  • Problems with input and suspend(separately)

    - by VaultPrisoner
    I'm still very new at Ubuntu/any other linux OS, so this might be an easy fix for most. I installed Ubuntu 14.04 a few days ago, it's dual-booted with Windows 8.1 and I'm using a Toshiba laptop. Whenever I suspend/close my computer, and then open it again, the front LEDs will light up telling me that it's running, but the screen will not do anything. I can hear the fan spinning, but it's almost like the screen doesn't power on like it should. Also, another problem I'm having, is that ~60% of the time, my trackpad and keyboard do not work at all, this starts as soon as Ubuntu boots up. To fix it, I just turn it off and back on until it works. My USB mouse does work no matter what though. Both problems are only present in Ubuntu and not windows 8.1.

  • Ubuntu will not install on my Dell Inspiron 580

    - by AndrewC
    I'm trying to install ubuntu on my Inspiron 580 (Intel Core i3 4Gb Ram Intel HD Graphics) but am having no success installing from CD or Windows installer all result in a purple rapidly flashing screen with the Ubuntu with 5 dots below it splash which doesn't change. I have tried releases 12.04.1 LTS (CD and windows installer), 11.10 (CD after reading it was certified for the 580) and today 12.10 (CD) all produce the same install failure. My Dell 1704PT monitor is connected to the intel HD board using an HDMI to DVI adaptor though I have tried a VGA cable and still got the same flashing screen. Any help gratefully received as i want to get away from Windows 7 Home Premium.

  • Ubuntu 13.10 is terrible

    - by user137017
    I was satisfied with 13.04. But when I upgraded to 13.10, I've had a lot of issues and some things just no longer work. To name a few problems: Can't change the brightness My laptop makes more noise than before It freezes more frequently (the kind that doesn't respond to ctr + alt + f2) Sometimes it boots up and and can't play any media files When running a full screened virtual machine in Workstation, ubuntu catches mouse at the edges When I have a VM opened in Workstation and I try to open up another, the first one gets powered off Most irritatingly, when I have a virtual machine running in full screen, every now and then the vm screen goes black and I have to switch to the host and come back 13.10 has offered nothing to compensate for these problems. I would like to get some advice about what I can do. Should I stick with 13.10 and hope the bugs will be fixed? Would a clean reinstall of 13.10 help? Btw, I'm giving some thought to trying other distros.

  • Ubuntu 12.10 - launcher stays hidden

    - by Mieszko
    Just upgraded to 12.10 today. Everything seems fine for now, aprat from one thing: The launcher on the left side of the screen doesn't come up after moving the cursor to the left side of the screen. It IS there since it show the app start animation and I can have it on top all the time, but I'm really fond of it being hidden most of the time. I did check the sensitivity settings and even set it up to MAX (thus high) and it changes nothing. Please help ;) Cheers

  • Android layout issue - relative widths in percent using weight

    - by cdonner
    I am trying to assign relative widths to columns in a ListView that is in a TabHost, using layout_weight as suggested here: <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TableLayout android:id="@+id/triplist" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingTop="4px"> <TableRow> <ListView android:id="@+id/triplistview" android:layout_width="fill_parent" android:layout_height="wrap_content"/> </TableRow> <TableRow> <Button android:id="@+id/newtripbutton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Add Trip"/> </TableRow> [other tabs ...] My row definition has 4 columns that I would like to size as follows: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:weightSum="1.0" android:padding="4px"> <TextView android:id="@+id/rowtripdate" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content" android:inputType="date"/> <TextView android:id="@+id/rowodostart" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content"/> <TextView android:id="@+id/rowodoend" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content"/> <TextView android:id="@+id/rowcomment" android:layout_weight=".4" android:layout_width="0dip" android:layout_height="wrap_content"> Unfortunately, it seems to want to fit all the columns into the space that the button occupies, as opposed to the width of the screen. Or maybe there is another constraint that I do not understand. I'd appreciate your help.

  • How do you set tab view to scroll?

    - by DrogoNevets
    I have managed to set up a tabbed view for my app (woo!) and have the following xml for the UI <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="wrap_content"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Spinner android:id="@+id/areaSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <Spinner android:id="@+id/cragSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <Spinner android:id="@+id/routeSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <DatePicker android:id="@+id/dateClimbed" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <Spinner android:id="@+id/styleSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <Spinner android:id="@+id/detailsSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <TextView android:id="@+id/climbNotes" android:layout_width="fill_parent" android:layout_height="@dimen/three_row" /> </LinearLayout> yet am seemingly unable to scroll down to see the rest of the form (cuts off at one of the spinners, why is this? and how do i fix it?

