• HTC Diamond Touch sync problem

  - by Anders

  I have a HTC Diamond Touch with all my contacts etc. on it. Did however not use it for 6mo while being abroad. When I start the phone now I realize that the touch screen has stopped working. I have tried restarting, soft resetting, shutting it off etc but the touch just wont follow commands. However, I can manage the phone by buttons so it's not frozen. Hence I can get into the phone and watch contacts but not use it to call etc. The problem is, how do I get my 300 contacts out of the thing!? When I'm plugging in the phone, it lets me choose between "Sync with Outlook" and "Use as storage device". It automatically selects "Use as storage device". Now, I cannot choose to sync it with the buttons. I can not change this option afterwards either. In short, I have a phone with all of my contact data and am completely unable to get that out of it. Any tips/help/suggestions? If possible, preferably one that does not including sending the phone to a hardware workshop for three weeks in order to get it fixed:)

• Intercepting touch events on activity and button on Android

  - by hgpc

  I have an Android activity with an ImageButton. I would like to execute some logic when the button is clicked and show a different image for the pressed state, but also receive the touch event on the activity. By default only the button receives the touch event. If I set the clickable attribute of the button to false then only the activity receives the touch event. What's the best way to receive the touch event in both the activity and the button?

• How to cancel a touch sequence

  - by Alex

  I have an UIImage view that responds to touch events. I want to cancel the touch sequence if the touch goes outside of certain bounds. How can I do that? I know that I can inspect the coordinates of the touch object, what I don't know is how to cancel the sequence. I don't see any event in the API that allows for that.

• Problems with CGPoint in touches event

  - by Jason

  I'm having some problems with storing variables from my touch events. The warning I get when I run this is that coord and icoord are unused, but I used them in the viewDidLoad implementation, is there a reason why this does not work? Any suggestions? -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint icoord = [touch locationInView:touch.view]; } -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint coord = [touch locationInView:touch.view]; } - (void)viewDidLoad { if (coord.x > icoord.x) { player.center = CGPointMake(player.center.x + 5, player.center.y); } } Thanks.

• Terminal proxy or screen without terminal emulation

  - by ZyX

  How can I make terminal applications immune to terminal emulator close, but still able to use all virtual terminal features? I see this must be something like screen, but without VT100 terminal emulation, something which will just apply whatever application does with "terminal proxy"'s terminal (like outputting something to stdout/stderr or using stty to set terminal options) to the terminal this proxy runs in. // I know about screen and altscreen on, but it makes either this (screen with TERM=screen): or this (screen with TERM=rxvt-unicode): while I want this (rxvt-unicode without screen): I have figured out that everything looks fine if I compile rxvt-unicode with USE=-xterm-color (in fact vim looks like on the second picture even without screen if I add this USE flag) and set TERM=screen-256color, but I do not like this workaround because it actually changes colors and I can't be sure that it will always change them only this way:

• GNU screen, how to get current sessionname programmably

  - by Jimm Chen

  [ This can be considered step 2 of my previous question Is it possible to change GNU screen session name after created? ] Actually, I'd like to write a script that can display current screen session name and change current session name. For example: sren armcross It will change the session name to armcross (ARM gcc cross compiler) and output something like: screen session name changed from '25278.pts-15.linux-ic37' to 'armcross' So, the key question now is how to get current session name. Not only for display the old session name, but according to Is it possible to change GNU screen session name after created? , I have to know it(pass to -d -r) before I can change it to something else. Can we use $STY for current session name? No. $STY will not change after you have changed the session name to a user-defined one. However, for command screen -d -r <oldsessname> -X sessionname armcross should be the user-defined name(if ever defined) instead of $STY, otherwise, screen spouts error "No screen session found." Maybe, there is a verbose way, use screen -list to list all sessions(user-defined name listed), then, match the pid part from $STY against those listed sessions and we will find current session's user-defined name. It should not be so verbose for such a straightforward question. Don't you think so? The -d -D and -r -R options seems to expose too much implementation detail to screen's user. It seems, to rename a session, you have to detach it, then do the rename, then reattach it. Right? My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06 Thank you.

• Isometric screen to 3D world coordinates efficiently

  - by Justin

  Been having a difficult time transforming 2D screen coordinates to 3D isometric space. This is the situation where I am working in 3D but I have an orthographic camera. Then my camera is positioned at (100, 200, 100), Where the xz plane is flat and y is up and down. I've been able to get a sort of working solution, but I feel like there must be a better way. Here's what I'm doing: With my camera at (0, 1, 0) I can translate my screen coordinates directly to 3D coordinates by doing: mouse2D.z = (( event.clientX / window.innerWidth ) * 2 - 1) * -(window.innerWidth /2); mouse2D.x = (( event.clientY / window.innerHeight) * 2 + 1) * -(window.innerHeight); mouse2D.y = 0; Everything okay so far. Now when I change my camera back to (100, 200, 100) my 3D space has been rotated 45 degrees around the y axis and then rotated about 54 degrees around a vector Q that runs along the xz plane at a 45 degree angle between the positive z axis and the negative x axis. So what I do to find the point is first rotate my point by 45 degrees using a matrix around the y axis. Now I'm close. So then I rotate my point around the vector Q. But my point is closer to the origin than it should be, since the Y value is not 0 anymore. What I want is that after the rotation my Y value is 0. So now I exchange my X and Z coordinates of my rotated vector with the X and Z coordinates of my non-rotated vector. So basically I have my old vector but it's y value is at an appropriate rotated amount. Now I use another matrix to rotate my point around the vector Q in the opposite direction, and I end up with the point where I clicked. Is there a better way? I feel like I must be missing something. Also my method isn't completely accurate. I feel like it's within 5-10 coordinates of where I click, maybe because of rounding from many calculations. Sorry for such a long question.

