• Run windows and ubuntu parallely

  - by user3185902

  I have read about Virtualbox using which we can run both windows and ubuntu parallely, but it seems that for this we have to make one host and install the other one using Virtualbox in it. (Please correct me if wrong) I am already using both ubuntu and windows on my pc (dual boot) and I want to run the already existing ones parallely instead of installing one of them again (don't want to install the softwares again). So, is there a way by which I can do this? Thanks

• What should I do when Ubuntu freezes?

  - by ændrük

  All operating systems freeze sometimes, and Ubuntu is no exception. What should I do to regain control when... just one program stops responding? nothing at all responds to mouse clicks or key presses? the mouse stops moving entirely? In what order should I try various solutions before deciding to pull the power plug? What should I do when starting up Ubuntu fails? Is there a diagnostic procedure I can follow?

• What driver for nVIDIA GeForce MX440?

  - by ubufan

  I have recently installed (clean install) Ubuntu 12.10 on a desktop PC with nVIDIA GeForce MX440 (AGP 8x) and I have problems with Unity. Although I can see the desktop, however i can't see unity bar and icons. So, I decided to install lubuntu-desktop to see the performance. And yes! I choose lubuntu-desktop from Log On screen and the performance is definetely much better and has nothing to do with the aforementioned on unity. The system has native drivers from the Ubuntu installation. I didn't touch anything in xorg configuration. I also remember that I have managed to have the best performance with this graphic card on my previous Ubuntu 9.10 system, by editing some values in /etc/X11/xorg.conf file. But I can't remember that options, because I formatted the / partition! My question is: Which is the most suitable driver for this card, in order to load the unity feature and have better performance on it?

• How can I install another version of Ubuntu on my computer and then uninstall it without messing up my bootup process?

  - by snowguy

  I have Ubuntu 11.10 installed and I am having some problems with it. I'd like to see if the problems are related to some customizations I did. Since one of my problems relate to the slow logout process, I don't want to use the live version. I want to actually install a new version in a separate partition along side my current version and then, after testing that new version and figuring out what I want, just removing the partition and going back to a single version of Ubuntu on this computer. Does anyone know how to do that without messing up my boot process?

• VMWare Workstation 6.5.5 Install Freezes

  - by Android Eve

  I am trying to install VMWare Workstation 6.5.5 (64-bit) on Ubuntu 10.04 (64-bit), but at about 2/3 of the progress bar, it freezes where it says: Installing VMWare Player 2.5.5 Configuring... Interestingly, it is so frozen, that even after I hit cancel, it is still stuck. CPU consumption is at 0% and the command with which I launched the installer is: sudo sh VMware-Workstation-6.5.5-328052.x86_64.bundle Anyone has seen this before? Any idea why this is happening and how to solve this?

• Installing purchased apps by terminal

  - by DoDoGo

  I've been trying to reinstall all my purchased apps on a new machine, and I ran into a problem. Because of the size of them (about 10-12GB in total) and the fact that downloading them is painfully slow for whatever reason (at most 800kB/s), it takes a lot of time (not to mention USC crashing). And then, when I tried to leave them overnight, none of them were installed and everything was at the same spot I left it. Is there anyway to install them via terminal? Like some kind of USC backend were I could just add the archives for apps listed as purchased and then install them via apt-get?

• Problems with dual monitor & resolutions, only in 14.04

  - by theLadder

  I installed Ubuntu 14.04 but i am having weird problems with my dual monitors and the resolutions. I also tried Xubuntu 14.04 and was having the same problem. I have one 32 inch LG TV with 1920x1080 and one monitor with 1280x1024 resolution. When i first start my 32 inch gets 1360x768, if i then try to change to 1920x1080, everythings looks fine and the prompt asking me if i want to keep settings comes up and starts the countdown, but after 2 seconds my computer freezes, and after a few more seconds it reboots itself. However, if i disable my smaller monitor first, i can change to 1920x1080 on my 32 inch without problems, but if i then activate the second monitor the same problem happens again. in Xubuntu 14.04 i can change the refresh rate, if i run the 32 inch at 30hz or 50hz everytying works, but i would like to be able to run it at 60hz. I'm currently running Xubuntu 13.10 without this problem. My graphics card is a ATI Radeon HD 4850. What is causing this problem, grahpics drivers? Kernel? Xorg? And how do i solve it?

