• ACER Aspire V5-171 compatibility

  - by JamerTheProgrammer

  Im thinking about buying a V5-171 with an i3 in it. Im worried about secure boot though. I heard some people cant turn it off and it wont work... Im not shy to open it up and replace the hard drive with Ubuntu preinstalled. Im also worried about the wifi working. I have heard its been dropping out for people quite a bit along with also the trackpad not working. I dont mind replacing the wifi stick (if its even possible?) inside. Is the GPU (HD4000 i think) supported in ubuntu with full video accel? Thanks!

• Saving an interface instance into a Bundle

  - by user22241

  All I've have an interface that allows me to switch between different scenes in my Android game. When the home key is pressed, I am saving all of my states (score, sprite positions etc) into a Bundle. When re-launching, I am restoring all my states and all is OK - however, I can't figure out how to save my 'Scene', thus when I return, it always starts at the default screen which is the 'Main Menu'. How would I go about saving my 'Scene' (into a Bundle)? Code import android.view.MotionEvent; public interface Scene{ void render(); void updateLogic(); boolean onTouchEvent(MotionEvent event); } I assume the interface is the relevant piece of code which is why I've posted that snippet. I set my scene like so: ('options' is an object of my Options class which extends MainMenu (Another custom class) which, in turn implements the interface 'Scene') SceneManager.getInstance().setCurrentScene(options); //Current scene is optionscreen

• How to create an auto-grader in and for Python

  - by recluze

  I'm trying to create an auto-grader for one of my beginning programming courses for python. From my online search, I've come to know that it is effectively a unit test framework that tests the student's code rather than production code but I'm not really sure how to structure the flow of the program. Can anyone please provide a strategy for submission of code by students and automating the whole process of marking? For instance, how would the student code be submitted and then stored/structured on disk, how would the grades be stored/reported? I'm only looking for a broad strategy and will try on my own to fill in the blanks. (I asked this on stockoverflow.com initially but it's considered as off-topic and I was suggested to ask here.)

• Unity 3D not Working on Acer D270 w/ Intel GMA 3600

  - by amol.kamath

  I recently bought myself an Acer Aspire One D270 with the GMA 3600 graphics chipset thinking I would get some lovely graphics. However, I am stuck using Unity 2D and I cant figure out how to enable 3D. None of the fixes I have found so far have worked. Another effect of this is that I cant change the backlight brightness. So whenever I open the lid, looking at the screen is like staring into the sun. Is there a driver for it in the works? Does the 3.4 kernel support the chipset and most of all is there a way to fix this? Please help

• How to set up an environment for android app development?

  - by The Dark Knight

  I have been researching for sometime now regarding the process to install android sdk and associated tools . After visiting Android Developers page, i first installed the android sdk and then installed eclipse plugins for my indigo version from the install softwares options.However, it is mentioned in the developers page : Download the Android SDK. Install the ADT plugin for Eclipse (if you’ll use the Eclipse IDE). Download the latest SDK tools and platforms using the SDK Manager. I have downloaded the sdk and installed the adt plugins for eclipse.I just need to point the eclipse towards the location of the sdk. However, i am stuck at the last step which is asking me to download the latest tools using the sdk manager. The manager interface pops up and i see a lot of options there. I don't know which ones i must select and install. If some one can help me out here and tell me which options to choose and install(if possible, with a screen shot), it will be very beneficial for me.

• What would I do to figure out why Suspend sometimes crashes?

  - by Isaac

  Something is causing suspend crash occasionally. When it does crash, the system freezes with a black screen and stays on, not suspending. This makes me have to hold the power button until the system shuts down. One setting difference I have from most people is, I don't use the option that lets you suspend when the laptop lid is closed. So opening and closing the laptop lid has no actions. I like to press suspend manually. Could this preference change be the cause? How can I start looking for what's causing the crash, since the crash doesn't display errors?

• SH404SEF URLs in Joomla 1.5

  - by Tao Bellamine

  I have two modules to play with urls, the global configuration module and the sh404sef module. The global config is set to "Sef urls: YES" and "mod rewrite enabled: YES" and the sh404sef is set "url optimization: NO". My problem is, even with "Sef urls" set in the global config, my urls still don't seem to be that "user friendly" so I turn on the "Url optimization" using the sh404sef module, and I get better descriptive urls. However, the problem I inherit from doing this is that my dynamically populated chronoforms get messed up (only the chrono forms, other forms are fine); These forms are now showing up at the homepage instead of their own reserved page. Here's an example: Old form "GOOD" url: http://www.mycraftwork.com/index.php?option=com_content&view=article&id=94 New optimized "BAD" URL: http://www.mycraftwork.com/handthrown-pottery/alladin-teapot/index.php?option=com_content&view=article&id=94 Any help would be GREATLY appreciated! I can even turn the sh404sef on and off if some people are interested in seeing the issue LIVE. Thanks!! Tao Bellamine

