    - by PeanutsMonkey
    I am in the possession of a HP laptop specifically the HP Folio Ultrabook. I need to make an image of the harddrive so that in the event it needs to be restored I can do so with the base operating system which is Windows 7 Professional as well as the HP recovery partition. I also need to backup all data that is on the laptop. Where do I start? What software can I use? Please limit these to freely available software or Linux I need to be able to backup the image to a file server and an external harddrive Is there anything else I need to do or know? The laptop is being used by a user on a domain

  • Problem with wake after suspend using USB remote.

    - by Bod
    Hi, I'm a linux newbie looking for some help. I'm currently setting up an XBMC HTPC using a laptop and 10.10 and all works great except for waking from resume using the power button on the remote. The suspend works from remote works fine as does the resume using the power button on the laptop. I've checked /proc/acpi/wakeup which initially showed the following. Device S-state Status Sysfs node C096 S5 *disabled pci:0000:00:1e.0 C0F1 S3 *disabled pci:0000:00:1d.0 C0F8 S3 *disabled pci:0000:00:1d.1 C0F9 S3 *disabled pci:0000:00:1d.2 C0FA S3 *disabled pci:0000:00:1d.3 C0FB S3 *disabled pci:0000:00:1d.7 C102 S5 *disabled pci:0000:00:1c.0 C22B S5 *disabled pci:0000:08:00.0 C115 S5 *disabled pci:0000:00:1c.2 C22C S5 *disabled C118 S5 *disabled pci:0000:00:1c.3 C22C S5 *disabled I've since configured the above so that the S3 devices above are enabled. I've confirmed that they are the correct devices using lspci 00:1d.0 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation N10/ICH 7 Family USB2 EHCI Controller (rev 01) None of this has worked unfortunately and I'm now stuck. It simply refuses to wakeup from the remote. The USB receiver shows no activity LED while suspended. Suspend/resume from the remote works fine from Windows 7 so I know the laptop is ok with it. Any ideas? I need to get this sorted to gain Wife Approval for this system. Thanks, Bod.

  • Installing VirtIO drivers in Windows Server 2008

    - by Stefan K.
    We are running a Windows Server 2008 system as a "guest" on a Linux-KVM virtual server (SLES11, with VirtIO support). We have trouble with the system performance and this is possibly due to not using the VirtIO drivers. I don't have much experience with neither KVM not VirtIO. Just heard it this could be the reason for our problem. Questions: The install examples I just found are describing how to install the drivers during Windows setup. Is it possible to install the VirtIO drivers later? We have running software on that system and would like to avoid reinstalling/setup of all these. I already found a page describing how to sign the drivers, which seems to be needed. A good tutorial page (step by step instructions) would be nice. Is there anything like that out there?

  • Only one user can connect to Ubuntu samba server

    - by StaticMethod
    I setup a samba server on 12.04 LTS, and it works great for one user but not the others. I am trying to map a network drive from a windows 7 laptop. I can successfully authenticate with one user, but the other two both get "Access is denied" errors. Here is my smb.conf file.

  • FOSS Development: Who develops the OS-specific packages?

    - by achristi
    I have a couple of FOSS projects. They can be a bit of a pain to get running unless you've got dependencies in place already, which I figure is par for the course for FOSS projects. We know that each free operating system out there has its own package management systems. A few of them, such as homebrew on Mac OS or AUR on Arch linux are very friendly to community contributions. What I am wondering is, who exactly is expected to contribute packages? Primarily I am concerned with the case of small or developing projects, since it's pretty standard for the big projects to be put in there by the OS maintainers. From my perspective, it is something of a chicken-egg problem, because your software will not make its way into a package system if it does not have users, and it is less likely to gain users if it is not easy to install and use. For the sake of discussion, let's assume that the software in question is actually legitimately useful. I can see where people could create crapware or spam and that should obviously be kept out of any package system. So, in summary, whose job is this? Is it spammy for a FOSS software dev to put his own work into various OS package repositories?

