  • Accessing Secure Web Services from ADF Mobile

    - by Shay Shmeltzer
    Most of the enterprise Web services you'll access are going to be secured - meaning they'll require you to pass a user/password in order to get to their data.  If you never created a secured Web service, it's simple in JDeveloper! For the below video I just right clicked on a Java class that I exposed as a Web service, and chose  "Web Service Properties" and then checked the "oracle/wss_username_token_service_policy" box from the list of options (that's the option supported by ADF Mobile right now): In the demo below we are going to use a "remote" login server that does the authentication of the user/pass.The easiest way to "create" a remote login server is to create a "regular" web ADF application, secure it, and deploy it on a server. The secured ADF application can just require ADF Authentication with a simple HTTP Basic Authentication - basically the next two images in the Application->Secure->Configure ADF Security menu wizard. ok - so now you have a secured ADF application - deploy it on a server and get the URL for that application.  From this point on you'll see the process in the video which deals with the configuration of your ADF Mobile app. First you'll need to enable security for your ADF mobile application, so it will prompt users to provide a user/pass combination. You'll also need to configure security on specific features. And you can have them use remote login pointing to your regular secured ADF application. Next define your Web service data control. Right click on the web service data control to "define Web Service Security". You'll also need to define the adfCredentialStoreKey property for the Web Service data control in the connections.xml file. This should be it. Here is the flow: If you haven't already - you can read more about this in the Mobile developer guide, and Andrejus has a sample for you.

  • Second Monitor Detected, but not receiving a signal after upgrading to 12.04

    - by user62458
    After I upgraded to 12.04, my second monitor is detected (in display settings), but will not power on. I have scoured the Internet and forums for a solution and I can't find anything. I have found a couple people with the same problem, but never a solution for it. I am no expert, but I'm certainly not a noob. My computer uses AMD Radeon 6250 graphics, but I do NOT want to use the proprietary graphics drivers. They refuse to work properly with my second monitor (they ATI drivers will only mirror screens, and I've done everything to try to fix it, and I DON't want mirrored screens) Not to mention that the default open-source video drivers seem to work much better than the proprietary anyway! Again, Ubuntu's default video drivers work fine, and they even DETECT the second monitor (Dell 19'). I can drag stuff off the screen and put it on the 'space' of the second monitor and even a screen-shot shows that there are two monitors active; but the monitor is OFF. It will not power on. It goes into 'power-save' mode because it is not receiving a signal. For some reason it is not getting the signal to power on, even though Ubuntu thinks the monitor is working properly. I had this working fine on my Sony VAIO yesterday (with Radeon graphics/default Ubuntu video drivers). I upgraded to a Samsung Series 3 and now I have this issue. I can't for the life of me figure out why the monitor is connected, detected and I have screen space for the monitor, but the screen won't turn on!

  • Ubuntu 14.04 install fails with Via S3 UniChrome Pro graphics

    - by WizardNo.7
    I am trying to install Ubuntu 14.04 on a Fujitsu Siemens Amilo Pro laptop(it's quite old yes, has about 30GB Hard Drive and I think 192mb of RAM) which currently has Windows XP installed (which I'd like to keep for the time being). I have downloaded the 32-bit Desktop ISO and used unetbootin to create a Live USB for this laptop. When I boot from USB, I arrive at the unetbootin Grey and Blue menu and pick either "Try Ubuntu without installing", or "Install Ubuntu". The menu goes away and an Ubuntu loadscreen showing UBUNTU and four dots which progressively change between white and orange. At about the second color changing cycle a white underscore symbol appears next to the fourth dot and flickers. There is some leftover text from the kernel boot still visible, but there is no graphical desktop. After this I have to hard reboot or shut-down. $ lshw -c video *-display UNCLAIMED description: VGA compatible controller product: CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro] Vendor: VIA Technologies, Inc. physical id: 0 bus info: pci@0000:01:00.0 version: 01 width: 32 bits clock: 66MHz capabilities: pm agp agp-2.0 vga_controller bus_master cap_list configuration: latency=64 mingnt=2 resources: memory:f0000000-f3ffffff memory:d1000000-d1ffffff

