  • Booting from USB only

    - by vivek
    I am a newbie on linux and dont understand many things unless given a line by line instructions. I am trying but linux does take some getting used to. I have installed ubuntu from live usb stick. Now I cannot boot my system without the usb being plugged in. There are answers whereby certain commands need to be run. For any command that I run with sudo (prefix) the terminal asks me for a password which I dont know. What do I do? How do I fix it such that the booting happens without usb being plugged in. So far I have just been booting from USB. Please help a recent converted from Windows. Thanks all

  • Ubuntu 12.04 and Realtek Wireless Card Incompatible

    - by Tim
    Quick background: I installed Linux Ubuntu 12.04 on a Dell Inspiron 3520 after uninstalling Windows 8. A friend suggested to do this as opposed to buying a laptop with Linux pre-installed. Everything except the wireless card works. When I load up the laptop, I see a wireless animation as if it's trying to locate the wireless connection (for a while, then it goes blank), but no connections appear under the wireless option (under "Edit Connections" then "Wireless"). What I've tried: - Doing ndiswrapper. Failed. - Installing a few kernels for realtek. Failed.

  • Can't boot ubuntu on Lenovo V570

    - by Aaron
    I recently tried to install Ubuntu on my new Lenovo V570, planning to dual boot 11.10 with Windows 7. I realized after installing that it would boot straight into Windows, so I looked up the issue. I read something about UEFI, and found a page suggesting that I wipe the drive with GParted, installing a msdos partition table, and then install Ubuntu. (I tried linux mint first, because that's what I had on my flash drive at the moment.) I attempted this, and now I'm left with a computer that won't boot anything from the hard drive. If I install Ubuntu or Linux Mint 12 using either MSDOS or GPT, it simply skips the hard drive. My BIOS has no option to disable EFI, and I'll admit I know shamefully little about EFI or different types of partition tables. I'd like to know what I have to do to make my computer boot again.

  • My computer boots up with Ubuntu: How can I tell what's on my hard disk?

    - by Larry Harson
    I've acquired an old laptop (Acer TravelMate 4050 with an Italian keyboard) that boots up with the following options: Ubuntu, with Linux 3.0.0-12-generic Ubuntu, with Linux 3.0.0-12-generic (recovery mode) Memory test (memtest86+) Memory test (memtest86+, serial console 115200) When I choose the first option, the screen just goes blank with a flashing cursor. But I can go into grub command mode by typing 'c'. Now, I want to know what operating system is installed, and the files stored on my computer, so how do I do this? What can I do to maximise the use of this computer in its current state?

  • Line6 UX1 soundcard and Ubuntu

    - by the_drow
    I own a Line6 UX1 soundcard and I would like to make it work for Ubuntu. I have followed the instructions here and it worked. But at some point I upgraded my kernel version (not sure what uname -a prints but it's related) and it stopped working. Here's what uname -a prints: Linux ubuntu 2.6.32-29-generic 58-Ubuntu SMP Fri Feb 11 20:52:10 UTC 2011 x86_64 GNU/Linux I figured out that maybe it's installed per version so I used svn update and hit make again. My guess was right as it copied the relevant files to the new version's folder. I restarted and still nothing. Should I revert to an older version? Or is there a solution here?

  • Ubuntu perfomance issues

    - by Pelda
    I have as deafult Win 7 64b. But i get annoyed by some windows stuff so I decided to install ubuntu and learn Linux, because Win 8 is a nightmare. I have my Ubuntu 12.04 64bit installed in 100gb partition of my 1 Tb disc. My problem is that my Ubuntu feel really slower than Win 7 - even though my Win 7 are after some years of usage and they became much slower. And Ubuntu is just installed OS - I just downloaded wine and skype. It takes some time for new window to appear (its not 10 seconds, but its really slower than my windows). Sometimes my donwload get stuck (in basic ubuntu app store) Its just weird to me. I thought its because of some drivers, but I am really new to linux, so I decided to ask some1 before I screw whole system up. Specs: -6gbs of RAM - 3x2gb -3.0 ghz CPU quadcore -graphic card is HD4870 sapphire Please excuse my poor english and my addiction to windows interface. Pelda

  • Application trying to use the wrong shared library

    - by Josh
    I'm having a problem with a program (quartus) running on my ubuntu machine. I'm getting the following error. quartus: symbol lookup error: /usr/lib/i386-linux-gnu/libXi.so: undefined symbol: XESetWireToEventCookie I have the correct libXi.so.6.0.0 file but no matter where I put it, the OS won't use it unless I apt-get remove libxi-dev, but a lot of software uses this libXi. What I want to do is add some sort of exception to the dynamic linker so that quartus uses the libXi.so that it needs and everything else still uses the one in /usr/lib/i386-linux-gnu. Thanks!