  • How to add display resolution fo an LCD in Ubuntu 12.04? xrandr problem

    - by SeregaI
    I am fresh for Ubuntu and Linux in general. I have installed Ubuntu 12.04 and stuck trying to setup correct resolution for my LCD display. The native resolution for the LCD is 1920x1080 here is the output from xrandr: $xrandr Screen 0: minimum 320 x 200, current 1280 x 720, maximum 4096 x 4096 LVDS1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x720 60.0*+ 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) Then I create new modeline: $ cvt 1920 1080 60 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync So far so good. then I create new mode using xrandr: $ xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync But for some reason that new mode was created for VGA (VGA1) output instead of LCD output (LVDS1): $ xrandr Screen 0: minimum 320 x 200, current 1280 x 720, maximum 4096 x 4096 LVDS1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x720 60.0*+ 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) 1920x1080_60.00 (0xbc) 173.0MHz <---------- ????!!!!!! h: width 1920 start 2048 end 2248 total 2576 skew 0 clock 67.2KHz v: height 1080 start 1083 end 1088 total 1120 clock 60.0Hz So, if I try to add mode to LVDS1, I get an error: $ xrandr --addmode LVDS1 "1920x1080_60.00" X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 149 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 25 Current serial number in output stream: 26 Adding that new mode to VGA1 works fine, but I don't use that VGA1 output.

  • Advanced command line editing for Windows?

    - by Ben Collins
    I'm developer who was "born and bred" on Linux and BSD systems, and I've become accustomed to having advanced tools for the console (posix shells like bash, for example). My career has taken a twist that means I'm working in a Windows environment most of the time, and the console capabilities are really poor by comparison. The traditional windows console environment is a complete joke, and even most of the third party attempts at improving things aren't a lot better. PowerShell is a huge step in the right direction, but the console applications themselves are still way behind where unix has been for 20 years. Does anyone know of a PowerShell console application that supports advanced command line editing like posix shells do? I'm particularly interested in emacs-mode editing, and I'd also like to be able to resize my window to an arbirary size, unlike the native console app that comes with Windows.

  • What version of Ubuntu to use for Desktop with 8Gb RAM?

    - by Alexander
    This may sound as a stupid question, but I am really interested whether Ubuntu Desktop i386 will be able to use all my available RAM. I want to use the latest, non-LTS version, 10.10. It says on the website that it's (i386) the Recommended version. I also recall that Flash Player had issues with 64 bit Linux. Also, the 64 bit version is listed in the Universal USB Installer as amd64. Does this mean that it's using instruction sets specific to AMD CPUs? (I have an Intel) Will it work fine with Intel? So which one to download and install? What to do to be able to use 8Gb of RAM?

  • Laptop keyboard and touchpad disabled on startup

    - by JAM
    I use Ubuntu 14.04 LTS on my Toshiba Satellite L775D laptop. 14.04 is the only operating system installed. I am new to Linux and only barely scratching the surface of doing things in terminal. When I boot my laptop keyboard and touchpad are disabled (99.99% of the time) if I do nothing. The only direct effect I can have is to keep pressing the "numlock" key during boot when I notice the "numlock" light goes off. If I do this then I have a 95% chance of the keyboard and touchpad working when I am in the operating system. I am able to use my wireless mouse regardless. I have not seen any messages during boot. Previously I have tried playing with input method settings and utilities as well as language support settings. This same problem exists with the 12.... and 13... versions of ubuntu. With everything I have tried (from looking at other posts/suggestions) it seems I can have only a temporary effect. Please help me find a permanent solution to this problem. thank you.

  • Red Hat 5.4 slow processing

    - by yucefrizk
    I'm running Red Hat Linux 5.4 on HP DL580 server with 16 processors and 64 GB of RAM. I'm connecting to the server remotely through SSH. after entering the password, it takes time to return the command line, if I click ctrl+c during this time, I'll have the command line prompt but not the correct bash prompt (I have to run bash to pass to my correct prompt). I tried to install Apache on the server, ./configure took 4 hours to finish instead of 1 or two minutes, Oracle installation same behavior. Server Disks are mirrored using RAID controller. any idea what could be the reason of this slowness?

  • Cannot install ia32-lib package

    - by A British Person
    I have several programs that reuquire 32 bit packages (pointing to the ia32-lib package). However, when I try to install it, this happens. spirit@ubuntu:~$ sudo apt-get install ia32-libs Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-multiarch but it is not installable E: Unable to correct problems, you have held broken packages. No big whoop, packages die all the time. I tried a month later however and I still got this error, trying to install the specific package produces this error. spirit@ubuntu:~$ sudo apt-get install ia32-libs-multiarch Reading package lists... Done Building dependency tree Reading state information... Done Package ia32-libs-multiarch is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'ia32-libs-multiarch' has no installation candidate I am no Linux whizz-kid, but this seems to be that the package doesn't exist. I searched for Skype in the software centre (I was told this installs the 32-bit packages) and it does not appear in the software centre, and the downloadable from their website produces an error about - funnily enough - no 32-bit packages. Anyone who helps me will get a medal from the gods with the weight of a thousand planets. Just don't wear it for god's sake.

