  • Launcher sometimes appears while full screen in VM (virtaulbox) - how to stop it?

    - by frumbert
    Launcher is great, and it helps me finds stuff. I have the latest release of 12. But when I'm full screen in VirtualBox running another operating system and I hit some key combination I haven't yet figured out, Laucher suddenly grabs keyboard focus. It might be alt-tab, it might be left-control x. I have physically pulled both the windows key and FN key off my laptop because they get in the way, so it's probably not the windows key. You don't know the focus has been stolen because the full screen app (VirtualBox) is still full screen and launcher is in the background. But you're busy typing into a laucher search box, not your foreground application. This is particularly annoying. In my screenshot (taken from a camera, because the built in screen capture program can't capture a screenshot containing the launcher...) the windows VM is the foreground application, but the launcher has come up and is capturing the keyboard: http://imgur.com/SrMRr I would like a foreground full screen app to stay that way. Is there a way that I can keep the launcher but only have it activate (e.g. pop out with its search box) if I physically click the button, not type some random key combination that foreground applications can get confused about? Otherwise I can do without the launcher, because doing my actual work is more involved than just launching programs.

  • How to get the Dash and HUD to appear. (and stop Unity spewing error messages.)

    - by Ubuntiac
    I just installed Ubuntu 12.04 on my wifes Dell Inspiron 1501, which uses an R300 ATI graphics chip. Neither the Dash or HUD appear when pushing the appropriate key. When I try unity --reset & in the terminal, I see that over and over it's spitting out: r300: CS space validation failed. (not enough memory?) Skipping rendering. This is just after starting Ubuntu with no apps open, so I find it hard to believe that just rendering the Dash / HUD is completely blowing out the VRAM. Any suggestions on getting this working? /usr/lib/nux/unity_support_test -p shows OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RS480 OpenGL version string: 2.1 Mesa 8.0.2 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes All sections say "YES"

  • I need beginner help on loading an image (2D). I have an error

    - by Seth Taddiken
    I keep getting a "NullReferenceExeption was unhandled" with "Object reference not set to an instance of an object." written under it. I have all of the images (png) correct with names and added to references. protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); backGround = Content.Load("Cracked"); player1.playerBlock = Content.Load("square"); player2.playerBlock = Content.Load("square2"); }

  • Loading images in XNA 4.0; "Cannot Open File" Problems

    - by user32623
    Okay, I'm writing a game in C#/XNA 4.0 and am utterly stumped at my current juncture: Sprite animation. I understand how it works and have all the code in place, but my ContentLoader won't open my file... Basically, my directory looks like this: //WindowsGame1 - "Game1.cs" - //Classes - "NPC.cs" - Content Reference - //Images - "Monster.png" Inside my NPC class, I have all the essential drawing functions, i.e. LoadContent, Draw, Update. And I can get the game to find the correct file and attempt to open it, but when it tries, it throws an exception and tells me it can't open the file. This is how my code in my NPC class looks: Texture2D NPCImage; Vector2 NPCPosition; Animation NPCAnimation = new Animation(); public void Initialize() { NPCAnimation.Initialize(NPCPosition, new Vector2(4, 4)); } public void LoadContent(ContentManager Content) { NPCImage = Content.Load<Texture2D>("_InsertImageFilePathHere_"); NPCAnimation.AnimationImage = NPCImage; } The rest of the code is irrelevant at this point because I can't even get the image to load. I think it might have to do with a directory problem, but I also know little to nothing about spriting or working with images or animations in my code. Any help is appreciated. Not sure if I provided enough information here, so let me know if more is needed! Also, what would be the correct way to direct that Content.Load to Monster.png given the current directory situation? Right now I just have it using the full path from the C:// drive. Thanks in advance!

    - by firefusion
    I want sub menu's of a verticle menu to expand and collapse when moused over. This is what i've got so far but it goes crazy if you do it to quick as all the animations run at once and on a delay. How can i make sure just one menu expands at a time. I've also set the current_page_item to be open but default and I don't want this to expand or collaspe. <ul> <li class="current_page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a></li> <li class="page_item"><a href="#">Parent Item</a></li> </ul> jQuery('ul.children').hide(); jQuery('li.current_page_item ul.children').show(); jQuery('li.current_page_item').parent().show(); jQuery("li.page_item").hover(function() { jQuery(this).find('ul.children').delay(300).slideDown('slow'); }, function() { jQuery(this).find('ul.children').delay(300).slideUp('slow'); });

  • How can I stop my Jitter physics meshes being offset?

    - by ben1066
    I'm developing a C# game engine and have hit a snag trying to add physics. I'm using XNA for graphics and Jitter for physics. I am trying to split the XNA model into it's meshes, then create a ConvexHull for each mesh. I then attempt to combine those into a CompoundObject, this however isn't working and depending upon the model the meshes are offset by different amounts. This is the code I'm currently using and it gives me: Any ideas?

