• How can i install ubuntu on my ntfs hdd without formatting?

  - by Ridvan Coban

  My hdd is just one partition in ntfs (500gb) and 430 gb is used by my photos/movies/music etc which i never will want to lose. Actually i installed ubuntu on a usb flash drive (using it right now) but it is too slow that way. But my problem is : My computer is damaged ( maybe chipset or but not sure) and none of the windows versions (xp,vista,7) works on my pc. I get blue screen error as soon as windows startup logo shows. But ubuntu just works flawless. That means i cannot use wubi. I wanted to shrink my hdd without losing data (which can be done in windows) but found nothing about that on ubuntu forums. Is this possible? Or install ubuntu on my ntfs filesystem? Note : I don't have chance to backup 400 gbs of data. Sorry for my question if it's written a bit compex. I hope you get the point and someone has an idea ;)

• Fixing restore active desktop on windows xp

  - by Rachel Nark

  I've already tried this: http://answers.microsoft.com/en-us/windows/forum/windows_xp-desktop/windows-xp-will-not-restore-my-active-desktop/f664bfe4-0acd-4b11-8918-eb779bb2cc07 had no luck. All I know is that the computer crashed from a power outage. I've tried clicking the restore button and rebooting. Nothing. What else is there to try? Would like to have the desktop back. It powers on fine. I can login and use windows just fine. Just you get that annoying restore active desktop screen.

• LED Display control software

  - by user978733

  My university bought new big led display from chinese manufacturers. What I want to do is, show some visualizations (like Windows Media Player, Winamp, Itunes ... does) with music. I'd just drag the application window to show on screen But main problem is,The software that controls it (called "Led Vision") doesn't support showing applications' windows: It shows limited types of the files, such as, powerpoint presentation, video files, picture files.. etc. Now the question is, where I can find the visualization video files? something that created in After Effects, looks like that:

• Possible to install Xmonad on Ubuntu separate from Gnome?

  - by Kurtosis

  I just downloaded Xmonad from the repository on my Ubuntu 10.04 box, but when I log out and try to log back in using Xmonad instead Gnome, it doesn't work. I just get the login screen background image and a mousepointer, and nothing else. Right-clicking does nothing, no menus or anything. Key combo's like Ctrl-X, Ctrl-Z, and Ctrl-Alt-Delete do nothing either. Left the computer in this state for 30 minutes while I went to the grocery store, but it was still hung when I returned and I had to hard-reboot it. A Google search returned a few sites showing how to configure Xmonad to work with Gnome, but I'm afraid to try this since I don't want to risk borking my Gnome installation, at least not until I've had a chance to learn Xmonad a bit. Is it possible to run Xmonad independently of Gnome? If so, anyone have any idea what might be wrong and how to fix it?

• Real-time stock market application

  - by Sam

  I'm an amateur programmer. I'd like to develop a software application (like Tradestation), to analyse real-time market data. Please teach me if the following approach is correct, ie the procedures, knowledge or software needed etc: Use a DB to read the real-time feed from data provider: what should be the right DB to use? I know it should be a time serious one. Can I use SQL, Mysql, or others? What database can receive real-time data feed? Do I need to configure the DB to do this? If the real-time data is in ASCII form, how can it be converted to those that can be read by the DB and my application? Should I have to write codes or just use some add-ins? What kind of add-in are needed? How should I code the program to retrieve the changing data from the DB so that the analysis software screen data can also change asynchronously? (like the RTD in excel) Which aspects of programming do I need to learn to develop the above? Are there web resources/ books I can refer to for more information?

• How do I fix the HDMI/DVI display output with Intel HD 4000 Graphics in 12.04?

  - by YumYumYum

  I have an Alienware Dell PC with Intel HD 4000 Graphics (Ivy Bridge) as verified by the output of lspci | grep VGA posted below. 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) The PC only has HDMI and DVI display outputs and using the HDMI output I am only being offered abnormal resolutions. As you can see below it does not even list HDMI1 or DVI1 but just only a fallback. $ export DISPLAY=:0.0 && xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1360 x 768, maximum 1360 x 768 default connected 1360x768+0+0 0mm x 0mm 1360x768 0.0* 1024x768 0.0 800x600 0.0 640x480 0.0 How can I fix this? Does it just need to be configured differently or will I need to use a newer kernel (as Intel Graphics drivers are included in the kernel)?