  • Locking down firmware to keep stolen laptop from being formatted?

    - by Matt Ridge
    On the Mac laptops there are ways through the terminal to lock down the computer so that if someone tries to format the computer they won't be able to do it without the password. This way locks down the firmware. Is there a universal way to do the same thing on a PC? I know there are brands out there such as Samsung, Dell, etc that utilize different fimware types, and in turn will mean that their firmware will be locked down differently. That being said is there a "command code" that will allow you to lock the firmware to keep theives from formatting the hard drive and wiping out your data? I know a person who has time, and knowledge can get any password, and hopefully the person is smart enough to use another password to lock down the firmware, but that's not what I'm asking. I'm asking if it's possible, and if so how? Does the standard PC user require a 3rd party app, or can it be done through the command line? Or Terminal if you are on Linux?

  • What is a good solution for an adaptive iptables daemon?

    - by Matt
    I am running a series of web servers and already have a pretty good set of firewall rules set up, however I'm looking for something to monitor the traffic and add rules as needed. I have denyhosts monitoring for bad SSH logins, and that's great - but I'd love something I could apply to the whole machine that would help prevent bute force attacks against my web applications as well, and add rules to block IPs that display evidence of common attacks. I've seen APF, but it looks as though it hasn't been updated in several years. Is it still in use and would it be good for this? Also, what other solutions are out there that would manipulate iptables to behave in some adaptive fashion? I'm running Ubuntu Linux, if that helps.

  • What's the easiest way to create an HTTP proxy which adds basic authentication to requests?

    - by joshdoe
    I am trying to use a service provided by a server which requires basic HTTP authentication, however the application I am using does not support authentication. What I'd like to do is create a proxy that will enable my auth-less application to connect via the proxy (which will add the authentication information) to the server requiring authentication. I'm sure this can be done, however I'm overwhelmed with the number of proxies out there and couldn't find an answer how to do this. Basically it seems all I want to do is have a proxy serve this URL: http://username:password@remoteserver/path as this URL: http://proxyserver/path I can run it on Linux, but a plus if I can run it Windows as well. Open source or at least free is a must. A big plus is if it's fairly straightforward to setup.

  • X won't start, root filesystem mounted read only

    - by TK Kocheran
    I just experienced a very strange and puzzling problem on my machine that I can't seem to get sorted out. I was running Windows on a second partition, and everything was working great. I then went to restart into Linux, and noticed that X wouldn't start. Everything was displayed in super-low resolution, so I tried reinstalling my NVIDIA driver. I started seeing all of these I/O error problems, so I figured that my SSD was bad. After a bit more playing around, I ran fsck on the drive when mounted from a startup disk as well as badsectors and everything looked great. The SMART drive tests all passed and again, everything was looking good, so I rebooted again and still, no joy. I started then getting some weird USB errors, so I followed someone's advice and unplugged my computer's power supply, then started back up again and my graphics looked a lot better in the BIOS and in the boot logo, but X still wouldn't start. I then found out that my main boot drive was being mounted read-only for some reason. What's going wrong? I've done some pretty extensive tests on the SSD from a startup disk such as writing massive files, reading big files, running filesystem checks on the entire disk, and everything is looking great, until I try to boot. Whenever I try installing the drivers with apt-get, I get a ton of ata error messages looking like this: How can I diagnose what's going wrong and fix it so I can get back to work?

  • How to install Windows 7 on Acer Aspire iDea 500?

    - by Martin R-L
    I've got a Windows 7 Ultimate 32-bit from MSDN Subscriber Downloads. The downloaded ISO boots fine from both a USB pen drive and a DVD on other computers. On the Acer it doesn't boot. The Acer iDea 500 can boot, and install, Windows XP Mediacenter from a DVD with slipstreamed SATA drives on it. Also, all kinds of Linux distros works perfectly fine on the iDea 500. I wouldn't mind using Mythbuntu instead of Windows 7 Ultimate, but it doesn't work very well.

