Ubuntu Servers :: Shut Off LCD On Laptop Server
Jul 20, 2010
I've just installed Ubuntu Server 10.04 on an old laptop. I would like the screen to automatically shut off after, say, a minute of inactivity.
- After some time, the monitor blanks but the backlight does not power down.
- I do not have a gui installed, and do not want to install one since this is a server. Most of the solutions I've found involve running X or KDE.
- It's an old laptop and the lid switch is broken, so closing the lid won't work.

Offlate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70
3072 MB 800 MHz SDRAM
I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.

I am running a local webserver mainly for development. I have everything set up. The issue I currently have is that I cannot shut down the machine from the command line. I can issue the command but the machine remains on. I also cannot get to the desktop via VNC.The reason for this, is that there is no monitor attached so Ubuntu says that it is trying to run in Low Graphics Mode. I found this out as I plugged the monitor in to my server.So question is, how do I get around this? How can I set up Ubuntu to get past this, or do I need to install Ubuntu Server?

Recently I built a new computer, making my old laptop redundant, so I thought I'd turn it into a portable studio computer with linux. I'm running Ubuntu 9.04 with the low latency kernal and the ubuntustudio audio packages. And while the system still has many other kinks I need to work out, my main issue is heat. Even when I'm running the official Ubuntu kernal rather than real-time one, I'll use the laptop for basic browsing and messaging.
Suddenly Ubuntu crashes with a warning saying that my laptop is too hot and has to shut down. The only way I've found around this is to run the laptop from cold with an external fan blow right onto the computer. I can still hear the fan working and airflow is totally unrestricted. If it helps, the laptop is 4 years old and is a Acer Ferrari 4000. I never had these issues running XP on it for the past 3 1/2 years and I'm relatively new to running a Linux system.

I am using debian testing on my office pc, but i need to access it's desktop from time to time. So i need No machine/teamviewer software that can provide me with possibility to interact my desktop. The problem is, that i want to run shadowed session type, because teamviewer is not good for me. So, when i run no machine in shadowed mode, it crashes with message "The connection with remote server was shut down, please check your network settings and try again." The log is here:

I've got a Lenovo Thinkpad X201i. The problem I have is (since I've installed Xubuntu) every time I start up my laptop it just hangs with a little flashing white stripe in the top of the left corner (like every start up). Then when I shut down the laptop using the power button and start it up again it works. How can this be possible? On start up, it hangs, while on the restart it always works. Which means I have to restart my laptop every single time.

I'm running Ubuntu 10.04 server as a guest on a Windows 7 host using VirtualBox. I've set the VirtualBox configuration to use a Bridged network connection so that I can access the internet through the Ubuntu guest and to access the Ubuntu apache server through my Windows host.This is all running on my laptop which connects to various routers using dhcp (some ip addresses start with 198. while others start with 10.) What I need is a single static ip address (or hostname/url) to setup my cms (drupal).how I can accomplish this given the varying routers the laptop connects to?

I purchased a macbook (for cheap) without a hard drive and decided to go with Ubuntu 10.10 on my new drive.
This laptop has serious overheating issues. I installed the sensor applet and the fans are not coming on, even when the core temp exceeds 167(f). The base of the laptop becomes hot enough to fry an egg on.
I'd like to find a way to make the fans come on in an automated fashion (without having to do it at the command line each time I want them to come on). I'd even be happy with them on all the time if that will resolve the issue, as the laptop overheats until shut down / freeze every time I use it.

I have an ubuntu fileserver and an ubuntu laptop both running 10.10.For some reason I can't connect to the server (file or remote terminal) from the laptop, even though I can access ssh through terminal on my mac and have been able to mount the filesystem on another computer running the ubuntu liveCD. I just get the error 'no route to host'.I've tried turning off the firewall on the laptop and re-installing ssh on both computers, but I don't have a clue what to do next!

Ubuntu was working perfectly fine, then I used the Update Manager to update ubuntu, but my laptop randomly shut down during the installation (which my laptop has never done before and hasnt done since). When I turned the laptop back on, and booted Ubuntu, a white box appears in the middle of the screen but rather than asking for my login details, it just says what I named my computer. I am unable to move my mouse or type anything on my keyboard at this stage..

I like to end my X session in Arch on a regular basis. I always use'killall xinit'..This gives a lot of WARNING's and ERROR's. Among the messages are some lines about syntax errors in my config files, I think. But mostly it's about a "Fatal IO error" and gnome-settings-daemon not knowing what session it is in.Is there a gentler way to put X down? Or is this how it should be?I tried killing some of the processes that claim to be interrupted, before killing X, to no avail.

There is a server which was installed 3 days back. It got Cent OS 5.4 64 Bit with 4 GB RAM. Apache, MySQL, PHP and vsFTPd were installed using yum.Server was on the network and approx 100 visitors were on the website. All of sudden server got down. It stopping responding ping. Server guys told that server got down and after a request submission, they restarted server. However reason of the problem is still unknown. I logged in to shell via SSH and checked /var/log/messages file, but didn't find any record which indicate cause of system shutdown. However dates in this file aren't in chronological order.
Is there any way or log file to check for the exact reason, why system got down. One reason could be hardware fault (for that I am going to ask hosting company to run diagnostics). Other reason could be a software/os bug. Is there any tool / log file to check and diagnose the cause.