  • JEditorPane on Steroids with Nashorn

    - by Geertjan
    Continuing from Embedded Nashorn in JEditorPane, here is the same JEditorPane on steroids with Nashorn, in the context of some kind of CMS backend system: Above, you see heavy reusage of NetBeans IDE editor infrastructure. Parts of it are with thanks to Steven Yi, who has done some great research in this area. Code completion, right-click popup menu, line numbering, editor toolbar, find/replace features, block selection, comment/uncomment features, etc, etc, etc, all the rich editor features from NetBeans IDE are there, within a plain old JEditorPane. And everything is externally extensible, e.g., new actions can be registered by external modules into the right-click popup menu or the editor toolbar or the sidebar, etc. For example, here's code completion (Ctrl-Space): It even has the cool new feature where if you select a closing brace and the opening brace isn't in the visible area, a rectangular popup appears at the top of the editor, to show how the current piece of code begins: The only thing I am missing is code folding! I wish that would work too, still figuring it out. What's also cool is that this is a Maven project.

  • Should Android and iPhone UI be different?

    - by Phonon
    I'm not completely new to developing apps, but I'm at a point where I'm trying to develop something and deploy it on several mobile platforms. To only concentrate on two major ones, suppose I'm developing an app for Android and iPhone and designing UI and the general user interaction architecture. Both platforms give guidelines as to how their UIs should work. For example, most iPhone apps have the Navigation Bar (the one that says Testing 1 and has a Back button) and an Icon Bar for navigating a program, while Android uses an Options Menu fetched via a Menu button and the "back" navigation is handled with the physical Back button on the device. I've seen many apps that try to force the same UI on every platform. For example, custom-building an iPhone style Icon Bar and putting it in their Android apps, but it just doesn't quite look right to me and it feels like it violates UI design guidelines somewhat. Are there any good design patters for implementing something sufficiently similar on both platforms, yet still platform-specific enough so that the user would not feel out of their comfort zone? What do people usually do in these situations?

  • Eliminating zero-length files

    - by RhZ
    I have been having multiple crashes recently. 4-5 last night within a few hours. I posted about it before, and got an answer but not sure how to proceed. The messages in my logs right before the crash are multiple complaints about valid eCryptfs headers. But the chron might not be related, I don't think I saw that in previous crashes: xxx-desktop kernel: [ 1112.274474] Valid eCryptfs headers not found in file header region or xattr region, inode 32376924 xxx-desktop CRON[4212]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) So I was sent to an answer providing this script: for i in find $(mount | grep " on $HOME type ecryptfs" | awk '{print $1}') -size 0c; do if ! fuser -v $i; then rm -f $i fi done I did find some zero byte files, not in the exactly right place (a folder called .private as I remember), but I need to fix this, its too bad right now. So I need to delete any of them that are not in use. I am a little too clueless, can someone walk me through executing this script? I don't know how.

  • Dual displays not working with Xinerama in Ubuntu 12.04

    - by user68489
    I just upgraded from Ubuntu 10.10 to 12.04. I had been using a display configuration just like the one described at http://bitkickers.blogspot.com/2009/08/rotate-just-one-monitor-with.html without any problems under 10.10. I have an nvidia Quadro FX 380 and have upgraded to the latest drivers (295.49). Everything appears to be fine when the system first boots up. However, after logging in, the left screen goes black, and the right screen displays what should be displayed on the left screen. Logging into Ubuntu 2D somewhat improves things. The left screen correctly displays the left portion of the desktop but the right screen contains a duplicate view of the left screen. Turning off Xinerama and enabling TwinView appears to fix the issues but does not allow the right monitor to be rotated. Since the display problems start to occur only after logging on, I thought it might have to do with carryover user configuration from 10.10 but the problems persist even when logging in as a guest. Clicking on System Settings - Displays results in the error message "Could not get screen information - RANDR extension is not present." Any help would be greatly appreciated.

