General :: Changing The Power Supply Unit And The Distros?
May 3, 2010
I have installed on my computer Solaris10 (64bit version), PCBSD8 (64bit) on 2 primary partitions and 7 Linux distributions (Redhat,Debian,OpenSuse,Fedora,LinuxMint,Slackware,Ubuntu) on the extended partition. I know this might be a stupid question, but here it goes: I have a problem with my actual power supply unit (the fan doesn't work as it should) and I will change it soon. Is there a problem with any of the Linux distributions if I change my power supply unit? I mean, will the Linux operating systems work properly with a new power supply unit or do I have to reinstall all Linux distributions?
Does anyone had any experience with fanless, low-powered power supply units (PSUs)like PicoPSU? Please share your experience.
I am also interested to hear about experience concerning the fanless cooling solutions and/or power-scaling for low-end CPUs like Intel's Atom, AMD's Neo or Via's Nano.
come across with this issue for one server we are giving support please,help me to know why this issues occurs and alsothat i want a command to display power supplies for the server.please,let me know if anybody is familiar with these kind of issues.
I just recently installed Ubuntu and my power supply cooling fan won't power down normally when I would run windows tho it would power down after the system was finished starting up. How can I remedy this?
Is it technically possible to use just one power supply for more than one motherboard?The reason for asking is that I have a number of old (a few years) boards that I would like to use to make up a blender render farm yet only have one spare PSU. Having looked at the pin spec URL...pin 16 (power on) should only be connected to one board (or have a manual switch to ground for on)Pin 9 (standby +5v) probably should only connect to the one board or none and the other (or all) boards would need pin 9 to be tied to a +5v pin.All the boards would network boot and have nothing connected to them, no disks, floppies, monitors, etc; as all data would reside on a network server.
is this a good combination to use with 8 GB of RAM and 2.6 GHz AMD Hex core? The power supply will be replacing a 450 watt power supply and the video card will be replacing an ATI 5750 1 GB (Which currently doesn't work without 10.9, so far) The problem with these is that it doesn't meet the AMP rating of 38A of the GTX 470.
My pc had hardware malfunction; power supply interruption. At this moment it is working stable. My Windows 7 installation is ok but Ubuntu Maverick which I used during crush has malfunction. When I start to boot it looks like this: I had to make a foto so you all can see the problem. all my important files are stored on Ubuntu partition..
I have a 500GB WesternDigital Elements external harddrive and recently I plugged it into my computer and noticed the green light on the power adapter didn't light up anymore. I'm assuming that the power adapter failed - is this a fairly safe assumption? I know it COULD be something else, but does this at least make sense to move forward?Coincidentally, I've been researching new externals to order a 1.5TB because the 500GB is full.
I'm contemplating two options: 1.) Replace the power supply for ~$40 2.) Take apart the external and mount it internally
If it is in fact the power supply it might be the best option to just replace the thing and have 2 externals for backing up data on. But if it turns out to not be the power supply I'm out $40.I'm not sure how taking apart the external and install the hard drive in a desktop computer would be. Is the harddrive a standard drive? Does it have all the same power cords a normal computer would? If so, I could just install it into my brother's desktop and retreive the data that way (and he'll have an extra 500GB hdd).
My router/adsl modem is not connected to a power supply so when power goes and comes the network will do a re-boot. Now the problem is my OpenSUSE network won't come back on! I set the static ip as Autoeth0 to eth0 however when network updates I losse eth0. Why is this happening? Why doesn't the PC simply re-connect? Can I do it via command line?
So now that it's working the Server can't be seen from the internet. I see that the router changed all the ip address so I changed the fort port forwarding on the router and still not working. And the external ip address has not changed.
I currently have UNR dual booted with Win7 on my Netbook. I'm thinking about changing to another version of Linux (maybe Cruncheee) by overwriting the UNR partition with a different distribution.
My concern is that doing so will screw up grub. So I just wanted to make sure that if I got rid of the Linux partition I have now, there will still be a boot-loader in place on the computer.
I want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: The database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. DMA: Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it. Write-caching: When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it.
I have been looking for information on how to ensure these are so for CentOS and Ubuntu, but can't seem to find anything at all. I want to be able to check these things and change them if needed. The actual hardware involved is very modest. The point is to get the most out of what hardware we do have, even though it's "not very serious hardware" from a broader perspective.
I am looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps) with ARM-based processor. We use Eclipse IDE and C++ lanuage for development. Does anybody have recommendation for tools to analyze code complexity? The tools is better to support McCabe complexity metric, however, we may also consider others. Does anybody have recommendation for unit testing?
I have the following commande /sbin/fuser -f -u /u/DT01/F010107 1>/tmp/null 2>/tmp/seausr.T0069 when executing as root 'su' this give me all user using the file. but when tried with 'sudo' i am asked with 'user password'. Is ther anyway to simply get the result without having to supply a password and to see all user not only me. (i have the file open also).
When I was using Ubunutu 10, I updated the ATI drivers from their web site and the installation failed. There is no uninstall for it that actually works. So, very annoyed, I switched to the VESA driver by editing xorg.conf as shown below.
