I can't navigate anywhere. I have done the yum update already as well, from init 3, but they still are not working. what I should do next, where to check?

CentOS 5 Hardware :: Keyboard And Mouse Not Working Over KVM

Jun 3, 2011

Ive got a ClearCube Blade server installed with a mirrored clone of a Centos 5.4 system. Running X with GNOME. Upon starting the new blade, i find that I am having issues with the keyboard and mouse. When I plug in USB mouse and keyboard directly into the blade they work fine. When I hook the use mouse and board to the cport kvm, I don't even get any power to the devices. If I plug in ps2 mouse and board through the kvm, I get power and can use them in the bios but once Centos starts to load, they go dead. I have changed the kvm 3 times with new kvms, and I spoke with the manufacturer there are no incompatibilities with the hp mouse or keyboard or any reason why the usb ports wouldn't be working on the kvm for the devices.

CentOS 5 :: CentOS Installs A Buggy Version Of Synergy

Mar 10, 2010

As I use a (CentOS) Linux computer and a Windows XP PC side by side, I decided to install Synergy, a software to use one computer's mouse and keyboard on neighboring computers too.However, Add/Remove Software installed Synergy Plus 1.3.4-1 instead. That mostly works... Except there's a known bug on Synergy, see bug 2955158: if you use Synergy Server on CentOS to control the Windows computer, as soon as you touch the keyboard when focus is in Windows, it freezes. (I can still ssh into CentOS, but its GUI is unusable.)

Well, Synergy-Plus 1.3.4 inherited that bug. That makes it, for that purpose, useless.So I uninstalled Synergy-Plus and tried to install the lower version, Synergy 1.3.1-7, as per the recommendation in the comment on that bug report, except: I ended up with Synergy-Plus 1.3.4 again.I tried again from the command line, using yum, to no avail: yum told me Synergy 1.3.1-7 was obsolete and replaced by Synergy-Plus.I had to exclude Synergy-Plus from installation with yum, with "-x 'synergy-plus-*'", to finally get Synergy 1.3.1-7.

There, I don't have this problem. I do think that making people upgrade to Synergy-Plus 1.3.4 is a mistake.It's still not perfect. With Windows as the Synergy server (and using the Windows keyboard), if I try to type a ">" (on an AZERTY keyboard), it types "´┐Ż" instead); and I seem to have an issue to copy text from Windows into CentOS.With the roles swapped, using CentOS as the Synergy server and with the CentOS keyboard, I can copy from Windows. I'm still not sure what is the cause of this.

Ubuntu :: Freeze After Switching Video Mode During Boot ?

Oct 8, 2010

I just bought an Asus TS mini server. It has an Atom CPU (N280), and an Intel 945 chipset.

I installed Ubuntu Server Edition 10.04, that went smooth.

But on first boot, I see it hanging just after it mounts the swap. Now I don't think it has anything to do with that, the problem seems to me that at that point, it also switches the video mode. I guess that's where the problem is caused. It just freezes, no kernel panic, no reaction to the keyboard.

The system is dual boot, and the other OS is Windows Home Server. I put an ext fs driver there, and tried to read the logs, but don't get a clue from there. In particular, syslog doesn't even exist. Also no X log.

General :: Compiz Stops Updating Windows On A Multi-head System - Keyboard And Mouse Still Alive?

Dec 8, 2010

I am running Fedora F14 on an Intel I3 cpu w/4Gb memory and plenty of disk. I have two displays connected to the Gigabyte Motherboard, one of the HDMI connector, and one on a DVI connector. I run Gnome. When Compiz is enabled things work fine for a while, meaning hours or days. Then the displays will "freeze" to the point where the clock stops updating. The system itself is still running programs, services, and the mouse and keyboard work. The mouse cursor will move around, but nothing can be clicked upon. If a terminal was the open window, typing on the keyboard does not do anything, nor does ctrl-backspace or whatever it is to terminate X windows. The keyboard does allow me to press ctrl-alt-F2 to switch to one of the base consoles. Once there I can type to my hearts content. I can kill off my logged in Gnome session through the console, and I can shutdown the system in a controlled manner.

It is as if all of the windows stop updating. For example, I play music through Amarok. An hour after I stop using the system but letting the music play the screens will do their lockup. The clock will stop, and Amarok will stop updating which song it is playing. It continues to play each song in the playlist, but the Amarok window shows what was playing at the time that the clock stopped. I've also had this happen to me while using Yumex, where it would stop updating the screen while installing programs, but the programs do get installed. With Compiz off I don't have this problem.

The version of Compiz I am using is currently 0.8.6-3. It is running on Gnome 2.32.0-2, with a Linux kernel of It has happened with earlier versions of these programs. I am using the graphics processing the Intel i3 chip to the motherboard connectors. The freeze generally happens at some random time while I am not actively using the system. It has happened to me while doing simple things like programming through an IDE. The really strange thing to me is that the cursor will move around on the screen after everything else stops updating.

