  • Installing raid 5 on a pre-installed ubuntu server. 12.04

    - by Chris
    I have a ubuntu server with samba already set up and installed with a 1tb hdd. I am wanting to now install 3 more 1tb drives and create a raid array using raid 5. I have found a lot of documentation about installing raid when installing and setting up ubuntu server for the first time. However, I am struggling to find anything on installing a raid 5 array on a system already installed an configured. Can this be done, or does a clean install need to be done again?

  • ISO booting with grub2 in Ubuntu on an Apple

    - by Robert Vila
    I have Ubuntu with grub2 installed in an Apple Macbook pro with dual boot (using rEFIt), and I would like to use grub2 to boot the LiveCD ISO image of a system based in Debian too (CrunchBang). The ISO image is saved in the same hard disk, same partition as Ubuntu. I can easily boot many other LiveCD ISO images, but I cannot boot this one, and I cannot boot the MacOS system, from the grub menu, either. The installation of Ubuntu left a couple of menu entries to boot MacOS, but they never worked. SO I don't know if it is possible to boot them, and how. I have tried many options, but the menuentry I am trying now to boot crunchBang is this one: menuentry "crunchbang-10-20120207-i386.iso" { set isofile="/home/user/Desktop/ISO/crunchbang-10-20120207-i386.iso" loopback loop (hd0,3)$isofile linux (loop)/live/vmlinuz1 iso-scan/filename=$isofile toram=filesystem.squashfs findiso=$isofile boot=live config -- initrd (loop)/live/initrd1.img } And I copied it from here: http://linux4netbook.blogspot.com.es/2012/08/due-crunchbang-e-un-pennino.html

  • Can't log to mySQL

    Even after I reset root password with following command I can not log to mySQL: (other command listed to provide additional info) # sudo dpkg-reconfigure mysql-server-5.1 # mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) # telnet 127.0.0.1 3306 Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused # ps -Aw |grep mysql 26522 ? 00:00:00 mysqld # /etc/init.d/mysql start Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service mysql start Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility, e.g. start mysql update: # sudo mysqladmin -u root password 123 mysqladmin: connect to server at 'localhost' failed it seems mysql is not ruining properly

  • "Never hide" Unity launcher via CCSM & gconf doesn't work

    - by Jim Holman
    All: I am running Unity 3D and I want to set my launcher to never hide. I first ran ccsm, and set "Hide Launcher" to "Never". I rebooted then logged back in and it was still auto-hiding. I then ran gconf-editor, I navigated to /apps/compiz-1/plugins/unityshell/screen0/options and then set launcher_hide_mode to 0. I again rebooted and logged back in. The launcher is still auto-hiding. Checking gconf-editor, launcher_hide_mode is set to 0, but this setting isn't active however. What can I do to get the launcher to Never hide? Thanks, Jim

  • How to stream H264 Video from camera over FTP?

    - by Jay
    I bought a h264 security camera system last year and set it up to ftp video to my computer. I was able to get the video to play (even though it played a little fast) on Ubuntu 11.04 using mplayer. A few months ago, I did a fresh install of 12.04 and I cannot seem to get the video to play with mplayer, smplayer or VLC. I have the restricted formats video packages installed and when playing with any of the players, all I get is a gray video. When calling mplayer from the command line to play the video with no options, I get a lot of these errors: [h264 @ 0x7f278c61f280]concealing 1320 DC, 1320 AC, 1320 MV errors No pts value from demuxer to use for frame! pts after filters MISSING I'm not a video expert and have been coming up with a lot of dead ends when Googling for this.