• Switch monitor configurations on Windows 7

  - by Horst Walter

  I use one of my PCs for flight simulation as well as for home theater. In case one it has 2 monitors attached, and in case 2 (home theater) a HD TV is being used. All 3 monitors are attached at the same time to the graphics card. How could it best switch best between different configurations. In case 1 I'd like to have the configuration with monitor 1/2, alternatively I'd like quickly to switch to another config only with the HD TV as primary screen. A similar question has been asked 6 months back with no full solution yet, so I come up with it again. The comment there of Darius (Windows + P key) is the best so far.

• Is there a way to copy/paste with iterm2 on osx over ssh with tmux and vim?

  - by Aaron Gibralter

  Given I am SSHed into a server and have tmux running, is there any straightforward way to be able to yank into a register in vim and: have that text be available in my tmux clipboard? have that text available in my osx clipboard? I know how to copy/paste in tmux and iterm2 seems to handle passing that onto my osx clipboard. However there are times when I want to yank text in a vim split screen and the tmux copy/paste won't do. Anyone figured this out? Thanks so much!

• vim: how do I keep 10 lines visible when scrolling up to EOF with CRTL-F ???

  - by Gaston

  Hello! I am used to use vi, not vim. What I find annoying in vim is that when you are scrolling with CTRL-F and reach EOF, vim scrolls down to the very last line and put this line on the top of your screen, and you can't see the lines above. You must scroll up a little bit so you can see the context. All this happens with CTRL-F only, not with j or the down cursor key. In vi, you scroll down (with CTRL-F), but when you reach EOF it still show you, say, 15 lines and then the tippical ~. I am using Putty for remote access. How can I config vim to behave like vi in this case? Hope you understand the question. Thank you! Gaston.

• Change popup format for Kopete in Gnome (Ubuntu 10.04)

  - by HorusKol

  After trialling Empathy which was included with Gnome/Ubuntu 10.04 I decided to go back to Kopete since I was losing chat messages. However, for some reason, Kopete is now displaying all popups in a big, ugly window with four options (ok, cancel, view, ignore, or something like that) that actually all seem to do nothing. I tried looking for options in Kopete to change the popup style to the nicer Gnome style one which goes up in the top-right of my desktop, but it doesn't seem to be possible with this release. So I had to resort to removing all popup messages from Kopete to prevent my screen being taking over by a popup requiring action for every incoming chat message. Unfortunately, this now means that I do not get any notifications when people message me - and so I can go a couple of hours without realising that they did. Anyone know how to get the nice, unobtrusive popups working in this version?

• Browser privacy improvement implications for websites

  - by phq

  On https://panopticlick.eff.org/ EFF let you test the number of uniquely identifying bits that the browser gives a website. Among these are HTTP header fields such as User-Agent, Accept, Accept-Language and later perhaps ETAG and If-Modified-Since. Also there is a lot of Information that javascript can get from the browser such as time-zone, screen resolution, complete list of fonts and plugins available. My first impression is, is all this information really usable/used on a majority of all websites? For example, how many sites does really send different content-types depending on the http accept header, or what fonts are available(I thought css had taken care of this)? Let's say of these headers/js functionality on day would be gone. Which ones would; never be noticed they were gone? impact user experience? impact server performance? immediately reimplemented because the Internet cannot work without it? Extra credit for differentiating between what can be done, what should be done and what is done in most situations.

• Proportional speed movement between mouse and cube

  - by user1350772

  Hi i´m trying to move a cube with the freeglut mouse "glutMotionFunc(processMouseActiveMotion)" callback, my problem is that the movement is not proportional between the mouse speed movement and the cube movement. MouseButton function: #define MOVE_STEP 0.04 float g_x=0.0f; glutMouseFunc(MouseButton); glutMotionFunc(processMouseActiveMotion); void MouseButton(int button, int state, int x, int y){ if(button == GLUT_LEFT_BUTTON && state== GLUT_DOWN){ initial_x=x; } } When the left button gets clicked the x cordinate is stored in initial_x variable. void processMouseActiveMotion(int x,int y){ if(x>initial_x){ g_x-= MOVE_STEP; }else{ g_x+= MOVE_STEP; } initial_x=x; } When I move the mouse I look in which way it moves comparing the mouse new x coordinate with the initial_x variable, if xinitial_x the cube moves to the right, if not it moves to the left. Any idea how can i move the cube according to the mouse movement speed? Thanks EDIT 1 The idea is that when you click on any point of the screen and you drag to the left/right the cube moves proportionally of the mouse mouvement speed.