I just upgraded from Ubuntu 10 to 11.04 and when it booted up it told me that I do not have hardware to run the Unity desktop. Even on a restart the login menu shows the selected desktop as "Ubuntu" (no classic or anything though my desktop looks just like it did in Ubuntu 10).
After upgrading to Ubuntu 11 it seems to have switched to a proprietary ATI graphics driver which actually seems to work very well. Except, no Unity desktop.
If I click System, Administration, Additional drivers it shows one driver and says that it is enabled and in use. The driver is "ATI/AMD proprietary FGLRX graphics driver" and in the description it says "3D-accelerated proprietary graphics driver for ATI cards".
Is there a way to explicitly turn on Unity or ask it why it doesnt want to run?
lspci | grep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc Redwood [Radeon HD 5670] $ /usr/lib/nux/unity_support_test -p Segmentation fault
I do not really care which driver I use. I have been told there is a new driver included in Ubuntu 11 that supports my video card. Is that the driver I listed above or is thee another that I can activate somehow. What shall I do? I just want Unity to work.
Try disable this driver? Will it automatically pick up some default? Do I have to delete or do something to xorg.conf as well?
Is there a way to tell Ubuntu "forget whatever video card driver or configuration is in place and go back to the default for a new install"? I have tried "dpkg-reconfigure xserver-xorg" but all it does is ask for a password and then does nothing. Everyone says to run this buts its never done anything for me.
/etc/X11$ cat xorg.conf Section "Device" Identifier"Configured Video Device" Driver"vesa"
I'm wondering what the least err unit/ units are for a working Linux. For instance. Is a kernel + a window manager enough? Then let's say you install one app on top of that - now you have one app you can use, right? But is that right (kernel + window manager)? Do you even need a window manager for a functioning system? Do you need more than the window manager?I'm asking because I'm fixing to build something from the ground up but it isn't a regular Linux thing and I want to approach if from the direction of adding just what I need not taking away what I don't.
We're seeing NFS hangs with a Fedora 13 client to a Thecus N7700 NAS unit. /etc/fstab entry for the mount is pure default. Sometimes, the hang ups freeze the Fedora client and it has to be power-cycled to reboot it.
I'm working on program that is going through setting different baud rates onto a config file. After I set a new value i want to check if it's the correct one by reading from the serial port on the server unit. I know what to expect if it's the correct baud rate so that's no problem, but searching through the internett i've yet to find a compact solution to my problem.
I currently have one very big partition in my laptop that runs Ubuntu. I have to install Fedora for work and I'd also like to try out OpenSUSE, so I'll have to repartition. Since I don't want to duplicate data, I will move /home to a different partition and mount it from all three. I'd like to know, can I also do this with /var and /usr? If so, would that mean that every program I install will be available from all three?
i have linux mint 10 installed on my system and i want to install fedora 14 too .since fedora 14 comes with grub legacy and not grub 2 so,if i install fedora 14 would the grub 2 that comes with Linux mint be over-written by grub leagacy if yes,then how do i install fedora 14 withoust losing grub 2
i am still a linux newbie. i'm trying to study the features of the different LINUX distros through installing ubuntu,debian,redhat,centos and fedora as Virtual Machines in VirtualBox.As i've figured out, they look different somehow, they have diffirent managers ,i.e. for downloading or updating their components. BUT MY QUESTION: are these distros internally compatible ?
Do any commands exist in one distro but not in the others? ARE ALL Distros compatible on the CLI-basis ?
I will be staying at a hotel for a couple weeks that has a wired internet connection to each room. I have a Linksys WRT54G v6 wireless router and would take with me and set it up so I would have wireless in my room.
The upstream provider is supplying samba3x (currently samba 3.3.8) packages in their supplementary repository. I know that most of what is in the supplementary repository is burdened with restrictive or non-free licenses, however, Samba is not.
The samba3x packages are critical for Windows Server 2008 trust relationships as well as Windows 7 client support for a CentOS server acting as a Windows domain controller. I know that I can either roll my own packages or compile from source, but an officially supported version would be a much better option on a production server.Is there any way CentOS can "officially" supply these packages and their associated dependencies?
Are there any other Linux distros (apart from Ubuntu) which allow you to install 'on' Windows?I'm having problems installing Ubuntu on my Thinkpad, it keeps breaking down halfway during the installation. I wanted to try another.I wanted to try and use fedora KDE but it doesnt appear to have the 'windows' installation version?
A friend of mine is working at a company that's getting a lot of netbooks. None of them have optical drives so USB is important. They are going to switch most of the netbooks from Windows XP to Linux. I told him that both Ubuntu and Ubuntu Netbook Remix can be used this way. He installed both to a USB Drive and what he likes is at bootup it gives the option to either run it from USB as a Live Distribution or to install it to the hard drive.
The installation would give him a way of switching them to Linux and in other cases for users who prefer Windows XP they still have the option of using a USB Flash Drive when they want to use Linux. The question: What other distributions work this way? I have looked at Fedora, CentOS, Mandriva, and OpenSUSE. Would either of these install from USB or even work as a Live Distribution from USB or even do both? Are there other distributions that would do this?