  • Hancon / Hanwang Graphics Tablet not recognised

    - by Martin Kyle
    I'm totally lost. I've just built a new system and installed Ubuntu 12.04. It's my first time with Linux and getting into the terminal / command line for the first time since IBMDOS 5 and Windows 3.1 has been a steep learning curve. However, the interface works beautifully apart from it doesn't recognize my Hanvon Artmaster AM1209. I have sent diagnostics to Digimend and Favux was kind enough to advise that the tablet should be using the Wacom X driver as the Hanvon is actually a Hanwang and these should be supported. lsusb reports: ID 0b57:8501 Beijing HanwangTechnology Co., Ltd xinput list reports: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? PS/2+USB Mouse id=8 [slave pointer (2)] ? Virtual core keyboard id=3 [master keyboard (2)] ? Virtual core XTEST keyboard id=5 [slave keyboard (3)] ? Power Button id=6 [slave keyboard (3)] ? Power Button id=7 [slave keyboard (3)] ? Eee PC WMI hotkeys id=9 [slave keyboard (3)] ? AT Translated Set 2 keyboard id=10 [slave keyboard (3)] Favux suggested inspecting /var/log/Xorg.0.log for the tablet but I cannot see any mention of it, and that is as far as I have got. I've tried researching the problem but I am struggling with all the new terminology and the fact that I want the PC to be a means to an end and not the end in itself where I spend the rest of my days tweaking and testing rather than just using it. Hope there is some help out there.

  • Downloads killing internet on my home network

    - by Travis
    I am currently having a problem with my wireless. Whenever I try to download anything it kills the internet for every other application(tabs within the same browser, browsers on other computers on the same network) except the process doing the download. This occurs with everything from downloading updates to iso's. I am not using a torrent. It happens when downloading upgrades, browser downloads, or anything else. This problem does not occur when I use Windows 7 on the same computer and it stops killing the internet for other computers if I turn the download/Ubuntu off. I am using an ASUS G74SX laptop running Ubuntu 12.10 with Gnome 3.6. My wireless card is an Intel Corporation Centrino Wireless-N + WiMAX 6150 (rev 67) Thanks!

  • Remove partition for failed installation

    - by kapitanluffy
    i tried installing ubuntu alongside windows 7 Installing Ubuntu alongside Windows and i failed so i decided to go with wubi again. after installing it, i noticed a separate hard disk. i investigated and found out that this hard disk is actually for the failed installation. i don't know where to find it inside the windows system. can anyone please teach me how to remove the 'failed' hard disk. here's a screenshot the left side is the current filesystem. the right side on the other hand is the 'failed' harddisk. i verified that it is the failed one because the wubi installation will provide a 'host' folder for the current partition it is currently installed. i tried looking for the 'failed' one using the windows' commandline but i don't know where to look for the 'failed' disk. (i used the cmd coz i don't want root.disk to mysteriously disappear again.) see http://ubuntu-with-wubi.blogspot.com/2011/01/mystery-of-disappearing-rootdisk.html

  • How to share two keyboard on the same laptop, french iso layout and usa ansi layout keyboard with usb?

    - by reyman64
    I recently buy a "noppoo choc mini" with this specific ANSI US-INTERNATIONAL pc84 layout. This specific keyboard have only 84 key , a 60% (compact tenkeyless) reduced layout My problem is simple, there is no keyboard layout into Ubuntu 12.04 which correspond to this usa normal ansi layout ... so it's the same problem with reduced version and only 84 key .. I search a template of normal ANSI US-INTERNATIONAL for xmodmap/xkb, and after i can try to manually map the other key. I search on google, and i don't find any other user which have same problem, so it's seem i have not the good keywoard to search this information.. Edit 1 : Here you can see there is probably a bug in ubuntu, because the layout for USA with dead key is not correct ! I have this : http://minus.com/lEdKMrsNAwkVA And other users have this for the same layout : http://i.stack.imgur.com/p52XG.png EDIT 2 It seems after a "sudo dpkg-reconfigure keyboard-configuration" : french standard keyboard pc105 + precision M65 keyboard from dell laptop Now i can see the good us layout in parameters, but i cannot have the iso layout for french usage... EDIT 3 Ok, after reboot i understand the probleme, i explain. I have one laptop with integrated french keyboard, and i want to use my usb keyboard which use a usa ANSI layout. It seem it's impossible in ubuntu and "dpkg-reconfigure keyboard-configuration" to share two different physical layout (ANSI and EU ISO) on the same computer ... EDIT4 Ok, it seems i can switch the physical layout (ISO <- ANSI) with this command in terminal : setxkbmap -layout us setxkbmap -layout us -variant alt-intl an setxkbmap -layout fr It's very complicated qnd it seem ubuntu 12.04 have big problem with keyboard manager ... because all works great with these two commands, without ANY change into the system parameters keyboard !!! Second bug ? The image of the layout for fr is buggy, the layout is not ISO, but i can press on the letter "< " at the left of right shift without any problem ! You can see the image here (french alternative with ANSI layout ? it's crazy ?) : http: //minus.com/lXsDJwoeyWAfF Can you help me on this point ? I'm lost with xkb, and manual mapping is very complicated ... Thanks a lot, SR