• Reverse bash console text flow

  - by radman

  Hi, This is a bit of a weird question and I'm not sure that there is any easy answer to it but I am very interested in finding a solution. So when I work on a linux machine via a console I find that I am constantly staring at the bottom of the screen, as once you have executed a bunch of commands text fills toward the bottom. Now I find that this is decidedly not good for my neck and it would be far better if instead of scrolling to the bottom, the text would scroll to the top instead. So does anyone out there know if there is a way to reverse the direction text appears in a console? (note that i am aware of the clear command) Example: default behaviour user@machine:~$ command 1 user@machine:~$ command 2 user@machine:~$ command 3 user@machine:~$ __active_prompt__ desired behaviour user@machine:~$ __active_prompt__ user@machine:~$ command 3 user@machine:~$ command 2 user@machine:~$ command 1 Running Kubuntu 10.04 using Konsole I realise this is an odd question, thanks for any help.

• GRUB Error after Deleting Linux Partition

  - by Nironan12

  I was dual-booting with Windows 7 and Windows Vista each taking up half of my hard drive. In Windows 7 I used Easeus Partition Manager to shrink my Windows 7 volume 8GB. On the unallocated space, I installed Linux Mint 8 RC1. After a little bit of playing around with it, I booted in Windows 7, used EPM again and deleted the 8GB Linux partition. I then extended Windows 7 on the 8GB. After restarting my computer, all I get is a black screen and this: GRUB loading. error: no such partition grub rescue> I do not have a Windows 7 disk nor does my computer come with Startup Repair. What do I do?

• Boot ubuntu 12.04 in 3D - nomodeset quiet splash install

  - by rahi

  I would like to enable 3D in Ubuntu 12.04. I recently tried to install ubuntu on a new computer. When the installation was complete and I rebooted the machine, I could only see a blank screen. After some searching, I followed this tutorial which instructed me to boot with "nomodeset" enabled. I choose this on the USB I was installing ubuntu 12.04 from. Fortunately, the ubuntu installation on the new computer was successful. When I tried to change the size of the unity launcher icons, I did not see that option (as I see on my other computer running ubuntu 12.04). I tried installing MyUnity and it told me that the computer I had just installed 12.04 to was running in 2D. To my knowledge. all the software is up to date (as I ran the Software Updater). In addition, when I look for Additional Drivers, I see a message that says "No proprietary drivers are in use on this system". When I look under System Details Graphics, I see the Driver as "VESA:Intel Sandybridge/Ivybridge Graphics. When I hold the shift key on when my machine boots up, and type "e" on the Grub menu, I see the following towards the end, "nomodeset quiet splash $vt_handoff". Does this have anything to do with the plain 2D ubuntu 12.04 experience? Again, what I'd like to do now is get the 3D experience on my new machine running 12.04. Please let me know if you need more information.

• Kubuntu Monitor Out of Range

  - by uncleo

  My X server seems to be faulty, but I don't know why. I had some problems last week with a new motherboard, but they seemed to be resolved. Today, I updated Kubuntu and restarted, but my Viewsonic VX900 LCD monitor shows the splash screen for several seconds, then displays the message "Out of Range" I have tried various kernels in Grub, some in recovery mode, most do the same thing. No key combinations bring up a shell prompt like I expect. The one exception was a very old kernel, that would only mount the file system as read-only, so I can't fix up the xorg.conf file. Is there anything to be done?

• Convert video files for Maemo (Nokia N900) using ffmpeg/mencoder

  - by Vikrant Chaudhary

  I'm a newbie in video encoding so I'm looking for some expert advice. I'm looking to transcode media files with ffmpeg or mencoder (or something other) on Ubuntu for my Nokia N900 running Maemo. I'd prefer mencoder, because of ffmpeg's crazy dependencies. Video output should be AVC/H.264 (probably hardware accelerated on device). Audio output in AAC (should have preferred Vorbis but not supported natively and requires .mkv which is also not completely supported). Output video should retain the original aspect ratio. Resolution of screen is 800x480 (16:10). (Explanation of why-this-value-is-chosen would be really appreciated). Thanks.

