  • How can I automate my Linux computer to power off (and on preferably) under certain circumstances?

    - by Ashimema
    OK, So a little background; I've been using Windows Home Server as a Backup Appliance, Media Server and Share Server at home for some time. I decided it was costing me allot of juice so very early on added the "Lights Out" add-on to ensure it was only running as and when needed. I'm now looking to switch to a Linux based server and I'm looking for a similar tool/set of tools for advanced power management. Now the question; Anyone got any all-in-one suggestions (i.e with client parts for both Windows and Linux and a server part for the Linux server), or can anyone simply verify that I'll need to set-up all the individual bits for this myself separately? (A tool similar to "[SmartPower][2]" but for linux would be a great start)

  • Can installing Linux or Grub make all of my operating systems slow?

    - by Geore Shg
    I installed Linux Mint 64-bit recently but it freezes up all the time. Not only that, but Grub wouldn't detect Windows. I thought it was just an issue with Linux Mint so I booted into Ubuntu - however that froze up as well. I downloaded Fedora to replace Linux Mint with, but that also freezes up. I finally gave up trying to repair Grub, burning a supergrub grub2 disk and using that to boot into Windows. Windows now freezes up as well. I installed a new copy of Windows on a different drive but to no avail. Right before all this started my computer was running very smoothly. I am wondering if the installation of Linux Mint, the reinstallation of Grub, or me messing with the BIOS (when I was attempting to repair Grub) could have done something drastic enough that everything is slow now? I realize that computers get gradually slower over time, but this was in no way gradual and it happened directly after the installation of Linux Mint. If so, what should I do?

  • New 64 bit linux system has regular processes (ps, grep etc) taking up way too much VIRT mem

    - by user42980
    We just moved from a 32-bit machine to a 64-bit machine. We have quickly ran out of memory despite the new boxes have twice as much ram as the old boxes. Running a simple ps command will illustrate the problem. New machine: 132 prod-Charlotte1-node1 ~/public_html/rearch/cgi-bin ps aux | grep ps root 293 0.0 0.0 0 0 ? S< May09 0:00 [kpsmoused] xamine 2267 1.0 0.0 63728 928 pts/3 R+ 16:50 0:00 ps aux xamine 2268 0.0 0.0 61172 752 pts/3 S+ 16:50 0:00 grep ps Old machine: 132 prod-116431-node1:/home/xamine ps aux | grep ps xamine 23191 0.0 0.0 2332 768 pts/6 R+ 15:41 0:00 ps aux xamine 23192 0.0 0.0 3668 692 pts/6 S+ 15:41 0:00 grep ps Notice that the ps process is using 63M of VIRT mem vs 2 on the old machine.