  • System checks for disk drive error every time it boots

    - by Starx
    When my disk space for the ubuntu installation partition was getting low, from a live cd, I used gparted to increase its volume capacity, but deleting another partition and merging it to the ubuntu partition. Since then onwards, I am receiving disk checking for errors at boot screen for my partitions, always. What seem to be causing this and how to fix it? Update Here is my boot.log if it provides few insight fsck from util-linux 2.19.1 fsck from util-linux 2.19.1 /dev/sda1 was not cleanly unmounted, check forced. ubuntu: clean, 501325/1310720 files, 2958455/5242880 blocks /dev/sda1: 241/51272 files (3.3% non-contiguous), 73541/102400 blocks mountall: fsck /boot [358] terminated with status 1 Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox ... /dev/sda1 is a separate grub partition for my dual OS's

Any Way around this or perhaps a different way to uninstall?

  • Ops Center and Oracle Solaris 11

    - by user12609425
    There have been a few questions about Ops Center and S11 recently. People have been trying to discover and update S11 from Enterprise Controllers installed on S10 or Linux, and running into problems, and wondering what the solution is. Well, the solution is that, if you want to be able to discover, monitor, and update S11 OSes, you need to install your Enterprise Controller and at least one Proxy Controller on S11 systems. The Oracle Solaris and Linux install guides both note this in the chapters that cover preparing your environment. Technically, if you have an S11 Proxy Controller you can at least discover, manage, and monitor S11 systems. However, features like the automated installer and the image packaging system (for OS updates) can only be used through Ops Center if your Enterprise Controller is installed on S11 as well.

  • How do I install latest NVIDIA drivers?

    - by Shahe Tajiryan
    This is what I am trying to do. I downloaded the latest driver for my VGA from http://www.nvidia.com. The installation needs the X11 to be shut down, so I log out of my account, then press CTRL+ALT+F1, then log in with my username and passowrd, then run the command sh NVIDIA-Linux-x86_64-285.05.09.run in every possible way, I have even tried CHMODing the package with 777 permissions, but still I'm getting the sh: can't open NVIDIA-Linux-x86_64-285.05.09.run error. Any help would be greatly appreciated.

  • "You are missing the following 32-bit libraries, and Steam may not run: libc.so.6" The common fixes don't work,

    - by M_Steam_User
    So I know this is a problem that has been asked around a lot, but I've tried a bunch of solutions with no success. I'm running Ubuntu 12.04 (64 bit), and I just installed it yesterday. This is my first time working with linux. The error is: You are missing the following 32-bit libraries, and Steam may not run: libc.so.6 Things I've tried. First, I had downloaded from the steam website. I uninstalled it, and tried again from the ubuntu software centre. sudo apt-get update sudo apt-get install ia32-libs sudo apt-get upgrade This installed a bunch of the 32 bit libraries, but did not fix the issue. This seems like the major fix for most people. The direct approach of sudo apt-get install libc.so.6 returns this: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libc.so.6 E: Couldn't find any package by regex 'libc.so.6' I guess libc.so.6 isn't a package, just a single file or something? I also tried gksudo gedit /etc/ld.so.conf.d/steam.conf Added these two lines, those the second one was all ready in the file, but copied over: /usr/lib32 /usr/lib/i386-linux-gnu/mesa Then executed: sudo ldconfig But nothing seemed to happen, steam still doesn't work. So, I feel like it is more likely that I have the library and steam isn't looking in the right place. One thing I've seen is people usually reference /usr/local/lib/ for your library locations. However, I can't find where to cd into /usr/, it isn't in my home folder. If /usr/ is the home folder, there is only a /.local folder which only has /share, no lib anywhere. Sorry for my linux ignorance. I appreciate any help, I honestly have no idea how to confirm I have the library and point steam to it, or if that is even the right thing to do. Edit: Tried this, not entirely sure what it means ~$ ls -l /lib32/libc* -rwxr-xr-x 1 root root 1721832 Sep 30 11:06 /lib32/libc-2.15.so -rw-r--r-- 1 root root 185928 Sep 30 11:06 /lib32/libcidn-2.15.so lrwxrwxrwx 1 root root 15 Sep 30 11:06 /lib32/libcidn.so.1 -> libcidn-2.15.so -rw-r--r-- 1 root root 34316 Sep 30 11:06 /lib32/libcrypt-2.15.so lrwxrwxrwx 1 root root 16 Sep 30 11:06 /lib32/libcrypt.so.1 -> libcrypt-2.15.so lrwxrwxrwx 1 root root 12 Sep 30 11:06 /lib32/libc.so.6 -> libc-2.15.so

  • Should I switch my graphics mode in the BIOS to avoid using Bumblebee?

