• Problem with the installation of VirtualBox

  - by Antonis Grigoriadis

  I am trying to install virtualbox and make it work but it doesn't seem I can. In the image you can seem the output. If I run VBoxManage --version I get: WARNING: The character device /dev/vboxdrv does not exist. Please install the virtualbox-dkms package and the appropriate headers, most likely linux-headers-generic. You will not be able to start VMs until this problem is fixed. 4.3.10_Ubuntur93012 But virtualbox-dkms is already installed and at the latest version. So I tried to reinstall it and i got this: Any help will be appreciated. EDIT: The output after reconfigure (@M.Tarun suggestion): EDIT 2: Also installed the sources as @Hmayag instructed, purged virtualbox and installed it again but I got the same problem.

• AS3 Stage3D Mouse click problem?

  - by Martin K

  I have a problem with Mouse interaction and Stage3D. The only way I found to register to listen to mouse clicks and interact with Stage3D, is to add a mouse eventListener directly to the .stage. However this will result in any time i click anywhere in the flash application the mouse click will fire, even if there is an overlaid 2D menu where the user intended to click. IE I have a 3D application running in the background, which listens to clicks, and I have some floating User Interface elements in the foreground, and ideally if I clicked a button in the foreground, then that would NOT fire a click event that the Stage3D would register. Any idea how to solve this problem?

• Problem with Numlock light and remapping keyboard

  - by ansidev

  I upgraded to Ubuntu 13.10. And there are two problem: Numlock is on. But after I press Ctrl+Space (hotkey for IBus, (default in 13.10 is Super+Space)), Numlock is off and I must press Numlock button twice to enable Numlock. About remapping keyboard, because my keyboard have some broken key, so I am using xmodmap to remap my keyboard (config file for xmodmap is $HOME/.xmodmap). But when I switch keyboard layout (I mentioned above), everything changed to default, and I must run xmodmap .xmodmap to remap keyboard again. When using Ubuntu 13.04, everything is good. How to solve my problems? UPDATE: 1. I am using two keyboard layout: English (US) and Unikey (from ibus-unikey package). 2. If I change key board layout using menu on Unity panel, no first problem.

• Sony bravia screen resolution problem when using Docky

  - by takethemoneyrun

  This is what it looks like: When the laptop (MSI u100) starts up it takes up all available space on the TV screen. About a second after logging in the black bar at the bottom appears. The strange thing is that as you can see the menus can be visible over it, also the dock (Docky app), and any fullscreen application (not maximised, but fullscreen). So what would be the problem here? The source of the problem is the Docky Application. Any ideas?

• Ati Radeon HD 3200 Graphics driver - Installation Problem

  - by samufi

  I have a fresh installation of Ubuntu 12.04 x86 and I am trying to install the proprietary driver for my "Radeon HD 3200 Graphics" video card. I know that there are already many threads about this topic, but I did not find a solution for my problem: For the installation I followed exactly these instructions: What is the correct way to install ATI Catalyst Video Drivers in 12.04 LTS? During the process I faced these problems: I executed ~$ debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases and got: debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Keine Berechtigung Can't exec "libstdc++6": Datei oder Verzeichnis nicht gefunden at /usr/share/perl/5.14/IPC/Open3.pm line 186. open2: exec of libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases failed at /usr/share/perl5/Debconf/ConfModule.pm line 59 (translation of the German parts: "Keine Berechtigung" means: "no permission"; "Datei oder Verzeichnis nicht gefunden" means: "File or folder not found") Because I had no idea if it was a big issue, I just continued: ~$ sudo apt-get install ia32-libs There I got: Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut Statusinformationen werden eingelesen... Fertig Paket ia32-libs ist nicht verfügbar, wird aber von einem anderen Paket referenziert. Das kann heißen, dass das Paket fehlt, dass es abgelöst wurde oder nur aus einer anderen Quelle verfügbar ist. E: Paket »ia32-libs« hat keinen Installationskandidaten (Translation: [...] the package ia32-libs is not available but is referenced by an other package [...] E: package »ia32-libs« has no installation candidate) Once more I went on. The next steps worked quite fine. But when I came to the point: ~$ sudo dpkg -i *.deb There I got A popup message, something like there was a problem with a system application but in the terminal no errors were reported, also the packages seemed to be installed. so now the Ati Catalyst Center works amdcccle but fglrxinfo gave me X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 139 (ATIFGLEXTENSION) Minor opcode of failed request: 66 () Serial number of failed request: 13 Current serial number in output stream: 13 So there is something wrong. (Also there is not the possibility to enable these nice graphical features - the reason why I installed the proprietary driver) Because I worked with a completely fresh Installation I don't know how to fix the problem. If anybody could help I would be very tahnkful! =)

