• List of Appindicators

  - by user8592

  I installed Ubuntu 11.04 on one of my systems and I am using Unity interface. Unity is working quite nice so far but i really miss panel applets for net speed, cpu temp, and system monitor. These applets show useful quickinfo and unlike 10.10 there is no way to get these on panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know then please list out any third party indicators with links so that they can be found at one place.

• My computer will no longer suspend or shut off when I close the lid

  - by dave

  This is somewhat annoying. I have an old laptop and the screen on it is shot, so now I have an old monitor hooked up and it works fine. Before the upgrade I had it set so that when i closed the lid on the laptop everything would shutdown or suspend, when I lift the lid, everything would come back. Now, however, when i close the lid nothing happens, when i open the lid the screen flashes black and comes back. I have it set so that it should suspend when i close the lid. It's confusing...

• How to create an Orthographic display in OpenGL (ES) that handles different screen sizes and orientations?

  - by Piku

  I'm trying to create an iPad/iPhone game using GLES2.0 that contains a 3D scene with a heads-up-display/GUI overlaid on the top. However, this problem would also apply if I were to port my game to a computer and run the game in a resizable window, or allow the user to change screen resolutions... When trying to make the 2D GUI/HUD work I've made the assumption that all I'm really doing is drawing a load of 2D textured 'quads' on the screen and am trying to treat the orthographic projection as an old-style 2D display with 0,0 in the upper left and screenWidth,ScreenHeight in the lower right. This causes me all sorts of confusion when I rotate my ipad into Landscape mode since I can't work out what to put into my projection and modelview matrices to turn everything around the right way. It also gets messy if I want to support the iPad's large screen, an iPhone or a Retina display since I have to then draw three sets of textures for everything and work out which ones to use. Should I be trying to map the 2D OpenGL co-ords 1:1 with the screen? While typing out this question it occurs to me that I could keep my origin in the centre, still running -1/+1 along the axes. This would let me scale my 2D content appropriately on the different screen sizes, but wouldn't I end up with the textures being scaled and possibly losing quality? I'm using OpenGLES 2.0 and have a matrix library that has equivalents to the GLES1.1 glOrthof() and glFrustrum() calls.

• How can I configure the login screen to be displayed in portrait orientation?

  - by rocket101

  I just started using linux, and I have one question. I have a monitor that I rotated 90? clockwise, so it, being rectangle shaped, is taller than it is wider. Using the system settings in Ubuntu, I set it up, and it works great, except the login screen and loading screen are not rotated right. They are rotated in the "normal" way. Is this just a glitch, or is there some setting I overlooked? I am using the open source drivers, and it is an ATI card, if that matters.

• Are Remote commit hooks in subversion possible?

  - by John Hamelink

  Hi there, my current setup is as follows: We have a Linux samba share that contains all the repository folders (with the hooks folder inside, amongst the others) All the developers have the share mapped as a network drive, and import to a local directory (normally C:\Server\RepositoryName) where they work on their files. All the machines accessing the drive (unfortunately) run windows. What I'm aiming to do is to have a hook on the Linux server that detects when a commit has been made, by which project, the revision number, the name of the developer who committed, etc. I looked into the hooks files, but they seem to be ran by the client. Is there a way to monitor svn changes and collect the relevant information from the Linux server?

• How to make Box2D bodies automatically return to a initial rotation

  - by sm4

  I have two long Box2D bodies, that can collide while moving one of them around with MouseJoint. I want them to try to hold their position and rotation. Blue body is moved using MouseJoint (yellow) towards the Red body. Red body has another MouseJoint - Blue can push Red, but Red will try to return to the start point thanks to the MouseJoint - this works just fine. Both bodies correctly rotate along the middle. This is still as I want. I change the MouseJoint to move the Blue away. What I need is both bodies return to their initial rotation (green arrows) Desired positions and rotations Is there anything in Box2D that could do this automatically? The MouseJoint does that nicely for position. I need it in AndEngine (Java, Android) port, but any Box2D solution is fine. EDIT: By automatically I mean having something I can add to the object "Paddle" without the need to change game loop. I want to encapsulate this functionality to the object itself. I already have an object Paddle that has its own UpdateHandler which is being called from the game loop. What would be much nicer is to attach some kind of "spring" joint to both left and right sides of the paddle that would automatically level the paddle. I will be exploring this option soon.