• 12.04 black screen crash on flash video with Firefox

  - by rahi

  I just started using ubuntu a few months ago and recently upgraded from 11.10 to 12.04. After a few minutes of watching any video online (StumbleUpon video, YouTube and others), I get a black screen. I am unable to do anything, but reboot at this point (to my limited knowledge). So far, I've tried updating the Adobe Flash plugin via Flash Aid (Firefox Add-on), but that doesn't seem to have worked.

• SDL 1.2 reports wrong screen size

  - by Aaron Digulla

  I have a multi-monitor setup with two displays, both 1920x1200. In games, I can only select resolutions 1920x1200 (like 2560x1200) which makes games unusable. Full screen doesn't work either because it switches one display to 800x600 which means I can't reach the close button... I have to kill the game and then, I have to restore my desktop because all windows are moved/resized. How can I force SDL to use any resolution that I want?

  I'm not much of a techie but my friend who is a software engineer suggested I download ubuntu after my Windows computer was not connecting to certain Wi-Fi networks ( including the one at my house).

• Screen will not load in 11.04 alpha 3

  - by Saad Inam

  After updating from 10.10, there were no problems everything updated fine. I restarted the computer and selected Ubuntu from the boot menu but nothing came. it only shows a a black screen and it allows me to type. I have a feeling that this might be to do with the graphics driver, but how would i get a driver if nothing shows? I have ati radeon 5450 which runs with Catalyst Control Center on Windows. How can fix this?

• Why does the login screen fail to appear?

  - by a different ben

  My system: Dell Precision T3500 nVidia Quadro NVS 295 Ubuntu 12.04 x86_64 (3.2.0-32) Essential problem: On boot my system won't get past the splash screen. I can switch to another virtual terminal and log in, I can also ssh from another system -- so it appears that the problem might be with the display manager. How can I diagnose and fix this problem? More info: From a VT I can issue sudo lightdm restart, and this will bring up the login screen and and I can continue from there. So I do have access to my system. Update-manager recently updated a number of packages, including a bunch of x11 and xorg packages, some nVidia drivers, rpcbind, etc etc. My boot log (if that is any guidance) says the following: fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 rpcbind: Cannot open '/run/rpcbind/rpcbind.xdr' file for reading, errno 2 (No such file or directory) rpcbind: Cannot open '/run/rpcbind/portmap.xdr' file for reading, errno 2 (No such file or directory) /dev/sda1: clean, 597650/1525920 files, 3963433/6103296 blocks /dev/sda7: clean, 11/6406144 files, 450097/25608703 blocks /dev/sda5: clean, 158323/1525920 files, 1886918/6103296 blocks /dev/sda8: clean, 250089/107929600 files, 111088810/431689728 blocks Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox Skipping profile in /etc/apparmor.d/disable: usr.sbin.rsyslogd * Starting AppArmor profiles [80G [74G[ OK ] Loading the saved-state of the serial devices... /dev/ttyS0 at 0x03f8 (irq = 4) is a 16550A * Starting ClamAV virus database updater freshclam [80G [74G[ OK ] * Starting Name Service Cache Daemon nscd [80G [74G[ OK ] * Starting modem connection manager[74G[ OK ] * Starting K Display Manager[74G[ OK ] * Starting mDNS/DNS-SD daemon[74G[ OK ] * Stopping GNOME Display Manager[74G[ OK ] * Stopping K Display Manager[74G[ OK ] * Starting bluetooth daemon[74G[ OK ] * Starting network connection manager[74G[ OK ] * Starting Postfix Mail Transport Agent postfix [80G [74G[ OK ] speech-dispatcher disabled; edit /etc/default/speech-dispatcher * Starting VirtualBox kernel modules [80G [74G[ OK ] * Starting the Winbind daemon winbind [80G [74G[ OK ] saned disabled; edit /etc/default/saned * Starting anac(h)ronistic cron[74G[ OK ] * Stopping anac(h)ronistic cron[74G[ OK ] * Checking battery state...

• no login screen: problem with lightdm or plymouth?

  - by a different ben

  When I boot up my system, I don't get a login screen, just the boot log scrolling by, repeating after a while lines like this: * Starting anac(h)ronistic cron [ OK ] * Stopping anac(h)ronistic cron [ OK ] I can change to another virtual terminal, and start lightdm from there with sudo lightdm restart or sudo start lightdm. Other people with similar problems had just lightdm in their /etc/x11/default-display-manager. I've checked mine and it has /usr/sbin/lightdm in there, so that's not the problem.

