  • Lenovo Ideapad Unstable Touchpad Cursor

    - by vicban3d
    I recently installed Ubuntu 14.04 on my Lenovo Yoga 2 Pro and there is a problem with the touchpad. Whenever I lift my finger from the touchpad or click, the cursor moves a little bit to a random direction which makes me miss the target I wanted to click. This is very annoying and I couldn't find a solution online. Can anyone tell me whether there is a solution to this problem and how would I fix it? Thanks in advance.

  • Set the caret/cursor position to the end of the string value WPF textbox

    - by Zamboni
    I am try to set the caret/cursor position to the end of the string value in my WPF textbox when I open my window for the first time. I use the FocusManager to set the focus on my textbox when my window opens. Nothing seems to work. Any ideas? Note, I am using the MVVM pattern, and I included only a portion of the XAML from my code. <Window FocusManager.FocusedElement="{Binding ElementName=NumberOfDigits}" Height="400" Width="800"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <TextBox Grid.Column="0" Grid.Row="0" x:Name="NumberOfDigits" IsReadOnly="{Binding Path=IsRunning, Mode=TwoWay}" VerticalContentAlignment="Center" Text="{Binding Path=Digits, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/> <Button Grid.Column="0" Grid.Row="1" Margin="10,0,10,0" IsDefault="True" Content="Start" Command="{Binding StartCommand}"/> </Grid> </Window>

  • Chrome extension custom cursor

    - by the_nakos
    Hi, I building an Google Chrome extension that place some IMG tag in sites. This img tag on :hover must show a custom cursor. The extension uses jQuery as its injected core script. I tried the following methods: 1. var cursor = 'url('+chrome.extension.getURL('icons/cursor.cur')+')'; $('#myImgId').css({ 'position': 'absolute', 'top':'5px', 'left':'5px', 'cursor':cursor }); This is the best working. On smaller sites its shows the cursor. On slower loading sites it does not. But on little sites it fails sometimes. 2. var cursor = 'url('+chrome.extension.getURL('icons/cursor.cur')+')'; $('<style>#myImgId{cursor:'+cursor+'}</style>').appendTo('head'); This did nothing at all. 3. In manifest.json I injected the css. "content_scripts": [ { "matches": ["http://*/*"], "css": ["css/style.css"], "js": ["j/c.js", "j/s.js"] } The css file just had the cursor:url(icons/cursor.cur) as I don't have idea, how to get real url in a css file. This isn't working at all. I think it must work like this, I didn't find reference for this on code.google though.

  • Black screen and blinking cursor for a while during Startup

    - by Soumyadip Mukherjee
    I've installed the Ubuntu 12.04.1 "rock solid" release. Everything works fine apart from the fact that during start-up the usual purple screen and Ubuntu logo doesn't appear. Only a black screen and blinking cursor is visible. Then after a while, for a fraction of a second, the Ubuntu logo and purple screen comes and disappears to the login page. I tried Plymouth but it didn't help in solving the problem. It did end up changing the logo to a more artistic one. Can any one please help? Ubuntu is installed on my ASUS 1225c netbook.

  • Bastion unexpectedly exits when I move my cursor

    - by user69358
    I downloaded the Humble Indie Bundle V, mostly because my friend told me about how great Bastion was. When I first installed it, I was getting the seemingly common "black screen" error that most people got (fixed that half with this http://ubuntuforums.org/showthread.php?p=11992661). But I also have an error where every time I move my cursor, in any direction, any amount, the game closes instantly. I can use the keyboard no problem, but without fail, every time I move my mouse, it crashes. Does anyone know what might be causing this? Has anyone encountered anything like this before? I am worried it may be a hardware issue, but hoping someone might be able to help me out. I'm running Ubuntu 12.04 on a Dell Studio 1558. Graphics card is the stock Intel graphics card, running on 4 GB of RAM.

  • Cursor seems to freeze in the first attempt to type - Unity 3D, 12.04

    - by Denis
    It happens in the first attempt of typing, no matter is after the startup, or 5 minutes later, or then after. The cursor (or maybe it's the system) seems to freeze, no matter the application I use, taking up 4 to 5 sec to appear what is typed. Subsequently, everything is normal, using another applications. @Anwar Shah suggested it could be a daemon waiting to run before the lauching of the first application. Turning off Zeitgest didn't help. It occurs only with Unity-3d. Tested with Unity-2d, everything is fine. Tried to change some Compiz settings, nothing worked, although not tested with every single parameter. Also I deactivated Ati proprietary driver, no effect. My system: AMD E350 1.6Gh, 2G-Ram, ATI graphics - Ubuntu 12.04, 64bits. Is that what I should expect, or can be fixed or improved? Thanks.