  • UINavigationController as detail view of a UISplitViewController

    - by user309305
    Hi. I set up a navigation controller as detail view of a split view controller (NewFeedsNavigationController is inherited from UINavigationController). - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after app launch masterViewController = [[MasterViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController]; NewsFeedsNavigationController *newsFeedsNavigationController = [[NewsFeedsNavigationController alloc] initWithCategories]; splitViewController = [[UISplitViewController alloc] init]; masterViewController.splitViewController = splitViewController; splitViewController.viewControllers = [NSArray arrayWithObjects:masterNavigationController, newsFeedsNavigationController, nil]; splitViewController.delegate = newsFeedsNavigationController; // Add the split view controller's view to the window and display. [window addSubview:splitViewController.view]; [window makeKeyAndVisible]; return YES; } As a matter of fact the navigation controller works splendid in the portrait orientation but kind of freaks out in landscape orientation. when navigating back in the hierarchy (towards the root view) i always have to tap twice per view. on the first tap the visible view is poped from the stack and on the second tap the navigation bar turns. usually both of this happens at the same time. i have no idea what is going wrong.

  • How to add controls to a Tab Layout in Android?

    - by chobo2
    Hi I am following this tutorial http://developer.android.com/intl/de/guide/tutorials/views/hello-tabwidget.html and have completed it. Now I would actually like to add you know some controls to these tabs like textboxes(text edit). How do I do this? I go to my mail.xml using eclipse as my ide and go to layout view and I now get a NullPointerException so I can't even drag stuff onto the layout anymore. Thanks Edit This is what I have <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/textview1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a tab" /> <EditText android:text="" android:id="@+id/EditText01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:password="true"></EditText> </LinearLayout> <TextView android:id="@+id/textview2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is another tab" /> <TextView android:id="@+id/textview3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a third tab" /> </FrameLayout> </LinearLayout> </TabHost>

  • html textfield in WebView in an Android application is hidden by the soft keyboard

    - by user280503
    Hello, I have an Android application that is a TabHost with a WebView. I use it to load a specific html file that has a text field in its bottom part. When I touch the html textfield, the soft keyboard pops up, and hides the textfield, so that I cannot see what I have typed. Here is the layout: <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/main" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TabWidget android:focusableInTouchMode="false" android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="63dp" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/layout" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <WebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" /> </LinearLayout> </FrameLayout> </LinearLayout> </TabHost> I have tried to configure the AndroidManifest.xml file with android:windowSoftInputMode="adjustResize" with no success. I have also tried replacing the FrameLayout in my layout with ScollView, but that caused my webview to increase in size indefinitely when the application is running.. this may be due to some javascript I have running on the page. I have noticed that the android's web browser has a nifty behaviour - in a web page, after the soft keyboard pops up, the web page scrolls smoothly so that the focusable textfield is visible to the user. How can I have this kind of behavior in my applicaiton?

  • Tiff Analyzer

    - by Kevin
    I am writing a program to convert some data, mainly a bunch of Tiff images. Some of the Tiffs seems to have a minor problem with them. They show up fine in some viewers (Irfanview, client's old system) but not in others (Client's new system, Window's picture and fax viewer). I have manually looked at the binary data and all the tags seem ok. Can anyone recommend an app that can analyze it and tell me what, if anything, is wrong with it? Also, for clarity sake, I'm only converting the data about the images which is stored seperately in a database and copying the images, I'm not editting the images myself, so I'm pretty sure I'm not messing them up. UDPATE: For anyone interested, here are the tags from a good and bad file: BAD Tag Type Length Value 256 Image Width SHORT 1 1652 257 Image Length SHORT 1 704 258 Bits Per Sample SHORT 1 1 259 Compression SHORT 1 4 262 Photometric SHORT 1 0 266 Fill Order SHORT 1 1 273 Strip Offsets LONG 1 210 (d2 Hex) 274 Orientation SHORT 1 3 277 Samples Per Pixel SHORT 1 1 278 Rows Per Strip SHORT 1 450 279 Strip Byte Counts LONG 1 7264 (1c60 Hex) 282 X Resolution RATIONAL 1 <194 200 / 1 = 200.000 283 Y Resolution RATIONAL 1 <202 200 / 1 = 200.000 284 Planar Configuration SHORT 1 1 296 Resolution Unit SHORT 1 2 Good Tag Type Length Value 254 New Subfile Type LONG 1 0 (0 Hex) 256 Image Width SHORT 1 1193 257 Image Length SHORT 1 788 258 Bits Per Sample SHORT 1 1 259 Compression SHORT 1 4 262 Photometric SHORT 1 0 266 Fill Order SHORT 1 1 270 Image Description ASCII 45 256 273 Strip Offsets LONG 1 1118 (45e Hex) 274 Orientation SHORT 1 1 277 Samples Per Pixel SHORT 1 1 278 Rows Per Strip LONG 1 788 (314 Hex) 279 Strip Byte Counts LONG 1 496 (1f0 Hex) 280 Min Sample Value SHORT 1 0 281 Max Sample Value SHORT 1 1 282 X Resolution RATIONAL 1 <301 200 / 1 = 200.000 283 Y Resolution RATIONAL 1 <309 200 / 1 = 200.000 284 Planar Configuration SHORT 1 1 293 Group 4 Options LONG 1 0 (0 Hex) 296 Resolution Unit SHORT 1 2