  • 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?

  • How to make grub stop appearing every time I boot?

    - by Justin Riddiough
    I'm using Ubuntu 12.04 and grub selections appear each time I boot. This happens on both of my computers.

  • How do I prevent Ubuntu gradually slowing down to a stop?

    - by user29165
    I really do not know what is causing the problem of my desktop environment (D.E.) gradually slowing down. It seems to happen in Gnome 3.2, LXDE, XFCE, and KDE. I am running Ubuntu 11.10 and this problem started happening from a fresh install. I have noticed that if I restart Gnome or otherwise re-log-in with any of the D.E.s the speed resets to normal. I don't seem to have and memory leaks that account for it and there are not any processes that are using excessive CPU cycles. Due to the symptoms I am guessing that there is an underlying package that interacts with all D.E.s that is the source of the problem. Just to clarify, in extreme situations, if I let the slowdown continue without a restart of the D.E. my system will finally get to a point where everything, even my clock, freezes. The time over which Gnome slows down (noticeably after 17 hrs) is much less than LXDE, or XFCE but eventually they freeze as well. I didn't mention Unity since I haven't used it enough to verify the problem, but I don't see why it should be different. Just in case this is relevant, I Suspend my computer rather than turn it off. I do this because of the greatly reduced load time and the 17 hrs I stated above is actual up-time, not time where the D.E. is actually active. However, the slow down does not seem to be affected by how long the computer has been in suspend mode. I know that it is possible that this problem is due to an interaction between two or more of the applications that I use and as such it may not be able to be duplicated by others. In the end I am just wondering (a) are other people experiencing this issue and (b) does anyone have some advice on where to start looking for a solution if one is not already known. I am even open to the idea of switching to the beta release of 12.04 if anyone thinks it will solve the problem. Edit: I took a video of my latest freeze that you can watch at http://youtu.be/flKUqUzCmdE, sorry about the audio. Edit: Since that video I checked my memory for errors and tried installing the proprietary video drivers. No memory errors were found and the proprietary video drivers made the display unusable so I had to uninstall them. Any thoughts?

  • How do I stop banshee remembering what's been played?

    - by dunderhead
    How can I prevent Banshee from remembering what files I have played? I really hate the way it keeps surprising me by automatically playing, after the current track, the previous file it had played. I really HATE that. I was just listening to a beautiful piece of music and in a nice mood when Banshee, without asking me, immediately afterwards, started playing a really annoying answerphone message from earlier. My solution so far is to manually delete all files in the playlist, but obviously that's not a long term solution. I cannot find an option anywhere that says "Do not remember my history" (Did I mention I hate the way Banshee plays my files without asking me?)

  • How can I stop pixel seams appearing in adjacent mesh boundaries due to floating point imprecision?

    - by ufomorace
    Graphics cards are mathematically imprecise. So when some meshes are joined by their borders, the graphics card often makes mistakes and decides that some pixels at the seam represent neither object, and unwanted pixels appear. It's a natural behaviour on all graphics cards. How are such worries avoided in Pro Games? Batching? Shaders? Different tangent vectors? Merging? Overlaping seams? Dark backgrounds? Extra vertices at borders? Z precision? Camera distance tweaks? Screencap of a fix that ended up not working:

  • Existent js libs for tileset / map loading and rendering?

    - by ylluminate
    I'm building an rts style overhead tileset game with JavaScript (particularly using Ember.js framework as a base). The map is so large that I'd very much like to be able to load and render the board and layered items in a Google Maps'esque. I'm curious as to whether there are existing libs that would be helpful and already well thought out in these regards vs trying to reinvent the wheel. Are there any such libraries or code examples that would be useful in this area of board / map management?

  • how to get bash to stop escaping $ during tab-completion?

    - by keturn
    I have this on the command line: ln -sf $PWD/wine- and then I hit tab to complete the filename. In earlier versions of Ubuntu, this worked just fine to complete the wine- filename (and as a side-effect $PWD would be expanded at that time). But now it turns it in to ln -sf \$PWD/wine- which isn't what I meant at all and doesn't complete anything as the file does not literally start with $. How do I get completion back to the less broken behaviour? set tells me these are my current settings: BASHOPTS=checkwinsize:cmdhist:expand_aliases:extquote:force_fignore:hostcomplete:interactive_comments:progcomp:promptvars:sourcepath SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitor

  • Possible to stop Adobe DreamWeaver from rewriting 'onclick' to 'onClick'? [closed]

    - by DA01
    I've been giving my dev team grief by checking in HTML edited in DW. It turns out that DW has silently been rewriting all instances of 'onclick' to 'onClick' completely breaking the application in Webkit on us. I've done some digging on Google and this appears to be a bug that goes back to at least 2004. Supposedly it has nothing to do with your code re-writing settings and what triggers it is opening any document that does not contain a Doctype. Few of ours do, given that we're maintaining a framework that's using all sorts of include and dependency files. In all my Googling, I haven't found a fix, though. Has anyone come across one short of swearing off Adobe products forever?* something, btw, that I'm perfectly fine doing...it's just that given the insane IT lockdown on our work machines, we have very few software choices. For now, It's Notepad++ for me.