  • Booting Ubuntu shows only cursor, no desktop features

    - by jlkkljh
    I'm trying to install Ubuntu and have been trying since 2010 on my Win XP (2006-2008 I don't know which year's version exactly). I'm trying to get rid of XP and every time I install Ubuntu it doesn't work. I've tried all the options on the install list from Wubi and from inside the installer. I've tried a lot of different stuff and all it will load is a mouse cursor and a black screen. Please do help out with suggestions/advice. Thanks in advance.

  • Unity stuck in 2D mode, Nvidia Quadro graphics "unknown", Nvidia-Current active but not in use

    - by Jordan Lund
    I've seen this problem reported under several questions, but I haven't been able to resolve any of it so I thought I'd bring it all in under one umbrella. I started a new job and was given a Dell Precision M6400 laptop with Nvidia Quadro FX 2700M graphics card. It had a previous version of Ubuntu on it, but nobody had any passwords for it so I wiped the drive and did a fresh install of 11.10 from scratch. I didn't do any updates during installation, preferring to do them after boot. Updates ran fine and the system works... except Unity is in 2D mode. System Settings - Additional Drivers shows that Nvidia-Current is active but not in use. System Settings - System Info shows Graphics Driver Unknown, Experience Standard Nvidia X Server Settings is installed and working, re-writing the xorg.conf did nothing. /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: Quadro FX 2700M/PCI/SSE2 OpenGL version string: 3.3.0 NVIDIA 285.05.09 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes One suggestion was to do a sudo apt-get --purge remove nvidia* and that resulted in a scrambled screen on boot and a non-bootable installation. Pressing the Delete key on boot allowed me to access the recovery console and do a sudo apt-get install nvidia-current, which brought me back to a working, bootable system. Another suggestion was to edit /etc/default/grub and change the line reading "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to read "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=192MB" thus allocating more video RAM. I did that, followed by a sudo update-grub and a re-boot. No change. Created a brand new standard user and logged on with that account, no change.

  • How can I make the text cursor in X Windows easier to see?

    - by skyblue
    The text cursor in X Windows is too thin for me to see easily. It would be great if I could make the text cursor wider so that it was more visible. I know how to change the size of the mouse cursor in X by going to System Preferences Appearance and customizing the Pointer so that it is larger. But I have not been able to find any setting that allows me to alter the appearance of the text cursor. So how can I make the text cursor easier to see?

  • Change default mouse cursor on OSX Mavericks

    - by Ziarno
    Is there any way to change the default mouse cursor on OSX Mavericks? More precisely, I'd like to make it look like in windows, and even more precisely I want to move the 'point' where the mouse cursor actually 'clicks' - on windows it's on the very end of the arrow, even outside of it, and on mac it's a little inside the arrow. I've done some research, and all the websites either tell me to get Mighty Mouse, which doesn't work on my system, and other's tell me how to change the size of my cursor.

  • Cursor movement history in Vim

    - by Vi
    How can I restore cursor position in Vim as it was before scrolling, selecting or PgUp/PgDn? I'm tired of searching where I was before I scrolled up to look something at the top. Are there something like "Prev cursor position" and "Next cursor position" commands (like 'u' and 'R' for regular undo/redo)?

  • Start position for a reused t- sql cursor?

    - by Span
    I'm working on a stored procedure that uses a cursor on a temporary table (I have read a bit about why cursors are undesirable, but in this situation I believe I still need to use one). In my procedure I need to step through the rows of the table twice. Having declared the cursor, already stepped through the temporary table once and closed the cursor, would the position of the cursor remain at the end of the table when re-opened or does it reposition itself to the initial starting position (ie: before the first row)? Alternatively, to reposition the cursor must I do a 'FETCH FIRST' before stepping through again? Am I right to assume the 'cost' of doing this repositioning and reusing the cursor would be less than deallocating and reallocating the cursor?

  • How can I lock the cursor to the inside of a window on Mac OS X?

    - by ZorbaTHut
    I'm trying to put together a game for Mac OS X which involves a lot of fast action and flinging around of the mouse cursor. If the user wants to play in windowed mode, I'd quite like to lock the cursor to the inside of the window to avoid accidentally changing programs in the heat of battle (obviously this will cancel itself if the user changes programs or hits escape for the pause menu.) On Windows, this can be accomplished easily with ClipCursor(). I can't find an equivalent on Mac OS X. Is there one?

