  • Setting APPMENU_DISPLAY_BOTH for gnome applications does not work on Ubuntu 12.04 LTS

    - by Jack'
    To start the application with the menu enabled in the application and the panel, the following command has to be used: APPMENU_DISPLAY_BOTH=1 appname I recently discovered that this only works for non-gnome applications on Ubuntu 12.04 LTS, i.e. if you replace appname with applications such as gnome-terminal, gedit, evince, empathy, evolution, rhythmbox, nautilus, etc. only global menus will be displayed. However, if you start, for example, gimp or inkscape by using APPMENU_DISPLAY_BOTH, both global and local menus will be shown. The questions is: why is APPMENU_DISPLAY_BOTH not taken into account when starting such gnome applications? P.S. I know how to disable global menus in order to get the local ones (UBUNTU_MENUPROXY trick, removing appmenu-gtk/qt packages, removing the indicator-appmenu, etc.) Thanks for the help!

  • Window manager not loading when gnome-classic starts

    - by Dave M G
    When I boot up or log into gnome-classic (no effects), windows don't have the frame around them that has the minimize and close buttons and all that. After that, there all sorts of issues - for example, when I open a new window, it's in the very top left corner, obscuring the menu on the gnome panel... just a whole bunch of minor annoyances. I can get things working by by loading the compiz fusion icon and then selecting to reload the window manager. Of course this is less than ideal. How do I get the window manager to load automatically? Update: It seems that I get no window manager whenever I load Compiz, even after logging in. So it looks like the problem is more generally with Compiz's window manager.

  • XUbuntu 12.04 sound becomes distorted on ASUS-computers

    - by Slava Fomin II
    On my XUbuntu 12.04 Desktop from time to time audio becomes distorted, not the audio from some specific applications but every possible sounds are very noisy and barely recognizable. Then i go to: Applications Menu Multimedia PulseAudio Volume Control "Configuration"-tab and change Built-in Audio's Profile from my current profile to something else. After that audio becomes normal, until it breaks again and i have to repeat these steps. It's happening on two different computers: one is an ASUS-based Desktop and other is ASUS notebook. Maybe it's related to some common motherboard audio components. Motherboard is: ASUS P8P67 EVO REV 3.0 Netbook is: ASUS EEPC VX6 Any help will be much appreciated = )

  • How do you turn off touch on a Wacom Bamboo CTH-470?

    - by Foxx
    I bought my girlfriend a Wacom Bamboo CTH-470 recently and it is running well after installing wacom-dkms. I have now run into a wall that I don't know how to get around. The touch on the tablet will not turn off. I am running Ubuntu 12.04 Beta 2. I have tried turning the touch off from the wacom settings in the settings menu. The pen and touch both work perfectly fine, it is just that the touch drives her insane when trying to draw in myPaint.

  • What are the so-called "levels" of understanding multithreading?

    - by Dan Tao
    I seem to remember reading somewhere some list of 4 "levels" of understanding multithreading. This may have been in a formal publication, or it may have been in an extremely informal context (even like in a Stack Overflow question, for example). Unfortunately I don't remember who referred to them or precisely what they were. I seem to recall that they were roughly like: Total ignorance Awareness mixed with incompetence Relative competence mixed with fear True understanding My intention is to refer to these levels in a blog post I'm writing, with a reference; but I can't for the life of me remember where I first encountered this list. Brief Google searches have proved unfruitful.

  • How much localizations is too much for a game?

    - by Krom Stern
    We are making an RTS game and we intend to add localizations to all languages our players use. So far we have 16 locales and about 3-4 are being planned. Now some crazy ideas pop up from our community, players ask for "funny text" localizations. We have been already offered a pack that makes it for 1 of our languages. Now I was thinking where should we draw a line between official localizations which we include into the game and unofficial mods that players will have to install on their own? Obviously overcrowding locale selection menu with all sorts of funny locales (LOL-cat, redneck, welsh, medieval, simplified, etc.) for all the languages seems way too much. But is it really? What are the hidden pros and cons of having too much locales and how much is too much?

