• Error after installing Lubuntu 14.04 through liveUSB

  - by Veritas

  A friend asked me to install ubuntu on his toshiba NB 200 netbook to replace windows xp. I formatted the flash drive, ran an nb5sum check on the iso and after running netbootin , I checked the drive for errors. No problems so far. During the installation, while everything seemed normal, the installation regularly paused until I pressed a button or moved the mouse. After restarting, it doesn't boot and it starts a shell showing : "General error mounting filesystems A maintenance shell will now be started CONTROL-D will terminate this shell and reboot the system " Any ideas? Any help is appreciated!

• Wireless not working with a Compaq Presario CQ57

  - by X I V

  This is the first time I installed ubuntu. I first installed 11.04 then upgraded. When I installed 11.04, the wireless card was detected and the driver was installed instantly. Everything worked so far. The thing is that as soon as I upgraded to 12.04, it stopped working. I've tried several solutions from all of the internet but nothing seems to work. What can I do? I really don't know much about ubuntu.

• Booting but not rebooting from external USB hard drive, what could be the problem?

  - by user8276

  I have a Dell Inspiron 6400 laptop with a dead internal hard drive controller. It boots perfectly from CD or USB. I therefore removed the internal hard drive and installed Ubuntu 10.10 Maverick onto an external USB hard drive. It boots and runs perfectly when doing a "cold start" of the PC. However, when I choose restart/reboot in the Ubuntu menu (e.g. after an update), I get this error message from the BIOS: "No bootable devices, strike f1 to retry boot, f2 for setup utility, press f5 to run onboard diagnostics". I can make the system boot again by pressing f2 or f5 and exiting the utility without having done anything. Or, I can simply power off the system and do a new "cold start". Does anyone know the likely reason for this problem and how to fix it. It is not a big issue but an annoyance that I would like to fix if possible.

• Trying to boot from USB on Asus q200e-bhi3t45 just brings me to grub menu

  - by Krash Kharma

  It's been a struggle every time I've tried to change my OS on this machine. I honestly don't even know how it works whenever it does. I've somehow managed to get Windows 7, Windows 8, Mint 14, Ubuntu 12.04, and 12.10 to work at random times but it's always after struggling with it and googling for random chance fixes and suddenly something clicks and it loads from usb, but 99% of the time, every time I try to boot from USB to install a distro (in this case, I'm trying to get ubuntu-12.04.2-desktop-amd64.iso to work) my pc just comes up with a grub menu ("Minimal bash-like blahblahblah - grub ") I don't know why it works when it works. Right now I've tried everything from with/without Fast Boot in BIOS, with/without CSM, with/without secure boot, to changing BOOTx64.EFI to bootx64.efi to downloading a new bootx64.efi to copying it to every folder on the usb.... It makes no sense to me. Sorry if this has been asked before but I can't find anything

• Disable automatic starting of sshd?

  - by b.long

  Simple question here; what's the correct way to stop the sshd service from starting when the OS boots ? I'm not sure if this answer is correct, so I'm hoping some guru(s) can help me out! What I'd like is a configuration that (after boot) allows me to start the service using sudo service ssh start when necessary. Version info: me@home:~$ ssh -V OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 me@home:~$ lsb_release -a No LSB modules are available.

• When booting from grub2 menu, why does only the Primary OS that installed the boot loader get the nice splash?

  - by Matt

  It isn't a real problem, but if there is a way to fix it, I would like to. I have several Ubuntu installations on one computer, but on boot and shutdown, only the primary installation that grub was installed to the MBR from has a nice resolution and boot splash. All the other installations boot splash's are a blinking cursor on a black screen, and the resolution is ugly, on boot as well as shutdown. Why is this? and Can I make it so that my Ubuntu 12.04 have a nice boot again, like my 12.10 now does (because its grub wrote over MBR)?

• shortcuts/links to windows partition disappear on reboot

  - by al kirsch

  Ubuntu 11.10 recognizes my Windows 7 partition OK. Since that is where my work has historically been, I created links to various files and folders there. Everythings fine until I reboot. Then the icon reverts to the generic and I am informed the link is no longer valid. I created the links by right-clicking the folder or file and selecting "Make Link" in the Windows folder, then dragging it to the Ubuntu desktop. How can I fix this? BTW, it worked OK with Kubuntu; I got seduced by the sexy Unity desktop.....

• Distorted graphics, problems with starting up

  - by GreenEggsAndHam64

  Using the newest version of Ubuntu, freshly installed. NVIDIA GeForce GTX 560 Ti. It's mostly the font that doesn't render well, I think. Small logos do it too, sometimes. Screenshot to clarify (see bookmarks, search bar, etc.). EDIT: Another screenshot. And, sometimes when I start up, I get only a black screen saying [OK]. I can move my mouse around, but nothing helps, except for restarting. Also, my desktop picture doesn't stay the same. Every time I start up Ubuntu it goes back to the standard purple background. They're not very serious problems, but it's all a little annoying. Thanks in advance for your help.

• file:///cdrom/pool/main/k/klibc/klibc-utils_1.5.25-1ubuntu2_amd64.deb was corrupt

  - by curlyreggie

  I guess this is trivial and most commonly asked question, but I'd reiterate it again here as I'm not able to find a correct solution. I'm trying to install Ubuntu Cloud setup on VMWare using the package from http://download.ubuntu.com and have this basic installation setup issue as per the below image. file:///cdrom/pool/main/k/klibc/klibc-utils_1.5.25-1ubuntu2_amd64.deb was corrupt The issue is I cannot continue by skipping this as you know this happens to be the most important setup. How can I fix this? Help is sincerely appreciated.

• nvidia-package in 12.10 somehow not same like in 12.04 resp. X-lib not complete?