  • 'mount: error while loading shared libraries: libudev.so.0 : no such file or directory' error while booting

    - by user199551
    I was trying to load a version of CGminer which was returning a libudev type error, and followed a supposed solution here but it destroyed my system (so it seems). I loaded the system in recovery mode from GRUB but all that done was actually tell me what I something is broken, do not know what to do next. I think I somehow associated a libudev.so.0 to 1 or 1 to 0, I am not sure what I did and how to fix it.

  • STOP! Wrong Server!

    - by merrillaldrich
    Some time ago I wrote a post about old-time T-SQL flow control . Part of the idea was to illustrate how to make scripts abort on errors, which is surprisingly convoluted in T-SQL. Today I have a more specific example: how can I check that we are really about to execute in the right database on the right server, and halt if not. Perhaps you’ve connected to the wrong server, or the database you intend to modify doesn’t have the name your script expected. “USE database” is wonderful, but what if it...(read more)

  • Launchctl: how can I configure a service to stop restarting automatically until next reboot?

    - by Andrew J. Brehm
    I have several services set up in launchctl and they all start at boot and restart automatically whenever they stop for any reason. That's great so far. But sometimes I want one of the services to quit and not restart for a while. Is there a recommended way to do that apart from removing the service from launchctl (which also stops it immediately, which I don't want to do)?

  • How to stop Windows Server Standard from booting me while remoted in?

    - by Mike Pateras
    I'm using Remote Desktop connection to connect to a Windows Server box, on which I am an admit. If I'm idle for a few minutes, it locks me out (killing file transfers, which is a problem), and a few minutes after that, it severs my connection. Where can I find the settings that govern these things to stop that from happening? I want it to let me stay connected, regardless if I'm idle.

  • How to stop switchable graphics from switching to high-power GPU when charging the laptop?

    - by Saifallah
    I've an Acer laptop with Windows 7 64 bit and an ATI Radeon HD 6550M Graphics card. Whenever I connect the power to charge the battery it automatically switches to the high-power GPU (ATI) instead of the low-power (Intel) GPU. There's an option in the bios to stop such thing but it makes the GPU runs always on high-power and I can't switch to the low-power GPU. How can I prevent the switchable graphics from automatically using the high-power GPU when charging?

  • How to conform to update-rc.d with LSB standard?

    - by user34881
    This is a migrated question from stackoverflow, as I was told, this is the place for it to be. http://stackoverflow.com/questions/2263567/how-to-conform-to-update-rc-d-with-lsb-standard I have set up a simple script to back up some directories. While I haven't had any problems setting up the functionality, I'm stuck with adding the script to rcX.d dir's using update-rc.d. My script: #! /bin/sh ### BEGIN INIT INFO # Provides: backup # Required-Start: backup # Required-Stop: # Should-Stop: # Default-Start: 0 6 # Default-Stop: # Description: Backs up some dirs ### END INIT INFO check_mounted() { # Check if HD is mounted } do_backup() { if check_mounted; then # Some rsync statements. fi } case "$1" in start) do_backup ;; restart|reload|force-reload) echo "Error: argument '$1' not supported" >&2 exit 3 ;; stop|"") # No-op ;; *) echo "Usage: backup [start]" >&2 exit 3 ;; esac : Using update-rc.d backup start 10 0 6 . I get the following warnings and errors: update-rc.d: warning: backup start runlevel arguments (none) do not match LSB Default-Start values (0 6) update-rc.d: warning: backup stop runlevel arguments (0 6.) do not match LSB Default-Stop values (none) update-rc.d: error: start|stop arguments not terminated by "." The syntax I try to use is the following: update-rc.d [-n] <basename> start|stop NN runlvl [runlvl] [...] . Google wasn't that helpful at finding a solution. How can I correctly set up a script and add it via update-rc.d? I'm using Ubuntu 9.10. UPDATE Using update-rc.d backup start 10 0 6 . stop 10 0 . the error disappears. The warnings about default values persists: update-rc.d: warning: backup start runlevel arguments (none) do not match LSB Default-Start values (0 6) update-rc.d: warning: backup stop runlevel arguments (0 6 0 6) do not match LSB Default-Stop values (none) It even is added to the appropiate rcX-dirs but it still does not get executed...