  • What free OS should I use on my VPS?

    - by earlz
    Hello, I looked a bit but didn't see any duplicate of this so my question is which free(open source) OS do you use on servers and why do you use that OS? Background I have a VPS at Linode. There is a broad range of options for which OS I can put on it including both 32 and 64bit OSs. I just use it to run my small blog and for hosting random files. It's very low traffic. I have been using 64bit Arch Linux on my VPS and though I love the OS for general usage, for a server the constant breakage is troublesome. So I'm considering trying something new and am looking for suggestions.

  • USB flash module giving errors

    Hi, I have a SATA USB flash module which was earlier running a 2.4 linux kernel (2.4.36.6) and on which now I am trying to install ubuntu server 10.04.1 LTS.

  • Looking for new hosting company

    - by Charles Chadwick
    I am currently looking for a new hosting company for my business. We are a design and development company and have been recommending WestHost to our clients for the last several years. However due to some changes they have implemented in the last year, we have decided to start referring people elsewhere. Most of our clients need affordable Linux hosting with the basics. SSH is also a definite must and 24/7 support (preferably phone, as well as email/ticket system) that won't cost extra. An easy to use and understand control panel would be nice as well. I have heard good things about HostGator, and am wondering if anyone has experience with them. The prices seem right and they have everything we need. We are also thinking of purchasing a dedicated server with them for a specific project that's going to require one. I don't know if I am asking this in the right place, if this is not welcome here please let me know.

  • Getting file system free space

    - by Fred Riley
    This isn't a problem as such, more a request for information based on ignorance of the Linux filesystem. The very short question is: How do I find out how much free and used space there is on the volume from which Ubuntu is running? More detail: I'm running Ubuntu 12.04 from a 64Gb USB3 stick, created from booting up a year-old Ubuntu 12.04 DVD and running Startup Disk Creator. The reason for this is that the Master Boot Record on my hard disk, holding Windoze 7, has gone belly-up, and whilst awaiting a recovery disk I'm running Ubunto off USB or DVD as a 'trial'. (And will continue to run Ubuntu after restoring Windoze, as I've rediscovered my love of the penguin :o)) After installing Ubuntu on the stick I ran the software update app, which downloaded some 450Mb of updates and took a couple of hours to install to the stick. A couple of times I got a message saying that disk space was short. So I looked in the file manager (or whatever it's called these days) and couldn't see the stick listed, just: SYSTEM hard disk (listed as 479Gb Filesystem) two other partitions that had been created by Windoze "4.3GB Filesystem" which when I try to open gives the error "Could not find /cow", and when I try to unmount it tells me I can't because it's not mounted - D'OH!! Edit: screenshot of file manager Edit: screenshot of low disk space warning What I can't see is the USB stick from which I'm running Ubuntu. Where's it gone, anybody know? This is tangentially related to a previous question of mine about system tools, in that I'm trying to get control and knowledge of the system in the newest incarnation of Ubuntu.

  • ifconfig can't see USB wireless

    - by Alex
    I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

  • Why is process not being displayed by TOP

    - by drN
    I am running a Mathematica script (this question probably doesn't fit in Mathematica.SE however) and I know that it generally takes up a lot of RAM and loads up my cores. However, althought pgrep MathKernel is showing a pid, I find that top doesn't show this in the top processes, although I notice that it is taking up about 2.25GB of the 8GB available to me. pmap -x my_process_id total kB 2243132 1907404 1892108 AND ps aux | grep MathKernel dnaneet 20837 12.6 23.3 2234944 1907404 pts/1 Sl 09:23 8:01 /share/apps/mathematica/8.0.4/SystemFiles/Kernel/Binaries/Linux-x86-64/MathKernel -runfirst $TopDirectory="/share/apps/mathematica/8.0.4" -script ./dcm_10micrometer_2x -- ./dcm_10micrometer_2x ps aux shows that the process is taking about 12% (In asterisks) dnaneet 20601 0.0 0.0 68264 1660 pts/1 Ss 09:15 0:00 -bash **dnaneet 20837 12.2 23.3 2234944 1907404 pts/1 Sl 09:23 8:01 /share/apps/mat** dnaneet 21922 0.0 0.0 65604 948 pts/1 R+ 10:29 0:00 ps -aux Did this process fail and is the MathKernel just lingering?