I just installed LXDE and configured the .xinitrc file and when I gave the command "startx" and it tried to start, but stopped with this error message
Waiting for X server to shut down error setting MTRR
(base = 0xf0000000, size = 0x04000000, type = 1) Inappropriate ioctl for device (25)
I am not sure if I configured the .xinitrc file correctly, so that may be the problem.

I have a server 192.168.1.14 (I will call it 14) it runs Ubuntu server 10.04 and I have my Ubuntu Laptop 192.168.1.3 ( I will call it 3) that runs Ubuntu 10.10. I need to find a way to add users from my Laptop (user X) or a Windows machine user (Y). What I am trying to accomplish is to have file permissions some for Y only and some for X only and some for a group that contains X and Y. Now I have a Dir, on the server 14, with the owner Z (server user) and I gave it permission 760. Now my user X, from Laptop 3, (they have the same name in real life) is not able to access those files on a NFS share.
I would like to have the 760 perm and be able to access those files without doing a 777. I am thinking to add all users (XYZ)to a group and give read permissions for the group. My dilemma comes when the users are on different machines. I already created equal users on server with the same name but it does not do the trick. When connecting to server from 3 I can't access files that are owner by the group where user Z belongs (even if user X has the same name and password). I am thinking there has to be a deeper way of identifying users.

I am currently finalizing a SSH Tunnel (gSTM) via Ubuntu Server (see: [URL]). The gentleman who helped me there went above and beyond the call of duty as we used to say in the military. Accordingly, I wanted to start a new thread to explore options to the pending completion. So, several systems in play here. I will list two of the three with the presumption that the SSH situation is in play (testing it today from outside of my network).
Systems Currently in Play: Ubuntu 10.04 Desktop Edition with all updates as of today's post: Server: Acer Aspire AST180-400A. It is currently being accessed from Ubuntu 10.04 Desktop Edition with all updates as of today's post from a laptop: Toshiba Satellite A200. Router: Netgear N300 WNR 2000v2. Modem is Motorola Netopia 2210-02-1006. Proposed System To Add: eMachine ET1331G-05w running Windows 7. Why? Well, my girlfriend is terrified to ditch the Bill Hates way of things. It is running through the router currently as well.
What I would like to be able to do is access the Windows 7 desktop via my laptop on the road as well. Specifically, I need to be able to access and view documents and photos. Now, the docs are at least in OpenOffice; she switched to it finally. I would like to also be able to view my desktop to access docs and pictures on the server, but that may be a new thread as the Win7 situation is the priority right now.

I connect my laptop to several different networks and need to print in each of them when I am connected there. In the past (ie 12.2 and earlier) I solved this by running a cups server on the laptop and having it poll the appropriate cups servers in each network.
I was thinking that perhaps in 13.0 I could bypass having the cups server on the laptop and that KDE would "see" the various cups servers available. However this does not seem to work...

I try to make a small AVR-Board boot a Linux from my Lenovo laptop, which is configured as NFS server (running nfs-kernel-server). Everything is configured correctly and it should work, but it doesn't.I just installed another laptop (from ASUS) with the same configuration (OS, tools, settings) and there it works immediately.
So I wondered, what's going on on eth0 ? I checked with Wireshark and here are the things I found out.On both laptops, the following paket arrives:

I've checked the forums for a guide to sharing my printer with a laptop and cannot find any entries that are specific to my configuration. [URl]... My printer is connected to a desktop running Fedora 13. I also have a laptop running Windows 7. There was one web entry that spoke about "Windows Vista 7" that didn't match my configuration. [URL].. Is there a "how to" out there that I can follow to make this work? I am not a well-experienced user, so the more detailed (and accurate) the steps, the better!

I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'
From: [url]
I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?

I own a rather large website/forum devoted to Scuba utilizing vBulletin. The problem is that its become INCREDIBLY slow as of late. I have three Ubuntu web servers under a single Ubuntu load balancer and they draw from a CentOS 5 DB server running MYSQL. Here are my concerns:
-I am thinking that they are all 32 bit rather than 64 bit.
-I am thinking that the problem is an IO issue.

this may seem a little odd, but I used my server to install Ubuntu on to an external hard drive. (long story short, the server won't recognize any internal hard disks with any type of video card installed. The video card works just fine when installed, and it will read both CDs/DVDs and USB drives just fine, it just refuses to even notice hard disks. I'm assuming an IRQ issue, but I've tried changing them with no success.) Having installed Ubuntu 10.04 on my external 250g hard disk, I attempted to boot it from the USB drive, since the system has that option. It tells me "error: out of disk" and goes to the Grub rescue prompt. Having followed multiple threads and advice posts, including on this forum, I was unable to resolve the issue. For s'n'gs, I hooked affore mentioned external hard disk to my laptop and tested it. Boots just fine. Then hooked it back to my server to see if it would boot. Still no dice [Just a side note, no the video card is not currently installed in said server, I was testing it to see if the thing would install and operate alright before I tested it with video card installed. Only ever make one change at a time, that way if something explodes, I know what caused it.] My initial objective was to get an operating system that would boot with the video card installed. Any ideas what might be going wrong here?