  • Flash video hiding the cursor on Mac OS X

    - by Tibor
    I found a Core Graphics function, CGCursorIsVisible, that one can use to determine whether the mouse cursor is shown on screen. I have a small app that uses a timer to call that function a few times a second to see if the cursor is shown or hidden (as I found no way to get my app notified when the mouse cursor shown/hidden status changes). The above works correctly except… when the Flash browser plugin plays a video: the mouse cursor gets hidden after a few seconds of mouse inactivity but CGCursorIsVisible() still keeps telling me that the cursor is indeed shown as if nothing happened. What I need is to be able to tell, at any given moment, whether the mouse cursor is shown to the end user on any screen. Is there any way to do that even in the case of playing a video using the Flash plugin?

  • WPF Show wait cursor before application fully loads

    - by e28Makaveli
    I want to show the wait cursor before my WPF application, composed using CAL, fully loads. In the constructor of the main window, I have the following code: public MainWindow([Dependency] IUnityContainer container) { InitializeComponent(); Cursor = System.Windows.Input.Cursors.Wait; Mouse.OverrideCursor = System.Windows.Input.Cursors.Wait; ForceCursor = true; //this.Cursor = System.Windows.Input.Cursors.AppStarting; // event subscriptions PresenterBase.EventAggregate.GetEvent<ModulesLoadedEvent>().Subscribe(OnModulesLoaded); } After all modules have been loaded, the following handler is invoked: private void OnModulesLoaded(EventArgs e) { allModulesLoaded = true; Mouse.OverrideCursor = null; Cursor = System.Windows.Input.Cursors.Arrow; } Problem is, I do not see this wait cursor. What I am missing here? FWIW, I got a hint from this post http://stackoverflow.com/questions/2078766/showing-the-wait-cursor TIA.

  • How to: Show wait cursor in managed and native code

    - by TechTwaddle
    Someone on the MSDN forum asked about how to show a wait cursor, like when your application is loading or performing some (background) task. It’s pretty simple to show the wait cursor in both managed and native code, and in this post we will see just how. Managed Code (C#) Set Cursor.Current to Cursors.WaitCursor, and call Cursor.Show(). And to come back to normal cursor, set Cursor.Current to Cursors.Default and call Show() again. Below is a button handler for a sample app that I made, (watch the video below) private void button1_Click(object sender, EventArgs e) {     lblProgress.Text = "Downloading ether...";     lblProgress.Update();     Cursor.Current = Cursors.WaitCursor;     Cursor.Show();     //do some processing     for (int i = 0; i < 50; i++)     {         progressBar1.Value = 2 * (i + 1);         Thread.Sleep(100);     }     Cursor.Current = Cursors.Default;     Cursor.Show();     lblProgress.Text = "Download complete.";     lblProgress.Update(); }   Native Code In native code, call SetCursor(LoadCursor(NULL, IDC_WAIT)); to show the wait cursor; and SetCursor(LoadCursor(NULL, IDC_ARROW)); to come back to normal. The same button handler for native version of the app is below, case IDC_BUTTON_DOWNLOAD:     {         HWND temp;         temp = GetDlgItem(hDlg, IDC_STATIC_PROGRESS);         SetWindowText(temp, L"Downloading ether...");         UpdateWindow(temp);         SetCursor(LoadCursor(NULL, IDC_WAIT));         temp = GetDlgItem(hDlg, IDC_PROGRESSBAR);         for (int i=0; i<50; i++)         {             SendMessage(temp, PBM_SETPOS, (i+1)*2, 0);             Sleep(100);         }         SetCursor(LoadCursor(NULL, IDC_ARROW));         temp = GetDlgItem(hDlg, IDC_STATIC_PROGRESS);         SetWindowText(temp, L"Download Complete.");         UpdateWindow(temp);     }     break; Here is a video of the sample app running. First the managed version is deployed and the native version next,

