• How do I install ubuntu 12.04 over windows HP

  - by Cakemix

  I have an HP Desktop AMD 64 6-core processor 10GB RAM 1.5TB HDD and Windows 7 installed. I downloaded the 12.04 ISO and burned to a DVD. I want to install Ubuntu over Windows. I have recovery CD's made in case Ubuntu isn't for me and my family. During the install it says No root file system is defined please correct this from the partitioning table. In the box where I should be able to choose a partition, none are available to choose from, it is blank. I know that HP has decided to use 4 partitions. How do I go about deleting all the partitions using the LiveCD? I've never used GParted before and am a bit lost when it comes to anything to do with partitions.

• Triple Monitor Setup with Nvidia and Compiz

  - by AndrewX192

  I have a triple monitor setup with two video cards on Ubuntu 10.04. I have the monitors and graphics cards currently setup as follows: Nvidia Geforce 210 #1 - 1920x1080 Monitor (Twinview) [Center - Monitor #1] - 1920x1080 Monitor (Twinview) [Right - Monitor #2] Nvidia Geforce 210 #2 - 1920x1080 Monitor (Separate X Screen) [Left - Monitor #3] This works fine, except when I open a program, it shows up in between monitor #1 and #2 - meaning I have to drag it to one screen before I can use the window. Gnome2's gnome-panel also does not work on the twinview setup; it spans between both monitors, but it does not redraw (ex: the clock never changes). In addition, when I maximize an application, it spans both monitors, which is not acceptable. When I enable Xinerama for my setup, gnome-panel no longer spans two monitors, and applications maximize as expected, but compiz does not work, as X11 compositing is not available. The lack of desktop compositing causes problems with dragging windows between screens (redraws take forever). Is there anything I can do to fix these issues without opting for different graphics cards?

• 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.

• How can I fix unreliable Unity startup?

  - by Vagrant232

  When I log in, either Unity loads perfectly or it just doesn't; all I see is my desktop background. Commands don't seem to work and I can't switch to the terminal view. No matter how long I wait, Unity doesn't start. I never had this issue with Oneiric Ocelot. Other GUIs such as GNOME 3.4 don’t seem to be having that issue. I've got MyUbuntu, Ubuntu Tweaks, CompizConf and other tweaking tools installed. Could they be causing the problem? If not, what should I do? I'd really like to use Unity again. Thanks in advance!

• Xubuntu and other Debian based distros slow

  - by William V

  I have a Compaq Presario SR1950NX desktop computer with the AMD64 3800+ processor and 1GB ram and it seems that Ubunutu, Xubuntu and Lubuntu are all laggy. Things seem to be slow such as clicking on menus and opening programs and the UI renders in peices. When using the browser the system slows down considerably. I ran the TOP command and I do notice that xorg hits 30 to 40 percent cpu when running the browsers. I have tried these distros on a spare P4 machine and it is even worse. As long as I don't have a several things open at one time I can manage to get around although sluggishly. I also notice that I can't get debian based distros to install in 64bit (crtc6 failure) only in 32bit. Can anyone tell me what is it that I might be doing wrong? I have an integrated Nvidia card and have tried several of the recommended drivers which sometimes result in no boot screen upon reboot. Thanks

• Is there any simple way to access installed programs?

  - by Anentropic

  Just installed Ubuntu for the first time... Is there any simple way to browse installed programs? On Mac there is the Applications top-level folder... here I see Desktop, Documents, Downloads etc but no Apps? That'd be a good idea, no? (is there some way to create this myself?) On Windows there is the Start menu... Here it seems like I have to click the 'Dash Home' and then I can see 'Recent Apps' ... I can search for them (I'd rather not) ...or I can click the ruler/pencil icon at the bottom and see 'Recent Apps' and click to expand 'Installed Apps' ...ok that's all of them - is it possible to get a straight list view instead of the hard-to-scan wrapped rows? Also, is there any way to get rid of the pointless random selection of 'Apps available for download' at the bottom?

• How to run Virtualbox on bridged and host-only networks?