  • Using portable Mode for true crypt for crypting Portable HDD , USB etc

    - by Gaurav_Java
    I was wondering how to encrypt my external HDD so that my data would be safe AND accessible from any OS platform (Windows and Linux). So I went through many posts and forums and found out the best thing was to use true crypt. I went along with this post and encrypt my USB drive. When inserted that, Windows didn't recognize it. Then I followed another post that said to install truecrypt. The thing is : How can i use traveler disk setup in Ubuntu (Option not found)? Install truecrypt in USB so that i can *mount my USB or HDD on any other OS? If there is no solution for the upper two, then is there any other software which I can use to encrypt an USB device so that it can be accessed from any OS?

  • Bash script throws, "syntax error near unexpected token `}'" when ran

    - by Tab00
    I am trying to write a script to monitor some battery statuses on a laptop running as a server.

(The examination of SM points out a rather poignant factor in the faster battery depletion and shortened run time - the ambient quiescent CPU rate in 12.04 is now well over 20% when previously, in 10.04, it was well under 10%, between 5% and 7%! - the huge inordinate cpu overhead originates from Xorg and compiz - after booting the system, only SM is run and All Processes are selected, sorting on %CPU - switching between Resources and Processes profiles the execution overhead problem - running another ap like gedit "Text Editor" briefly gives it CPU priority - going back to S&M several aps. are at the top of the list in order: gnome-system-monitor as expected, then: Xorg, compiz, unity-panel-service, hud-service, with dbus-daemon and kworker/x:y's mixed in with some expected daemons and background tasks like nm-applet - not only do Xorg and compiz require excessive CPU time but their entourage has to come along too! further exacerbating the problem - our compute bound tasks no longer work effectively in the field - reduced battery life, reduced CPU time for custom ap.s etc. - and all this precipitated from an examination of what is going on with the battery ap. indicator - this was and is not a flippant, rhetorical or idle musing but has consequences for the credible deployment of 12.04 to reduce the negative impact of its overhead in a production environment) (I have a problem with the battery indicator - it sometimes has % and other times hh:mm - it is necessary to know the ap. & v. to get more info on controlling same. ditto: There are issues with other indicator aps.: NM vs. iwlist/iwconfig conflict, BT ap. vs RF switch, Battery ap. w/ no suspend/sleep for poor battery runtime, ... the list goes on) Details from: How can I find Application Indicator ID's? suggests looking at: file:///usr/share/indicator-application/ordering-override.keyfile [Ordering Index Overrides] nm-applet=1 gnome-power-manager=2 ibus=3 gst-keyboard-xkb=4 gsd-keyboard-xkb=5 which solves the battery ap. identification, and presumably nm is NetworkManager for the rf icon, but the envelope, blue tooth and speaker indicator aps. are still a mystery. (Also, the ordering is not correlated.) Mind you, it was simple in the past to simply right click to get the About option to find the ap. & v. info. browsing around and about: file:///usr/share/indicator-application/ordering-override.keyfile examined: file:///usr/share/indicators file:///usr/share/indicators/messages/applications/ ... perhaps?/presumably? the information sought may be buried in file:///usr/share/indicators A reference in the comments was given to: What is the difference between indicators and a system tray? quoting from that source ... Unfortunately desktop indicators are not well documented yet: I couldn't find any specification doc ... Well ... the actual document https://wiki.ubuntu.com/DesktopExperienceTeam/ApplicationIndicators#Summary does not help much but it's existential information provides considerable insight ...

  • Using GPU's RAM as RAMDISK

    - by user3476043
    I want to use my GPU's ram as a ramdisk, following these instructions : http://en.gentoo-wiki.com/wiki/Using_Graphics_Card_Memory_as_Swap But when I input the " modprobe phram phram=VRAM,0xd8400000,124Mi " command, I get the following error : modprobe: ERROR: could not insert 'phram': Input/output error I use Ubuntu Studio 14.04. Also, is there anyway I could use more than the 128M of prefetchable memory, my GPU has 1GB of ram, I would prefer to use "most" of it.