  • How to use OpenGL functions from multiples thread?

    - by Robert
    I'm writing a small game using OpenGL. I'm implementing basic networking in this game and I'm facing a problem. I have a thread in my client socket class that check for available data, when there are data I raise an event like this : immutable int len = this.m_socket.receive(data); if(len > 0) { this.m_onDataEvent(data); } Then on my game class, I have a function that handle and parse data like this : switch(msgId) { case ProtocolID.CharacterData: // Load terrain with opengl, character model.... Im not able to call opengl functions because my opengl context is created from a different thread. But I really don't know how I can solve this problem, I tried Google but it's really hard to find a solution. I'm using D programming language if it can help.

  • 12.04 - why does the network icon dissapear every time my machine is turned off

    - by Howard Walker
    After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

  • How to keep a team well-trained?

    - by PierrOz
    Hi dear fellows, I'm currently mentoring a small team of 4 junior dev in small software company. They are very smart and often achieve their tasks with a high-quality job but I'm sure they still can do better - actually I have exactly the same feeling for myself :) -. Besides some of them are more "junior" than other. So I would like to find of a funny way to improve their CS skills (design, coding, testing, algorithmic...) in addition to the experience they acquire in their daily work. For instance, I was thinking of setting up weekly sessions, not longer than 2 hours, where we could get together to work on challenging CS exercises. A bit like a coding dojo. I'm sure the team would enjoy that but is it really a good idea? Would it be efficient in a professional context? They already spend all their week to code so how should I organize that in order for them to get some benefits? Any feedback welcome !

  • What should I worry about when changing OpenGL origin to upper left of screen?

    - by derivative
    For self education, I'm writing a 2D platformer engine in C++ using SDL / OpenGL. I initially began with pure SDL using the tutorials on sdltutorials.com and lazyfoo.net, but I'm now rendering in an OpenGL context (specifically immediate mode but I'm learning about VAOs/VBOs) and using SDL for interface, audio, etc. SDL uses a coordinate system with the origin in the upper left of the screen and the positive y-axis pointing down. It's easy to set up my orthographic projection in OpenGL to mirror this. I know that texture coordinates are a right-hand system with values from 0 to 1 -- flipping the texture vertically before rendering (well, flip the file before loading) yields textures that render correctly... which is fine if I'm drawing the entire texture, but ultimately I'll be using tilesets and can imagine problems. What should I be concerned about in terms of rendering when I do this? If anybody has any advice or they've done this themselves and can point out future pitfalls, that would be great, but really any thoughts would be appreciated.

  • Question about JPanel "transition" for Java Swing

    - by user16778
    I want to make like a sort of main menu (in GUI). When the user clicks the start button, the screen transition into another "screen" (JPanel). This image will make it easier to understand. http://i.imgur.com/Cfdry.png Currently, I have a MainMenu extends JPanel and that gets added into a driver class with a JFrame. I can't figure how to switch to another class like Game extends JPanel. So when the user clicks the start button in MainMenu, I want it to somehow hide itself and the Game to show itself. Thanks.

  • Aliasing resellers domain to primary domain

    - by Ashkan Mobayen Khiabani
    I have designed a website that accepts re-sellers and actually the concept of this website is having local re-sellers for each province (or should we say branches). I have designed this website in a way that anybody who has a domain, can point to our website (a record or cname). well most of the website content are the same, the only difference is that re-sellers website doesn't have some items on the main menu and may have some small descriptions of their own branch in some pages. I read that Google may ban websites with duplicate content (or which are significantly similar). I want to know will this be a problem for me? If yes, what else can I do? we have had considered asking our reseller to use iframe that loads our website but wanted that each reseller can have its own SEO and try harder but what I read about this duplicate thing worries me.