  • Reflection velocity

    - by MindSeeker
    I'm trying to get a moving circular object to bounce (elastically) off of an immovable circular object. Am I doing this right? (The results look right, but I hate to trust that alone, and I can't find a tutorial that tackles this problem and includes the nitty gritty math/code to verify what I'm doing). If it is right, is there a better/faster/more elegant way to do this? Note that the object (this) is the moving circle, and the EntPointer object is the immovable circle. //take vector separating the two centers <x, y>, and then get unit vector of the result: MathVector2d unitnormal = MathVector2d(this -> Retxpos() - EntPointer -> Retxpos(), this -> Retypos() - EntPointer -> Retypos()).UnitVector(); //take tangent <-y, x> of the unitnormal: MathVector2d unittangent = MathVector2d(-unitnormal.ycomp, unitnormal.xcomp); MathVector2d V1 = MathVector2d(this -> Retxvel(), this -> Retyvel()); //Calculate the normal and tangent vector lengths of the velocity: (the normal changes, the tangent stays the same) double LengthNormal = DotProduct(unitnormal, V1); double LengthTangent = DotProduct(unittangent, V1); MathVector2d VelVecNewNormal = unitnormal.ScalarMultiplication(-LengthNormal); //the negative of what it was before MathVector2d VelVecNewTangent = unittangent.ScalarMultiplication(LengthTangent); //this stays the same MathVector2d NewVel = VectorAddition(VelVecNewNormal, VelVecNewTangent); //combine them xvel = NewVel.xcomp; //and then apply them yvel = NewVel.ycomp; Note also that this question is just about velocity, the position code is handled elsewhere (in other words, assume that this code is implemented at the exact moment that the circles begin to overlap). Thanks in advance for your help and time!

    - by darroosh
    I'm new to linux world. Just downloaded ubuntu and installed it alongside with windows 7 . In grub when I choose ubuntu, it opens with no problem, but when I try to open windows 7, this message appears: A Disk Read Error Occured. Press CTRL+ALT+DEL to restart. I googled for that problem which directed me to download a boot repair tool, when I choose : advanced options / retore MBR --> apply, then restart computer , It boot to win 7 without loading the grub menu. then I opened the live ubuntu from a USB, launched the "boot repair" again, choose : recommended repair , then restart, It returns to the first problem , grub menu appear, from which I can choose only ubuntu , but win 7 show this msg again : A Disk Read Error Occured. Press CTRL+ALT+DEL to restart. I repeated more and more with the same results ... What should I do? I created a boot info summary using the "boot repair tool" if this can help , it's in this URL.

  • About C# objects and the possibilties it has

    - by user527825
    As a novice programmer and I always wonder about c# capabilities. I know it is still early to judge that but all i want to know is can c# do complex stuffs or something outside windows OS. I think C# is a proprietary language (I don't know if I said that right) meaning you can't do it outside Visual Studio or Windows. Also you can't create your own controller (called object right?) like you are forced to use these available in toolbox and their properties and methods. Can C# be used with OpenGL API or DirectX API Finally it always bothers me when I think I start doing things in Visual Studio, I know it sounds arrogant to say but sometimes I feel that I don't like to be forced to use something even if its helpful, like I feel (do I have the right to feel?) that I want to do all things by myself? Don't laugh I just feel that this will give me a better understanding. Is Visual C# like using MaxScript inside 3ds max in that C# is exclusive to do Windows and Forms and Components that are Windows related and maxscript is only for 3d editing and manipulation for various things in the software. If it is too difficult for a beginner I hope you don't answer the fourth question as I don't have enough motivation and I want to keep the little I have. Note: Sorry for my English, I am self taught and never used the language with native speakers so expect so errors. I have a lot of questions regarding many things, what is the daily ratio you think for asking (number of questions) that would not bother the admins of the site and the members here. Thank you for your time.

  • Connecting two monitors at the corners

    - by fastmultiplication
    I am using two separate X screens on two monitors and I would like them to be connected at the lower right corner. That is, if you move to the lower right corner of screen0 the mouse should appear at the upper left of screen1. I do not want an entire edge of each monitor to be permeable to the mouse. I modified the xorg.conf file like so: Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" Relative "Screen0" 1200 1000 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection (screen 0's resolution is 1280x1024) so there is a bit of overlap. However whenever I move the mouse to the bottom of screen0, the pointer appears at the upper left of screen1. And, the entire top of screen1 is permeable to the mouse and brings it to the lower left corner of screen0. I have tried various numbers in following the "relative" statement - if I put 1280 1024 the mouse does not cross over at all. If I use 1280 1023 the entire right side of screen0 is permeable. I haven't been able to find any documentation about how to explicitly tell the mouse where to crossover - is there some? It seems that xorg is being really aggressive in guessing where the mouse crossover should take place. Does anyone know how to do this? Thanks!