• Securing Mobile Apps in a Bring Your Own Device World

  - by Naresh Persaud

  As more and more business users begin using their personal devices to access corporate information and resources, the number of network access requests has risen dramatically.  Access Management products and strategies that were based on an employee accessing network resources from a single desktop PC were never designed to monitor and manage an employee that is using a desktop and a laptop, a tablet, and a smartphone all from outside the corporate network, and possibly from an unsecured wireless public network. A new approach is needed to manage the types and frequency of mobile app access requests - an integrated Platform Approach to Identity and Access Management that is location and device aware, that can warn you of unusual or high risk access.  A platform that provides standard APIs so you can manage your mobile apps the same way that you manage your enterprise apps. View the slideshow below to see how the Oracle Identity Management platform can help you secure your mobile applications and data in a Bring Your Own Device World.

• What hinders Ubuntu from getting traction in the professional field? [closed]

  - by Prasad

  If this is not the place to ask this, please forgive this Ubuntu cub, I want to ask, what do people do with Ubuntu? As an Ask Ubuntu user I can see that most of the users (including myself) are asking questions about entertainment related problems. Is that all? No commercial use with it? Do people make fun of Ubuntu or just pretending to be Ubuntu users and use Windows secretly? Please don't hate me or make fun of me, I know lots of people trying to make Ubuntu even better, and I know it's better than Windows (if Adobe software just work on Ubuntu, I won't see Windows logo on my monitor anymore). What hinders Ubuntu from getting traction in the professional field?

• unable to enter bios

  - by fraz

  I have an asus desktop ( amd phenom X6 processor) which was preinstalled with windows 7. I wanted to install ubuntu on it (dual boot) but am unable to do so because of the boot order. So I thought of changing boot order thru bios. But it turns out, if I press any key while the computer is starting, it just doesnt boots. I can see that the keyboard and mouse are booted up. (the lights are on) but the monitor is in standby mode.. I tried tab, f2,f10, delete key. But nothing is working.. Is there a software or other alternate on how can I change boot order ? Thanks

• Wireless USB Adapter driver configuration

  - by Jones

  First I would like agree one thing that this is fully for Ubuntu, not for BackTrack. However I'm posting my BackTrack question here since I find similar problems in backtrack forum are being unanswered and Linux/Unix site of StackExchange has very low attraction. I'm having USB wifi adapter (iBall Baton), having chipset RTL8191SU. It displays available wifi networks in Wicd manager. But while trying to connect it gives me bad password. When I'm trying to run airmon-ng it didn't returned me the monitor mode. I tried to replace with Ubuntu 12.10 drivers. But it totally nulled the device functionality. However I restored the drivers. I'm interested to compile drivers as if anyone indicate the methods. Awaiting ideas!

• Dell XPS 15 with Ubuntu 12.10 and HDMI working on hybrid graphics

  - by karolsojko

  So there is a lot of buzz about hybrid graphics being shitty and having a weak support. I'm currently considering buying a new laptop. Dell XPS 15 caught my eye. I will use it for work as well so I will need a large monitor for it connected by HDMI. The question is: has someone got a Dell XPS 15 and can confirm that hybrid graphics support is working fine on 12.10 with no issues on the HDMI. I ask this because all the buzz about the subject stops on 12.04 - does this mean that it's all ok now :) ?

• Ubuntu 12.4 cursor changes

  - by mantic0

  I have a weird problem with my Ubuntu 12.4 dual screen setup (Toshiba laptop + one monitor). After a while the cursor on one screen completely changes its shape (not every time). I don't really know how to describe it because it's always something else. Sometimes I get four or five vertical lines instead of a cursor, sometimes I can only see part of the cursor, etc, sometimes weird shade appears. This only happens on one screen simultaneously. If I go to the other screen, the cursor appears to be fine but when I change screens, the cursor changes. I tried to do a screenshot but when I do, the cursor looks just fine. I'm using Unity and Gnome 3 but the problem is on both desktop environments. Nothing is wrong with my screen though because I'm also using Windows and I don't have any problems there.

