  • Latest Ubuntu stuck on "completing the ubuntu installation"

    - by Joesph Atkinson
    So my issue is after installing 12.10 Ubuntu using wubi.exe on a dedicated parition and rebooting the computer I am given the option to boot ubuntu, as I choose ubuntu I am brought to the "completing the ubuntu installation page" after it hits 0 on the countdown it just sits doing nothing. I left my computer on all day and still the same issue so I know its not just a slow install. Some say its because ubuntu cannot find a video driver for my card (xfx radeon 5770) which if that is the case is there a way i can run the install without it needing to look for drivers?

    - by chiloxsan
    I am trying to use Nvidia Optimus on my laptop by using Bumblebee, I have an Intel Core i5 with an Nvidia Geforce GT 630M. I have followed the instructions on the wiki page at https://wiki.ubuntu.com/Bumblebee, but when trying to run optirun with Firefox (or any other program, like glxspheres), I get the following error: [ 1921.452820] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver [ 1921.452905] [ERROR]Aborting because fallback start is disabled. I have tried googling the issue but I couldn't find any solution that didn't cause more problems. Thank you for your time. Here is my bumblebee.conf: http://paste.ubuntu.com/1333324/

  • Problems with NAT Adapater since upgrade to Ubuntu 12.10

    - by jjesse
    I was running Ubuntu 12.04 w/ VirtualBox installed. I was using the NAT interface to connect to everything. Basically running VBOX for testing some things and a Windows VM for Netflix.. Was back to working in my VMs today and noticed that I was unable to connect to the internet. In the VM settings I'm using the NAT adapter, however I noticed there is no NAT adapter in the Network Settings under Preferences in VBOX. Not quite sure what happened but wonder what is going on? I noticed there are some posts about changes DNSMASQ and configuring a bridge mode, but this worked out of the box under 12.04 and since the upgrade this no longers work. Need some help please

    - by umpirsky
    I want to copy files from one Ubuntu system to another.They are both in local wireless network. I shared entire home dir on one, and tried to copy some files to another.

Here is the example screenshot, it just hangs like this: After I cancel, Nautilus icon in lauchbar keeps progress bar, so I guess there is some problem. What can be the problem?

    - by f.mcleash

  • Upgraded Ubuntu from 12.04 to 12.10 Ati radeon HD 3450 Catastrophe!

    - by minime
    When I had upgraded everything was ready on the screen om my computer and with my 12.04 ubuntu. When I restarted my system, the graphics card was not detected. I was forced to start the computer in low graphics mode, and eventually I had a pink deskop with only my maps, and no other programs at all. What do I do now? I need to recover the pictures on my system so that I can upload them online. I'd done a graphics card test on the terminal initially, and it showed that the card was compatible with unity 3D. I have an ATI radeon HD 3450 and I was running a 32 bit build of Ubuntu 12.04 initially Right now I have a broken install of Linux, with no working graphics card or desktop to start from, so I'm unsure of how to fix this.

  • How do I add more than one command to /etc/rc.local?

    - by Andreas
    I want to add two power saving commands to /etc/rc.local file. This to dissable bluetooth: rfkill block bluetooth And this to reduce screen brightness: echo 3024 > /sys/class/backlight/intel_backlight/brightness Separately added to /etc/rc.local they work but not both of them together like this: #/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. echo 3024 > /sys/class/backlight/intel_backlight/brightness rfkill block bluetooth exit 0 How do I add the two commands to get them properly executed at start-up? Update It turned out to be a timing issue. I fixed it by delaying the execution of the first command thus: (sleep 5; echo 3021 > /sys/class/backlight/intel_backlight/brightness)&

  • Kernel Panic while Installing Ubuntu 12.10 from USB Drive

    - by user100889
    Good evening, I recently looked into installing Ubuntu alongside my Windows. I was able to mount the iso on a USB drive using Universal USB Installer. I verified it with the MD5sum utility and the hash is correct. When installing, I can get to the screen where I choose the boot order, select the USB drive, and then I get to a screen where Ubuntu seems to be 'loading' (purple background with Ubuntu logo and name in the middle). Then, all of a sudden, I get a "Kernel Panic - Not syncing: fatal exception in interrupt" error message. My specs : Intel Core 2 Duo CPU T5850 @ 2.16 GHz / 4 GB of ram / Packard Bell computer from 2007. / Windows 7 Ultimate x64 installed. What should I do now ? Thanks for your help.

