• Ubuntu not booting properly

  - by user86998

  I just bought an Asus EeePC with Ubuntu 12.04 installed on it. After turning it on and performing the updates it didn't boot properly and showed a screen saying it was working on low graphics mode, but I wasn't able to get to the GUI. After some searching, I tried renaming xorg.conf.failsafe to xorg.conf using the mv command. After rebooting I got to the Ubuntu GUI but it was stuck to a 800x600 resolution, track pad not working and not detecting my Wi-Fi. After rebooting again it goes straight to console tty1. I'm completely new to Ubuntu and Linux. If some one can give help? I think the best would probably be to reinstall it from scratch, but I don't know how.

• Dual Screens not working nVidia

  - by user91396

  So I'm very much an Ubuntu noob, in fact I just install Ubuntu to my P.C. and I started it up with both my screens plugged into my nVidia's dvi and vga ports and logged in, change the skin to classic gnome, because that's how it was when I last used Ubuntu (8.1), and both screens were working separately. The trouble is that I got a notification saying there was nVidia drivers to be installed, so I install them and restart my P.C., as it told me to, and when I get back on only one of my screens is working and when I go into Displays (All Settings, Displays) it doesn't register my other screen at all, and it calls my working screen "Laptop". I've tried looking through several pages of Google but I see no answer. I did try to find the nvidia-settings to see if that had the answers but sadly I couldn't locate it. Thanks in advance for any help, but please remember, I am very new to Ubuntu.

• Dual-Monitor layout and primary display with Nvidia in Gnome-Shell

  - by java4fun

  I have installed Ubuntu 14.04.1 with gnome-shell version 3.10.4. I can attach a second monitor to my laptop and it is recognized. If I configure it with the nvidia-settings at the right of my laptop then all works fine (the extention of the display works as an extention on the right, not dual). Now what I want is to have the second monitor configured over the laptop-display. When I'm not using gnome-shell, it works correct (I can drag an application from the bottom display to the top normally) but with gnome-shell I have to press Ctrl+Shift+ mouse help, and resize properly the application size. This is for me an enforcing. Is there a way to make that gnome-shell work properly with a bottom/top monitor?

• Ubuntu 13.04 is showing some error while opening my computer

  - by Singh

  Few months before when I was using Ubuntu 12.04 then I found some errors while starting my computer. Due to this problem I had given my CPU to a shop to repair it I don't know what he has done to my CPU but I only know that finally I got my CPU with Ubuntu 13.04. The technician was unable to make any partition and I also think that he had installed 13.04 over 12.04 and so now my computer is showing some error when I'm starting my computer the error is as follows: error: attempt to read or write outside of the disk 'hd0'. grub rescue _ Before showing this error, few times my computer was working very slow. So kindly someone tell me that is there any way by which I can start my computer. Please also tell me that what things I have to keep in mind while using Ubuntu so that in future I find no difficulties(errors) while using Ubuntu.

  - by user208455

  Since the bug described here I am moving LTS distros only, however the current LTS is 12.04, and I`ve seen how ubuntu 13.10 looks like, I know that the unity interface is a WOP but, I wanna know is there any possible way to upgrade unity in 12.04? and btw, after that wipeout ,from the post I was reffering to, that sam stupid (to be polite) thing did windows xp, but now I have shortenned the 500GB ntfs partition to 100 GB and added a 100GB ubuntu partition (for /) and a 200+ GB partition for /home and installed ubuntu 12.04 like that (in "something else"). And after a few minor grub issues everything works perfectly, just like it should be

• Starting Game Programming in C++, where to begin for optimal cross-platform development?

  - by Qasim

  I wish to begin learning game development in C++. I have knowledge in syntax and the console using Visual C++ 2010, however I want to begin programming. My only problem is that I want to be able to support many platforms including Windows, Mac OS, and Linux. As I get better, I also hope I can submit games to XBLIG (or XBLA) and Steam, and even the Google Play Store (But that would take some porting and major redesign of controls). I have looked into c++ and SDL but I have no idea how to get started. I have Visual C++ 2010 installed and I hope I can still use that as other C++ IDEs are quit outdated. Because I want to stick with Visual C++ and SDL (unless there is a better library than SDL), there is not much room for debate but rather how to create projects to support cross-platform development.

• Ubuntu partition won't display on screen

  - by Danny

  I installed ggobi on my MacBook Pro, and it wasn't working right. I looked up some information, and found this site: Gtk Warning: Cannot open display I followed the vague instructions, but I think I just typed export DISPLAY=:0 directly into my terminal (I'm still in my Mac partition at this point). Fast forward a few days, and I try to go into my Ubuntu partition. It only gives me command line options. I remember my reckless input from a few days back, and I'm certain that it is the issue. My problem is that I have no idea how to get my previous display settings back. My Mac partition seems unaffected, but it'd be nice to get back into my Ubuntu partition. My last resort is completely reverting my computer to my most recent backup before I changed it, but if anyone out there knows how to fix this, I'd greatly appreciate it. Thanks in advance.

• How to test 3d acceleration?

  - by HappyDeveloper

  I want to install and test 3d acceleration in Ubuntu 12.

• The field for entering password freeze if no text is enter quickly after i install cinnamon on 12.04

  - by user109162

  Iam a total newbie to Ubuntu . I installed Cinnamon through terminal . The problem is that when i boot up, if i don't enter the password before 1 or 2 minutes the password field will freeze and won't accept any text inputs.The problem was most likely caused by Cinnamon because i guess the problem started after i tried to install some Cinnamon extensions. Please answer in non-technical way as far as possible. I will never go back to Windows whatever be the outcome. Help me stay on to Ubuntu.