  • StaleDataException: access closed cursor

    - by Aurora
    In my application, after enough clicking around, I get this error: 06-08 19:47:59.967: ERROR/AndroidRuntime(2429): java.lang.RuntimeException: Unable to pause activity {com.MYAPP.app/com.MYAPP.app.MainActivity}: android.database.StaleDataException: Access closed cursor What I have is a Tab Activity (my MainActivity), which has a ListActivity as the contents for each tab. Inside the onCreate for each ListActivity I get a cursor that represents the data to be displayed in that list. The onListItemClick for each list also creates another activity, so clicking on an item in the list will show more information about that item in a new screen. It's inconsistent, but after enough clicking into these new activities, or going back to the ListView from a new activity, the program crashes. In searching around for a solution to my problem, I did stumble upon registerDataSetObserver, but it doesn't seem to be the whole answer. I am also having trouble finding documentation on it, so I'm not sure I fully understand it. I have a custom ListAdapter that both my ListViews use and have called registerDataSetObservers on the cursors there. I have attached the relevant code from one of my ListActivities and from my custom ListAdapter class. The ListActivity. I have two of these, almost identical, except they both have different cursors created from different database queries: import com.MYAPP.app.listmanager.DeviceListAdapter; public class AllSensorsActivity extends ListActivity{ private DeviceListAdapter AllList; private DbManager db; protected Cursor AllCur; protected Cursor AllSensors; private static final String TAG = "AllSensorsActivity"; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); Log.e(TAG, "Calling All onCreate"); db = new DbManager(this); db.open(); AllCur = db.fetchAllDevices(); startManagingCursor(AllCur); AllSensors = db.fetchAllSensors(); startManagingCursor(AllSensors); AllList = new DeviceListAdapter(this, AllCur, AllSensors); setListAdapter(AllList); } @Override protected void onListItemClick(ListView l, View v, int position, long id){ String device_name = (String) ((DeviceListAdapter)getListAdapter()).getItem(position); String sensor_string = ((DeviceListAdapter)getListAdapter()).getSensors(id); Intent i = new Intent(this, SensorActivity.class); Bundle bundle = new Bundle(); bundle.putString("NAME", device_name); i.putExtras(bundle); bundle.putString("SENSORS", sensor_string); i.putExtras(bundle); this.startActivity(i); } The custom ListAdapter: public class DeviceListAdapter extends BaseAdapter { private static final String TAG = "DeviceListAdapter"; private Context mContext; private Cursor mSensors; private Cursor mDevices; protected MyDataSetObserver sensors_observer; protected MyDataSetObserver devices_observer; public DeviceListAdapter(Context context, Cursor devices, Cursor sensors){ mContext = context; mDevices = devices; mSensors = sensors; sensors_observer = new MyDataSetObserver(); mSensors.registerDataSetObserver(sensors_observer); devices_observer = new MyDataSetObserver(); mDevices.registerDataSetObserver(devices_observer); } // ... more functions and stuff that are not relevant go down here... } private class MyDataSetObserver extends DataSetObserver { public void onChanged(){ Log.e(TAG, "CHANGED CURSOR!"); } public void onInvalidated(){ Log.e(TAG, "INVALIDATED CURSOR!"); } } Should I just have MyDataSetObserver catch the exception and move on? I'd like a more robust solution than that if possible. Or is there some other way I could rearrange my program so that the staleDataException doesn't occur (as often)? I believe that it is happening because I am launching the new activity in my onListItemClick.

  • Limiting the speed of the mouse cursor

    - by idlewire
    I am working on a simple game where you can drag objects around with the mouse cursor. As I drag the object around quickly, I notice there is some juddering, which seems to be due to the fact that I can move the mouse cursor faster than the game's update/draw. So, although I maintain the offset from where the player initially clicked on the object, the mouse's relative position to the object shifts around slightly before settling as I move the object very quickly. The only way I have found to get smooth, exact 1:1 movement is if I turn both IsFixedTimeStep and SynchronizeWithVerticalRetrace to false. However, I'd rather not have to do that. I have also tried making a custom mouse cursor, hiding the real mouse, taking the real mouse delta and clamping it to a maximum speed. Here is the problem: In windowed mode, the "real" mouse cursor moves off the window while the custom mouse cursor (since it's movement is being scaled) is still somewhere inside the game window. This becomes bizarre and is obviously not desired, as clicking at this point means clicking on things outside the game window. Is there any way to accomplish this in windowed mode? In fullscreen mode, the "real" mouse cursor is bounded to the edges of the screen. So I get to a point where there is no more mouse delta, yet my custom cursor is still somewhere in the middle of the screen and hence can't move further in that direction. If I wanted to clamp it to the edge of the screen when the real cursor is at the edge, then I would get an abrupt jump to the edge of the screen, which isn't desired either Any help would be appreciated. I'd like to be able to limit the speed of the mouse, but also would appreciate help with the first issue (the non-smooth relative offset between mouse cursor movement and object movement).