  • Chromium web-app creation doesn't work in 12.10?

    - by speter
    If you create an application of a website in Chromium and choose "desktop", a .desktop file is created. In 12.04, you were able to move it to ~/,local/share/applications/ and then start it from the Dash or the launcher. In my fresh 12.10 installation, this doesn't work anymore. I think the line that is misinterpreted is Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/. If you try to run it from a terminal, you get the following result: 20:32 ~ speter Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/ bash: --app=http://buymeapie.com/: Datei oder Verzeichnis nicht gefunden (English: "File or directory not found"). Can anyone explain or knows a workaround?

  • VMware Player and Ubuntu 12.04 - Full Screen

    - by DotNetStudent
    I have installed VMware Player 4.0.2 under Ubuntu 12.04 (Final) and, apart from having to patch the modules, everything went smoothly. However, there's an irritating behavior when toggling full screen mode: toggling full screen (using Virtual Machine Toggle Full Screen or Ctrl + Alt + Return), minimizing the player and maximizing it again changes the resolution of the guest to some strange one and the player gets "nested" between GNOME3's taskbar as every other of Ubuntu's native windows. To switch to full screen again I have to Ctrl + Alt + Return twice. Can anyone please tell me if this is the nromal, expected behavior? Is there any way of "correcting" it? The host operating system is Ubuntu 12.04 (Final) and the guest is Windows 7 (both 64 bits).

  • Is it possible to only allow specific packages updates from a PPA

    - by Luis Alvarado
    Let us say I have added a PPA that has X package that I want but it also has Y package that I do not want to use or receive updates from. How can I, from the same PPA, receive updates for a specific package but deny updates from the same PPA for other packages. A step by step example would be good since this has happened to me in several PPAs that have a particular package I want but also add a whole bunch of others that I do not yet want to update.

  • Help assigning product id for e-commerce site? [closed]

    - by Stanford Sequeira
    I am starting an e-commerce marketplace. I am new to e-commerce, but I am taking it up as a challenge. I will have multiple vendors on my site and they will upload their products through CSV files for bulk upload. However there will be certain popular products already listed in the database, they can add those to their listing (like Amazon for 3rd party sellers). I have no idea how to assign product codes for every product, can you help me out? I'm talking about something like Amazon's ASIN number. Or may be is it possible to let vendors assign their own numbers? How does that work?

  • Map Generation Algorithms for Minecraft Clone

    - by Danjen
    I'm making a Minecraft clone for the sake of it (with some inspriation from Dwarf Fortress) and had a few questions about the way the world generation is handled. Things I want it to cover: Biomes such as hills, mountains, forests, etc. Caves/caverns/tunnels Procedural (so it stretches to infinity... is wrap-around a possibility?) Breaking the map into smaller chunks Moddable (ie, new terrain types) Multiplayer compatible In particular, I've seen things such as Perlin Noise, Heightmaps, and Marching Cubes thrown around. These are like different tools to use, but I don't know when or why I would use them. Are there any other techniques that are useful for map generation? I realize this is borderline subjective and open-ended, but I am looking for some more insight into the processes involved.

