We have a quad core Intel Xeon E 5410 processor running on recently installed centOS 5.5. Machine can't be pinged all of sudden and when we switch on the monitor, no signal on it, even no response on keyboard. We thought the problem accorded with abrupt temperature changes, is it so? But we have similar machines running efficiently under same temperature conditions.

I've got a box with a fresh installation of CentOS 5.6, but had several configs copied from an old 4.8 box that I've now got to finish. Most everything seems fine, but I can't get apache running. It reports that it starts up fine, but immediately stops and reports "httpd dead but subsys locked"Most of the advice I've found while searching suggests to just delete the http.pid file and restart, which doesn't help in my case. I did find a few problems where SELinux was restricting httpd from creating or touching certain files (I found reports in /var/log/messages) but I've worked through that.
So the big question here is: /var/log/messages and /var/log/httpd/error_log are now empty, and don't show any more errors when I restart httpd. Does anyone know where else I can look for reporting/logging on what's happening to httpd to cause it to die?
I've just set up Mint Linux 9 (Isadora) on my laptop (Compaq R4000), and I'm having an issue with 'dead space' when using a second monitor. Because the aspect ratios on the two monitors I'm using are different (the laptop is widescreen, the other isn't) I'm getting dead space above (or below, depending on its positioning in the virtual desktop) where the mouse will hide. It's not a huge problem, but it's bugging me like nothing else.
Is there a convenient work-around for this problem?
Ok, first off I installed the disc after having to holed select for the language to come up then selected the nomodeset option before installing, then I installed, restarted and got no signal. After that I tried to edit the grub like a thread said by changing splash or whatever to nomodeset and it won't allow me to edit.
View 2 Replies View RelatedI use my old computer as an NAS, so I remove the monitor after I installed linux on it (disconnect vga cable). I use ssh to control the machine and it works fine. Until some day, after kernel/softare upgrade or messing up some configs, I cannot connect to it through ssh, then I have to plug the monitor back, but the monitor says "No input signal". So I have to restart the computer WITH the monitor connected, and the monitor's back!
I think the computer/linux kernel doesn't detect the monitor plug-in event. So how can I start my linux box without a monitor, but when it goes wrong I can still plug my monitor (vga) back and use the console.
Edit: just one pci-e video card, has dvi, vga, tv/out (s-video)
Edit2: Xorg is not running. I just need the console (CTRL+ALT+F1). The problem is, if the machine booted without a monitor connected, it won't give me a pseudo terminal after I attach the vga cable while it's running. Clearly the monitor is not auto detected as usb device. I'm wondering how to let the monitor auto detected.
how can i view/monitor what a user is typing in other terminals in centos?
View 1 Replies View RelatedI am running on ubuntu 10.04 and using the latest nvidia driver. What I experience is a random black screen, my monitor goes dead and won't turn back on till I hardboot. I had this issue on windows and solved it by downloading rivatuner and telling it to force my 9700m into staying in 3d performance mode at all times. I know it has nothing to do with temps or anything like that. All I need to know is how I can duplicate what I did with rivatuner on windows
View 1 Replies View RelatedIf I turn off the monitors, I get a black screen (the monitors goes to power save) when I turn them on again.
I have a workaround which involves pressing ctrl-alt and f3 and then ctrl-alt f7. That usually works and brings up the graphical login-screen. And I get my session back.
But sometimes when I log in, my session is gone. It is as if I was logged out or the system has rebooted.
I have two monitors and Nvidia.
I basically destroyed my laptop a couple of years ago. Windows XP wouldn't even start but it didn't come with an installation disk. I tried recovering it but it just died. So a few months ago I put a box of thing on top of it which broke the screen! I was going to chuck it out until I stumbled upon a page which told you you could use it as a web server.
I decided to use it to host my website. I installed ubuntu without a problem however it wasn't until I was about to start it up I found out it was against BT's terms and conditions!! So since I installed ubuntu I thought I might as well make use of it and use it to render my files. When I went to turn it on for the second time and plugged it into the monitor it said input signal out of range!
I can see the login screen but I can't move the mouse or anything. I can't access the terminal, how can fix this?
I am facing weired problem while installing Ubuntu 8.04 on my desktop
specification of it
Intel Core 2 duo 2.93
4 GB RAM
500 GB HDD
Intel Motherboard DG41 RQ
it goes on loading ubuntu and then after when i am suppose to get my home screen with bird background to view, monitor stops getting signal.
i tried both 32 bit and 64 bit
ubuntu-8.04.3-desktop-amd64.iso
ubuntu-8.04.3-desktop-i386.iso
but no luck where as 9.10 works like a charm and i have no issue in working with it.
but because of some external H/W drievrs i need to stick to old karnel version which supports 2.6.30 or lower
I have an Acer Aspire 6930g with an nVidia GeForce 9300m GS which has a broken screen. I have been using an external monitor for some time using Linux Mint, without issue.
I initially set this up with great difficulty using the small parts of the screen that would still display an image at the time. Now, however the screen is totally dead, I have since disconnected the laptop monitor in order to not cause issues.
The issue I am currently having is trying to use live distros.
I'll give you example: I boot ubuntu 9.10 32bit and it gets to the initial boot menu. I choose "Try Ubuntu..." It shows the loading screen. Screen goes blank when going to desktop
I tried Ctrl+Alt+F1 to get to a terminal, but the screen stays blank. The same thing happens with both Knoppix and Backtrack 4 as well. The display goes blank upon switching to the desktop.
I'm trying to install Fedora 10. I'm booting from a CD, and the installation gets as far as those 3 progress bars in the very beginning. As soon as they all load, my monitor goes black and starts flashing a "DVI Input Out Of Range" warning. That's all.
I'm using a
nvidia geforce 8800 gtx
and the Planar PX3611W monitor.
I usually log out from my account, let the pc working and close the monitor. When after some hours I try to open again the monitor I get the msg "No Signal" I move the mouse I press some buttons at the keyboard but nothing.. I have to reboot again to see the monitor working.. What can I do?
View 7 Replies View RelatedSo my computer works reasonably fast running XP (old 3GHz processor with 512RAM), but every so often it simply freezes. I've tried all I can to fix this, but sometimes when I boot up XP it'll get to the window's logo then freeze, sometimes it'll get all the way to the desktop and then freeze, and sometimes it'll start up, run fine for an hour or two then freeze. By freeze, I mean the screen doesn't update, the keyboard and mouse do nothing. Updating NVIDIA drivers doesn't seem to help - some make it worse! So I've had enough, and decided to download Wubi to try Ubuntu on it. I'm not ready to remove windows just yet (lots of data on this machine) and so I don't really want to try dual-booting yet.
Wubi downloads and runs in Windows fine. When I go to restart, after picking Ubuntu from the menu it shows a little text (I think about installation, and press Esc for menu) then my monitor gives a "No Signal" message. So I try restarting (pressing the button), and pressing Esc to bring up the menu. I tried all 5ish options, and "Safe graphics mode" and "ACPI workarounds" seem to last longer, but the same error occurs, before it has even prompted me (still doing its own thing). So I can get up to GRUB, and even get into the grub> prompt. I tried adding irqpoll and/or all_generic_ide to the boot thing (pressing e in the grub menu), but that hasn't helped. I'm unsure of how to find what hardware my computer has (only computer, don't have receipt), but I know "NVIDIA GeForce 6600 GT".
I am looking for a tool that can monitor my 3g signal.
View 6 Replies View RelatedI did a fresh install of Lucid Lynx, and now when I start up it shows a blinking cursor for a second or so and then my monitor shows an "Input signal out of range" error. The same thing has happened before, and I was able to fix it by editing the boot options in grub to include 'nomodeset'. However, this time the usual grub loading screen where I would normally press esc to edit the boot options doesn't appear. (Spamming esc doesn't seem to work either.) If it matters (which I have an odd feeling that it does) I partitioned the hard drive into an ext4 partition that mounts at / , a swap partition, and another ext4 partition that mounts at /home . I attached a screenshot of what GParted says about it.
View 2 Replies View RelatedI have this issue with two different computers. One is a dell optiplex gx60 and the other a hp pavilion a317x. The two monitors are a hp pavilion f70 and a nec mulitsync lcd.
The problem I have is the monitor will randomly turn off like it would if the signal is lost but the computer is still running. I cannot get the monitor back on unless I do a hard shutdown and reboot. Sometimes it will happen within minutes of turning on the computer and sometimes it will take hours or days. I have had this problem with ubuntu 10.04 which is currently installed, mint 9 xfce, and mint 9 fluxbox. The only distro that it did not do this on was peppermint ice and windows xp.
I don't know at this point if it is hardware or software related. I am new to linux so I don't know what else to look for.
I am running 11.04 on a new Gateway with 8 gigs of ram. It is a solo installation. The monitor is connected via an HDMI cable. Everything was great (installation running smoothly for over a month) until last night. I just installed a netgear router and was setting it up with the system to try to get Stanza on my IPAD to connect to Calibre. Anyway, i suffered a severe freeze up warranting a hard boot. I could see the drive working, ancillary drives lit up, keyboard lit up so I know the system is working. The monitor did not come on, It shows a yellow light indication no signal. It is a 28" Hansspree. I tested the monitor by hooking it to a laptop. The monitor is fine. I cannot see anything on the screen so I can't boot to repair mode or use a CD. There is no signal.