• Change Logging Level for SOA 11g

  - by James Taylor

  I’m sure there are many blogs out there that have this solution. But I seem to get asked this question a lot so I thought I would post it here for my convenience. Login to Enterprise Manager, e.g. http://localhost:7001/em Expand the SOA folder and right-click the soa-infra(soa_server1) folder and select Logs – Log Configuration Navigate to the component you want to monitor and change the log level. It is possible to change at a parent level if required It is not recommended that you set the level to FINIEST at a parent level as it will generate a lot of logging. Make sure you apply the change to take affect. Simple as that.

• Infrared usb adapter not hot pluggable?

  - by A. Goossens

  For transferring exercise files from my Polar heart rate monitor i use the software Protrainer 5 with an external infrared usb adapter. Using Wine to run Protrainer 5 and some adjustments mentioned here (using irda-utils) i managed to make it work. Well, sort of: every time i want to transfer exercise files and the adapter is not plugged in i have to reboot my laptop with the usb adapter plugged in to make it work. Since i have a laptop it unfortunately is no option to just always leave the adapter in. It seems to me that the usb adapter isn't hot pluggable (which seems odd for a usb device) or there must be another problem. Polar WebLink (other software to transfer exercise files) experiences the same issue. Can anyone help me to fix this problem? Infrared usb adapter: Polar IRDA USB adapter OS: Ubuntu 12.10 (64-bit) Hardware: Lenovo Thinkpad T500

• window borders, menu bar missing over VNC

  - by zacaj

  I'm running Ubuntu 14.04 with Unity and Gnome3, however I don't have a screen hooked up anymore. I have installed x11vnc and run it with "-create" so that it will create a new X11 session, however when I VNC to it, the menu bar, window borders, etc are missing, windows are ordered based on creation time, and cannot be resized. Now, I don't really care if I end up with Ubuntu or Gnome's window manager, as long as this doesn't mess up my normal desktop stuff if I should happen to hook a monitor up again, and I'm not even attached to x11vnc if someone can point me to a good complete tutorial using something else, but I've been trying vino and tightvnc and rdp and x11vnc is the only one I've managed to get this far.

• update-apt-xapian-index uses 100% CPU, even when Update Manager is set to not check for updates

  - by Dave M G

  I have a slightly older laptop running Ubuntu 11.10. It runs fine, but frequently, when I start it up, the CPU monitor in my Gnome Panel shows 100% usage for for what can be up to five minutes or so. It seems that the offending process is update-apt-xapian-index, which, if I understand correctly, is the update manager checking for updates. I have gone into the update manager settings, and selected to never check for updates. I'll do that manually when I feel like I have the time to leave the laptop running for that. However, despite my selection, this still happens. Roughly 50% of the time or more, when I start my laptop, it runs update-apt-xapian-index. How can I get the update manager to respect my settings, or at least to get this process to stop eating my CPU cycles?

• does anyone know why apt-cacher-ng always downloading index file (Packages.gz) even though its exist on the apt-cacher-ng's cache?

  - by soekarmana

  just updated from 11.04 to 12.04, fresh install installed apt-cacher-ng and notice something strange about it its always downloading index file (Packages.gz) even though the file exist on the apt-cacher-ng's cache, so this is what exactly happened : on ubuntu 10.10 & 11.04 apt-cacher-ng installed & configured on my laptop, then i reload & install some packages after that i configure my friend's laptop with apt-cacher-ng proxy (192.168.1.1:3142), reloading repository was blazingly fast, finished in a second without using my Internet connection (checked on system monitor, total Received just 15kB) on ubuntu 11.10 & 12.04 apt-cacher-ng installed & configured on my laptop, then i reload & install some packages after that i configure my friend's laptop with apt-cacher-ng proxy (192.168.1.1:3142), reloading repository was really slow!, apt-cacher-ng redownload the index file from internet