  • Boot delay and mouse lag at login after Ubuntu 12.04 update

    - by Roshan George
    I am facing these weird problems after updating Ubuntu 12.04 with apt-get update && apt-get upgrade: It takes too much time to come to the Plymouth theme after selecting Ubuntu from the grub menu. Is it possible to correct this? On the login screen, before entering the password, whenever I move the mouse, it is kind of lagging/stuck. Only after entering the password and pressing Enter, it works normally. I think this may be because of the updated kernel. If so, is it possible to downgrade the kernel to the previous one ? If that is not the reason, what can be the problem?

  • RabbitVCS suddenly stopped working in Nautilus with Ubuntu 11.04

    - by Sander
    A while ago I installed RabbitVCS on Ubuntu 11.04. It then all worked pretty well, but since a few weeks (maybe even more than a month) RabbitVCS suddenly disappeared from the Nautilus context menu. I visited this page: http://wiki.rabbitvcs.org/wiki/support/known-issues and saw some points I could try, but none of them worked out to a working version again. Also this issue Rabbit VCS stopped working after upgrade to 11.10 does not describe the solution for me, so I think it might be something else. I have also tried to reinstall RabbitVCS again from the PPA which was recently updated according to this topic, but no luck. I am still on 11.04 (as I don't like the way Ubuntu is going in newer versions at all) and my Nautilus version is 2.32.2.1 . Is there someone who can help with this one?

  • Rules for Naming

    - by PointsToShare
    © 2011 By: Dov Trietsch. All rights reserved Naming Documents (or is it “Document, Naming”?) Tis but thy name that is my enemy; Thou art thyself, though not a Montague. What's Montague? It is nor hand, nor foot, Nor arm, nor face, nor any other part Belonging to a man. O, be some other name! What's in a name? That which we call a rose By any other name would smell as sweet; So Romeo would, were he not Romeo call'd, Retain that dear perfection which he owes Without that title. Romeo, doff thy name And for that name which is no part of thee Take all myself.  Shakespeare – Romeo and Juliet Act II, Scene 2 We normally only use the bold portion of the famous Shakespearean quote above, but it is really out of context. As the play unfolds, we learn that a name is all too powerful. Indeed it is because of their names that the doomed lovers die. There might be life and death in a name (BTW, when I wrote this monogram, I was in Hatfield, PA. Remember the Hatfields and the McCoys?) This is a bit extreme, but in the field of Knowledge Management (KM) names are of the utmost importance as well. When I write an article about managing SharePoint sites, how should I name it? “Managing a site” or “Site, managing”? Nine times out of ten I’d opt for the latter. Almost everything we do is “Managing” so to make life easier for a person looking for meaningful content, we title our articles starting with the differentiator rather than the common factor. As a rule of thumb, we start the name with the noun rather than the verb. It is not what we do that is the primary key; it is what we do it to. So, answer this – is it a “rule of thumb” or a “thumb rule?” This is tough. A lot of what we do when naming is a judgment call. Both thumb and rule are nouns, albeit concrete and abstract (more about this later), but to most people “thumb rule” is meaningless while “rule of thumb” is an idiom. The difference between knowledge and information is that knowledge is meaningful information placed in context. Thus I elect the “rule of thumb”. It is the more meaningful title. Abstract and Concrete are relative terms. Many nouns (and verbs) that are abstract to a commoner, are concrete to a practitioner of one profession or another and may even have different concrete meanings in different professional jargons. Think about “running”. To an executive it means running a business, to a marathoner its meaning is much more literal. Generally speaking, we store and disseminate knowledge within a practice more than we do it in general. Even dictionaries encyclopedias define terms as they apply to different audiences. The rule of thumb is to put the more concrete first, but within the audience’s jargon. Even the title of this monogram is a question. Do I name it “Naming Documents” or “Documents, Naming”? Well, my own rule of thumb (“Here he goes again!?”) states that the latter is better because it starts with a noun, but this is a document about naming more than it about documents. The rules of naming also apply to graphs and charts, excel spreadsheets, and so on. Thus, I vote for the former.  A better title could have been “Naming Objects” only the word “Object” is a bit too abstract. How about just “Naming” or “Naming, rules of”? You get the drift. One of the ways to resolve all of this is to store the documents in Knowledge-Bases, which may become the subjects of a future punditry. Knowledge bases use keywords to describe their content.  Use a Metadata store for the keywords to at least attempt some common grounds. Here is another general rule (rule of thumb?!!) – put at least the one keyword in the title. Use subtitles. Here is an example: Migrating documents – Screening, cleaning, and organizing our knowledge. The main keyword is “documents”, next is “migrating”, other keywords also appear in the subtitle. They are “screening”, “cleaning”, and “organizing”. Any questions? Send me an amply named document by email: [email protected]