  • monitor height differences & the mouse going off screen

    - by fastmultiplication
    In ubuntu 10.10 I have a dual monitor setup. I have an nVidia graphics card and am using twinview. One of the monitors is 1024 pixels high and the other is 900. In the monitor configuration screen & in real life, I have them set up side by side, 1024 on the left. The result of this is that when I am on the bottom of the left monitor and move the mouse to the right, it goes into the hidden area below the right monitor's visible area. It seems like it would make a lot more sense for it to be bumped up to the bottom of the right monitor - since one almost never wants to move the mouse into an area of the screen that doesn't show up. And, systems I have used before have been set up that way. How can I set this up? I am not interested in lists of window managers for ubuntu; I would like to know the identity of a particular WM or set of steps I can take to solves the particular problem I have outlined above. Thanks! EDIT: I changed to use two seperate X window monitors, and set them up relatively positioned so that just the corner touches and the mouse can cross there, so the difference in heights doesn't matter.

  • Windows Recovery from Grub messed up my computer?

    - by Hudson Worden
    Ok so I'm a noob when it comes to Operating Systems and I think I really messed up this time. So I have a laptop that dual boots Windows 7 and Linux Mint 11. I was trying to boot into Windows 7 but it would just have a black screen with a blinking cursor. So I turned off my computer and tried again. Still a black screen with a cursor. So I thought "well it must be broken somehow and I remembered seeing something like 'Windows Recovery' from the boot menu so I should try it." So when I turned on my computer a third time I selected 'Windows Recovery' (Something like that I can't remember exactly what it was called). After I had selected that I got a white Windows window that said in big red letters "ERROR". I turned off my computer again a turned it back on expecting the Grub menu to reappear. I was wrong. Instead I am greeted with error: no such partition grub rescue. Then I put in a live CD for ubuntu 11.04 and tried looking at my partitions using the disk manager. Looking at my partitions I notice that there isn't a Linux partition anymore and in its place is a unallocated space partition yet the Linux Swap partition is still there. My windows partition is still fine and I can access the files in it. If you understand what has happened, is there anyway I can get my files back? I don't care about reinstalling the OS again. I just want those files that are in the Linux Mint partition.

  • At the Java DEMOgrounds - ZeroTurnaround and its LiveRebel 2.5

    - by Janice J. Heiss
    At the ZeroTurnaround demo, I spoke with Krishnan Badrinarayanan, their Product Marketing Manager. ZeroTurnaround, the creator of JRebel and LiveRebel, describes itself on their site as a company “dedicated to changing the way the world develops, tests and runs Java applications."“We just launched LiveRebel 2.5 today,” stated Badrinarayanan, “which enables companies to embrace the concept and practice of continuous delivery, which means having a pipeline that takes products right from the developers to an end-user, faster, more frequently -- all the while ensuring that it’s a quality product that does not break in production. So customers don’t feel the discontinuity that something has changed under them and that they can’t deal with the change. And all this happens while there is zero down time.”He pointed out that Salesforce.com is not useable from 3 a.m. to 5 a.m. on Saturday because they are engaged in maintenance. “With LiveRebel 2.5, you can unify the whole delivery chain without having any downtime at all,” he said. “There are many products that tell customers to take their tools and change how they work as an organization so that you they have to conform to the way the tool prescribes them to work as an application team. We take a more pragmatic approach. A lot of companies might use Jenkins or Bamboo to do continuous integration. We extend that. We say, take our product, take LiveRebel okay, and integrate it with Jenkins – you can do that quickly, so that, in half a day, you will be up and running. And let LiveRebel automate your deployment processes and all the automated tasks that go with it. Right from tests to the staging environment to production -- all with zero downtime and with no impact on users currently using the system.” “So if you were to make the update right now and you had 100 users on your system, they would not even know this was happening. It would maintain their sessions and transfer them over to the new version, all in the background.”

