Keyboard Hanging, in CentOS. Some time when I login to Linux or when we come back to use Keyboard after a long time work with mouse, my keyboard will hang for few seconds. I don't know its my USB keyboard problem or another issue. I doubt it started after I install opera browser in CentOS or by VNC setup.
View 3 Repliesi'm running ubuntu (32bit) on a quad core compaq presario with 3.9gb of ram and a 500gb HDD.sometimes when i have few windows open (nautilus, firefox) and i'm watching a movie the hard drive will spin up for no reason and everything on screen will hang for a few seconds.i did a hard drive check and everything seems to be ok there. i have a geforce 8600 gt with the recommended 185 driver installed.i'm wondering what the problem is? could it be hardware?
i've noticed this is happening from time to time, no matter what i'm doing. First the computer beeps then the hard drive speeds up and everything lags.
I've got a program that takes keyboard input with BufferedReader and readline(), but readline() is blocking so I can't increment any sort of counter to quit the application after a period of inactivity, because the program is just waiting for an input from readline(). Do I need to create multiple threads, where one thread counts down an inactivity timer, or is there some method of using non-blocking keyboard inputs?

I'm trying to install CentOS 5.4-x86 on a "new" motherboard, it's an ABIT Fatal1ty AN9 32X. I have a AMD 6000+ Dual Core running stable at 3.01 ghz. 4GB of ram(4x 1GB). nVidia GeForce 7600. 2x SATA II 160GB WD RAID 0 and 2x SATA II 1TB Seagate RAID 0. This setup has been running fine as a FTP server for months and has been flawless for games for about 3 years.Right off the bat during initial install it hangs before loading any GUI.Last lines:
NFORCE-MCP55: IDE controller PCI slot 0000:00:0c.0

I'm running into what is quite possibly one of the strangest problems I've ever encountered. We recently had a power loss, and some of our vmware instances didn't shut down correctly. Once of those is our Zabbix testing monitor. From that point on, whenever I run the "ll" command, my terminal freezes. This happens over both ssh and the local console. I've forced a disk check via the "shutdown -rF now" command, and it returned no errors. Since ll is simply an alias for ls, I copied ls (and the entire bin directory) from another Centos 5.3 instance, with no change in behavior.
View 4 Replies View RelatedI have just completed an upgrade from 5.3 to 5.4 (64bit) Now when the system starts it gets to Staring udev and then hangs for about 2mins before printing "Timeout" and then continuing.
At various stages during the boot process it just stops with no warning and takes a while to restart.
My boot time in 5.3 was about 50seconds, now with 5.4 it is about 4mins.
My issue is: I am "locked" on kernel 2.6.18-164, I just can't get my server up and running with any later release. It simply hangs at "Starting udev".
The hardware is:
MB: Asus M2N32-Deluxe
CPU: AMD Phenom(tm) II X4 920 Processor
Boot FS: Ext2
RootFS: xfs
RAM: 4Gb
I have 2.6.18-194.el5 running on other machines.
PS: I'm about to install/update a fresh 5.5 disc for testing purpose anyway. I'll update here if it works.
I'm running V5.3 (newly installed) on an FJ E8020 laptop. The problem I have is when shutting down (*not* rebooting). NetworkManager fails to stop and after (during?) the postfix shutdown, the system seems to hang.I cannot access via another screen or remotely. I can't find any clues in the log files.

I have an annoying problem with a 2 nodes cluster that I don't understand.
One of my server is totally shutdown.
When I start cman after a reboot on the other server, it hangs on "Starting fencing...". The process which is actually hanging is : /sbin/fence_tool -w -t 300 -m 45 join
When I start this program manually, I get this output :
# /sbin/fence_tool -w -t 300 -m 45 join
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
Waiting for all 2 nodes to be members
(and so on...)
What I don't understand is why the fence_tool program wait for the 2nd node to join the cluster and don't fence the other node.
Here is my cluster.conf :
<?xml version="1.0"?>
<cluster name="ctpsrv-bdd" config_version="7">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="20"/>
<cman expected_votes="1" two_node="1"/>
[Code]....
Would it be a good idea to edit the cman startup script and remove the "-w" option of command fence_tool join, so the command do not hang up ?
I'm trying to execute some actions when there's no keyboard action in "x" seconds or minutes (after "x" seconds or minutes of keyboard inactivity), but is hard to find something about this...
and i don't know if this will make a lot of cpu usage
for a x problem I reinstall the complete x packages. I remove some packages with force.Before this yum works perfect. Exact at this time we have problem with our internet connections and yum hangs somewhere when yum load the repositories and or start the update process.Now yum hangs at start from the command. I can start yum some times and no locking error is rise.strace brings:
stat("/var/lib/rpm/Packages", {st_mode=S_IFREG|0644, st_size=79855616, ...}) = 0
open("/var/lib/rpm/Packages", O_RDONLY) = 4
fcntl(4, F_SETFD, FD_CLOEXEC) = 0

