  • Problems after upgrading to 14.04 (only background and pointer after login)

    - by fabikw
    After upgrading from 12.04 to 14.04 I could log in to my X session (albeit with really low graphics). While trying to fix the graphics, I managed to break the X session. Now, after typing my password in the unity-greeter, the items disappear and I can only see the desktop background and the pointer. This happens for every user. I can still log in in tty's. How can I solve this? Also, I cannot seem to be able to install nvidia-current as it tries to install nvidia-304 and it depends on old video-abi libraries. Is there a way to tell the package manager that nvidia-current should use a newer version?

  • 5.1 sound in Unity3d 3.5

    - by N0xus
    I'm trying to implement 5.1 surround sound in my game. I've set Unity's AudioManager to a default of 5.1 surround and loaded in a 6 channel audio clip that should play a sound in each of the different audio spots. However, when I go to run my game, all I get is flat sound coming out of my front two speakers. Even then, these don't play the sound they should (front speaker should play "front speaker" right should play "right speaker" and so). Both speakers just end up playing the entire sound file. I've tried looking to see if there is a parameter that I have missed, but information on how to set up 5.1 sound in Unity is lacking (or my google skills aren't that good) and I can't get it to work as intended. Could someone please either tell me what I'm missing, or point me in the right direction? My audio source is situated at point (0, 0, 0) with my camera also being in the same point. I've moved about the scene but the same thing happens as I've already described.

  • Window borders missing - gtk-window-decorator segmentation fault

    - by Balakrshnan Ramakrishnan
    I have been using Ubuntu for about 1 year now and I got a problem just two days ago. Suddenly I started experiencing a problem with the window borders (title bar with close, maximize, and minimize buttons). The problem : The window borders disappear I run "gtk-window-decorator --replace" For like 20 seconds everything is back to normal But it again returns to the problem. I searched over the Internet and found that my problem is similar to what is specified in this bug report: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/814091 This bug report says that the "fix released". I updated everything using the Update Manager, but still the problem remains. Can anyone let me know whether the problem is fixed? If yes, can you please let me know how to do it? I have already tried normal replace/reset commands like unity --reset unity --replace compiz --replace The "window borders" plugin is on in CCSM (CompizConfig Settings Manager) and it points to "gtk-window-decorator". I use Ubuntu 11.10 on an Intel Core2Duo T6500 with AMD Mobility Radeon HD 4300 graphics card. If you need more information, please let me know.

  • Rotating object along bezier curve: not rotating enough?

    - by Paul
    I tried to follow the instructions from the threads on the forum (Cocos2d rotating sprite while moving with CCBezierBy) with Unity, in order to rotate my object as it moves along a bezier curve. But it does not rotate enough, the angle is too low, it goes up to 6 instead of 90 for example, as you can see on this image (the y eulerAngle is at 6, I would expect it to be around 90 with this curve) : Would you know why it does this? And how to make the rotation toward the next point? Here is the code (in c# with Unity) : (I am comparing x and z to get the angle, and adding the angle to eulerAngles.y so that it rotates around the y axis) void Update () { if ( Input.GetKey("d") ) start = true; if ( start ){ myTime = Time.time; start = false; } float theTime = (Time.time - myTime) *0.5f; if ( theTime < 1 ) { car.position = Spline.Interp( myArray, theTime );//creates the bezier curve counterBezier += Time.deltaTime; //compare 2 positions after 0.1f if ( counterBezier > 0.1f ){ counterBezier = 0; cbDone = false; newpos = car.position; float angle = Mathf.Atan2(newpos.z - oldpos.z, newpos.x - oldpos.x); angle += car.eulerAngles.y; car.eulerAngles = new Vector3(0,angle,0); } else if ( counterBezier > 0 && !cbDone ){ oldpos = car.position; cbDone = true; } Thanks

  • Metacity malfunction preventing custom Gnome session from launching?