  • How to install new Intel Ethernet driver

    - by Alex Farber
    Ubuntu 12.04 x64 doesn't recognize newest Intel Ethernet adapter on my desktop (Intel Ethernet Connection i217-V). I downloaded required driver from Intel and compiled it using make. Now I have: alex@alex64-six:~$ find / -name 'e1000e.ko' 2>/dev/null /home/alex/Documents/IntelEthernetDriver/e1000e-3.0.4/src/e1000e.ko /lib/modules/3.2.0-64-generic/kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko The first line is new driver compiled from Intel sources. The second line is probably existing driver from Ubuntu distribution, which doesn't recognize new Ethernet adapter. How can I apply the new driver instead of existing one? Any other solution is welcome. For now, I cannot upgrade to latest Ubuntu release, because I use some third-party products.

  • Be able to create edit and move files to and from /var/www

    - by Ryan Murphy
    I have installed lamp on Ubuntu 12.04. I try to access /var/www but it doesn't allow me to do anything as it says I don't have permissions. I have tried: 1. gksudo nautilus - which works but its very inconvenient way of doing things. 2. sudo adduser ryan www-data sudo chown -R www-data:www-data /var/www sudo chmod g+rw /var/www The above didn't work. I have googled and searched this site for a solution, but all the existing possible solutions have not worked.

  • Raleigh theme on LightDM, Ubuntu desktop, Nautilus window, menus & menu-bars

    - by Tassos Seligkas
    After performing an upgrade from Natty to Oneiric, I had a problem similar to the one reported in here at every system boot: Desktop forgets theme? Everything, from the LigthDM greeter to the ubuntu desktop used the ugly raleigh theme, apart from firefox, thunderbird few other applications after logging in. Unfortunately none of the solutions suggested in the topic above worked for me. The only way I could get acceptable appearance would be to switch to gnome at login and using the Adwaita theme. The lightdm greeter still uses the raleigh theme though. Unfortunately, I tried some "brute-force" methods by reinstalling (sudo apt-get install --reinstall) ubuntu-desktop, unity, unity-common, unity-greeter, gnome-session, gtk2-engines. I also tried moving .config, .gconf, .gconfd, .gnome, .gnome2 to a backup dir to reset account desktop preferences. None of the above solved the issue. On the contrary, logging-in to Ubuntu setup does not show unity and window decorations anymore. My fallback remains the Gnome logon and the Adwaita theme. This is my workstation machine I am hosting Ubuntu on, so, though possible, it is time consuming to perform a backup and format-reinstall ubuntu 11.10. Could you please let me know if I can get an alternative way of repairing my ubuntu desktop? (I believe it all started when, during the 11.04-to-11.10 upgrade, the installation of downloaded packages for oneiric broke when nautilus-dropbox failed to access the dropbox servers - I am behind a proxy but with proper proxy settings had no problems using apt-get & synaptic. However I removed dropbox and resumed partial installation on second boot.)

  • How to fix VMware Workstation 9 installation on ubuntu 12.10?

    - by Alessandro Belloni
    I have opened this thread because I upgraded to ubuntu 12.10 beta (kernel 3.5) and I have a problem with VMware Workstation 9: Unable to change virtual machine power state: Cannot find a valid peer process to connect to Does anyone have the same problem? This is a clean install of Ubuntu 12.10 (daily build). I installed VMware 9 and patched but it's not working. I can't patch correctly and get the things to build correctly. My laptop is a Lenovo T420 with Nvidia Optimus Technology. This message is shown when I try to apply the patch: Stopping VMware services: VMware Authentication Daemon done At least one instance of VMware VMX is still running. Please stop all running instances of VMware VMX first. VMware Authentication Daemon done Unable to stop services How can I stop the VMware services to apply the patch? This message is shown when I try to patch again: ./patch-modules_3.5.0.sh /usr/lib/vmware/modules/source/.patched found. You have already patched your sources. Exiting But VMware is not working, and I can’t uninstall.

  • Is It Possible To Recover A Partial LVM Logical Volume?