  • Can't boot after compiling 3.1 kernel, can only get to terminal

    - by olssy
    Long story short: I tried compiling kernel 3.1 on Ubuntu 11.10 at the same time I had an update waiting for a reboot. Computer would boot to a black screen and would hang there. Ended up installing 11.10 on top of old install with a Live CD. Now I had a purple screen on bootup but it would end up booting. Realized Grub was the problem and tried some stuff but nothing worked. I ended up trying to install propriety ATI video drivers and since that nothing has worked, no grub menu(purple screen) and when it boots into the kernel it ends up hanging, I can sometimes get a terminal up with alt-fx. I have tried removing the ati drivers with the ati script, purging my fglrx driver, reconfiguring my xconf.org and following any tutorial I can find about fixing a broken graphics driver, but to no avail. I've gotten to a point were it seems that the ati propriety drivers are correctly loaded but it still has no grub boot menu and won't boot into Ubuntu. I've chased down my logs and this line is from kern.log: unity-greeter[3269]: segfault at 0 ip b7245cbbsp bf9d3900 error 4 in libgio-2.0.so.0.3000.0[b71ad000+142000] That line leads me to believe I don'T have the correct libgio-2 librairy on my system but have no idea how to find out what package has the correct version... My xorg.conf has no errors and seems to imply the fglrxdrm module got loaded correctly. Would be a bit complicated pasting the whole file here but if it would help I'll post it. LAstly, running fglrxinfo give me: Error: Unable yo open display (null) Any help or link to another tutorial would be appreciated. Thanks.

  • Two Hidden NetBeans Keyboard Shortcuts for Opening & Toggling between Views

    - by Geertjan
    The following are two really basic shortcuts for working with NetBeans editor windows that will be added to the Keyboard Shortcuts card for NetBeans IDE 7.2: Ctrl-Alt-PgUp/PgDown: Shortcuts for switching between editor types (e.g. Source, Design, History buttons). Switching between the editor types is a frequent operation sometimes, e.g., when using GUI builder, and while it can be done easily via mouse, or from View | Editors menu, it is very handy to know the shortcuts as well. Ctrl-PgUp/PgDown: Similarly, these are shortcuts for switching to next/previous opened document (tab). Note this is not like Ctrl-Tab that cycles in the last used order, but going through the tabs as they appear in the editor. Both shortcuts should fit into the "Opening and Toggling between Views" section. These are important to mention on the card because they are not visible anywhere else in the UI (as there are no menu items like "Go to next/previous editor type" or "Go to next/previous document"). Reported by Tomas Pavek from the NetBeans Team, here: http://netbeans.org/bugzilla/show_bug.cgi?id=213815

  • Nvidia driver installation results in resolution change to 800x600 with Xubuntu 10.04 (can't change)

    - by Jim Michael
    I have a 2.8 P4 and a Nvidia FX 5500 AGP graphics card. I've installed Xubuntu 10.04. It is WAY too laggy with the default o/s driver. Installing the Nvidia 173 driver, modaliases and nvidia-settings packages via synaptic package manager results in the following error message: An error occurred, please run Package Manager from the right click menu or apt-get in a terminal to see what is wrong. Error: Opening the cache (E::read, still have 11898251 to read but none left, E: The package lists or status file could not be parsed or opened.) This usually means that your installed packages have unmet dependencies. When restarting the PC the resolution drops to 800x600 (from the monitors native 1440x900). Nvidia settings cannot be changed either from the Xfce menu or Nvidia Xserver. Nvidia Xsever gives the following error message: You do not appear to be using the Nvidia X driver. Please edit your x configuration file (just run 'nvidiaxconfig' as root ) and restart X server. Also, I can't find anything in any directory called xorg.

