CentOS 5 Hardware :: USB Keyboard Disabled After Lengthy Screensaver Period?
Aug 31, 2009
Screensaver mode was engaged in KDE via Control-Alt-L. Then after a while the screen when blank. I was able to get the login screen by moving my mouse; however, the keyboard was somehow disabled. It would not transmit any input. I hit cancel with the mouse and the keyboard could not bring up the login dialog box. This doesn't happen if the screensaver is engaged briefly - only for an extended period of time (perhaps 30 minutes)

I have this strange problem with screensaver (in fact i dont know if it is the problem, but it seems to be), i describe the problem next:I have a computer with debian squeeze installed. I use this computer only as a dumb terminal for showing information about companies, this means that it have no mouse nor keyboard connected to it. I configure autologin for a not-provileged user and autorun one app.
I disabled the screen saver for obvious reasons. This all works very fine. The problem is that when connect to the computer with ssh and reboot it, 10 minutes after started the monitor goes dark, as if the screensaver gets activated, then i connect a mouse and do some moves the screen goes to the normal functional state, then disconnect the mouse and it never goes dark again, after 1 day even!. When i turn on the computer with mouse and keyboard connected, just 20 seconds after started i disconnect those both, it do the same (after 10 minutes goes dark), but if wait for 1 minute usgin the mouse and keyboard and then disconnect both, the screen goes dark thing never came out. It just appear to happen at some point when the system does not detect any input.

I'm running a fresh 10.04 x86-64 on a thinkpad w500, using the default video driver. The monitor shuts off randomly, sometimes while I'm using it and requires me to trigger sleep mode and waking up to bring back the screen. When it shuts off, everything else seems to be running. (i.e. its not going to sleep) I've turned off screensaver, sleep, hibernation and installed the Caffeine util to no avail.

I have a HTPC and need to be able to activate screensaver using a hotkey. (Screen lock won't work, don't want to enter a password).

Problem: When my screen saver kicks in after idle timeout and I get back to my desktop the keyboard is unresponsive in already opened applications with text fields. This happens with and without the password required after screen saver is engaged. This doesn't happen all the time and seems to be transient. It happens at least once a day, but not often.
Workaround: The mouse is still usable, so I open a terminal and hit a few keystrokes. The keyboard is now responsive and I can go back to typing in the open applications that I previously had open prior to the screen saver being engaged.

Im looking for an app pr line of code that could let me observe a process, save the info in a number of variable and then put the gathered info on a file.
Ive been trying with variations of top but no luck. I am running several CentOS virtual servers, VM is 2gb ram 2 processor.
Maybe a script that works over a specified amount of time while writing lines with the info on a text file so at the end i can have a sort of table with the data.
The thing is Im going to stress test the server and I would like to have the data to make some statistics.

I'm using centos 5, kernel 2.6.18-164.11.1.el5I have occasional server network problems (the NIC driver will basically crash/restart causing no connectivity for a period of time) due to the marvell sky2 NIC driver being a problem, as discussed here: This essentially means the server is unreliable when under any kind of reasonable load, to put it mildly.Worse still, the driver problem has not been resolved in 2.6.18.x - but it seems to have been resolved in the latest Linux kernels.I really don't want to compile the kernel from source, etc, but it looks like I may have no choice.Is there a repo which has a pre-compiled 2.6.20+ or 2.6.30+ kernel which I can use,

I am quite experienced in installing openSUSE. (I used it for many years.) But the problem showed below tricks me out.
I just tried to install openSUSE 11.2. In initmode 3 the keyboard works well. Everything worked well up to the moment I started runlevel 5. In XWindows Modus, the keyboard and the mouse are disabled. And I cannot get back to any other Virtual console.
When I started sax2, I get something (in the file /var/log/Sax.log) or both mouse and keyboard like this:
It indicates , mouse and keyboard are disabled.
Here are my questions:
How can I ENABLE my keyboard and my mouse?
Where is the file that configures sax2?
Do I have to set ("on") the AutoAddDevices? or to "off"

The issue I've been having is with Flash on websites; most notably, Livestream's Flash-based browser viewer, and Adult Swim's flash-based games. Clicking works perfectly fine, but the keyboard input is entirely disabled for the Flash area. Text boxes, or game controls, won't respond at all, even when everything else is still working.The only way to input any text into Flash-based text boxes is to write it somewhere else (Firefox's URL or Search bar, or in GEDIT), then copy+paste into the tect box (again, Ctrl+V won't work, only right-clicking and pasting will go through).
I've tried multiple versions of the Adobe Flash player, including the installer directly from Adobe's site, the adobe-flashplugin package in Synaptic, the flashplugin-installer package, and I believe I tried GNASH as well (although I'm not sure if that did anything).I haven't had a chance to attempt to downgrade either one yet, however, nor have I been able to test another browser.I've seen a few other issues of this sort pop up here before, but they've all either gotten no solutions, or they're a year or two old, or they're running into 64-bit-specific issues. Hopefully this is posted in the correct location, and fingers crossed someone has an answer (or better yet, a solution).