  • Does Android XML Layout's 'include' Tag Really Work?

    - by Eric Burke
    I am unable to override attributes when using <include> in my Android layout files. When I searched for bugs, I found Declined Issue 2863: "include tag is broken (overriding layout params never works)" Since Romain indicates this works in the test suites and his examples, I must be doing something wrong. My project is organized like this: res/layout buttons.xml res/layout-land receipt.xml res/layout-port receipt.xml The buttons.xml contains something like this: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <Button .../> <Button .../> </LinearLayout> And the portrait and landscape receipt.xml files look something like: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> ... <!-- Overridden attributes never work. Nor do attributes like the red background, which is specified here. --> <include android:id="@+id/buttons_override" android:background="#ff0000" android:layout_width="fill_parent" layout="@layout/buttons"/> </LinearLayout> What am I missing?

  • Android crashes when calling ImageButton

    - by Joël
    I have a crash (Application Stopped Unexpectedly) problem with this main.xml is a "HelloWorld" type project (while testing and learning features I need for my app) : I isolated the ImageButton as an issue, but I can't isolate any of the parameters... <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ImageButton android:id="@+id/picture" android:layout_width="240dip" android:layout_height="180dip" android:layout_gravity="center_horizontal" android:src="@drawable/icon" android:adjustViewBounds="true" android:cropToPadding="true" android:clickable="true" android:scaleType="fitCenter" /> </LinearLayout> icon.png exists in my resources... I can see the preview in the Layout tab, even though the image is not centered on the button, but I read that it was normal. The code below works fine (as a regular Button). I can also do the same as an ImageView. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:id="@+id/picture" android:layout_width="240dip" android:layout_height="180dip" android:layout_gravity="center_horizontal" /> </LinearLayout> I use Eclipse and the AVD, and all my learning is done on 2.1 (SDK level 7). I can't test the app on an actual device yet as I don't have it yet. Thanks in advance !

  • iphone cannot rotate views in TabBar controller

    - by Luc
    Hello, I am working on an application that consists of a TabBar controller. Within on of its tab, I have a subclass of UITableViewController, within this list I have a Core-plot graph in the first cell and some other data in the 4 following cells. When I return YES in the shouldAutorotateToInterfaceOrientation method, I would expect the autoresizing of the list view to happen, but... nothing. When I add some log in the willRotateToInterfaceOrientation method, they are not displayed. Is there something I missed ? Thanks a lot, Luc // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations //return (interfaceOrientation == UIInterfaceOrientationPortrait); NSLog(@"Orientation"); return YES; } - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration]; NSLog(@"Rotating"); if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) { NSLog(@"view land:%@", self.view); } if (toInterfaceOrientation == UIInterfaceOrientationPortrait) { NSLog(@"view portrait:%@", self.view); } }

  • Automatically Sizing UIView after Adding to Window

    - by Kristopher Johnson
    I have an iPad app that switches between different views in its main window. The view-switching code looks like this: - (void)switchToViewController:(UIViewController*)viewController { if (currentViewController != viewController) { [currentViewController.view removeFromSuperview]; currentViewController = viewController; [window addSubview:viewController.view]; } } The problem is that when the new view (a UISplitView) appears in landscape orientation, it is not sized to fill the entire window. There is an empty black space on the right. If I rotate the device and then rotate back, the view sizes itself properly. If the device is in portrait orientation, everything works fine. The UISplitView also gets sized properly if it is the first view I show. The problem only occurs if I switch to it after another view has been shown, in landscape. So, is there some way to force iPhone OS to resize the view after it has been added to the window? I've tried calling sizeToFit, but it didn't work. I've also tried setting the view's bounds to the window's bounds, and I've tried setting the frame.