    - by George Host
    Hi I have spent aprox 2 days trying to get this to work doing a google searches left and right and I did get it working except for sprite batch nodes. So in my class I am able to load kuwalio_stand.png and I tested kuwalio_walk1.png and 2 and 3 from the FrameCache(). They work for sure 100%. I run this code and it does not animate does anyone else have the same issue with sprite batch nodes? cocos2d::CCSprite * player = Player::create(); player->setPosition(cocos2d::CCPointMake(0.0f,0.0f)); player->setDisplayFrame(cocos2d::CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("kuwalio_stand.png")); player->setTag(PlayerTag); cocos2d::CCAnimation * walk = cocos2d::CCAnimation::create(); cocos2d::CCSpriteFrame * walk1 = cocos2d::CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("kuwalio_walk1"); cocos2d::CCSpriteFrame * walk2 = cocos2d::CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("kuwalio_walk2"); cocos2d::CCSpriteFrame * walk3 = cocos2d::CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("kuwalio_walk3"); walk->addSpriteFrame(walk1); walk->addSpriteFrame(walk2); walk->addSpriteFrame(walk3); cocos2d::CCAnimate * actionWalk = cocos2d::CCAnimate::create(walk); cocos2d::CCRepeatForever * actionRepeat = cocos2d::CCRepeatForever::create(actionWalk); walk->setDelayPerUnit(0.1f); actionWalk->setDuration(10.1f); this->runAction(actionRepeat); // Change camera to a soft follow camera. this->runAction(cocos2d::CCFollow::create(player)); mSceneSpriteBatchNode->addChild(player); // Have the CCNode object run its virtual update function as fast as possible. // Every frame for this layer. this-scheduleUpdate(); Counter example without the sprite batch node... cocos2d::CCSprite * sprite = cocos2d::CCSprite::create("kuwalio_walk1.png"); this->addChild(sprite,0); sprite->setPosition(cocos2d::CCPointMake(60,60)); sprite->retain(); cocos2d::CCAnimation * actionAnimation = cocos2d::CCAnimation::create(); actionAnimation->setDelayPerUnit(0.01f); actionAnimation->retain(); actionAnimation->addSpriteFrameWithFileName("kuwalio_walk1.png"); actionAnimation->addSpriteFrameWithFileName("kuwalio_walk2.png"); actionAnimation->addSpriteFrameWithFileName("kuwalio_walk3.png"); cocos2d::CCAnimate * a = cocos2d::CCAnimate::create(actionAnimation); a->setDuration(0.10f); cocos2d::CCRepeatForever * actionRepeat = cocos2d::CCRepeatForever::create(a); sprite->runAction(actionRepeat);

  • Restricted pathfinding Area

    - by SubZeron
    So i'm triying to create a little "XCOM : Enemy Unknown" like game ,and using the Aron Granberg's Pathfinding-Tool (free version) to handle the "click to move part. i want to add a little trap system where the hero get stuck inside an area, so he will have only the possibility to move inside this trapped area, so far everything is fine however when i click outside the trapped area, the hero try to reach the destination even though the wall will prevents him from reaching it. so my question is, is there any way to restrict the area where the pathfinding system work to the trapped area dynamically. and wich Graph Type is recommended to use in this situation or this kind of Games (Grid Graph/Navmesh Graph/Point Graph). Thank you. image link for explanation : https://dl.dropbox.com/u/77993668/exemple.jpg

  • How to Draw texture between 2 Vector3

    - by Sparky41
    My scenario: RTS combat style, 1 unit fires beam on another unit My problem is i want to draw a flat texture between 2 Vector3 points. I have looked at various Billboarding styles but that doesn't give me a proper solution. I looked at this: http://msdn.microsoft.com/en-us/library/bb464051.aspx is BasicEffect and DrawPrimitives the correct solution just stretch the texture to the distance between point of origin to target? I used the quad class they used but i found this it seemed to inflexible So my question to you is how would i go about this sort of problem? Regards

  • How to make this game loop deterministic

    - by Lanaru
    I am using the following game loop for my pacman clone: long prevTime = System.currentTimeMillis(); while (running) { long curTime = System.currentTimeMillis(); float frameTime = (curTime - prevTime) / 1000f; prevTime = curTime; while (frameTime > 0.0f) { final float deltaTime = Math.min(frameTime, TIME_STEP); update(deltaTime); frameTime -= deltaTime; } repaint(); } The thing is, I don't always get the same ghost movement every time I run the game (their logic is deterministic), so it must be the game loop. I imagine it's due to the final float deltaTime = Math.min(frameTime, TIME_STEP); line. What's the best way of modifying this to perform the exact same way every time I run it? Also, any further improvements I can make?