• Ubuntu is stuck when it goes to sleep mode in fullscreen

  - by hatter

  If there is a full screen terminal running when Ubuntu goes to sleep, it becomes stuck. This is not the problem with gnome-terminal as sometimes firefox in full screen also causes this problem. With firefox this doesn't happen every time. But with gnome-terminal this happens everytime and as explained in this answer, I use killall command and kill the application. Is this a bug and what can be done to aviod this?

• Momentary freezes about every 60 seconds

  - by Barafu Albino

  I have just switched from OpenSuse to Ubuntu (the only reason is poor repositories - I got tired of installing everything from tar-balls). OpenSuse KDE worked flawlessly. Off-topic OS 7 does too. However, Ubuntu 13.04 after all updates keeps freezing about every minute. The time differs between occasions. It halts just for a fraction of a second, too quick to notice, but music crackles, and compressed video looses its tracks and covers with errors until a scenecut. I don't know what is responsible, the logs are clear. Tried to: change audio card, switched to Nvidia drivers and back, paused all unneeded daemons. Didn't help much. Any ideas where to look? I am experienced in Linux, just new in Ubuntu.

• Cant install Ubuntu. How do you format a Windows HDD

  - by heldeman

  I have an HP 630, and would like to install Ubuntu. All goes well until the point where you have to choose how you want Ubuntu installed. I choose on the whole HDD, I want Windows off the HDD. I press enter and about 5 seconds later the CD tray open and the computer reboots. This happens over and over. How do I format this Window HDD completely to install Ubuntu 13.04. I have tried 3 different CD's and the same thing happens each time.

• get_hosts script being ignored in LTSP setup on Ubuntu 12.04

  - by Shwetav

  We had a home-grown LTSP load-balancer based on LDM_SERVER and get_hosts in Ubuntu 10.04. After upgrading to Ubuntu 12.04, everything worked fine except that get_hosts is being ignored completely. If we put space delimited list of servers as LDM_SERVER in lts.conf, users can choose a server during login and things work fine. Tried both locations below without any luck so far: 1. /var/lib/tftpboot/ltsp/i386/get_hosts 2. /opt/ltsp/i386/etc/get_hosts Any pointers would be greatly appreciated.

• Full screen: launchbar + panel overlaps when showing a dialog box

  - by user85921

  I'm developing a program for 12.04 that will run on full-screen, so I would like to have full control of what appears on the screen. However, when I show another window (possibly a dialog/message box), the Uunity Panel and Launcher appears on the top and left side of the screen. I've experienced this behavior with other applications (Firefox, Gnubg) as well when in full-screen mode. I tried to play with the settings, now my dialog box is hidden from the the taskbar, set to float on it's parent, which is my full screen window. The problem still exists. Is there a way to prevent these panels from showing up, when the new window isn't shown in taskbar, or it's parent is a full-screen window? Or do I need to completely disable them?

• Virtualbox Kernel driver not installed

  - by Cyndi

  I tried to use my Virtual Box and this is the error I received - (I just updated to the new Ubuntu also) and I am VERY new at this Linux OS :) Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

• Synaptics Touchpad v7.4 cannot move while pressing a key?

  - by Miguel30215

  My Synaptics Touchpad v7.4 won't move when I'm using my arrow keys. Everywhere I've looked on the internet is telling me to go to Device Pointer Properties Settings Pointing Sensitivity Palm Check and adjust those Palm Check settings, but that option isn't there and it isn't anywhere else. I've also read about going to something called "Smart Sense" but I didn't see that either. If someone could please help me, I would really appreciate it.

• No video signal during: grub, for a moment when I log out and during shut down

  - by hushs

  When I should see the GRUB menu I only see my monitor writes out this: "No optimum mode. Recommended mode: 1600*1200". If i wait for a short while, ubuntu starts to boot and it reaches the desktop. So I guess there is no video signal during that time, there's the grub menu but i cant see it and after the wait time everything is fine. I have the same problem when I log out for a short moment, before the log in screen is reached. and this also happens when i shut down ubuntu. The VGA is an onboard NVIDIA GeForce 7025. Kinda strange problem, I have no idea how to solve this. Please help :)

• How to install aircrack on Ubuntu 12.04

  - by user287903

  I have downloaded the tar.gz package from the site and then I have extracted using tar -zxvf command as mentioned over there. After that I used sudo apt-get install build-essential then I further installed libssl-dev. Then I changed directory to the aircrack folder. But when I type either sudo make or just make I am getting this same error. I don't know what to do. I have installed the file what they have asked in the error as well. Still the same error is shown. Okay I am not permitted to upload images. The error is : common.mak:85: *** Cannot find development files for any supported version of libnl. install either libnl1 or libnl3.. Stop.

