  • Just installed Ubuntu 12.04. When booting, all I get is a black screen with cursor

    - by user66378
    Installation appears to go fine. After rebooting, I get my motherboard loading screens, but when it comes time for Ubuntu to boot, I just get a black screen with a blinking white underscore in the top-left - same as I got when waiting for the install CD to load, except it lasts forever. The only keypress it seems to recognize is ctrl+alt+del, which reboots. Letters don't register, function keys w/ or w/o modifiers do nothing. I've installed Ubuntu 12.04 twice and got the same error. The first time, I installed it as the only OS, and had it take up the whole disk. The second time, I installed Windows 7 first, then Ubuntu by specifying custom partitions. After this install, it would boot straight to Windows without showing grub. I used EasyBCD to add the Ubuntu installation to grub, and this got grub to show, and let me select it, but it led back to the same error described up top. I've had Linux Mint 11 and 12 installed on this PC, but was unable to get previous versions of Ubuntu to install (always had errors while installing, not after). Hardware: Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 ASUS SABERTOOTH P67 (REV 3.0) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard EVGA 01G-P3-1371-TR GeForce GTX 460 (Fermi) CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Western Digital RE4 WD5003ABYX 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive

  • UIViewController takes up entire screen in Interface Builder

    - by Sheehan Alam
    I have a NIB with a UIView that contains some UILabels, UIButtons etc. and a UIViewController that is loading a detached NIB. I want the UIViewController to be positioned below my UIView, but whenever I add it in Interface Builder it takes up the whole screen, and my UIView becomes part of the UIViewController. How can I make sure UIViewController appears below the UIView?

  • Android: Determine when an app is being finalized vs destroyed for screen orientation change

    - by Matt
    Hi all, I am relatively new to the Android world and am having some difficultly understanding how the whole screen orientation cycle works. I understand that when the orientation changes from portrait to landscape or vice versa the activity is destroyed and then re-created. Thus all the code in the onCreate function will run again. So here's my situation: I have an app that I am working on where it logs into a website, retrieves data, and displays it to the user. While this is all done in background threads, the code that starts these threads is in the onCreate function. Now, the problem lies in that whenever the user changes the screen orientation, the app will log in, retrieve the data, and display it to the user again. What I would like to do is set a boolean that tells the app if it is logged in or not so it knows whether or not it must log in when the onCreate function is called. So long as the app is in memory the HttpClient will exist and contain the cookies from logging the user in but when the app is killed by the system those will go away. So I would assume that I need to do something like setting the logged in boolean to false when the app is killed but since onDestroy is called when the screen is rotated how is this possible? I also looked into the finalize function and isFinishing() but those seem to not be working. Shorter version: How can I distinguish between when an app is being killed from memory from when an activity is being rotated and different code for each event? Any help or a point in the right direction is greatly appreciated. Thank you!

  • iPad3 HD Black Screen in Portrait Orientation

    - by Jason Brooks
    I'm currently updating my game using XCode 4.3.1 and an iPad3. WHen iPAD HD mode is selected, I get a black screen when I change the scene from the AppDelegate. I'm using COCOS2d v1.0.1 My Game is portrait only mode, and I think I've tracked the problem down. If you create a new project with the default HelloWorld Layer, it works on the iPad3 and it's simulator in HD. However if you change the following code :- -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { ... #elif GAME_AUTOROTATION == kGameAutorotationUIViewController // // EAGLView will be rotated by the UIViewController // // Sample: Autorotate only in landscpe mode // // return YES for the supported orientations //return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) ); return ( UIInterfaceOrientationIsPortrait ( interfaceOrientation ) ); //return NO; ... } In RootViewController.m You see a black screen for the iPad3 real device and simulator. It works as expected on all devices, iPhone/iPod Touch, and iPad 1 and 2. If I change the statement back to return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) ); I get the Hello World rendered to the screen, but it is in landscape only on iPad3. Has anyone else encountered this and have any suggestions for a fix? The project is quite large to upgrade to the latest V1 Beta code.

  • wrap from last screen to first screen in android Launcher2

    - by poboy975
    hi, I'm learning java and android. and I've been looking at trying to wrap the last screen to the first screen in the android Launcher2. I've tried googleing, and searching here, but there really isnt much information about the launcher2 source...I've been modifying the workspace.java file, but there has been minimal effect. no wrap around so far...I have not been able to find a .xml file that also might control the hard stop when you reach the end of the screens. I'll give a small example of the code that i have been modifying. original code: public void scrollRight() { clearVacantCache(); if (mNextScreen == INVALID_SCREEN && mCurrentScreen < getChildCount() -1 && mScroller.isFinished()) { snapToScreen(mCurrentScreen + 1); } modified code: public void scrollRight() { clearVacantCache(); if (mNextScreen == INVALID_SCREEN && mCurrentScreen < getChildCount() -1 && mScroller.isFinished()) { snapToScreen(mCurrentScreen + 1); }if (mCurrentScreen == getChildCount() -1 && mScroller.isFinished()) { snapToScreen(0); I would appreciate any tips or pointers if anyone has an idea where i'm going wrong, or someplace i can search to get the answers. the code looks to me like it should work, but I'm probably missing something obvious.