    - by QuietThud
    When I try to run Metacity in Ubuntu2D(12.04), I get the following message: alisa@ubuntu:~$ metacity Window manager warning: Screen 0 on display ":2.0" already has a window manager; try using the --replace option to replace the current window manager. I get the same message when running Compiz from the command line in 3D (it opens fine through the GUI (same thing for AWN)). I understand that these should be the default managers for the respective sessions. I'm trying to create a custom Gnome session using the following instructions: unity launcher-free session. Here is what I've put into my .session file: [GNOME Session] Name=Custom Unity2D Session RequiredComponents=gnome-settings-daemon; RequiredProviders=windowmanager;panel; DefaultProvider-windowmanager=metacity DefaultProvider-panel=unity-2d-panel FallbackSession=ubuntu-2d DesktopName=GNOME Since I'm having problems identifying my default, and the code refers to Metacity, I figured this may be relevant to my inability to load the custom session (it shows up on my login screen, but won't launch). I tried specifying Metacity as my default manager by adding exec metacity to the .xinitrc file, and I tried running metacity --replace, but neither worked. How do I determine my current default window manager, what should the default be, and how do I re-assign it? Also, please let me know if you think there may be other issues affecting my custom session. I am new to Linux, so list anything you think might be helpful. Thank you!

  • Stuck at enemy movement

    - by Syed
    I am making a TD game in unity, Initially I made all of my enemy movements frame rate dependent say: I had a grid point1 at -22.65 and other at -21.1, diagrammatically: (-22.65) _________(-21.1)_______(-21.1+1.55) ...... so the distance on x axis between two points is 1.55, divided it by 25 jumps with each enemy jump of 0.062 of each frame. On reaching on next point of grid the enemy find again its path. All went fine until I have requirement of FastForward and Pause feature. I used timeScale property of unity but it wont work as they are frame dependent. I also tried double speed of enemy on clicking fast forward button at any time, it has some issues that enemy jumps are now less and it fails to reach on next grid point. Could someone suggest me solution to my problem. Do I need to change the enemy movement code to make it frame independent ?? I need the enemy to reach on the grid specific point I also need later to slow down any one enemy's speed when tower fires on it. Thnx

  • Disable alt + tab moving windows by itself

    - by Lie Ryan
    Whenever I press Alt + Tab , Unity moves the window I'm switching to so that the whole window is inside the screen. This behavior is excruciatingly annoying because I often move a window (usually text editors) partially outside the current screen so I can view another window below it (usually a browser). Every time I Alt + Tab back to the text editor, I'm getting an unnecessary virtual screen switch, and Unity is rearranging the windows behind my back. For instance, here is a browser and text editor on Virtual Screen 1 (top left), note that the text editor is partially outside the current screen: Then I Alt-Tab to the browser (or clicked on it): Next, I Alt + Tab again to get back to the text editor, but Alt-Tab switched me to Virtual Screen 4 (bottom right) because a larger percentage of the text editor window is on virtual screen 4 than in virtual screen 1; and the browser is no longer in the screen. Also note that the text editor window moves from being on the bottom-right to the top-left, which is very disorienting as I can no longer keep track of where any of my windows are since they all keep moving around by themselves.. How do I disable this behavior? I don't want to have any virtual screen switch when Alt + Tab , especially since Alt + Tab does not list windows that is completely not in the current virtual screen anyway.

  • How can I make multiple displays work on my Asus UX32VD?

    - by oKtosiTe
    Original title: Why do I have two trash icons in the Unity Launcher? Whether I run Ubuntu as a live-USB or install it, I always have two trash bins on the Unity Launcher. Both work, and both open the same location. This seems a bit redundant; what could be done about it? Update: Turning auto-hide on made it obvious that I have multiple Launchers showing. With auto-hide off, they simply overlap, making it look like there's a double trash icon, but with auto-hide enabled, I can display one Launcher (and therefore one trash icon) at a time. Still, two are running simultaneously. Second update: This problem appears to be caused by the way Ubuntu handles multiple displays on my Asus UX32VD Ultrabook. Somehow, the laptop display cannot be used while my external display is connected. It is shown in the Displays list, but remains black no matter how I configure it. The external display runs at 1920x1200, the laptop monitor should run at 1920x1080. It therefore becomes obvious that the Launcher that's supposed to run on the laptop display, is actually displayed on the external monitor. Using nomodeset as a kernel parameter as indicated here makes the laptop display inaccessible altogether, detecting the external monitor as the laptop display and making resolutions other than 1920x1200 inaccessible. That is not an option.

  • Why don't windows of the same application behave as they should?

