• Graphics card fan is loud (additional graphics card drivers cause problems)

  - by tk4muffin

  Okay this explanation is a bit longer ... but I start at the beginning: I've been using Windows 7 for a very long time, shortly after the release of v12.10 I installed Ubuntu via Windows installer. Everything worked fine but the fan of the graphics card. After a bit of research I found out, that I just had to select a different driver (nvidia-current (proprietary, tested) worked pretty well). This also fixed some graphical bugs when I just logged into my account. Due to my university I got a MSDNAA-Account (allows me to download every Windows OS for free). I downloaded and installed Windows 8. After configuration I installed ubuntu via the Windows installer once again and the first couple launches of ubuntu went well. Suddenly ubuntu didn't launched anymore...caused by some hard-disk errors and had no clue what to do. So I kept working on Windows 8 - unfortunately. After playing around with the new Windows, I put my PC to sleep-mode. I couldn't wake my PC up and it wasn't responding to anything (neither mouse-movement, -clicks or keyboard strokes, nor the power-button and the reset-button worked), so I pulled the plug. Turns out, this was a huge mistake. Somehow the BIOS broke and after restarting a couple of times, the BIOS repaired itself. Neither Windows 8, nor ubuntu where bootable. Now I had to install ubuntu several times, because after rebooting unity was hidden and I didn't know what the problem was and how to fix it. I finally realized that this problem was caused by the graphics card driver, which I've changed to the nvidia-current (This dirver worked fine before my PC "crashed"). So I installed Windows 8 again and after a bit of usage I installed ubuntu once again (via DVD). The booting of ubuntu and windows works fine - so far. But I'm still not able to change the graphics card driver without unity hiding away after restarting the OS. The noisy fan is really disturbing my work... PC Specs: Processor: Intel Core 2 Duo COU E8400 @ 3GHz x2 Memory: 7.8 GB OS type: 64-bit Graphics Card: GeForce 9600 GT Motherboard: Asus P5Q I hope the information given are enough.

• Xcode workspace with Unity3D as a sub-project?

  - by Di Wu

  Let's say we're developing a 2D game with Cocos2d-iPhone and UIKit and CoreAnimation. But we're also considering leveraging the 3D capabilities of Unity 3D. Is it possible that we add the Unity3D-generated Xcode project as a sub-project into the workspace and expose the 3D UI element as some kind of UIView subclass so that the native UIKit and CoreAnimation code could use them without the need to mess up with their underlying Unity3D implementation?

• How do I check user's unlocked achievement and leaderboard scores via GPG plugin

  - by noob

  I need to load user's achievement and their scores from leaderboard in my game. But the Social.LoadScore() and Social.LoadAchievements() both returns a 0 size array in callback. When I checked the implementation in Google Play Gaming's PlayGamePlatform.cs, both the method has this summary - Not implemented yet. Calls the callback with an empty list. So my question is How do I get this data in Unity? Has anyone tried any other method to get the data?

• Multiple Audio listeners in Scene

  - by Kevin Jensen Petersen

  THIS IS UNITY Im trying to make a FPS game over networking, it works fine. But now, when im trying to implement sound, it won't work. My guess would be, to add a Audio listener to the prefab, that gets instansiated whenever a player connects to the server, however the problem about this is that each player's audiolistener have been switched out which the other player(s), so the AudioSource won't play at the player, but at someone else in the game. Any suggestions ?

• Clicking Pidgin message in Ubuntu 13.10 indicator menu doesn't focus on message

  - by Ooberdan

  When I get a message on Pidgin, if I click the notification in the indicator panel, it doesn't bring the message into focus. It highlights that the message has been opened in the Unity dock, but I have to click the dock icon or alt-tab to the window to read the message. Does anyone know a fix so I can view the messages from the indicator notification? (Note: this actually works in 12.04, so I'm assuming it's a bug in the later version). Any help greatly appreciated :)

• Making a surface transparent from blackness of texture

  - by Dan the Man

  I am making a "halo" shader in unity using GLSL. And I've come to a roadblock. What I need to do is take a texture, like the following, and make it transparent according to the darkness of it. And I don't want a cutout, because that cuts it off at a hard edge. This line of code doesn't seem to work. gl_FragColor = texture2D( vec4( _MainTex.r, _MainTex.g, _MainTex.b, _MainTex.a), vec2(textureCoordinates));

• Why does Unity3D crash in VirtualBox?

  - by FakeRainBrigand

  I'm running Unity3D in a virtual instance of Windows, using the Virtual Box software on Linux. I have guest additions installed with DirectX support. I've tried using Windows XP SP3 32-bit, and Windows 7 64bit. My host is Ubuntu 12.04 64bit. I installed and registered Unity on both. It loads up fine, and then crashes my entire VirtualBox instance (equivalent of a computer shutting off with no warning).

• Pidgin script with Python/ Get Focus Signal

  - by Mr Alles

  I am creating a script in Python to integrate Pidgin with Unity (12.04), I've managed to do the counting notifications system using the Launcher API. But I dont know what event or signal is activated when the conversation window gains focus (To clear the message counter). I've tried some of the signals available on the documentation of Pidgin but none of them worked. Is there any GTK(or anything) event that is triggered when the window chat gets focus?