• Import SSIS Project in Denali CTP1

  For years Analysis Services has had the ability to take an existing database from a server and reverse engineer it into a BIDS project.  This is extremely useful when all you have is the running instance of the database and the project that created it has long since disappeared.  Reverse engineering has never been a feature of SSIS until now. Let me walk you through the simple steps. The first step is that you obviously have to have a project deployed to an SSIS Catalog.  I will do a video on this soon but in case you can’t wait then my good buddy Jamie Thomson has written it up here As you can see I have a project called imaginatively “Denali1” with one package “Package.dtsx” The next thing we need to do is fire up BIDS and choose the right project type (Integration Services Import Project) Now we just follow the wizard.  We make sure we specify on which server to find the Catalog and in which folder to look for the project. Next the setting are validated and we are greeted with the familiar review screen before the creation of our new project from the deployed project happens Hit Import and away we go The result is just what we wanted.

• Systemd can't start script?

  - by TokyoMEWS

  I have a BASH-script I want to run on start up. My system is running systemd so I created a .service file with whith what I think is the neccessary information: [Unit] Description=My Script After=network.target [Service] ExecStart=/home/myscript.sh [Install] WantedBy=multi-user.target I used systemctl enable to 'register' it an rebooted. On boot I was told my script would be executed, but I could neither see any of the messages ECHO should display on screen nor did it write something to a file, according to what I had written in the script. Additionally, It does not start the application it's supposed to start. Systemctl status tells me that the script has run and exited successfully. Still, the script has no effect. If I run the script from a shell it works perfectly fine. Do any of you know what could be my problem?

• Unable to ping remote server Nagios

• Unable to extend desktop

  - by CSharperWithJava

  I'm trying to hook up my TV to my computer as a gaming/multimedia center but I'm having troubles setting it up. I have a custom built machine running Windows 7 RC. It has an ATI Radeon 4800 video card with 2 dvi output and 1 S-video output. I have an s-video to composite adapter that connects to my tv. (It's an old TV with only Cable, composite, and s-video connections). I can switch the desktop to my TV without a problem, but I can't duplicate or extend my desktop onto it. I've installed the latest drivers and Catalyst Control Center, but it won't let it work any more readily than Windows would. Any suggestions? Would using an s-video cable instead of the adapter change anything? (The only reason I use the adapter is because it came with the graphics card) (Edit) I installed the latest drivers and I can now duplicate the screen (show on one monitor and on the TV), but I still can't extend the desktop.

• Quaternion LookAt for camera

  - by Homar

  I am using the following code to rotate entities to look at points. glm::vec3 forwardVector = glm::normalize(point - position); float dot = glm::dot(glm::vec3(0.0f, 0.0f, 1.0f), forwardVector); float rotationAngle = (float)acos(dot); glm::vec3 rotationAxis = glm::normalize(glm::cross(glm::vec3(0.0f, 0.0f, 1.0f), forwardVector)); rotation = glm::normalize(glm::quat(rotationAxis * rotationAngle)); This works fine for my usual entities. However, when I use this on my Camera entity, I get a black screen. If I flip the subtraction in the first line, so that I take the forward vector to be the direction from the point to my camera's position, then my camera works but naturally my entities rotate to look in the opposite direction of the point. I compute the transformation matrix for the camera and then take the inverse to be the View Matrix, which I pass to my OpenGL shaders: glm::mat4 viewMatrix = glm::inverse( cameraTransform->GetTransformationMatrix() ); The orthographic projection matrix is created using glm::ortho. What's going wrong?

• C# Cursor stuck on busy state

  - by Ben

  So I implemented a fixed time step loop for my C# game. All it does at the moment is make a square bounce around the screen. The problem I'm having is that when I execute the program, the window doesn't allow me to close the program and the cursor is stuck on the busy icon. I have to go into visual studio and stop the program manually. Here's the loop at the moment public void run() { int updates = 0; int frames = 0; double msPerTick = 1000.0 / 60.0; double threshhold = 0; long lastTime = getCurrentTime(); long lastTimer = getCurrentTime(); while (true) { long currTime = getCurrentTime(); threshhold += (currTime - lastTime) / msPerTick; lastTime = currTime; while (threshhold >= 1) { update(); updates++; threshhold -= 1; } this.Refresh(); frames++; if ((getCurrentTime() - lastTimer) >= 1000) { this.Text = updates + " updates and " + frames + " frames per second"; updates = 0; frames = 0; lastTimer += 1000; } } }