    - by Yuttadhammo
    Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher. Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. (Update: this question details the problem) I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?

  • How can I remove duplicate icons for "launched" java programs in the launcher?

    - by Tim
    When launching java programs (like IntelliJ IDEA and Crashplan) in Natty's Unity launcher, duplicate icons are shown (see image). For IntelliJ I created the .desktop file, for Crashplan the .desktop file is supplied with the application. Is there something that can be changed in the .desktop files (or somewhere else) that can prevent this from occurring? I couldn't find a bug report for unity itself but programs like Gnome-Do/Docky have bug reports and had to make internal changes to their applications to prevent this. In this image the 1st icon is the one created from the .desktop file and the second icon is after launching it. Second icon disappears when closing the application. Custom IntelliJ .desktop file #!/usr/bin/env xdg-open [Desktop Entry] Version=1.0 Type=Application Terminal=false Icon[en_US]=/opt/idea/bin/idea128.png Name[en_US]=IntelliJ IDEA Exec=/opt/idea/bin/idea.sh Name=IntelliJ IDEA Icon=/opt/idea/bin/idea128.png StartupNotify=true Crashplan provide .desktop file [Desktop Entry] Version=1.0 Encoding=UTF-8 Name=CrashPlan Categories=; Comment=CrashPlan Desktop UI Comment[en_CA]=CrashPlan Desktop UI Exec=/usr/local/crashplan/bin/CrashPlanDesktop Icon=/usr/local/crashplan/skin/icon_app_64x64.png Hidden=false Terminal=false Type=Application GenericName[en_CA]=

  • Why will Screenshot not show up in Dash?

    - by Bruce
    I'm relatively new to Ubuntu, and am running into a problem I've not seen before. This is on an Ubuntu 12.04 system. I can't find Screenshot. I'm trying to take a shot of a screen from a web page, go to Dash, type in Screenshot, and nothing shows up. I've done this many times before, but suddenly Screenshot is not found. I downloaded an app called Shutter, it seems to have installed just fine, but like Screenshot, I don't know how to find it. Dash reveals nothing. In Dash, I've noticed that I have no applications showing up in response to a search. For instance, I can type Firefox, and get no results either, even though I'm using Firefox to submit this question. Is there something I can do to get Dash to show applications? Search results show only files and folders, and downloads. I did find one answer on Ask Ubuntu, which gave the following instructions: None of these fixes worked for me. But after more searching: rm ~/.cache/software-center -R worked like a charm. I did need to run: unity --reset & afterwards though, for the changes to take effect within dash, but the software center just started working straightaway. However, when I issued the unity --reset & command, it resulted in an internal error, and I'll have to reboot in order to reset my computer (which fortunately is allowing me to complete this question). So I'm still wondering why applications won't show in Dash, and will appreciate any help.

  • When I shoot from a gun while walking, the bullet is off the center, but when stand still it's fine

    - by Vlad1k
    I am making a small project in Unity, and whenever I walk with the gun and shoot at the same time, the bullets seem to curve and shoot off 2-3 CMs from the center. When I stand still this doesn't happen. This is my main Javascript code: @script RequireComponent(AudioSource) var projectile : Rigidbody; var speed = 500; var ammo = 30; var fireRate = 0.1; private var nextFire = 0.0; function Update() { if(Input.GetButton ("Fire1") && Time.time > nextFire) { if(ammo != 0) { nextFire = Time.time + fireRate; var clone = Instantiate(projectile, transform.position, transform.root.rotation); clone.velocity = transform.TransformDirection(Vector3 (0, 0, speed)); ammo = ammo - 1; audio.Play(); } else { } } } I assume that these two lines need to be tweaked: var clone = Instantiate(projectile, transform.position, transform.root.rotation); clone.velocity = transform.TransformDirection(Vector3 (0, 0, speed)); Thanks in advanced, and please remember that I just started Unity, and I might have a difficult time understanding some things. Thanks!

  • How to get Nvidia graphics working on Sony Z laptop?