    - by Terry Wang
    Background It is an Ubuntu 12.04 VirtualBox VM with 5 virtual HDDs (VDI), NOTE this is just a test VM, so not well planned ahead: ubuntu.vdi for / (/dev/mapper/ubuntu-root AKA /dev/ubuntu/root) and /home (/dev/mapper/ubuntu-home) weblogic.vdi - /dev/sdb (mounted on /bea for weblogic and other stuff) btrfs1.vdi - /dev/sdc (part of btrfs -m raid1 -d raid1 configuration) btrfs2.vdi - /dev/sdd (part of btrfs -m raid1 -d raid1 configuration) more.vdi - /dev/sde (added this virtual HDD because / ran out of inodes and it wasn't easy to figure out what to delete so as to free up inodes, so I just added the new virtual HDD, created PV, added it to existing volume group ubuntu, grew the root logical volume to work around the inode issue -_-) What happened? Last Friday, before finishing up I wanted to free up some disk space on that box, for some reason I thought the more.vdi was useless and tried to detach it from the VM, I then clicked delete (should have clicked keep files damn!) by mistake when detaching. Unfortunately I didn't have backup for it. All too late. What I have tried Tried to undelete (use testdisk and photorec) the vdi files but it takes too long and recovered heaps of .vdi files that I didn't want (huge, filled the disk, damn!). I finally gave up. Fortunately most of data is on separate ext4 partition and btrfs volumes. Out of curiosity, I still tried to mount the logical volumes and see if it is possible to at least recover the /var and /etc I tried to use system rescue cd to boot and activate the volume groups, I got: Couldn't find device with uuid xxxx. Refusing activation of the partial LV root. Use --partial to override. 1 logical volume(s) in volume group "ubuntu" now active. I was able to mount home LV but not root LV. I am wondering if it is possible to access the root LV any more. Under the bonnet, data (on LV root - /) was striped to more.vdi (PV), I know it's almost impossible to to recover. But I am still curious about how system administrator/DevOps guys deal with this sort of situation;-) Thanks in advance.

  • resolv.conf doesn't get set on reboot when networking is configured for static ip

    - by kenneth koontz
    I'm experiencing, what appears to be a hostname resolution issue in ubuntu 12.04 server edition when configuring my computer to use a static ip. In /etc/network/interfaces: # The primary network interface auto eth0 iface eth0 inet static address 192.168.1.28 netmask 255.255.255.0 gateway 192.168.1.1 Running $ sudo apt-get upgrade, results in a 'Failed to fetch...': . . . W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-backports/universe/i18n/Translation-en_US Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname) W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-backports/universe/i18n/Translation-en Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname) E: Some index files failed to download. They have been ignored, or old ones used instead. When I change my /etc/network/interfaces to: auto eth0 iface eth0 inet dhcp Everything works fine. Looking into /etc/resolv.conf provides some more hints...In cases where I was getting the resolving issue, resolve.conf was empty. No nameservers were specified. When I changed to dhcp from static and restarted networking. /etc/resolv.conf gets written to: 'nameserver 192.168.1.1'. Switching back from dhcp to static and restarting doesn't remove the nameserve entry. When I restart the system with static set, resolv.conf is empty. When I restart the system with dhcp set, resolv.conf has nameserver 192.168.1.1. So it appears that the issue is that resolve.conf is not getting written to correctly? Which package/code is responsible for writing to resolv.conf? Is there a particular package that I can take a look at open issues? UPDATE: istream posted a good article discussing changes to resolve.conf in 12.04. http://www.stgraber.org/2012/02/24/dns-in-ubuntu-12-04/

  • Ubuntu 13.10 AdobeAIR application: Failed to load module "unity-gtk-module"

    - by nobuzz
    I have installed AdobeAIR on 13.10, but am getting the following error messages when using: Gtk-Message: Failed to load module "overlay-scrollbar" Gtk-Message: Failed to load module "unity-gtk-module" Has someone faced this issue. I looked at comment giving a possible resolution here , but that didn't help, as I already have those packages installed. Basically to install AdobeAIR, being a 32-bit, I had to install various i386 packages: libgtk2.0-0:i386 libnss3-1d:i386 libnspr4-0d:i386 lib32nss-mdns libxml2:i386 libxslt1.1:i386 When I run the program as root, it opens up properly without errors. But that is not an option. Could it be a problem that necessary modules are not getting loaded on non-root user's environment.

  • Does Ubuntu generally post timely security updates?