• Compiz crashes after login

  - by T.Kijas

  after I log-in into Unity, compiz effects are disabled and it says compiz crashes. Restart of them usually works, but not every time. After restart of compiz, compiz works without problems, every effect is OK. I tried latest NVIDIA drivers from xorg-edgers, but situation is the same. I tried to delete folder with compiz settings, but it hasn't helped. I use two LCDs, but with only one enabled, the situation is the same. Thank you for suggestions.

• Workspace indicator in the "tray"

  - by Gauthier

  I nearly never use my Unity Launcher bar, so I have it to auto-hide to regain my pixels. The one thing I am missing is the ability to see which workspace I am currently on. What I would like is a little indicator in the upper right corner, that would show me what workspace (viewport) is current. Some similar questions were asked here, but they are all old and for 12.04 or earlier. I want it fixed for my 14.04.

• How to activate a dialogue box on suspend?

  - by don.joey

  I am using 14.04 with unity. Quite regularly it happens to me that I want to shutdown the computer, but in the right corner menu I accidently hit Suspend in stead of Shutdown. Is it possible to add a dialogue box on the suspend menu? So that I don't always have to come back from suspend to finally shutdown afterwards. Or is it possible to make the shutdown button like 3 times bigger than the suspend button?

• Disable “Alt+`”

  - by Albert Francis Lavietta

  How do I disable the keyboard combination of ALT+`. This is NOT the HUD nor in the Ubuntu System Settings. It is NOT in compiz configuration either. (I am NOT trying to disable the HUD's use of the Alt key*) When you press ALT+` on a default unity ubuntu 12.04 install it behaves the same as ALT + TAB. I would like to disable this, because my Windows 7 VM Uses ALT+` to switch languages such as korean or chinese.

• Can I theme the menubar to look different if a window is maximized?

  - by WarriorIng64

  I know you can theme the Unity menubar in GTK+3 using CSS, but is there a way to theme it differently depending on whether a window is maximized? This would be useful for e.g. themes where the menubar should appear standalone in the absence of a maximized window, but then seamlessly blend into the top of such a window when there is one. Preferably, I would like to be able to do this from within the theme files.

• How do I get rid of this monitor error?

  - by Dave M G

  I have an Nvidia card and two monitors. Every time I log in to Unity on Ubuntu 11.10, I get this error: "Could not apply the stored configuration for monitors" I have tried opening nvidia-settings, but none of my experimental alterations to any of the settings has made a difference. I can still use my computer, but it seems to break the themes, icons, and styles so my computer looks like Unix circa 1992, which is a pretty annoying. How do I kill this error?

• Is it possible to use multiple desktop environments on same system?

  - by Kshitiz Sharma

  I am using Ubuntu 12.04. I want to try out KDE and other desktop environments. But I'm not sure if I'll like them enough to switch permanently. I want to be safe and make a transition in a piecemeal fashion. Is it possible to install KDE on Ubuntu and yet not do away with the default Unity shell? Could I install multiple desktop environments and switch between them by tweaking some startup configuration and then rebooting?

• 12.04 - Make Workspaces use the expose feature of compiz

  - by Teddy

  I'm running Ubuntu 12.04 and I just wanted to know if there's a possible way to use the "expose" feature found in CompizConfig Settings Manager as the "Workspaces" icon in the Unity Launcher? I know this feature is great but using Workspaces LAGS A LOT for me, However using Super+S to show up expose works smoothly without lag, is there anyway to use it instead of Workspaces and use expose in replace of it?

• Fusion-Icon does not show up in system tray

  - by Schubibuntu

  I can't find a solution for my problem online: I'm running Unity 2D in Ubuntu 11.10 and want to enable compiz effects. I installed compiz config settings manager, and Fusion-Icon, but when I start Fusion-Icon nothing happens. When I execute it from terminal it stucks at lines like "setting update 'command'" or "setting update 'next_key'" I already set the whitelist for the panel to 'all'. Anyone knows what I'm missing? Thanks in advance!

• How can I stop the panel from showing on an external projector/monitor?

  - by hellocatfood

  In Ubuntu 10.10 (and possibly previous versions), when I connected my laptop to an external source (monitor/projector) and set it not to clone my desktop the display on the external source would not show the (gnome-)panel (just a full-screen desktop with no icons). Since upgrading to Ubuntu 11.04 (using Unity) when I now connect the external source has the panel on there. Is there any way to revert to the previous behaviour in 11.04?

• Ubuntu worldtime desktop clock widget?

  - by ubuntico

  I am aware that in Unity we can add world time by clicking on time bar. However, it's still a list of locations and sometimes it may be hard to quickly find the timezone of interest. Is there any tool which can put a multiple clock instances on the desktop representing each timezone of interest? Similar to the clock in Windows 7. To be more clear, I am not looking for a weather widget, but a simple clock widget so that I can track time in different timezones.