  - by ril44

  I wish to run VirtualBox with my Ubuntu laptop on the home network (so the desktop PC can access it through the router) and also be able to ssh into the VirtualBox from host on the go (different network or with no internet). Previously, the only network adapter on the VB instance was a 'bridged connection' adapter. This allowed me to access the internet on the guest VB and for the other computers on the LAN + host to access it. However, whenever I took my laptop off the network, I could no longer access the guest from host. I read that I needed to enable a host-only adapter to access it off the network and a NAT adapter is used to access the internet from guest. My question is can I run a host-only adapter + a NAT adapter alongside a bridged network adapter in VirtualBox? I am confused what I would put inside /etc/hosts? Would I put both IP's (host-only and bridged) with the same servername in /etc/hosts?

• How to stop running pidgin at logins and disable window hiding feature?

  - by Behzadsh

  Every time I login into my desktop, pidgin start behind, and sometimes it's bothering me - e.g. when I'm not connected to Internet or when I don't want to be on-line - I check startup application list and there's no pidgin listed. another thing that is very bothering is hiding window feature or what ever it called. assume that you're using MusicTracker plug-in, your status is Busy and you're chatting with someone. when music change, status will change, and then buddy-list will disappear and chat window will minimize. Buddy-list is not important but minimizing chat window when you're chatting is bothering, Is there any way to make pidgin stop that?

• Strange behaviour when screencasting

  - by Luis Alvarado

  Since an update I did yesterday I am not able to screencast any video using Kazam, Recordmydesktop or even ffmpeg/aviconv. After the upgrade to some libraries (A normal update that showed in Update manager) the problem was this: When doing the screencast, scrolling inside an Apps window like Firefox, Chrome or Gedit is not shown. The video only shows the last image it recognized before I started scrolling. For example with Gedit, I have a lot of text on it and when I start to scroll down, the video only shows what I had in the beginning while I listen to myself talk about what is in the rest of the file (Which is not shown in the video). When opening a window, for example again Gedit or Chrome it might not show in the video, it will just show the desktop without the window opened. I do not see any error with dmesg, syslog or others. What can I check to debug this problem?

• Compiz ( or even compositing in general) is not starting up when I login. Solution?

  - by ender.cc

  Whenever I log into a desktop environment, it doesn't seem that compositing is starting. Unity 2D works fine, but when I go to Unity 3D Compiz doesn't start up. I have to type compiz --replace & in terminal every time I login. Another example is when I log into a Cinnamon session, theming support is suddenly gone (although this may be a separate issue). If it helps im using the latest (295.40) NVIDIA drivers. EDIT: I am having exactly the same issue in both cases, upgrading from 11.10 and with a clean installation, in 32 and 64 bits. Related post.

• Can't open Minecraft with java

  - by Shingaling

  I know this has been asked here before, but none of the solutions have worked for me. I have a fresh install of Ubuntu 12.04 on my system and I installed Open Java 7 and I downloaded Minecraft. I right clicked Minecraft went to properties and set it as an executable and then went to open with and Java is no where to be found in the list. I made a new Java desktop file in /usr/share/applications and now when I go to the list Java is there and I set Minecraft to open with it by default but when I open it nothing at all happens. Now how am I supposed to get Minecraft to work?

• 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

• Unable to boot from new SSD after installing from USB

  - by user73725

  I'm using a new SSD with nothing on it. It's installed via USB drive, and boots from USB as well. While in Ubuntu I can see the SSD and other devices. When I install from the desktop (have tried from the boot screen as well), system restarts. It takes me to the boot screen, select boot from first hard disk, nothing, goes right back to boot screen. When I take the USB out, it hangs on "Verifing DMI." If I boot onto the USB I can see the correct files located in the SSD. I have a basic knowledge of computers. Give me any thing you think would help. No other OS's are loaded. Gigabyte ga-k8n-sli 1GB RAM AMD Athlon 64 x2 dual core 3800+ OCZ SSD Agility 3 120GB

• Monitor aspect ratio; Does the difference matter?