(somehow I knew that something is going to go wrong), and now my PC starts, works fine for a few seconds, then I get a black screen for a moment, and then my monitor starts acting like PC is off.Interestingly I think that otherwise everything is working just fine and that I just can't see anything due to the black screen (monitor is flashing like there is no signal coming from PC).

When you need to change something on the server you can hook up a monitor and a keyboard and do it through the console.
I would like to hook up an external monitor in this fashion for a desktop. The current video card can only support a single display. So I was hoping there was someway to use a second monitor as just a permanent console since simple text shouldn't require a video card?
I'm wondering a couple of things about my LAMP stacks:
1) How do I get a list of all the network cards installed in a linux box? I've run this command and it shows 2 network cards which is probably all of them:
Code:
mii-tool -v
2) How can I check the percent utilization of a given network card? I.e., at any given time, what linux command will tell me the how much of a network card's bandwidth is being consumed? I've checked both ethtool and mii-tool and I don't really see any helpful stats.
3) How can I make sure that a linux box will optimally use both network cards? I'm a bit fuzzy on how IP addresses and network cards and hostnames work together.
I need a software to monitor all USB activities over the network from a red hat server with alert notification i have searched a lot and never found a thing

View 1 Replies View Relatedbut I think I have a reasonable handle on the /etc/init.d, /sbin/service, chkconfig, and runlevels stuff under CentOS. However, when I install particular daemons (not part of CentOS distro), I get a weird issue. If I log in as root and do /sbin/service <daemon> status, it says "... is running...", however, if I log in as a non su, and do the same /sbin/service ... status, it says "xxx dead but subsys locked." Is the daemon running or not? I assume it's some kind of privilege issue with how the daemon is setup versus the non root login.I would like to have users be able to use service to query daemon status as works with the base daemons like sshd and httpd.