• VPN disconnected: resolv.conf not refreshed

  - by cwall

  I connect to VPN using vpnc. When VPN disconnects, either via time out or the session limit is reached, VPN is terminated, but resolve.conf continues to contain references to my VPN network. resolv.conf before VPN is connected: nameserver 127.0.0.1 search mylocalnetwork resolv.conf after VPN is connected and remains once VPN is lost: nameserver X.X.X.X nameserver X.X.X.Z nameserver 127.0.0.1 search internal.mycompany.com mylocalnetwork In 10.04, when VPN lost, I'd run this script to refresh resolve.conf: 7$ cat bin/refreshResolvconf.sh #!/bin/bash #if [ -e /etc/resolvconf/run/interface/tun0 -a "`pidof vpnc`" == "" ]; then /sbin/resolvconf -d tun0; fi if [ -e /etc/resolvconf/run/interface/tun0 -a "`pidof vpnc`" == "" ] then /sbin/resolvconf -d tun0; echo "Refreshed resolv.conf" fi But, resolveconf changed in 12.04 changed, so this script is no longer applicable. To resolve, I manually edit resolve.conf or turn off/on my connection via "gnome-control-center network". Anyone else have the same problem? How can resolv.conf be updated post-VPN disconnect?

• No boot record when installing 13.04 from USB on WinXP

  - by Phil Leslie

  I'm replacing WinXP with 13.04 on an older PC using wubi.exe on a USB stick. I had no problem changing the BIOS on another system that was a bit newer but when I change the settings on the older PC to boot from USB, I get a DOS message saying "Searching for boot record...Not found" & asked to try again. I don't have the ability to boot from a live CD so is there a reason why I can boot from a USB on a newer computer but can't from an older one? Both have options to choose to boot from USB, but the older one can find no boot record. The system was built on 12/13/01 by American Megatrends. Since I don't have enough "reputation points" to post the screen shot image, you can see it at http://img.photobucket.com/albums/v633/boonevillephil/1029131748-00.jpg.

• HP 510 laptop doesn't suspend when I close the lid

  - by Yuri

  I have an HP 510 laptop with Ubuntu 12.04. I have all the correct settings for suspending when the lid is closed, as far as I can tell, so I think it's a problem with detecting the event. The way it "should" be detected, from what I can see, is a little hardware switch that is pushed when the lid closes. This switch manually puts off the backlight, and sends the suspend signal. All I can think is that the signal isn't being properly interpreted. Can anyone suggest a fix? Update: I tested whether the button was actually working based on the suggestion by josinalvo, and I found that in the directory /proc/acpi/button/lid/ there is no LID directory. There is, however, a C1CF folder, and in it is a state file. When using the this file instead of ID, I discovered that, no, when I close the lid, the state does not change.

• How do I prevent useless content load on the page in responsive design?

  - by Ícaro Leandro

  In responsive design, elements are hidden in the page with @media queries and display: none in CSS. Ok. In my design however browsers that have less than 800px in width should avoid loading some content at all. When accessed with on a device with more than 800px of screen, the page loads fully. In mobile devices or even on desktop with less than 800px of width some content is hidden. I want to make the page load faster for low-resolution devices and avoid loading chunks of content that the user will never see. How can I go about this?

• GNOME 3.4 released, with smooth & fast magnification

  - by Peter Korn

  The GNOME community released GNOME 3.4 today. This release contains several new accessibility features, along with a new set of custom high-contrast icons which improve the user experience for users needing improved contrast. This release also makes available the AEGIS-funded GNOME Shell Magnifier. This magnifier leverages the powerful graphics functionality built into all modern video cards for smooth and fast magnification in GNOME. You can watch a video of that magnifier (with the previous version of the preference dialog), which shows all of the features now available in GNOME 3.4. This includes full/partial screen magnification, a magnifier lens, full or partial mouse cross hairs with translucency, and several mouse tracking modes. Future improvements planned for GNOME 3.6 include focus & caret tracking, and a variety of color/contrast controls.

• What are the packages/libraries I should install before compiling Python from source?

  - by Lennart Regebro

  Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). Off the top of my head I can remember these: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) But I know there are many more. Please tell me and I'll update.