I am running Centos 5.5 with all the GUI stuff, including nx server and webmin.Sometimes while watching the bootup messages because my eyesight is very poor.I hit <ctrl s> to pause the output so I can read some details. If I do this late in the init sequence - it often briefly stops the output then the screen disappears under a blue wash (presumably something to do with the GUI login screen ot screensaver??)but the login screen never appears. Also it seems that the script never completes because the imap, webmin and http servers don't appear to have started.
I haven't found any satisfactory way out of it. I can't get back to a console terminal (I've tried ctrl c, d, z, etc.). As luck would have it the nx server has started so I can open an nx session. If I open a terminal in an nx session as root.I can't do a normal restart (shutdown -r now). Nothing happens presumably it can't run the init script because it is still running.The only way I have found to get the system back to life is to run "shutdown -r -n now" in the nx terminal session.There are probably better ways out of this predicament that I am unaware of. Otherwise it is probably somewhere between an annoyance and a bug. I would be interested in any advice the centos "board" may have as to whether this is worth raising as a redhat bug.
I recently bought a Toshiba Portege M200 tablet PC and it's caused me no end of grief to load linux on it. I would like to load CentOS 5.x (because my hosting company uses it and I will be able to learn as I run it).
Here are my resources:
I found internet resources to create a boot disk that enables me to see my 8GB Sony USB flash drive via DOS. It works nicely.
I have a laptop drive to USB converter and can access the hard drive directly from my Win XP desktop. I have PowerQuest's Partition Magic Pro (v8.0) and can make Ext2 and Ext3 partitions at will. I have also loaded a program that allows Windows XP to read and write from Ext2 and Ext3. It works well.
I have tried loading boot images from PXE. This option is mostly out because it seems to be a couple levels past my competency (I haven't been able to get it to work).
Given those resources, what's the best way to load either the CentOS live CD... or some other approach?
Since I wrote this, I figured out how to make a boot floppy that can start an external USB CD-ROM/DVD drive. Here are the files on the floppy:
Here's the contents of my config.sys:
Here's the contents of my autoexec.com:
I can boot to the CD and launch linld.com. The problem is that I keep getting a kernal panic message, saying that a memory block could not be addressed. And when I add the following part to the line above: "initrd=d:isolinuxinitrd.img" the install fails and reboots. I have tried to expand the initrd.img and it appears... blank?
I just finished installing CentOS 5.2 x86_64 on a Dell Dimension 3100 (Pentium 4 with 64-bit support). On the first boot, after completing the final config steps (firewall, SELinux, time server, etc), the boot hangs on "Starting xend:". I have completed a successful installation on another Dell machine (different processor), with the same installation options (I recorded all of the steps and followed them for the second installation).
My boot commands in grub are:
root (hd0,0)
kernel /xen.gz-2.6.18-128.el5
module /vmlinuz-2.6.18-128.el5xen ro root=LABEL=/1 rhgb quiet
module /initrd-2.6.18-128.el5xen.img
This is probably not possible, but just wondering, restarted centos 5.2 remotely, hung at shutdown, kvm'ed to see what was hanging it up, control c'ed and then ctl alt del, just trying to kill the process, was brought back to the login screen, but unable to type anything. Alt-f1 switched to a different virtual console, which was just a blank screen and a blinking cursor, but now able to type things. Want to avoid hard shutdown. Is there anyway to force shutdown/reboot the machine from this console?
View 1 Replies View RelatedI recently added an external hard drive through a IEEE 1394 interface. I'm finding that during large file transfers the system slows to a crawl. It's still running: routing for example seems fine. But running applications are pretty much unusable: Apache is unusably slow, SSH login is very slow, etc. Currently I'm using the IEEE 1394 drivers from Axel's ATRpms but I'm pretty sure I saw this with the default kernel IEEE 1394 drivers too.
View 4 Replies View RelatedI have read all of the articles I could find on the problems. I am using the lilo bootloader as grub doesn't work. I have also added pci=nomsi to my lilo.conf and ran lilo -v. I can get the system to boot with kernel-2.6.18-8.el5. However I can't get the system to boot with kernel-2.6.18-194.11.3.el5.i686.rpm. When I boot with kernel-2.6.18-194.11.3.el5.i686 the system hangs after it prints bios data check successful. I tried adding suppress-boot-time-BIOS-data to my lilo.conf (I ran lilo -v after the change) and the system still hangs. The Optiplex 320 is running bios 1.1.12
Why won't newer kernels work? Is there a way to get more information to print before the hang to aid in debugging?
How can i change the seconds at boot , I have a image maybe i will help And how can i change the background,