  • Run Windows in Ubuntu with VMware Player

    - by Matthew Guay
    Are you an enthusiast who loves their Ubuntu Linux experience but still needs to use Windows programs?  Here’s how you can get the full Windows experience on Ubuntu with the free VMware Player. Linux has become increasingly consumer friendly, but still, the wide majority of commercial software is only available for Windows and Macs.  Dual-booting between Windows and Linux has been a popular option for years, but this is a frustrating solution since you have to reboot into the other operating system each time you want to run a specific application.  With virtualization, you’ll never have to make this tradeoff.  VMware Player makes it quick and easy to install any edition of Windows in a virtual machine.  With VMware’s great integration tools, you can copy and paste between your Linux and Windows programs and even run native Windows applications side-by-side with Linux ones. Getting Started Download the latest version of VMware Player for Linux, and select either the 32-bit or 64-bit version, depending on your system.  VMware Player is a free download, but requires registration.  Sign in with your VMware account, or create a new one if you don’t already have one. VMware Player is fairly easy to install on Linux, but you will need to start out the installation from the terminal.  First, enter the following to make sure the installer is marked as executable, substituting version/build_number for the version number on the end of the file you downloaded. chmod +x ./VMware-Player-version/build_number.bundle Then, enter the following to start the install, again substituting your version number: gksudo bash ./VMware-Player-version/build_number.bundle You may have to enter your administrator password to start the installation, and then the VMware Player graphical installer will open.  Choose whether you want to check for product updates and submit usage data to VMware, and then proceed with the install as normal. VMware Player installed in only a few minutes in our tests, and was immediately ready to run, no reboot required.  You can now launch it from your Ubuntu menu: click Applications \ System Tools \ VMware Player. You’ll need to accept the license agreement the first time you run it. Welcome to VMware Player!  Now you can create new virtual machines and run pre-built ones on your Ubuntu desktop. Install Windows in VMware Player on Ubuntu Now that you’ve got VMware setup, it’s time to put it to work.  Click the Create a New Virtual Machine as above to start making a Windows virtual machine. In the dialog that opens, select your installer disk or ISO image file that you want to install Windows from.  In this example, we’re select a Windows 7 ISO.  VMware will automatically detect the operating system on the disk or image.  Click Next to continue. Enter your Windows product key, select the edition of Windows to install, and enter your name and password. You can leave the product key field blank and enter it later.  VMware will ask if you want to continue without a product key, so just click Yes to continue. Now enter a name for your virtual machine and select where you want to save it.  Note: This will take up at least 15Gb of space on your hard drive during the install, so make sure to save it on a drive with sufficient storage space. You can choose how large you want your virtual hard drive to be; the default is 40Gb, but you can choose a different size if you wish.  The entire amount will not be used up on your hard drive initially, but the virtual drive will increase in size up to your maximum as you add files.  Additionally, you can choose if you want the virtual disk stored as a single file or as multiple files.  You will see the best performance by keeping the virtual disk as one file, but the virtual machine will be more portable if it is broken into smaller files, so choose the option that will work best for your needs. Finally, review your settings, and if everything looks good, click Finish to create the virtual machine. VMware will take over now, and install Windows without any further input using its Easy Install.  This is one of VMware’s best features, and is the main reason we find it the easiest desktop virtualization solution to use.   Installing VMware Tools VMware Player doesn’t include the VMware Tools by default; instead, it automatically downloads them for the operating system you’re installing.  Once you’ve downloaded them, it will use those tools anytime you install that OS.  If this is your first Windows virtual machine to install, you may be prompted to download and install them while Windows is installing.  Click Download and Install so your Easy Install will finish successfully. VMware will then download and install the tools.  You may need to enter your administrative password to complete the install. Other than this, you can leave your Windows install unattended; VMware will get everything installed and running on its own. Our test setup took about 30 minutes, and when it was done we were greeted with the Windows desktop ready to use, complete with drivers and the VMware tools.  The only thing missing was the Aero glass feature.  VMware Player is supposed to support the Aero glass effects in virtual machines, and although this works every time when we use VMware Player on Windows, we could not get it to work in Linux.  Other than that, Windows is fully ready to use.  You can copy and paste text, images, or files between Ubuntu and Windows, or simply drag-and-drop files between the two. Unity Mode Using Windows in a window is awkward, and makes your Windows programs feel out of place and hard to use.  This is where Unity mode comes in.  Click Virtual Machine in VMware’s menu, and select Enter Unity. Your Windows desktop will now disappear, and you’ll see a new Windows menu underneath your Ubuntu menu.  This works the same as your Windows Start Menu, and you can open your Windows applications and files directly from it. By default, programs from Windows will have a colored border and a VMware badge in the corner.  You can turn this off from the VMware settings pane.  Click Virtual Machine in VMware’s menu and select Virtual Machine Settings.  Select Unity under the Options tab, and uncheck the Show borders and Show badges boxes if you don’t want them. Unity makes your Windows programs feel at home in Ubuntu.  Here we have Word 2010 and IE8 open beside the Ubuntu Help application.  Notice that the Windows applications show up in the taskbar on the bottom just like the Linux programs.  If you’re using the Compiz graphics effects in Ubuntu, your Windows programs will use them too, including the popular wobbly windows effect. You can switch back to running Windows inside VMware Player’s window by clicking the Exit Unity button in the VMware window. Now, whenever you want to run Windows applications in Linux, you can quickly launch it from VMware Player. Conclusion VMware Player is a great way to run Windows on your Linux computer.  It makes it extremely easy to get Windows installed and running, lets you run your Windows programs seamlessly alongside your Linux ones.  VMware products work great in our experience, and VMware Player on Linux was no exception.

  • Linux installation on Acer Aspire One D270

    - by ronnie
    I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that. Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270. Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage. I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not. Specs: RAM : 2Gb DDR3 Processor: Intel N2600(Cedar Trail) Graphics: Intel GMA 3600 HardDisk: 320Gb 5400 rpm

  • What has Ubuntu contributed to the Linux Kernel?

    - by Luis Alvarado
    This question is similar to this one: What unique enhancements and features has Ubuntu brought to the Linux Community but in this case it is directed towards what has Ubuntu contributed to the official Linux Kernel. For example, many times I hear about Intel contributing to patches for the Linux Kernel like the RC6 latest patches and any other related to the recent Sandy/Ivy Bridges. In another group, Android did an upstream patch and a lot of ARM patches have also come to the Linux Kernel. I have seeing only a small percent of companies and groups that have contributed to the Linux Kernel (http://kernel.org) but I want to know, since the beginning of Ubuntu till now, what has Ubuntu contributed to the Linux Kernel in regards to any aspect of the kernel. For Kernel information I typically go to http://kernelnewbies.org and http://kernel.org

  • Using EPEL repos with Oracle Linux

    - by wcoekaer
    There's a Fedora project called EPEL which hosts a set of additional packages that can be installed on top of various distributions such as Red Hat Enterprise Linux, CentOS, Scientific Linux and of course also Oracle Linux. These packages are not distributed by the distribution vendor and as such also not supported by the vendors (including Oracle) however for users that want to pick up some extras that are useful, it's very easy to do this. All you need to do is download the EPEL RPM from the website, install it on Oracle Linux 5 or Oracle Linux 6 and run yum install or yum search to get the packages. example : # wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm # rpm -ivh epel-release-6-5.noarch.rpm # yum repolist Loaded plugins: refresh-packagekit, rhnplugin repo id repo name status epel Extra Packages for Enterprise Linux 6 - x86_64 7,124 The folks that build these repositories are doing a great job at adding very useful packages. They are free, but also unsupported of course.

    Hello, I'm looking for a possibility to get the color of a pixel with given screen coordinates (x,y) in c++ / Linux? Maybe something similarly like getPixel() in Windows. I spent the whole day to find sth but without any success. Thanks, Stefan

  • Is there any WinSCP equivalent for linux?

    - by MiniQuark
    I love WinSCP for Windows. What are the best equivalent softwares for linux? I tried to use sshfs to mount the remote file system on my local machine, but it is not as user friendly as simply launching a GUI, plus it seems to require root access on the client machine, which is not very convenient. Of course command line tools such as scp are possible, but I am looking for a simple GUI. Thanks!