• Kubuntu login problem

  - by Balázs Mária Németh

  I have a problem when trying to login to my Kubuntu 10.10. The login screen shows up, then I type my password, a blank screen is shown with my desktop background picture and then throws me back on the login screen. if I choose to login from console, I can do that, and by typing startx I can log in just fine but in the end I cannot shutdown the computer from the k menu nor will my settings remembered for the next time I log back. I have my home directory mounted from a different partition but I tried to create a new user account and I could log in without any kind of problem. The home directory is not encrypted, at least not to my knowledge. Some log files: Xorg.0.log dmesg.out kdm.log xsession.errors

• Problem with audio sharing between different programs

  - by Lars Borg

  I've been using Linux for quite some time, but until now I've never run into any problems. I also saw the thread "Sound, stopping between multiple programs", but it is referring to a very old version... My problem is that when I run Diablo 3 (using PlayOnLinux) and Skype 4 at the same time, I only get audio from the program that I start first. If I start skype first and then Diablo 3, I have perfekt audio in Skype and sometimes I might hear a faint whisper of the Diablo sounds... This problem started after I changed motherboard to Asus p8z77-v pro with 16GB memory and Intel i7 3770K CPU. With the old motherboard, all this worked just fine. The OS is Ubuntu 12.04. I have only installed Wine, PlayOnLinux, Skype 4, and Diablo 3. All of the latest version, as far as I know. What should I do? What do you need to know, in order to be able to help? Thanks /Lasse

• Live CD boot/installation problem, blank screen - 12.04

  - by traubi

  I'm trying to install ubuntu-12.04-desktop-amd64 from my usb stick. When booting from usb I instantly get a blank screen (with a grey box at the left bottom) I checked the live system with my laptop.works well except it also starts of with a black screen and a grey box at the bottom. I figure the Problem is my geforce gtx 570 since older versions of Ubuntu where only able to boot with xforcevesa and nomodeset. Unfortunately I can't change the boot parameters. I tried the alternate version for a text based install, but it has the same problem. If I press Esc in the alternate I get a message box with two buttons but no text. I would be happy for any advice on this matter

• Intermittent Copy/Paste Problem in RDP

  - by Tara Kizer

  If you use RDP to remotely connect to your servers, you've probably encountered a clipboard issue where copy/paste stops working.  A quick Google search on the problem indicates you can easily fix the problem by logging out/logging back in or killing/restarting rdpclip.exe on the remote server.  Here's an article which covers this topic. But what do you do when copy/paste is intermittent?  It works one second, stops working for 5-30 seconds, and then on its own starts working again.  This is what’s occurring in our new non-production environment.  The DBA team is setting up 16 new physical servers and 5 new virtual machines.  I haven’t found a server where this ISN’T happening.  This intermittent copy/paste issue is driving me crazy!

• Low process priority problem

  - by Svepe

  I have just set Ubuntu 12.04 64bit with Cinnamon desktop and 3.5.0-030500 kernel on my new laptop with IvyBridge i7. I decided to test its performance by running a single threaded CPU-hungry program that I often use for camera calibration. Unfortunately, it ended up running much slower than I have ever expected. After some investigation it turned out that the program priority is automatically changed from normal to low which makes the program even slower. I have also noticed that all user programs such as Skype and Firefox are set to low priority. I tried manually resetting the priority to normal or even very high using the "renice" command, which works temporary until the kernel scheduler (I guess) resets the priority to low. Is this a normal behaviour and how can I overcome the problem with slowing down the execution? P.S. I also tried with the 3.2 kernel, but the problem is still present.