    - by projectshave
    I have an older Sony VAIO Z 590 laptop with switchable graphics between Intel and Nvidia GeForce 9300M. It is NOT Optimus. I did a clean install of Ubuntu 12.04. Everything works, but it's using Unity 2D with the Intel drivers. I've tried loading the Nvidia drivers from "Additional Drivers", but it says "this driver is activated but not currently in use". When I run "nvidia-settings", an error window pops up to say "You do not appear to be using the NVIDIA X drivers." "lspci" shows both graphics cards. Let me know if I should add more info. How do I get the Nvidia graphics and Unity 3D working?

  • fresh install of ubuntu 12.04 using usb stick booted into tty1?

    - by croc
    I just installed ubuntu 12.04 alternate for the first time to give it a try using a usb stick burned with UnetBootIn. It installed without a problem. But it booted into a tty1 console without booting into a GUI. after loging into the tty1 console i typed 'unity'. it appeared that the system doesn't have unity desktop !!! How can it be solved ? My installation didn't show any error. Something worth mentioning: 1. during installation i had to choose an option saying 'customize the system to your needs' something like that i don't remember correctly with options 'SSH server','Mail Server', 'Ubuntu Desktop',.....,'Manual selection of packages' etc. I chose 'Ubuntu Desktop'. I haven't encountered something like this in ubuntu 11.04. to do an installation of alternate iso using UnetBootIn i used '12.04_Hdmedia' option of that software and had to change file extension of .ude to .udeb in /pool/main/l/linux that i found in Alternate ubuntu cdrom detect to go around with the cdrom detection problem.

  • How do I create the "Gnome-Desktop-Item-Edit" program's launch icon with root privileges and more?

    - by GanZ
    I personally dont prefer running commands in terminal to achieve a task and prefer apps to execute the job. Creating launcher for apps is one such command where I prefer the gnome-desktop-item-edit application for creating launchers. If the gnome package is installed, just searching "create launcher" opens the app. But, it doesnt serve any purpose, because for starters the application cannot create launchers for various apps without root permission and the location where the apps have to be created. Usually the launcher apps with root permission can be created at /usr/share/applications and without root permission at /.local/share/applications. I dont prefer the latter location as it is vulnerable to deletion. Hence, in order to create the launchers through gnome with root, everytime I am forced to open this through terminal using the below command! $ sudo gnome-desktop-item-edit ~/.local/share/applications --create-new I dont want to open terminal everytime I want to create an application launcher on unity! I am able to lock the "Create Launcher" App in the Launcher, but not with root privileges So I want to be able to create the "Create Launcher" app shortcut on unity with default root privileges and for the app to create the launchers at usr/share/applications by default! Please help! P.S. I dont have enough rep points to add screenshots to help with the question!

  • What differences should I know? I just upgraded to 13.10 from 10.10 [on hold]

    - by test
    I ran Ubuntu 10.10 for a long time because I liked the menu style. The change in GUI with the upgrades drove me nuts but I finally gave in and downloaded Saucy Salamander 13.10 x64. It's a fresh install running as a virtual machine guest in VMWare Workstation 9 on a Windows 7 x64 host. Well it looks like all those icons are still there on the side which I would be OK with if there were some way to bring back my menus. I have no organized way of accessing things now, or do I? That is the purpose for this question, maybe there is some functionality I just can't find but is there. Also all my fine tuning was gone. I used to be able to change DPI but that's gone. I went ahead and installed Unity Tweak Tool via sudo apt-get install unity-tweak-tool but I couldn't find an icon for it after I installed it.. because again no menu. So I did a search for it and found it there. I've changed the font and which side the window buttons appear on which is good enough for now. Anyway... any suggestions you may have for me I'm game. I'm a Windows 7 user primarily but I use Ubuntu every once in a while. I really liked the old style where everything was categorized like for Applications there was Accessories, Games, Graphics, Internet, Office, Sound & Video, Wine.

  • Passing Func<T> to controller constructure when using Unity IoC with MVC, advantages?

    - by user1361315
    I was looking at a sample of how to setup Unity IoC with MVC, and noticed someone who recommended the approach of having the parameters of Func. I believe the advantage is this is kind of like lazy loading the service, if it never gets called it will never get executed and not consume any resources. private readonly Func<IUserService> _userService; public CourseController(Func<IUserService> userService) { this._userService = userService; } Versus a parameter without a Func: private readonly IUserService _userService; public CourseController(IUserService userService) { this._userService = userService; } Can someone explain to me the differences, is it really more effecient?