  • Why do I get "No root file system is defined" when I try install in one partition?

    - by Emilio
    The thing is that I have 3 partitions on my computer. /dev/sda1 Type: ntfs (size 104MB; 35MB in use) [This is Windows Loader] /dev/sda2 Type: ntfs (size 144598MB; 64536MB in use) [Here I want to install UBUNTU] /dev/sda3 Type: ntfs (size 105353MB; 20227MB in use) [This my backup partition I don't wan't to delete anything from here, I have all my necessary information] So the problem is when I select "Device for boot loader installation" "/dev/sda2" Pops out: "No root file system is defined. Please correct this from the partitioning menu." How can I resolve this? :)

  • What functional language is most suited to create games with?

    - by Ricket
    I have had my eye on functional programming languages for a while, but am hesitating to actually get into them. But I think it's about time I at least starting glancing that direction to make sure I'm ready for anything. I've seen talk of Haskell, F#, Scala, and so on. But I have no clue the differences between the languages and their communities, nor do I particularly care; except in the context of game development. So, from a game development standpoint, which functional programming language has the most features suited for game programming? For example, are there any functional game development libraries/engines/frameworks or graphics engines for functional languages? Is there a language that handles certain data structures which are commonly used in game development better? Bottom line: what functional programming language is best for functional game programming, and why? I believe/hope this question will declare a clear best language therefore I haven't marked it CW despite its subjective tendency.

  • Why does my computer just keep restarting while trying to install Ubuntu 13.04 (x86) from USB alongside Windows 7?

    - by Sumit Chahal
    I have checked the other questions, but none of them match my problem (the ones that do don't have satisfactory answers). I downloaded the Ubuntu 13.04 iso and burned it to my USB device following the given instructions. I was also able to boot the Ubuntu setup from it by changing the boot sequence so that the USB device is now at the top. But I am only able to use the "trial" version of Ubuntu. Every time I tick "Install Ubuntu alongside Windows" and click "Continue", the computer just restarts and I see the same Try-Ubuntu-or-install-it menu. I have tried pressing any key when that little icon appears at the bottom, but it is not at all helpful. I also read somewhere that I should eject my USB device after I click "Continue", but doing so just makes the computer run Windows 7 instead.

  • navigation menus and SEO

    - by Rodolfo
    I've always have my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

  • How do I rename a mounted Truecrypt volume?

    - by invert
    When I mount the Truecrypt file on my USB drive it shows up as truecrypt1. The volume is FAT, using mtools to rename a volume label involves e2label /dev/sdbx, however truecrypt1 does not map to a physical partition. fdisk -l does not show the volume partition (only the physical USB device), and df -h lists the volume path as /dev/mapper/truecrypt1. Finally, using the Nautilus 'Rename' context action, gives the error: "Sorry, could not rename "truecrypt1" to "towel": Operation not supported by backend". Apparently this can be done in Win, but how can I rename this volume in Ubuntu? As Nicolas said, specifying the mount point names the partition the same. The truecrypt GUI does not remember the mount point I set, so I specify the mount points in a script which I placed in my main menu. #!/bin/bash gksudo truecrypt /media/usbdrive/encryptedfile /media/securedata/

  • Kernel Panic Fatal Machine Check

    - by 0x4a6f4672
    I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-(