  • Disabling assistive technologies during login

    - by Ivan
    I have a laptop with Ubuntu 10.04. My daughter was playing with the keyboard on the login screen, and it seems she activated some assistive technologies because now the screen is split vertically and the right side shows a magnified version of the left side. Plus, there's a screen keyboard. The way the screen is split makes it impossible for me to disable the assistive stuff from the toolbar at the bottom, since I can only see part of it. I don't know if it's a bug or what, because I'd guess I could see the entire bar on the right (magnified) side just by moving the mouse there, but I can't. I can't even type on the login screen, nor use the on-screen keyboard... Good thing I have auto-login activated, so I can still use the computer, but I can't switch users. So, does anyone know how to get the normal login screen back?

  • iPhone UIView element similar to the lock screen

    - by Travis
    Does anyone know if there is an open source project for an UIView element that acts in a similar way to the lock screen for the iPhone. I am working on an app that has some sensitive data, and I want to add another layer of comfort for users, to be able to setup a 4 digit pin number on the app. I've seen apps like LoseIt and Weightbot that have similar functionality. There isn't any element for this in the UI Library from what I've been able to find, and was hoping some kind soul might have open sourced something similar to this. Thanks in advance!!!

  • touchend event doesn't work on Android

    - by Protos
    Hi, I've just started looking at doing some basic mobile web development on the android and an writing a test script to investigate the touch events. I've run the following code in the android emulator, and the touchend event never gets fired. Can anyone tell me why ? I've tried in three versions of the emulator (1.6, 2.1 and 2.2) and all three behave in the same way. Thanks in advance for any help you can give me. Cheers, Colm EDIT - I've also tried this using the XUI framework and have the same problem so I'm guessing I have a fundamental misunderstanding of how this stuff works ......

  • Setting the origin to center of the screen instead of the top left screen?(iPhone)

    - by thyrgle
    Hi, I am working on an iPhone app and I am trying to make something that has to do with line-circle collision detection. I am using the slope of the line and checking if the coordinates of a circle suffice the equation y = mx + b. But, with the current origin (0,0) at the top left it is a pain to get the slope. Any way I can convert the coordinates so the origin is in the center of the screen?

  • Can Adobe AIR Desktop application take full screen snapshots (aka Print Screen button)

    - by tzador
    I would like to know if its possible to get full screen snapshots from an air application. What i am interested in, is functionality similar to PrintScreen button in windows, which takes snapshots of all screens, including third party application windows, not just window in which air app is running. If its not specific to air, and flash/flex API can provide such functionality, it also would be great. Thanx a lot in advance.

  • Prevent Changing the Screen Saver and Wallpaper in Windows 7

    - by Mysticgeek
    Sometimes you might not want users to have the ability to change Screen Savers and Wallpaper on Windows 7 workstations. Today we look at how to prevent them from changing either one or both. You might administer computers in your home or small office and find it annoying when users continuously change the wallpaper and Screen Savers to something obnoxious. A lot of times they might be inexperienced users and download these so-called “wonderful and free” Screen Saver/Wallpaper packages from shady sites that include loads of Spyware. Preventing users from changing them is another helpful tool to avoid wasteful time spent switching things back. Prevent Changing Screensavers & Wallpaper Using Group Policy Editor  Note: This method uses Group Policy which is not available in Home versions on Windows 7. Open the Start Menu and enter gpedit.msc into the Search box and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates \ Control Panel \ Personalization. Then in the right column double-click on Prevent changing desktop background. Now check the radio button next to Enabled, then click OK. Back on the Group Policy Screen, double-click on Prevent changing screen saver. In the next screen select the radio button next to Enable, click OK, then close out of Group Policy Editor. Now when a user goes into the Personalization section, the Desktop Background hyperlink is now grayed out and inactive. Notice the message One or more of the settings on this page has been disabled by the system administrator at the bottom of the section. If they click to change the Screen Saver, an error message will pop up letting them know the function is disabled. Prevent Changing Screensavers & Wallpaper Using a Registry Hack You can also make a couple Registry changes to prevent users from changing the Wallpaper & Screen Saver…which will work on Home versions of Windows 7. Before making any Registry changes make sure you back it up first. Open the Registry by typing regedit into the Search box in the Start menu and hit Enter. First we’ll start with the Wallpaper. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System and create a new String Value and name it Wallpaper. Then modify the Value data to point to the location of the Wallpaper you want it to always be. Where in this example it’s our main wallpaper on our local drive…then click OK. Now let’s make sure they can’t change the Screen Saver. In the same Registry location, we need to make a new DWORD (32-bit) Value. Give it the Value name of NoDispScrSavPage and the value data of “1” and click OK. Close out of the Registry and restart the machine or simply log off then back on again for the changes to take effect. Results For the Wallpapers, a user can still go in and see the selections, however if they try to change it to something else… It will just go back to the Personalization screen and no changes will be made, as we set the value to only be the background we specified. If the user tries to make a change to the Screen Saver, the hyperlink will be grayed out and inactive, and the message One or more of the settings on this page has been disabled by the system administrator will be displayed at the bottom of the section. Conclusion If you’re tired of users changing the Wallpaper and Screen Saver, and want another way to help avoid Malware, locking down these settings can help a lot. Again, before making any changes to the Registry, make sure to back it up. These settings should work in Vista and XP as well.