• Distribution upgrade (12.04 -> 14.04 LTS) halted while unpacking/installing packages

  - by Bob Sully

  As the title states...it just stopped unpacking/installing. "Preparing to unpack .../lirc_0.9.0-0ubuntu5_amd64.deb ..." then stopped in its tracks. Everything else is still running. The update manager process is still alive; if I hit ctrl-c, it gives me the warning message about leaving the system in a broken state. Also, if I run top, there is a process called "trusty" which is still running. I have NOT killed either process. lsb_release -a gives: LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch Distributor ID: Ubuntu Description: Ubuntu 14.04.1 LTS Release: 14.04 Codename: trusty I assume that if I try to restart update-manager, I won't be offered the option to upgrade again. Anyone have a way I can get the update-manager/dist-upgrade process to simply finish the upgrade? Thanks!

• dist-upgrade broke my insatll HELP

  - by diefuchsjagden

  so I ran apt-get update; apt-get dist-upgrade the upgrade failed and I lost the gui, I have an encrypted /home drive. When I run apt-get * (any command) I have all kinds of errors mostly missing depends and thats because apparently my network stack is gone. I have no NIC if I run ifconfig. It doesn't even show up with lspci If I were to do a "clean" install of 10.04 LTS which is what I had on my on my build, will I lose all my data? BTW I was just using Ubuntu's default encryption to manage the encryption using my PSWD as the key so if I were to use the same user name and PSWD would my data be accessible? I can see my data from command line, when or if Xorg does start it just loads a basic window with nothing but a black X in the middle of the screen which I can only assume is my mouse cursor but it doesn't move! Reddit /r/linux had some ideas none of which worked was, no help. And apparently /r/ubuntu is full of jerks because all they did was ridicule me. If I can get my install back I probably will be switching back to either Slackware or Gentoo. The Ubuntu forums were of no help they had the same suggestion as /r/linux. I am about to just run my back up script to my back up drives and nuke everything else but I'd rather not.

• How to recover lost files after an install

  - by Gentry McColm

  I'm a newbie learning along the way. I recently installed a 2nd hdd into my ubuntu box. Have one of about 160g which runs ubuntu 12.04. And the new hdd was 1 tb, used for holding videos. I had set up 2nd drive as ext3 I believe. And set up folders on it to hold the videos. Worked great. Also thought I had set it up for auto mount. I was able to read and write on it. Etc. Computer froze, so had to reboot it. When I did, system would not reboot: hung on the Ubuntu screen with 5 dots. I hit a few buttons and the command screen showed up, indicating that my 2nd hdd would not mount. Stopped up whole system. Tried rebooting, no go. Had to reinstall ubuntu on the 1st hdd. Did not apparently touch the 2nd one. Well, when I got it up and running, my 2nd hdd mounted automatically (yeah!), but now I cannot find my videos I already had on it. I had not put any more than about 30g of videos on it, but now when I read its Properties, it says I'm using about 50g. So, I'm wondering if somewhere in that, buried, are my 17 videos. Any help in recovering this? Thanks!

• Data recovery on a Samsung SV1203N HDD

  - by Jim Conace

  Let me start by saying that I am a beginner in Ubuntu, but pretty knowledgeable with Windows. I am having a strange problem trying to recover data from a Samsung SV1203N HDD (120 GiB). I have tried numerous things in both Windows 7 and Ubuntu 12.04 LTS (on a flash drive, an external HDD and a Live CD). This drive has some very important data on it and I am praying some of you Ubuntu geeks can help me get it back. Here's my problem. The HDD is clicking while I am booting, but it stops when I get into Ubuntu or Windows. It refuses to be detected in the bios, so I cant perform any tests on it. I have tried numerous things in both Windows (repair CD, Jumpers, etc.) and Ubuntu (Boot-Fix, GParted, Testdisk, Photorec, forcing a mount, etc.). But it all seems to lead me back to the fact that the drive is not being recognized in the BIOS. I've even tried chilling the drive in the fridge, which worked well for another drive I work on, and I recovered all of the data in Ubuntu flawlessly. I am assuming that since the drive stops clicking when I get into the OS' that there is hope for recovery. I am going to try an IDE/SATA to USB cable, and replacing the Logic Board, but I want to exhaust all other possibilities before I do that. Any help would be greatly appreciated Bye