Actually I can do all but only by command line. I try to start Xsession but nothing happens. Actually by typing startx the system stop to works. I read several threads on this topic but I did not find such kind of problem. There is something similar about portege r100 concerning lowgraphics mode but the porblem I have seems to be different because graphics session does not start. Can anyone help me ? Thank you Best

• F# Project Euler Problem 1

  - by MarkPearl

  Every now and then I give project Euler a quick browse. Since I have been playing with F# I have found it a great way to learn the basics of the language. Today I thought I would give problem 1 an attempt… Problem 1 If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. My F# Solution I broke this problem into two functions… 1) be able to generate a collection of numbers that are multiples of a number but but are smaller than another number. let GenerateMultiplesOfXbelowY X Y = X |> Seq.unfold (fun i -> if (i<Y) then Some(i, i+X) else None) I then needed something that generated collections for multiples of 3 & 5 and then removed any duplicates. Once this was done I would need to sum these all together to get a result. I found the Seq object to be extremely useful to achieve this… let Multiples = Seq.append (GenerateMultiplesOfXbelowY 3 1000) (GenerateMultiplesOfXbelowY 5 1000) |> Seq.distinct |> Seq.fold(fun acc a -> acc + a) 0 |> Console.WriteLine |> Console.ReadLine My complete solution was … open System let GenerateMultiplesOfXbelowY X Y = X |> Seq.unfold (fun i -> if (i<Y) then Some(i, i+X) else None) let Multiples = Seq.append (GenerateMultiplesOfXbelowY 3 1000) (GenerateMultiplesOfXbelowY 5 1000) |> Seq.distinct |> Seq.fold(fun acc a -> acc + a) 0 |> Console.WriteLine |> Console.ReadLine   Which seemed to generate the correct result in a relatively short period of time although I am sure I will get some comments from the experts who know of some intrinsic method to achieve all of this in one method call.

• CNAME cross subdomain mapping problem

  - by Ron Ranieri

  I have the exact same problem as this but I don't understand the solution. I have 2 different domain name(with different hosting/provider) domain-one.com and domain-two.com which I want sub.domain-one.com to point to sub.domain-two.com using CNAME. All have been setup and propagate correctly but now when I go to sub.domain-one.com it goes to basic page of the server. If I go directly to sub.domain-two.com the page load correctly. I've tried to add the subdomain using Addon Domains on cPanel but the problem persist.

• Building my first ASP.NET WebForms application problem

  - by user1525474

  Hi I have recently started to learn C#/ASP.NET WebForms and after reading two books I thought I was ready to create my first web application. Problem is I could not have been more wrong. Although I am not quite a beginner as a programmer and have done some programming in Java (a Monopoly game), JavaScript (using jQuery), and PHP (create templates for WordPress), I never really created something that is database driven, and I can't seem to figure where to start. I am very confident in my HTML/CSS/jQuery skills, so that is not the problem. My end goal after becoming comfortable in ASP.NET WebForms is to learn MVC, ADO.NET, and the Entity Framework, and start a career as a .NET developer. I would like if someone could tell me some tutorials that build ASP.NET WebForms applications, such as a blog, so I can see what are the steps in creating an ASP.NET WebForms database driven application. I already have to projects in mind for ASP.NET. One is building a blog and the other building a job board.

• Print Problem: Page Squeezed in Half

  - by iam

  I've just managed to successfully set up my printer (Canon MX320) using the Printing app on Ubuntu 12.04. However the only 1 remaining problem is that each time I tried to print it will only print the file on the top half of the page only: meaning that for some reason, the printer "squeezes" the whole content of each page in the file to fit into the top half of the page only (so the proportion in the print-out is not correct vertically). This happens with every type of file I tried to print (Documents, Images, Web pages). I checked the Printing's setting & properties and couldn't find anything related to this issue yet and I've already made sure to set all the information correct (paper size, source etc.). The Print Preview always display correctly on the screen, but it's only the actual print-out that shows this problem. I also tried with several different types of papers (A4, photos etc.) but the result is always the same: the printer keeps putting the content in the top half of the paper only.

• Ubuntu 11.04 windows XP dual boot problem

  - by Bernie

  I have installed Ubuntu 11.04 direct from installation disk in a separate partition alongside an existing Windows XP installation. Ubuntu operates fine. I can see the old XP file system and the other network computer and access the internet. The problem is when the computer starts I get the boot selection list for Ubuntu or XP; but I am not allowed to select Windows XP (I cannot scroll down the list with tab or arrows keys). This would be fine for me but the computer is used by other people who are only familiar with windows XP at the moment. I have downloaded and run Boot Repair. Below is the link to the resulting data. http://paste.ubuntu.com/1082944/ I hope you can help solve this problem. I look forward to hearing from you. Kind Regards Bernie.