• Rotating wheel with touch adding velocity

  - by Lewis

  I have a wheel control in a game which is setup like so: - (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(wheel.boundingBox, location)) { CGPoint firstLocation = [touch previousLocationInView:[touch view]]; CGPoint location = [touch locationInView:[touch view]]; CGPoint touchingPoint = [[CCDirector sharedDirector] convertToGL:location]; CGPoint firstTouchingPoint = [[CCDirector sharedDirector] convertToGL:firstLocation]; CGPoint firstVector = ccpSub(firstTouchingPoint, wheel.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(touchingPoint, wheel.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); wheelRotation += (currentTouch - previousTouch) * 0.6; //limit speed 0.6 } } I update the rotation of a the wheel in the update method by doing: wheel.rotation = wheelRotation; Now once the user lets go of the wheel I want it to rotate back to where it was before but not without taking into account the velocity of the swipe the user has done. This is the bit I really can't get my head around. So if the swipe generates a lot of velocity then the wheel will carry on moving slightly in that direction until the overall force which pulls the wheel back to the starting position kicks in. Any ideas/code snippets?

• How do you remember where in your code you want to continue next time?

  - by bitbonk

  When you interrupt the work on some code (be it because you have to work on something else or go on vacation or simply because it is the end of the day), once you close that Visual Studio project, what is your preferred way to remember what you want to do next when you start working on that code again. Do you set a Visual Studio bookmark or do write down something like // TODO: continue here next time? Maybe you have a special tag like // NEXT:? Do you put a sticky note on your monitor? Do you use a cool tool or Visual Studio plugin I should know? Do you have any personal trick that helps you find the place in your code where you left off the last time you worked on your code?

• Screen has 1px vertical dead area on the right side

  - by pileofrocks

  Meaning that I can not click anything on that 1px vertical area (such as scrollbars). Illustration (purple = screen, black = the dead area): I am thinking Compiz has to be the main suspect, especially as on a guest account, this problem does not exist. I have a dual-monitor setup and this does not happen on the 2nd screen. However, turning off the 2nd display does not make any difference. I had this issue already before upgrading to 13.10 and while doing that, I also resetted all Compiz settings and re-loaded my profile configuration file. I have tried disabling all Compiz plugins under "Window Management" What next?

• Input Signal Out of Range 1920x1080

  - by Zach

  I've recently installed Ubuntu 12.04 on my computer. Now, every time I boot and when I shut down, my monitor goes blank and says "Input Signal Out of Range - Change Setting to 1920x1080 60Hz." Once the computer gets to the login screen, it's okay again. This problem also happens when I try to open any 3d app. My graphics card is NVIDIA GEforce 6150 SE. I tried updating the drivers, but it broke everything and I had to reinstall Ubuntu. Any help?

• Track url from Amazon S3 using Google Analytics

  - by morktron

  I couldn't find any decent pay per view video solutions for low budget clients. So I'm considering using a membership extension with Joomla and hosting the video with amazon S3. The only issue is that once someone has signed up to view or download the video if they have any web development experience they will be able to get the url of the video and freely publish it on the web. How can this be prevented? It looks like it can be done using IAM User Temporary Credentials - AWS SDK for PHP but the client would prefer not to have to pay someone to spend hours writing custom php code to get this to work. With Amazon s3 I could at least check the log files I guess to manually monitor the url but is there a way to track the url with Google Analytics? or is there a more elegant solution?

• finding a WUXGA or matte laptop

  - by John Paul Cook

  UPDATED: HP still sells 17" WUXGA laptops - details in the new paragraph at the end. Lenovo, Dell, Sony and Sager do not sell a 1920x1200 (WUXGA) laptop. I understand that manufacturers provide what there is market demand for. I also understand that HDTV and the 1080p standard is heavily influencing both monitor and laptop screen resolutions. But I do not understand why there is so little demand for a WUXGA laptop. Nor do I understand the popularity of glossy displays. I really don't like to look...(read more)

• Apple Cinema Display 23" and grub

  - by Joshua Pruitt

  As per the title, I'm running my display on an older 23" Apple Cinema Display (because I still love it, darn it). I'm pushing it with an ATI Radeon DVI dual-link PCIe card. It works just fine, except GRUB doesn't seem able to push out the 1920x1200 pixel resolution needed in order to show me a boot menu! So..., I keep a smaller second monitor connected as the primary display so that I can see the boot menu and boot the system (I don't use that display once booted). This is a goofy work-around, and I'd like to just use my single display exclusively to boot the machine. I found some grub codes for higher resolutions, but not for 1920x1200. Is it capable of this? Did I just miss it? Thanks in advance!!!