• Recovering data from hard disk after an accidental Ubuntu reinstallation

  - by Saurabh Agarwal

  My computer got wiped accidentally due to a fresh Ubuntu installation. Since the drive contains very important data and codes, it would be really great if the same could be recovered. It is a 2TB hard drive which had Ubuntu 10.10 earlier. It now has a Ubuntu 12.04 installed on it (which I understand occupies ~4GB). The machine has been powered off since. The installation was done using a usb with the option where the previous ubuntu installation is removed. Since installation doesn't take a lot of time, I'm inclined to think that the disk wasn't completely formatted and that most of the data is still there. I have no experience with recovery and hence a detailed explanation is very helpful. NOTE: I can arrange an additional 2TB hard disk for copying data. My computer has a fast internet connection and I have other computers connected to the network which I may use to access the previous one as well.

• 12.04 BCM4312 and aireplay-ng/airodump-ng

  - by Haxornator

  First off, I've read through all of the posts regarding BCM4312 on the forums but haven't been able to get any help. Basically I have a Dell Inspiron 1564 which I've installed 12.04 on and for the most part everything works fine but now that I'm trying to use more in depth utilities such as aireplay and airodump I'm coming across what I believe to be a driver problem thats not allowing compatibility for these programs. Does anyone out there have any suggestions how to resolve this? This is the error I receive: root@Haxornator:~/aircrack/aircrack-ng-1.1# airodump-ng eth2 ioctl(SIOCSIWMODE) failed: Invalid argument ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make sure RFMON is enabled: run 'airmon-ng start eth2 <#' Sysfs injection support was not found either.

• Can't disable Alt + mouse buttons combinations

  - by Andrey

  I've already searched through the questions, and didn't find the same question as I want to ask. I'm working in blender and there are some combinations that I am used to and remapping them in blender would be the last resort, not the first. I have tried to disable Alt+LMB and Alt+RMB actions in ccsm, I've tried to do this in dconf or gconf editors as well, but nothing helped. As soon as I close the editors or get back to the main screen of ccsm, these combinations are enabled again. So, for example, instead of selecting an edge loop in blender with Alt+RMB, I get this goddamn menu offering me to move the window to another workspace, etc. I really don't need this function, so I'd rather switch it off instead of remapping the hotkeys I'm used to in blender.

• Simulating Smartphones on PC with Unity

  - by Cengiz Frostclaw

  I want to make a game that depends on the phone orientation (changing shoot direction with tilt), however I need to test this on PC. So is there any tool I can use to simulate the orientation of the phone with mouse or keyboard of my PC? Something like joysticks on the screen. Thanks for any help! Edit : Thanks to @jhocking for his suggestion of Unity Remote. I, however still can accept a solution with using only PC, since I'm afraid of shortening my phone's battery life, for some reason.

• Cannot mount Android phone and sync with Banshee

  I can't get my LG Optimus One to sync with Banshee. I read somewhere that the root needs to have an empty file called '.is_audio_player'. I did that and it still doesn't mount.

• Program To Cascade/Tile Windows

  - by Richard

  I have perhaps ten or fifteen windows open. I'd like a program which automatically resizes all the windows and arranges them in columns and rows across the screen (a grid formation), automatically figuring out the largest size for the windows so that they still fit. This isn't an "Expose" type program - I want the windows to stay resized. I am using OpenBox to do my window management and am otherwise happy with it, I don't want to find a whole new window manager just to solve this problem. The program Tile is almost perfect, but it doesn't know how to lay the windows out in a grid formation. Any thoughts? Thanks!

• How to restore GRUB without re-installing the OS?

  - by Calixte

  A friend of mine has a Packard Bell laptop that came with Windows pre-installed. I installed Ubuntu on it and it works fine, but everytime she tried to boot Windows on it (fortunately rarely) it fails and the computer is unable to boot any OS anymore. Upon boot, the computer stops on a black screen with a GRUB Rescue prompt. Is there any way to restore GRUB without re-installing Ubuntu? (preferably an easy way as I cannot do it for her and she is not extremely computer literate) Also (but less important), is there a way to configure GRUB (or something else) so that Windows won't destroy it on every boot attempt?

• 12.04 64 bit: Keybord not responding for about 20 seconds at startup/beginning of session

  - by Danilo

  I am running Ubuntu 12.04 64bit. When I get at the login screen and try to type the password for my user, I cannot type anything for about 20 seconds. After that, the keyboard starts responding and everything works fine. Mouse is responding normally as well as all buttons of the login interface (time/calendar, session selection (Unity/Unity 2D), etc.). What could be the reason for this behavior? How can I solve this temporary freeze of the keyboard so that I can type my password immediately without having to wait each time? Thanks for your time. EDIT: I tried auto login, but the problem is still there: the Desktop loads but even there, if I try to type something in the dash or anywhere else, I must wait about 20 seconds before I can actually start typing. Can the issue be related to some keyboard modules that get loaded little bit "too late"?
