• Touchpad & TrackPoint (ThinkPad L520) suddenly unresponsive

  - by yesyoar

  My mother has a problem with her ThinkPad L520 notebook (Ubuntu 11.10, Unity). She boots the device, everything works fine at first. But then, out of nowhere, her touchpad + trackpoint stop working. She can't click or drag the mouse. If she connects an external mouse, she can move the pointer and click (but the internal touchpad or trackpoint still don't work). She already updated everything through the update manager, but still no success...like I said, sometimes it works, sometimes it doesn't. There are no 'special' mouse drivers installed. What can I do to fix this? Thank you for your help! :)

• C++ unmanaged inside winform

  - by Gosso

  First: I am using C# and C++ on windows 7. I have created a basic rendering engine in c++ with directx 10. It works good as a stand alone application. But, when I sending the Form.Handle of a WinForm I want to render inside to the engine it crashes during D3D10CreateDeviceAndSwapChain with the following error: HRESULT: 0x887a0001 (2289696769) Name: DXGI_ERROR_INVALID_CALL I get the handle from the winform during loading of the form. unsafe { void *ptr=m_view.Handle.ToPointer(); uint v = (uint)ptr; lhandle = v.ToString(); };

• T-SQL Tuesday #014:I Hereby Resolve

  - by AllenMWhite

  It's another T-SQL Tuesday! Like many others, I really don't make New Year's Resolutions. They're too easy to forget about and it's too easy to "justify" why it just wasn't practical (and sometimes it's true.) That said, there are some things I'm working on changing for this year. Last year was the first full year for my new business venture, and it has been successful so far. I'm confident it's going to continue on this path, and we'll be doing even better this time next year. With that success...(read more)

• How to pre-configure (configure defaults for new users) KDE?

  - by luxifer

  I'm trying to figure out how to configure KDE for new users. That is: setting up KDE and make these settings default for every user upon her first login. I know that there's /etc/skel but it's not working nicely because KDE writes user- and machine-specific stuff in its users configuration files and I want this to work for every user on every machine. Also modifying stuff in /usr/share seems wrong to me as well as stuff there could get overwritten by an update or - even worse - modifications there could make auto upgrade fail. So, is there a standard way of doing this? Thanks

• Sun Broadband Wireless and Ubuntu

  - by Verge Riviero

  Good day! I recently installed 12.04. I am having a hard time connecting to the Internet using my Sun Broadband Wireless. I installed the 64-bit version. I am from the Philippines. When I plug in my USB stick, it does not show up on the Network Manager/ no new connection can be detected. I try to edit it using Edit Connections but still to no avail. I have tried doing these steps from kenji08, kartonista, and from review-ninja (for this one, I can't seem to get pass the first step.) I hope those information can help.

• Wifi connection problems

  - by user12511

  I have Ubuntu 10.10 installed on a HP Pavilion DV2750ea. The wifi card is an Intel 4965AGN. When I first started using Ubuntu on this laptop it connected wirelessly to the network. Then it suddenly stopped. The Wifi card power light is off and all information says the card is disabled. When the laptop is powered on the wifi power light turns on and stays on until Ubuntu finishes loading. I have replaced the wifi card and the wifi switch module with no change. Please can you help.

• How to install libdvdcss?

  - by skwd

  I'm relatively new to Ubuntu and I'm trying to figure out how to play DVDs. I've read through a lot of forums, and got to the one asking how to read encrypted DVDs. I was able to do the first step and installed libdvdread4, but when I got to the second step of installing libdvdcss, I got what amounted to error messages. This is the command I ran: sudo /usr/share/doc/libdvdread4/install-css.sh Is there something important that I should know? As in, probably something basic that I don't know because I'm new...?

• Is the Apple iPad for you now or should you wait until the iPhone 4 is released?

  The iPad came to the market last Saturday and as always with the Apple marketing came the big lines and small tents that never seen a camp site but the Apple stores. There are the people that want one right away and want to be the first person to own the new shiny device from Apple and there are the people that are willing to wait a month for the device with 3G instead of just WiFi only. The iPad is an interesting concept, a bigger iTouch that can be used as a replacement for your Netbook, Kindle,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Which is a better design pattern for a database wrapper: Save as you go or Save when your done?

  - by izuriel

  I know this is probably a bad way to ask this question. I was unable to find another question that addressed this. The full question is this: We're producing a wrapper for a database and have two different viewpoints on managing data with the wrapper. The first is that all changes made to a data object in code must be persisted in the database by calling a "save" method to actually save the changes. The other side is that these changes should be save as they are made, so if I change a property it's saved, I change another it's save as well. What are the pros/cons of either choice and which is the "proper" way to manage the data?