I've installed SalixOS LXDE and thought it was the best thing but... After I disabled almost all services except syslog, dbus, and hald while inside lxde desktop. I rebooted and my mouse and keyboard no longer worked. So then I booted my Slackware install and edited /etc/inittab on the salix partition so I could boot into init 3 (I kinda like init 3 more than 4 anyway). Booted back into salix and keyboard seems to work but gpm doesn't... Gpm can't find any mouse so I do an lsmod and there's only about 4 modules loaded? Crap... So I dig around /etc/rc.d folder and I think it's got to do with me disabling the udev services when everything was fine after a fresh install...
I ran the init script for udev but it does nothing... I also ran pkgtool and went to setup, selected services and hit enter but it jumps back to the main menu?! I don't know if that's a glitch or what but it won't even let me pick the services with pkgtool... So what can I do to change everything back to their default value? I only booted once into my new salix install, changed services, rebooted, and then problems... I really loved the way everything was working on my first boot. Salix is one of those distro's that really gave me a happy feeling with linux so I'd really hate to stop using it over this one wrong thing I did...

we are using firefox-3.0.15 from the CentOS-Repository and the adobereader plugin from the adobe-repository. We have a curious problem with adobereader-plugin in firefox.When a pdf document is displayed via the plugin, i.e. within a tab in firefox, all input fields are disabled. I cannot enter a search string or fill in fields. The cursor and page up/down keys are also disabled. But when I configure firefox to open pdf documents with the external acroreader, everything works fine.
Additional notes:* We are just migrating from SuSE. Some user profiles are working as expected without problems. Unfortunately, I was not able to figure out the important files: I traced all of firefox' file operations on the user profiles, but there are no significant differences between working and non-working profiles (I just compared filenames, not content).* the same adobe-plugin works with firefox 3.0.15 from mozilla.org* I also set up a clean i386-Centos 5.4 from original CD, SELinux disabled, updated and created standard user. I only added the adobe-repository. The same effect, no search avaible.

There's an OSS screensaver on windows that I love called PixelCity (links:blog post, github). it's pretty cool. and it runs fine on my Ubuntu (Karmic 9.10) with wine.Is there a way I can tell the gnome-screensaver about it so I can use it as one of my screensavers? I'm still fairly new to Gnome and the whole "screensavers as themes" thing is still confusing me.I've found my themesdir and tried to create a .desktop file for it, but obviously I've gotten something wrong as it just doesn't show when I open the screensaver prefs dialog, no error, no message, it's just not there.
Installing the xscreensaver packages added the extra screensavers I was missing, and I'm a pixelcity away from perfection..Of course the perfect solution would be if someone ported the screensaver natively to linux, which shouldn't be too hard as the source is open, it already runs on openGL and tries to confine most windows stuff to a single file. But I don't know C++ or 3D code or win/linux internals so I wouldn't know where to start..

For security reasons I need to ensure all of my users screensaver is set to come on after 10 minutes of inactivity. My thought was to find the screensaver config file, modify a setting in the file to 10 minutes and change ownership of the file to be root (so the user can't undo my changes either in the file or via the gui). However, I can't find the screensaver config file to do this. I'm running Centos 5.2. Anyone know where I can find the screensaver config file?

Does anyone know a way to activate a screensaver at the login screen? I've got about 5 machines here, and I'd really like the ability to just have the screensaver come on after 5 minutes of sitting there with nobody logged in...
Even a way to blank the screen would be nice. However, if we were to blank the screen, I need to ensure that it doesn't do a DPMS blanking, since we use calibrated monitors here, and turning them off sucks.

I am trying to get the KDE Media screen saver working in GNOME. Is there a way to use kde's screensaver program in gnome on startup, instead of gnome's screen saver program? Basically, I am trying to disable gnome's screensaver, and load kde's program in its place at gnome startup.

I can't get CentOS to stop seeing my drives as a fakeraid, even though I disabled the raid settings in the bios. Therefore, I can't install. Previously, this box was running Vista 64 bit. I have an nVidia mainboard and two 500 GB sata drives. The mainboard offered raid support, so I enabled it. Windows saw the drives as a single raid0 drive and installed on it flawlessly. Never had a problem. Two days ago, I finally got off my horse and decided to get rid of windows and install CentOS. I left the raid intact, installed CentOS on the fake raid. Upon rebooting, GRUB wouldn't load. Booted up a live disk, fdisk saw the drives separately but couldn't read data from them.
Tried a second install, same problem. Wiped out the the data on the drives using gparted. Tried a third install, same problem. Did some research, found out that my raid was really a fakeraid and that a better option for my needs is a softraid. Disabled the fakeraid in the bios. Booted up the installer. It still loads the nvidia /dev/mapper driver. It still sees the drives as a fakeraid. Wiped out the drives using gparted. Booted up the installer. Still sees the drives as a single /dev/mapper/nvidia_lkjwer drive. Installed Ubuntu to see if I'm crazy, or if it's centOS. Ubuntu installed w/o a problem (on a single drive). Enabled, disabled, tweaked every freaking possible bios setting. Still sees the drives as a fakeraid.

I have recently installed CentOS on my server and I am trying to install a Teamspeak server as well as a web server using ISPConfig. But, for installing a Teamspeak server I wanted to create the user account "teamspeak" to run it so my files under root are not accessible for security reasons. I was wondering if there was a way of creating the user teamspeak with a disabled login, I know in Ubuntu to do this you do: adduser --disabled-login teamspeak

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?

I 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?

I have a file like this code...
I would like to use sed or similar to remove everything before the period, but only for the lines 1 and 3 (or lines with a-z.a-z and not a-z = 0-9.0-9.0-9.0-9)
I found a way to do this using:
cat $file | sed 's/[.].*//'
But this 1)remove all the text AFTER the period and not before it, and 2) removes everything after the first decimal of the IP address.

I installed linux 2010 mandriva on a (embeded) system,and i run several server programs on it that accept connections from clients. clients are connected to server(s) and every things is ok, but when i go to home and back to my work tomorrow, i see no data can be sent to server programs and this problem exists until i restart the server programs or reconnect tcp client programs. this problem occurs even when both client and server programs executed on the same (embeded) system.why this happens? i checked by netstat and see that server ports exists in the list(and not closed by kernel) but it seems kernel or an application above it prohibit data transmission.i changed the OS and installed ubuntu but the problem exists.