• Unable to boot to Ubuntu

  - by nsk

  Just got a new laptop and removed Windows 8 and installed 13.10 using LiveUSB. Initially it was booting to "No boot media" but I was able to resolve it with boot-repair. I realized some of the items I need isn't supported on 13.10, so attempted to install 13.04 instead. Now without LiveUSB, the laptop just boots to "No boot media" but boot repair doesn't seem to be fixing it. Tried going back to 13.10, but no dice. After boot repair it says "Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/grubx64.efi file!". GParted shows sda1 has the boot flag. Using Toshiba Satellite P50. Secure Boot disabled. UEFI enabled. Any help would be highly appreciated. http://paste.ubuntu.com/6366556/

• HP Pavillion laptop screen problems

  - by Liealais Vards Nekas

  Approximately after 4 days when I installed my Ubuntu 10.10 an interesting problem with my laptop screen starts. I had similar problem what you can see in this video - http://www.youtube.com/watch?v=jCYVfGVGWyY&feature=related - but it doesn't happen all the time. The most interesting thing is that, than I had that problem only when I turn my laptop screen in different angle. And this "bad" angle changes by the time, so after about 15 minutes after booting computer I can turn laptop screen in normal position. This is software or hardware problem? I'm using HP Pavillion dv9000.

• Still no wireless after b43 with Dell Inspiron 1525 (Ubuntu 12.04)

  - by DanielleN

  So I followed the instructions here http://ubuntuforums.org/showthread.php?t=1974006 about how to solve this issue. It worked for a bit and then stopped. After doing a modprobe I could at least see my network and click on it but it would not connect (I can always see it if I look under the listed wireless networks under VPN Connections, however). I'm thinking, from what I read at least, the issue might be that my wireless switch was on during those first steps. Do I now have to undo the b43 install and do it again? Or is there something else I could try? I just made the switch to Linux yesterday, so I am hesitant at this point to mess with anything on my own. I should note now that it was installed by someone who knows what they are doing, so we are all good on that front.

• Depending on another open source library: copy/paste code or include

  - by user5794

  I'm working on a large class and started implementing new features that need graphics. I started writing the graphics functions myself, but I know that open source libraries exist that can provide me with this functionality without me having to write it myself. The problem is that I prefer the class to be self-sufficient and not dependent on any other library. If I don't write it myself, I would have to ask the user to make sure a graphics library is already installed (less user-friendly). If I write it myself, I do a lot more work than I have to. I could also copy/paste some of the relevant code into my own class, but not sure about the disadvantages of doing this (it's an open source library that matches my license, so I'm not concerned with legality, just programming-wise if there are disadvantages). So what should I do: copy paste code from the external library write the code myself so it's truly self-sufficient ask the user to download and install another library

• Gnome 3 and compiz, everything works except Explode and Leaf Spread animations

  - by Erik

  I am using 11.10 with Gnome 3, I have installed Compiz, and have got it functioning almost how I want it. I want my windows to Leaf Spread, which seems to work fine for a few minutes after I enable it and restart my machine. However, over the time of a few window closes, I notice that the objects are not showing up little by little until the Leaf Spread just doesn't show at all? This really isn't a big deal, but I'd like things to work properly. Can anyone shed some light on this?

• Why are downloads from Canonical Partners repository so slow?

  - by Sabacon

  If I need Sun Java, Adobe Flash Plugin or anything else that comes from Canonical Partners the package downloads are painfully slow even small sized packages like the Flash plugin, to speed things up I have to go here: http://archive.canonical.com/ubuntu/pool/partner/ to find what I want, download the packages with a download manager (which is usually about 20 times faster than the package manager) and then place them in my /var/cache/apt/archives folder I run the package manager afterwards, as long as the right versions of the packages I ask to install are detected in the /var/cache/apt/archives folder they will be installed immediately. I would like to stop doing this, so I am wondering if anyone else has this problem, what could be the cause and if there is a fix. I am located in the Western Caribbean region. I think it would be helpful to note that all other packages coming from the repository I have selected with synaptic download at acceptable speeds.

• How do I fix this half screen problem?

  - by link1275

  I just installed 12.04, and my entire screen is being displayed entirely on the top half of my screen. The bottom half is always black or some technical garbage from the boot up. To interact with the bottom half of the screen I have to move the mouse over the screen to pull part of the bottom half of the screen on top and vice-versa. Does anyone know how to fix this? Also my computer told me, at startup, to go to here: http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware.

• How do I change the cursor and its size?

  - by Thomas Le Feuvre

  I have recently created an Ubuntu 12.04 partition on my Windows 7 laptop. When installing it, I switched to "high contrast" mode, which has rather large cursors (by large I mean about twice as large and thick as they should normally are). Now I have successfully installed the partition, the large cursors have stuck around even after exiting this high contrast mode, but only when I am hovering over stuff e.g. hovering over text inputs, links, and when resizing windows. All of these cursors are too large. They cursor is only normally sized when the computer should be displaying the normal mouse pointer. Does anyone know how I might go about fixing this?

• Deploying Asp.net MVC web application [migrated]

  - by Pankaj Upadhyay

  I have been trying to find a neat tutorial, guide or step by step instructions for deploying an Asp.net MVC3 webapp but have found nothing so far. Everyone talks about his version of the stroy and different type of MVC versions. Right now, I have build a simple Asp.net MVC web application which i need to deploy on my shared hosting account. In a very simple manner, I need to know which files should i copy. Do i upload everything in my webproject directory to the server including the controller directory, views, models, content and bin directory ?. What about the Global.asax, web.config, packages.config, myapp.publish.xml. In short, I have no idea which files should be uploaded and which should be not. I am sure of one thing that i need few(MVC and Razor dlls) following dlls in bin directory. Just treat me as someone who has never deployed any website NOTE:- I don't have VS SP1 installed and it doesn't install either. Basically i need a manual procedure.