• (Phaser) Preload Future States in Create?

  - by Brian

  I'm a first time user of Phaser, been trying to make a simple point and click type game. I'm trying to keep things very modular, so I'm defining a list of levels (states) in a JSON, and then every level has its own JSON containing the objects within that level. However, I'm encountering an issue in that, when changing states, I get a black flash while the assets for the next state load (this happens whether I iterate through the JSON list or define everything manually). From what I've read, all sprites should be loaded in the preload stage, however, by doing this I'm causing that tiny but noticeable black pause. I know one way would be to simply load every asset at the start of the game, but that seems incredibly inefficient (wouldn't that fill up the memory immensely?). I would rather load a state's assets from the "parent" state. However, in my quick test (which maybe I did wrong) it seems that game.load doesn't work properly if done within the create stage? What is the best approach to doing this?

• Virtualbox Kernel driver not installed

  - by Cyndi

  I tried to use my Virtual Box and this is the error I received - (I just updated to the new Ubuntu also) and I am VERY new at this Linux OS :) Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

• Can't right click, copy or move files to Desktop???

  - by user1698774

  I am on Ubuntu 12.04 running gnome shell 3. Everything worked fine until I updated just a few hours ago using the update package. First my default shortcuts stopped working, fixed it by creating custom ones. Now while on the desktop I can't right-click, move files to it or see the files that were there previously. However, in terminal I can navigate fine to Desktop and my files are there, except not visually on the desktop. Permissions are all set correctly. Please help. Thank you.

• MVC Coding Style Best practices

  - by user1378680

  I'm trying to learn how to code in MVC ... Normally what i do most times is that I write all the codes first, then break out the functions.. Have the functions into a seperate file and include it at the top of the page when I need it. 1) This method seem to work for me, although that means i require more time to make out the functions. Is this normal for learners.? 2) When I'm doing MVC : Model - contains all the functions and it's included in the view View - This has to do with the display of the whole app What is the use of Controller? Thanks for you time and patience. I most appreciate it. My language prefrence is PHP with MySQL

• Wrong/corrupted icon in dash

  - by Swarnendu Biswas

  I am facing a problem with the dash not showing proper/actual icons for certain applications such as Google Chrome and Mozilla Daily Mail. Instead of getting the standard icons for these applications, I get to see a default icon for all the applications. I have added a snapshot to show the problem. The icons that are shown in the launcher once launched or in the /usr/share/applications directory are proper. I have tried rebuilding the icon cache, but that did not help. I have also tried switching to other icons themes. This issue does not appear with Gnome Shell or KDE. I have also tried deleting ~/.local/share/applications/menu-xdg, there was none in the first place. I am using Ubuntu 12.10. Any suggestions would be appreciated.

• Ubuntu13.10 64 bit installed alongside windows 7 32bit doesn't boot

  - by alone

  I have installed Ubuntu 64-bit alongside windows 7 32-bit. (Windows installed first.) The installation was successful, but when I restart it just goes directly to windows 7 without any sign of existence of Ubuntu. I'm a beginner who just wanted to get familiar with Ubuntu, but now I'm disappointed with it. Someone told me the not booting problem is related to EFI, but now I'm scared to play with this boot stuff because my information might be totally lost. How can I fix this boot problem and get to Ubuntu?

• 12.04 install now just blank screen

  I have attempted to install a new copy of 12.04 using usb stick instead of using download manager. Everything went fine while using usb stick until I restarted after installation was complete. Then, I got the screen with cursor and 4 lines of script with the first line saying "could not write to bytes: broken pipes". I have used several versions of Ubuntu from 6.04, but this one seems broken. I have tried nouveau.blacklist and many other suggestions to no luck. I am using hp pavilion m7790y dual core processor system, with nvidia 7600gt video card, 4gb ram and two hard drives with Vista on one and fresh install of Ubuntu 12.04 on other. I'm still looking for help to solve this problem. Thanks in advance.

• Migrating RISC to x86 - endianess 'issue'

  - by llaszews

  Endianess always comes up when migrating applications and databases from RISC to x86. The issue is often time overblown as if you are running on a relational database the database vendor will provide tools or automated methods to convert the data properly. Oracle RMAN is often the first choice. Oracle imp/exp, data pump, and GoldenGate can also be used. Migrating to Linux on Dell A bigger issue would be applications that access OS files. These OS files will need to be converted from big endian (RISC) to little endian (CISC) and then the application may be impacted because of the endianess differences.