    - by Jo Liss
    Concrete issue: The Oneiric nginx package is at version 1.0.5-1, released in July 2011 according to the changelog. The recent memory-disclosure vulnerability (advisory page, CVE-2012-1180, DSA-2434-1) isn't fixed in 1.0.5-1. If I'm not misreading the Ubuntu CVE page, all Ubuntu versions seem to ship a vulnerable nginx. Is this true? If so: I though there was a security team at Canonical that's actively working on issues like this, so I expected to get a security update within a short timeframe (hours or days) through apt-get update. Is this expectation -- that keeping my packages up-to-date is enough to stop my server from having known vulnerabilities -- generally wrong? If so: What should I do to keep it secure? Reading the Ubuntu security notices wouldn't have helped in this case, as the nginx vulnerability was never posted there.

  • Error:couldn't read file-Kernel panic

    - by Thanos
    I have just installed ubuntu 12.04.1. To be honest I had to run installation several times until it was finished fine. When I finally managed to install it properly, I power on the laptop and the grub shoed up! I selected ubuntu generic. It takes some time to load and when it does I get an error message stating that error: couldn't read file Press any key to continue If I press any button nothing happens. If a leave it there, in a short while there is a black screen loading which gives some weird messages [0.946710] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0) [0.946755] Pid: 1, comm: swapper/0 Not tainted 3.2.0-29-generic #46-Ubuntu [0.946792] Call Trace: [0.946831] [<ffffffff81640ec8>] panic+0x91/0x1a4 [0.946869] [<ffffffff81cfc01e>] mount_block_root+0xdc/0x18e [0.946909] [<ffffffff81002930>] ? populate_rootfs_wait+0x300/0x9d0 [0.946947] [<ffffffff81cfc257>] mount_root+0x54/0x59 [0.946982] [<ffffffff81cfcec9>] prepare_namespace+0x16d/0x1a6 [0.947019] [<ffffffff81cfbd63>] kernel_init+0x153/0x158 [0.947094] [<ffffffff81cfbc10>] ? start_kernel+0x3bd/0x3bd [0.947129] [<ffffffff81664030>] ? gs_change+0x13/0x13 The thing is that the laptop isn't mine. A friend tried to dual boot ubuntu alongside windows 7 but he didn't succeed. Ubuntu option was in grub, but when you tried to boot it rebooted from the start. So from a Live CD I erased ubuntu, started windows to check if something went wrong, and fortunately everything was OK. Windows started normally! So I tried to install ubuntu. Before installation was completed the installer crashed! I was afraid that he would lost windows, something that was true... At that point I tried to install windows but whichever distro(XP, 7{home, proffessional, ultimate},8) I tried it could never reach the end. So I tried to reinstall ubuntu but I was facing those weird messages. What can I do to move on? ______________________________________________________________________ EDIT1: I tried to check and fix(if possible) with GParted it took a lot of hours,although gparted displays only 01:14, I restarted the system and now I get not exactly the same messages. Numbers in braces [ ] are different [0.818189] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0) [0.818235] Pid: 1, comm: swapper/0 Not tainted 3.2.0-29-generic #46-Ubuntu [0.818272] Call Trace: [0.818312] [<ffffffff81640ec8>] panic+0x91/0x1a4 [0.818351] [<ffffffff81cfc01e>] mount_block_root+0xdc/0x18e [0.818391] [<ffffffff81002930>] ? populate_rootfs_wait+0x300/0x9d0 [0.818428] [<ffffffff81cfc257>] mount_root+0x54/0x59 [0.818464] [<ffffffff81cfcec9>] prepare_namespace+0x16d/0x1a6 [0.818501] [<ffffffff81cfbd63>] kernel_init+0x153/0x158 [0.818574] [<ffffffff81cfbc10>] ? start_kernel+0x3bd/0x3bd [0.818610] [<ffffffff81664030>] ? gs_change+0x13/0x13 What on earth is going on? ______________________________________________________________________ EDIT2: I forgot to mention that my friend gave a punch to his laptop during a game. After that his cooler became to make a weird noise so I checked and it is a bit tortuous but it is working. What I beleive must be wrong is that his HDD makes a weird noise while trying to load ubuntu, which means he might need a new HDD. Could that be true?