  • Automatically locking screen without shutting it off

    - by milkandtang
    Hey everyone— I have a home theater PC running Ubuntu 11.10, outputting over HDMI (for audio and video). I'm having an issue: I'd like the screen to lock automatically (when video is not playing, of course) but do not want the screen to turn off automatically, because that kills audio. I can manually lock the screen, of course, but it appears that if you set the "Turn off screen" setting to "never", the screen will never lock, no matter what the "lock screen" timeout is set to. Is there a way to do what I'm asking, or will I have to install xscreensaver?

  • HTG Explains: Why Screen Savers Are No Longer Necessary

    - by Chris Hoffman
    Screen savers are a left-over solution from a previous technology. In spite of their name, screen savers no longer “save” anything – all they do is waste electricity. Screen savers are not necessary on modern, flat-panel LCD displays. Having your computer automatically turn off its display is the new “screen saver” – it saves energy, reduces your electricity bill, and increases your battery life. Screen savers may look pretty, but they do it when no one is looking.

  • Full screen: launchbar + panel overlaps when showing a dialog box

    - by user85921
    I'm developing a program for 12.04 that will run on full-screen, so I would like to have full control of what appears on the screen. However, when I show another window (possibly a dialog/message box), the Uunity Panel and Launcher appears on the top and left side of the screen. I've experienced this behavior with other applications (Firefox, Gnubg) as well when in full-screen mode. I tried to play with the settings, now my dialog box is hidden from the the taskbar, set to float on it's parent, which is my full screen window. The problem still exists. Is there a way to prevent these panels from showing up, when the new window isn't shown in taskbar, or it's parent is a full-screen window? Or do I need to completely disable them?

  • Change Call Screen

    - by vyana
    I need to change or customize the call screen when initiating a call on Android. After searching on google I do not find any way to do it. There is no way to send DTMF tones during a call, the idea is to send a specific number to the call screen. So when a call is made is possible to see the number to dial during a call to the PBX. I tried to putting the number in the "status bar", but the notification hide after seconds and it is not practical. I appreciate any other suggestion. Thanks

  • Screen capture from windows service

    - by bezieur
    I've got DirectShow based screen capture software. Internally it calls CopyScreenToBitmap function to grab screen. Then the picture is compressed by ffdshow. It works fine as a desktop application, but as window service, on certain computers it does not work (black picture). I've set 'Allow service to interact with desktop' and run that service on current user account. Any ideas what could be wrong? I test it on windows XP, but it is expected to work on Vista and 7 as well. Yes it works as desktop application on all computers, but on some of them (on majority of them) it fails as a service.

  • convert.php does not run in a screen session

  • Screen overlay with Python, paint over an active window with background python script

    - by tvlife.admin
    Hi I'm writing a python script that runs in the background and takes screenshots of another application that is active. Then it analyses the screenshots and now it should overlay a certain image over the active app or the screen. I still need to be able to make mouse and keyboard inputs in the active app. So I need a way to overlay/paint on another window or on the screen, and still keep the other window the active window so that I can make inputs. I would prefer to do that with python in Mac OS, but if it isn't possible, other languages and even Windows (if really necessary) would also be ok. Can anybody help me? Thanks in advance!

  • Android - Adjust screen when keyboard pops up?

    - by Donal Rafferty
    I want to be able to adjust my UI screen on Android when the soft keyboard pops up. So at the minute I have something similiar to the first picture below where I have and EditText at the bottom of the screen and when a user taps the EditText I want the same as what happens in the second picture. That is that the EditText gets moved up and appears to "sit" on top of the soft keyboard, when the soft keyboard dissapears it should then return to its prior state. Can anyone let me know the best way to approach and implement this?