  - by Craige

  So, I'm looking ordering myself a new development desktop soon and setting up a PROPER office environment by the end of this year. To boost productivity, I'm going to purchase three new monitors. I find that two just isn't enough when I'm debugging or doing something intensive. That said, I had something pointed out to me the other day that I never really noticed nor cared about before - is the difference between a 16:10 and a 16:9 monitor noticeable when programming? Do you really miss those few extra lines, or is it something that you don't notice at all. I notice HP only seems to sell 16:9 monitors (as far as I have found). Is this becoming something of a new standard with the recent growth and cleaver marketing of of "HD 16:9"? To summarize: Has anybody made the switch from 16:10 to 16:9 (or vise-versa) and actually noticed the difference while programming?

• List of Application indicators

  - by user8592

  I installed Ubuntu 11.04 on one of my systems and I am using Unity interface. Unity is working quite nice so far but i really miss panel applets for net speed, cpu temp, and system monitor. These applets show useful quickinfo. Unlike 10.10, there is no other way to get these infos onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know then please list out any third party indicators with links so that they can be found at one place.

• Beginner's steps to game programming [on hold]

  - by CodeTrasher

  I have graduated from university less than 6 months ago and became a B.Eng in Software Engineering. I have moderate understanding of programming experience from languages like C++, Java and C#. But mostly on simple desktop and mobile applications. I've tried some simple Pong-like games but never finished even the smallest game. I have a couple of nice ideas growing (IMO, at least...) in my mind but don't really know where to begin. 2D is way to go, of course, at the beginning. I just want to hear from more experienced game devs how they started out. Should I make a rough outline of the core idea and mechanics and start working on a prototype of core gameplay? Or should I just practice more by making Pong, Asteroids and that sort of games and get an understanding of those before moving on? Thanks to all!

• How to display time in the top panel?

  - by Mörre

  I thought I already had the time up there in the top bar, and it may have been so in previous Ubuntu versions (don't remember, my Ubuntu laptop is just one of three computers I use). Only that I just noticed - me being someone who never wears a watch, has the cellphone turned off 95% of the time and relying on the computer to tell the time - that there is no time being displayed anywhere, and I had expected it in the top bar on the Unity desktop. I searched around but found no obvious solution, but I'm sure someone immediately knows how I can get my time (back?) into the top bar?

• Best skill set for a max. income entry level job? [closed]

  - by Emmett Gear

  I am interested in getting a bit more experience with programming before I get a job. What languages/skills are currently seeing the highest rates of employment? Are web-developers typically better-paid than desktop software programmers? Do web-developers require a wider skill set? I often see a number of different languages being listed as necessary on web development job applications. Will most potential employers except me to be very familiar with command line Linux? (I'm a Windows guy myself, but I've used Linux in the past). I realize that specialists in dying languages like COBOL or FORTRAN can make a lot of money too, but I am not interested in stuff like that.

• Gnome/X logs off immediately after login -- which logfiles are relevant?

  - by joebuntu

  I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken?

• Error creating an .img file from an .ISO (MD5 verified)

  - by Rob

  I was following the instructions on this website to create a bootable USB flash drive on a Mac: http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx The instruction: hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso does not create a valid file that the disk utility can copy to the USB drive, making installation on a USB drive useless. I've been repeating these instructions for days with no luck. The only thing that does not work is the .ISO to .IMG conversion. Is there a way to download Ubuntu 12.04 LTS 64-but Desktop in a .IMG file already? Unfortunately, my install notebook does not have an optical drive so USB is the only way. Thanks for your help!

  Environment: Lenovo T530 running Windows 7. Have installed Ubuntu 14.04 on a virtual machine using VM Virtual Box. Have installed all the updates from both Virtual Box and Ubuntu. Problem: While in Ubuntu's desktop and other Ubuntu initiated programs, the window is reduced to about 3x4 inches showing in the middle of the rest of my regular Virtual Box window. I am seeing only the upper right hand of the screen output of what I would normally see. Please help. I've seen How do I install Guest Additions in a VirtualBox VM? But, none of these answers works in 14.04.