Ubuntu :: Keyboard Layout Switching In 10.04

Sep 19, 2010

A few months ago I upgraded one of my Ubuntu boxes to 10.04.1 and haven't been able to switch keyboard layouts ever since. I have US and Russian Phonetic keyboards and used to be able to switch between them using the keyboard switching panel applet back when I was using Karmic Koala. Now the applet is gone and not even available in the list of applets.

I understand the applet has been removed in the new Ubuntu. But why? And what other means of switching keyboard layouts are available now?

The trouble is that I have never been able to switch layouts without the applet -- none of the keyboard shortcuts I tried under Preferences > Keyboard > Layouts ever worked in any version of Ubuntu. Now I can't even test the Russian layout inside the Layouts tab, i.e. when I select Russian Phonetic and type something in the test box below I keep getting US layout characters.

General :: Non Cyclic Switching Between Keyboard Layouts

I have three keyboard layouts: en, ru and ua. Now I switch between layouts by pressing Ctrl+Shift (en->ru->ua->en->ru...). Here is part of my xorg.conf

Option "XkbRules""xorg"
Option "XkbModel""pc101"
Option "XkbLayout""us,ru,ua(winkeys)"
Option "XkbOptions" "grp:ctrl_shift_toggle,lv3:none,ctrl:caps,grp_led:scroll,caps:internal,compose:ralt"

I want to setup non cyclic switching with next sheme:
CapsLock - switch to en
CapsLock+Shift - switch to ru
CapsLock+Ctrl - switch to ua

I've read an xkb manuals and some articles about it but can't understand how I can setup xkb for non cyclic switching.

Ubuntu :: Switching Keyboard Layout In Console Only?

Feb 7, 2010

I am logging into an Ubuntu 8.04 machine using ssh, so I use a console. The keyboard layout is US-standard, obvioulsy. However, I would like to use french-canadian keyboard layout. And I don't know at all how to switch it in console. Give me Gnome or KDE, and we're done. But this is console only. I guess it has to do with the loadkeys command. Ok. I retrieved from the web a file cf.map.gz. Maybe ubuntu requires a different kind of file? Using "locate cf.map" I get nothing, except the file I have downloaded. Any package I should demand to be installed? (if yes, what do I do once they are in?) I tried using both the .gz and uncompressed files.


loadkeys cf.map.gz
Couldnt get a file descriptor referring to the console


loadkeys -u cf.map.gz
Couldnt get a file descriptor referring to the console
Loading cf.map.gz


They tell us about some program, console-data, using root privileges. Intriguing, but I am only a user, and do not have any root privileges. The system admin. has never used another keyboard layout, and knows even less than I on this matter. I tried similar stuff on my openSUSE at home, on a newly created experimental account, and I am equally unable to change within the console the keyboard layout (similar error messages).

Ubuntu :: Right Mouse Click Freeze / When Right Mouse Button To Open Options Menu It Freezes And Does Not Open Menu?

Sometimes when I shake my mouse left/right a bit it opens that menu, but this does not work always. It seems like xserver issue, but I'm not sure since I'm not expert in linux yet. It's very annoying issue that I would like to resolve asap.

Debian Multimedia :: Switching Keyboard Layouts Doesn't Do Anything

Feb 21, 2015

I cannot get to type in romanian letters (just a standard US keyboard layout that has those letters mapped to the puctuation keys next to Enter) when switching from US to RO. Here's what I have in /etc/default/keyboard:

Code: Select allXKBMODEL="pc104"

I can switch between the layouts, as fbxkb indicates, but instead of being able to type in the said letters, I get the punctuation marks you would normally get on a US keyboard.Yes, I have restarted after configuring the file mentioned above, and yes, I was able to use this layout properly on my last CrunchBang install (which I had to wipe and reinstall unfortunately).I'm on CrunchBang Linux, with Debian unstable repos.

Debian Multimedia :: Inconsistency In Switching Keyboard Layouts

Jan 7, 2016

I had debian 7 with GNOM,XFCE and LXDE woking fine. After I upgraded it to debian 8 (the DE mentioned also upgraded to e newer versions) I started having problems with switching between US and RU keyboard layouts. It now behaves as if I have two US layouts and one RU, so when I press CTRL+SHIFT several times the layout changes as follows: US-RU-US-US-RU-US-US-RU etc.

This happens in all the three DEs installed. If I exit a DE using CTRL+ALT+F1 to the command line the layout switches normally. So I guess something wrons is with DEs.

My /etc/default/keyboard file reads as follows:

Code: Select allXKBLAYOUT="us,ru"