  - by dschinn1001

  Not knowing if this has to do with new kernel-update automatic done by ubuntu 12.10 ? it seems that kernel 3.2 in 12.04 has not these problems with nvidia-drivers ? I tried to install the actual google-earth as deb-package with dpkg -i it seems to be no problem, but when I type command: google-earth in terminal, there comes up the report among else: Xlib: extension "NV-GLX" missing on display ":0". Xlib is installed completely and nvidia-driver is de-installed (then reboot) then re-installed again. the report of google-earth stays the same: Xlib: extension "NV-GLX" missing on display ":0". ubuntu 12.04 was working quite good with google-earth. however: bumblebee seems to be taken out of program ? ( or needs to be re-edited ? ) Don't hurry too quick with solution, I can wait !

• Distro that I can load into RAM?

  - by NullUserException

  Is there a modified version of Ubuntu that I can choose to load to RAM on start up? Kinda like the LiveCD, but that can be easily modified (ie: I can install stuff) when I choose to boot from disk. The idea is to install it to a USB drive. I know there's something similar but slax is lacking in many departments. A "full" version Ubuntu would be better. A LiveUSB installation seems to be pretty close to what I want, but apparently I have to choose whether or not it will be persistent by the time I install it. I want to be able to choose that every time I boot.

• Issues running alongside windows and connecting to wireless network

  - by user292247

  Okay so I'm trying to get started with ubuntu but I'm encountering a couple problems: When I boot up the CD and try to install, it does not recognize that I have windows 7 installed and just sees it as unallocated space so the only way I've been able to install it is by wiping the drive which was fine, but it'd be nice to be able to boot either. And secondly, I cannot figure out how to get wireless working. When I try to connect on the initial installation process it tells me to connect to my adapter and just asks for a password. I suspect it could be a driver issue but I wouldn't know where to find it. I have an AR9485 atheros adapter and am attempting to run ubuntu 14.04. Thanks

• Bluetooth no longer working?

  - by user68733

  I am using a Toshiba Portege A600 and have been using Ubuntu for about a year now. When I first installed Ubuntu "10.10", everything worked fine, including bluetooth. I was able to send and receive files. After upgrading to 11.04 and then to 11.10, bluetooth functionality decreased. I was able to view bluetooth devices, but not be able to pair or connect to them. Now, on 12.04, bluetooth is no longer recognised at all. When I open up the Bluetooth settings application, it says "No Bluetooth Adapters found". What is the cause of this, and how can I fix it. I have included the output of sudo lshw. http://pastebin.com/09w0vkfu Thanks!

• Samsung NC10 Broadcom difficulties

  - by simonp

  I am new to Ubuntu/Linux and am stuck already! Any help much appreciated. I have managed to install Ubuntu Maverick 10.10 (from a USB flash drive) on my NC10 which also has Windows 7 on the partitioned drive. But the wireless internet is not working. I have identified the hardware as a Broadcom BCM4313. I have also managed to find that the correct driver is installed (Modaliases for Broadcom 802.11 Linux STA driver). I have followed advice from elsewhere and there does not seem to be any competition from other drivers. I am now stuck and do not have any other internet access on this netbook. Any ideas?

• What is the current frequency of my processor (CPU-Z equivalent)?

  - by Anake

  Is there a ubuntu program like CPU-Z which will show me the actual frequency of my processor? I do a fair amount of scientific computing which leads to me running my programs for up to 10 hrs. To alleviate this problem a little I overclock my CPU. However I can't see what the actual clock of my processor from within ubuntu which means I either have to restart and look at the bios or load into windows. If there was an applet or command line command to find out this information it would be very helpful. Thanks for your help

• Encryption Password help!

  - by Carlos L.

  Ok so let me summarize this up. I encrypted my Home to protect against hackers of course when I first installed Ubuntu. It loaded up the Terminal and was attempting to show me my encryption password incase it ever needed to be used. So I thought "Ehh what the heck, I can find it out later..." So I closed Terminal and went on with the (amazing!) Ubuntu life. But now I am having to install Java JDK 7.0.0.4 onto my computer to ya know, play games and such. But it is asking for my password for the encrypted Home folder but it never gave it to me... HELP!!! Does anyone remember the command for Terminal to give you you're randomly generated Encryption password pop up on the famous purple window? Please give legitimate answer and fast please!

• Address Book Authentication

  - by Gus E

  I just upgraded to Ubuntu 14.04.1 and run Gnome Shell. I am consistently getting a pop up window prompting me for my Gmail address book authentication. The window pops up the moment I type something into gnome shell after hitting the super key. I'm assuming that Ubuntu wants to search my address book for people to include in the search. I have opened up the settings and deleted my account from the online accounts section and rebooted, nothing seems to stop the popup. Where is it getting my email address from? Most importantly, how to I stop this super annoying popup from appearing?

  I am new to Ubuntu. Have installed 12.04 on a slave drive while I migrate.

I do have an old PS/2 KB which I am using at the moment but.......has anyone any ideas on how to get the USB KB reliably connected? Thanks Dave

• laptop suspend broken after latest kernel update

  - by Iestyn ap Mwg

  I ran a software update (Ubuntu 14.04) on my laptop over the weekend, which included an update from kernel 3.13.0-24 to 3.13.0-27, among other things. Today i had to take my laptop to work, so closed the lid and put it in my bag. However, it never went into suspend mode! I tried several times, even rebooting. Finally I tried the previous kernel from the grub menu (reverting back to the -24 one) and suspend works the same as it always had before. Did something suspend related change between the -24 and -27 kernels used in Ubuntu 14.04? I think by only reverting to a previous kernel to temporarily fix it, i've ruled out any other software changes made during the weekend's upgrade.