    - by Fawkes5
    I have just purchased a Acer 3830TG, the timeline X series. To my surprise I found out that there is no first-party support for nvidia optimus for linux. Bumblebee works great, but the battery life from the graphics card always running is not so great. I don't use linux for games so i don't really need the graphics card on, I have Windows for that. In my bios, I have the ability to change my graphics mode from switchable to integrated. If I do this, reinstall ubuntu, what will happen? Will my nvidia card just turn off? Will everything work properly, as if i'm not running an optimus laptop? Is this recommended as opposed to dealing with bumblebee? What is the best thing I could do?

  • Why Android for new (micro) consoles?

    - by Klaim
    There are a lot of new (micro) consoles with Android inside coming soon or already there (OUYA for example). My question is: why use Android and not another OS as base for these consoles? I assume that there are pragmatic answers to this but I can't see any clear killer feature. For example, one can assume that any stable Linux distribution would work (like Valve seem to think). Android is primarily targetted at mobile platforms which mean it is built around the idea of being interrupted which goes against a lot of what console devs needs in new hardware - but is not killing Android as a platform for gamedev either as it's just a constraint. Why not another OS? What's the Android killer features that make micro-console builder using it instead of Linux or anything else?

  • Advice on triple/quadruple-booting?

    - by professorfish
    I am currently running Windows 7 Home Premium x64 on my laptop. I would like to install more than one Linux distro, IN ADDITION TO Windows 7. How do I go about this, what do I need to be careful and aware of, is it possible? The specific distros I might eventually install: Definitely: Ubuntu (is it a good idea to install the Linux-Secure-Remix version?) Almost definitely: OpenSUSE Probably: Zorin Possibly: Arch Possibly: Fedora Possibly: FreeBSD Computer details: Successfully used WUBI for Ubuntu in the past Recently reinstalled Windows using the RECOVERY partition Windows 7 Home Premium x64 model: ASUS K53U series AMD Brazos Dual Core E450 1.65 GHz 750GB hard drive, currently partitioned into C: (300GB total, 246 GB free), D: (373GB - total, 167 GB free), and RECOVERY (the rest of the space, I think) 4GB RAM Can I be sure that GRUB will work, if WUBI has worked? In short, how do I go about triple- or quadruple-booting Windows 7, Ubuntu and other distros? What do I need to be aware of? How do I set up the partition structure? Thank you in advance

  • Running Mixed Physical and Virtual Exalogic Elastic Cloud Software Versions in an Exalogic Rack is now Supported

    - by csoto
    Although it was not supported on older versions, now as of EECS 2.0.6, an Exalogic rack can be configured in a mixed-mode: half virtual and half physical Linux: Flexibility to have physical and virtual environments on same rack. For example, production on physical and test/dev on virtual. Exalogic Control manages the virtual compute nodes on the rack. Physical compute nodes are managed manually (including PKeys). Option to change full physical to hybrid and hybrid to full virtual rack. User has an option to choose either the top or bottom nodes for physical or virtual deployment. For further information about how the compute nodes can be split up on the rack (into bottom or top half) to run either Oracle Virtual Server (OVS "hypervisor") or Oracle Linux, please take a look at MOS Note 1536945.1. Note: Solaris is not yet supported in the mixed configuration.

  • Ubuntu 11.04 seem's like a laggy OS

    - by user772401
    I'm new to Linux/Ubuntu in general. I just dual booted the Ubuntu 11.04 w/Windows 7 on my Lenovo laptop - Intel i7 Quad Core 2Ghz, 4Gb ram, etc. etc... and for some reason Ubuntu is very laggy and slow. When I'm switching between programs (Chromium, folders, software center, etc..) it doesn't run as smooth as windows 7 (I have no more than 3 programs/windows up at a time...). I don't think it's my system requirements bkz Linux OSs are known to use low system resources. Could be a bad install or do people find it slow and laggy in general or is it my PC mfg type?? I installed it using Wubi - should I do a reinstall? I've already done all the recommended updates..