• average screen ratio

  Im building a portfolio website that uses full screen background images slideshow that are cropped to fit using a js plugin. To give the minimum amount of cropping whats the best ratio to make the images ? ie i know 13" macbooks are around 13:7 (when taking into account about 100px for the browser bar) but does that scale up on 15",24",17" displays ? I know there are charts showing the most common dimensions but they just show a range of sizes and thats categorized by groups rather than actual dimensions

• Has anyone got Ubuntu Touch working on Nexus 5?

  - by user1628

  I have been debating whether to get a nexus 5 phone since it came out. My only fear is that I won't like android. I love ubuntu, I know that I'd love ubuntu. So I have a few question related to Ubuntu Touch: Is it easy or possible to switch between Ubuntu Touch and Android? Would I have to keep hacking the phone? Can I dual boot them? Would I lose my data every time I switch? The nexus 5 isn't mentioned here: https://wiki.ubuntu.com/Touch/Devices Does that mean it simply won't work if I follow the porting instructions? Would I have to do a bit of hacking? Has anyone got it working? Will it eventually be supported?

• How will the launcher/button work on a touch panel?

  - by burli

  I'm not sure if Unity has a design problem. If the Launcher is hidden you can bring it to front by moving the mouse over the home button or hit the Super Key. So far, so good. But what is on Tablet Devices with touch panel? Intuitively I would "click" in the corner to show the launcher, but a click will open the Dash. How should that work on a touch device? Do I have to "drag" my finger into the corner? Will touch devices have a "menu button"? Will there be a gesture to show the launcher?

• How to reinstall latest Ubuntu Touch on Nexus 4?

  - by Galen Gruman

  I've followed the instructions on https://wiki.ubuntu.com/Touch/Install, first doing the steps that lead to phablet-flash -b and then the manual ones. In both cases, I get stuck at the Google boot screen. It does not boot into Touch. No errors during manual install, and adb devices shows the device, but I get the following with phablet-flash or phablet-flash -b (second and subsequent times, not the first time): Device detected as /system/bin/sh: getprop: not found Unsupported device, autodetect fails device When working on flipped images, detection does not work and would require -d Not clear what that all means. The Nexus 4 had the initial Touch dev preview on it, FYI. I saw no separate instructions for upgrading from that.

• Building a touch event driven UI from scratch: what algorithms or data types?

  - by user1717079

  I have a touch display. As input I can receive the coordinates and how many touch points are in use, basically I just get an X,Y couple for every touch event/activated point at a customizable rate. I need to start from this and build my own callback system to achieve something like Object.onUp().doSomething() meaning that I would like to abstract just the detection of some particular movements and not having to deal with raw data: what algorithms can be useful in this case? What statements? Is there some C++ library that I can dissect to get some useful info? Would you suggest the use of an heuristic algorithm?

• iPhone: Tracking/Identifying individual touches

  - by FlorianZ

  I have a quick question regarding tracking touches on the iPhone and I seem to not be able to come to a conclusion on this, so any suggestions / ideas are greatly appreciated: I want to be able to track and identify touches on the iphone, ie. basically every touch has a starting position and a current/moved position. Touches are stored in a std::vector and they shall be removed from the container, once they ended. Their position shall be updated once they move, but I still want to keep track of where they initially started (gesture recognition). I am getting the touches from [event allTouches], thing is, the NSSet is unsorted and I seem not to be able to identify the touches that are already stored in the std::vector and refer to the touches in the NSSet (so I know which ones ended and shall be removed, or have been moved, etc.) Here is my code, which works perfectly with only one finger on the touch screen, of course, but with more than one, I do get unpredictable results... - (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { [self handleTouches:[event allTouches]]; } - (void) touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event { [self handleTouches:[event allTouches]]; } - (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event { [self handleTouches:[event allTouches]]; } - (void) touchesCancelled:(NSSet*)touches withEvent:(UIEvent*)event { [self handleTouches:[event allTouches]]; } - (void) handleTouches:(NSSet*)allTouches { for(int i = 0; i < (int)[allTouches count]; ++i) { UITouch* touch = [[allTouches allObjects] objectAtIndex:i]; NSTimeInterval timestamp = [touch timestamp]; CGPoint currentLocation = [touch locationInView:self]; CGPoint previousLocation = [touch previousLocationInView:self]; if([touch phase] == UITouchPhaseBegan) { Finger finger; finger.start.x = currentLocation.x; finger.start.y = currentLocation.y; finger.end = finger.start; finger.hasMoved = false; finger.hasEnded = false; touchScreen->AddFinger(finger); } else if([touch phase] == UITouchPhaseEnded || [touch phase] == UITouchPhaseCancelled) { Finger& finger = touchScreen->GetFingerHandle(i); finger.hasEnded = true; } else if([touch phase] == UITouchPhaseMoved) { Finger& finger = touchScreen->GetFingerHandle(i); finger.end.x = currentLocation.x; finger.end.y = currentLocation.y; finger.hasMoved = true; } } touchScreen->RemoveEnded(); } Thanks!