Here are the specs code...
I have other servers on the same network with the same software/hardware that never loses its mount to the windows share, and nightly backups are run through those mounts. So why does the mount on this machine fail when we do a push? The only conclusion that I can come to is there is some sort of time out on the windows server that causes this. The other servers that have this same type mount use their share every night, where as the share on this server gets used once or twice a week. Once the mount hangs I can not unmount it, I have to reboot the server. Once the server is rebooted the push works fine. But then the next week when a push is tried it hangs. What else can I check?
UPDATE: I've also tried NFS mounts and autofs mounts and they hang as well
I enabled logging by echo 1 > cifsFYI and this is what I see in var/log/message code...
Ive removed the actual file names for security concerns. Any one have ideas as to why this is happening? The only other thing I can think of to try is to swap out the NIC but it's at a remote location so I can't do that right now.
I have Centos 5 Installation with following Linux ipmpls.mobilink.net.pk 2.6.18-8.el5xen #1 SMP Fri Jan 26 14:42:21 EST 2007 i686 i686 i386 GNU/Linux. I have Nagios running on it for monitoring switches. It also runs postfix to give email alerts in case of a switch is unreachable. The problem is that the server hangs for a minute and returns to normal operation. During this period if a switch is polled it cannot be reached and hence Nagios shows the Flapping state on the switches. I need to understand as to why the server hangs
View 1 Replies View RelatedI have had this issue for a while on my centos 5.4 dedicated server with 1and1. If I reboot my system, my connection starts and then drops in about 10 seconds after the system has booted.I connected through the serial console and noticed there was only one thing that seemed suspicious while booting. named could not start for some reason. So my question is - are these 2 problems related? If not, what could be the reason for my connection to drop?At the moment the only way of getting the connection back up is by running dhclient. This works until the next reboot.

I tried to find the information by myself (google search, forum search, Faq, manual...) but i didn't find any clue. I installed CentOs 5.5 on a macbook model 1,1 and I have currently two issues :
The keyboard mapping is wrong (it didn't fit with the macbook keyboard, ex: the '-' is not on touch '6' for example...). Is there a way to apply macbook keyboard mapping? I didn't find how to modify the brightness of the screen. Where is this settings? It didn't appear in the video card settings that is very basic. Do I need to install a proprietary driver for my GMA on my macbook? Also, i will like to have this settings on the keyboard with the dedicated button (like for the sound that works well).
I just took delivery of a new computer, with CentOS 5 installed. It does not have a PS/2 keyboard socket, only USB. I get lots of strange "key stuck" problems - usually the shift key or the cursor keys (I guess I use them the most). Or sometimes key presses do not register. It makes it very difficult to use the machine.I have tried two keyboards (both of which work fine on other machines, or on this machine when booted with a live CD). The machine is an Intel i7. Are there any known problems with USB keyboard drivers in CentOS?
View 4 Replies View RelatedI am having a problem during a fresh install of CentOS 5.3 on an IBM Intellistation Z Pro 6221. I have tested the installation media (CDs). The install runs normally until I am asked to specify the appropriate keyboard.I take the default (English) and hit next. The keyboard and mouse keys become unresponsive though the mouse pointer moves. I can go no further than this. This behavior is the same whether I install in text mode or graphic mode. I have tried the noprobe installation option without success. The box I am doing the install on dual boots fine between Windows XP and CentOS 4.7 currently.Does anyone have an idea of what the problem may be?
View 2 Replies View RelatedJust installed CentOS 5.4, had no problems until the first time it tried to login, where the keyboard didn't work. There are bugs logged on both the CentOS site, and the Red Hat site, but nobody seems to have a definitive solution (other than buy a USB keyboard). Bearing in mind that the machine in question is not hooked up to a network (i.e. no internet updates), is there a way to resolve this issue?

View 6 Replies View RelatedI'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?