  • Problem after dismissing a modal view used in conjunction with a uisplitviewcontroller

    - by user336274
    I'm having a hard time understanding why the following is happening (and how to fix it). I've created an application using the split-view based application. I've added a UiBarButtonItem called showTheModal which calls this method found in RootViewController.m: - (IBAction)showTheModal:(id)sender { theModalController.modalPresentationStyle = UIModalPresentationFullScreen; theModalController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [self presentModalViewController:theModalController animated:YES]; if ([detailViewController popoverController] != nil) [[detailViewController popoverController] dismissPopoverAnimated:YES]; The BarButtonItem of course, is shown at the bottom of the Default Root Controller (left side of the of the split view in landscape) or at the bottom of the popup (if in landscape). The modal view is dismissed by a button placed in a toolbar. It calls the following: [self dismissModalViewControllerAnimated: YES]; The problem I'm having is if rotate the screen, while the modal is up. Here is what happens in different scenarios (start refers to the orientation when the showTheModal button is hit, end refers to the orientation when I hit the dismissModal button). 1)Start landscape, end landscape: Everything appears fine. willHideViewController and willShowViewController methods are not called in the RootViewController (as expected) 2) Start landscape, end portrait: UI appears fine. willHideViewController is run TWICE (WHY?) 3) Start portrait, end portrait: UI appears fine. willHideViewController is run once (as expected) 4) Start portrait, end landscape: The 'Root List' button remains in the detail view (right side of the split view. Neither willHideViewController and willShowViewController are invoked (WHY??) Any thoughts as to why #2 and #4 don't behave quite the expected way?

  • WPF - expander Collapsed event being triggered by child controls with validation

    - by Shaboboo
    I have an expander that contains an ItemsControl. The items in the itemsControl are templated, some have textboxes in them, others have checkboxes. Both have bindings that cause validation. The styling and validation is working as expected. The problem is when I first expand the expander and cause a change to either control, the expander collapses again, this is not what I want. If I repeat this a second time this does not happen. I'm not sure what is triggering this strange behaviour. I've tried setting the focus to the itemsControl when the expander expands with no luck. What is differnt the second time it's expanded? Could it be the validation? Any Ideas? XAML: <Expander Header="{Binding SubSectionName}" Padding="0" > <ItemsControl ItemsSource="{Binding ConfigSubSectionSettings}" ItemTemplateSelector="{StaticResource Settings_Selector}" /> </Expander> <!-- Templates selected by the ItemTemplateSelector --> <DataTemplate x:Key="subSection_Bool"> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="lbl" Text="{Binding SubSectionName}" > <CheckBox x:Name="chk" IsChecked="{Binding BoolValue, ValidatesOnDataErrors=True}" VerticalAlignment="Center" Margin="2" > </StackPanel > </DataTemplate> <DataTemplate x:Key="subSection_Text"> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="lbl" Text="{Binding SubSectionName}" /> <TextBox x:Name="txt" VerticalAlignment="Center" Text="{Binding StringValue, ValidatesOnDataErrors=True}" /> </StackPanel> </DataTemplate>

  • Insufferable word wrap in Visual Studio XAML editor - is there any relief for 2010?

    - by DanM
    Just curious if the XAML editor is any better at auto-formatting and wrapping attributes in Visual Studio 2010. Here's how the editor auto wraps attributes in VS 2008: <StackPanel Grid.Row="0" Grid.ColumnSpan="3"> <StackPanel Orientation="Horizontal"> <TextBlock VerticalAlignment="Center" FontWeight="Bold" Text="Current User:" /> <ComboBox x:Name="_usersComboBox" Margin="5,0,0,0" Width="200" ItemsSource="{Binding Users}" SelectedValuePath="Name" SelectedValue="System Administration"> <ComboBox.ItemTemplate> <DataTemplate> Here's how I'd like the editor to auto wrap attributes: <StackPanel Grid.Row="0" Grid.ColumnSpan="3"> <StackPanel Orientation="Horizontal"> <TextBlock VerticalAlignment="Center" FontWeight="Bold" Text="Current User:" /> <ComboBox x:Name="_usersComboBox" Margin="5,0,0,0" Width="200" ItemsSource="{Binding Users}" SelectedValuePath="Name" SelectedValue="System Administration"> <ComboBox.ItemTemplate> <DataTemplate> Does VS 2010 grant my wish?