  • A Dozen USB Chargers Analyzed; Or: Beware the Knockoffs

    - by Jason Fitzpatrick
    When it comes to buying a USB charger one is just as good as another so you might as well buy the cheapest one, right? This interesting and detailed analysis of name brand, off-brand, and counterfeit chargers will have you rethinking that stance. Ken Shirriff gathered up a dozen USB chargers including official Apple chargers, counterfeit Apple chargers, as well as offerings from Monoprice, Belkin, Motorola, and other companies. After putting them all through a battery of tests he gave them overall rankings based on nine different categories including power stability, power quality, and efficiency. The take away from his research? Quality varied widely between brands but when sticking with big companies like Apple or HP the chargers were all safe. The counterfeit chargers (like the $2 Apple iPad charger knock-off he tested) proved to be outright dangerous–several actually melted or caught fire in the course of the project. Hit up the link below for his detailed analysis including power output readings for the dozen chargers.

  • Can't access computer

    - by Pudica
    I'm running Ubuntu 14.04 on an Intel NUC and it won't boot! The last successful boot was earlier today but now each time I try it gets stuck on the Grub menu where it prompts for memory check etc. This is not a dual boot system, so this screen shouldn't ever appear, and it never has before. It's GRUB version 2.02~beta2-9, which is a little disconcerting, as I'm on the stable sources. Unfortunately the keyboard (I've tried 2 keyboards just in case) is not responding at this point in the boot process, so I can't select the "Ubuntu" menu option in Grub. The keyboard works during the bios stage, so I can configure it to boot from USB, and I tried a flash drive with 14.04 on it. The flash drive works in my laptop but is completely ignored by the NUC (I tried all 3 USB ports!). It seems that I have no way of getting into the machine at all! The Intel support site was my first option, but the site is down. I expect it's a long shot, but if anyone has any ideas I'd be very grateful.

  • Game Asset Management

    - by user964123
    I am making my first small mobile game in C# XNA. Lets say I have 3 screens, the main menu, options and game screen. A single game session usually lasts for 1 min, so the user will alternate frequently between the main menu and game screen. Therefore, once I load the textures for either screen, I want to keep them in memory to avoid frequent reloading. Both screens share some assets like their background textures, but differ in others. The first solution I came up with is making 2 texture factory classes, MainScreenAssetFactory and GameScreenAssetFactory, each with their own content manager, and ill store them in a globally accessible point so that they persist after either screen is destroyed. There is also a OptionsScreenAssetFactory, but that I dont want to cache it since the options screen is rarely visited. A typical Factory would look something like this public class MainScreenAssetFactory { private readonly ContentManager contentManager; public MainScreenAssetFactory(IServiceProvider serviceProvider, string rootDirectory) { contentManager = new ContentManager(serviceProvider) { RootDirectory = rootDirectory }; } public Texture2D ListElementBackground { get { return return contentManager.Load<Texture2D>("UserTab"); } } public Texture2D ListElementBulletPoint { get { return return contentManager.Load<Texture2D>("TabIcon"); } } public Texture2D LoggedOutUser { get { return return contentManager.Load<Texture2D>("LoggedOutUser"); } } } Since both Main, Options and Game Screen share some common resources, instead of loading them more than once, I created another class CommonAssetTexFactory which holds the common stuff and stays in-memory during the app lifetime. For example, this class gets passed to the options screen when it is created. However, given my small game with its few assets, I am already finding this solution cumbersome and inflexible. Changing anything would require looking to see if its already in the common factory, and if not, modifying existing factories and so on. And this is just considering textures currently, i didnt add sound files yet. I cant imagine bigger games with thousands of resources using this approach. A better idea must exist. Would someone please enlighten me?

  • Ubuntu 12.04 Full Screen without Unity Hub

    - by Xatolos
    I couldn't find an answer for this, so I thought I would try here. My problem is, I have some games on Wine that play in full screen mode but I can't really get them in full screen mode. When they start up, they end up with the GUI's "HUD" overlapping the game which is really annoying and well kills the option to play the game. This has also happened in a few of my Linux programs as well. While I wrote its a problem with Unity, it really isn't limited to this though. I've done full screen mode on Unity and had the Unity side bar and top menu overlap, I've used Gnome and had the same issue happen, Gnome menu is in the top, Cinnamon had the same issue. Sometimes if I Alt-Tab out of it and back into the program it MIGHT remove the HUD but that doesn't always work, and lets face it, full screen mode that is killed by the GUI just isn't something that can really be ignored. Any suggestions or help would be highly welcomed. My laptop http://www.cnet.com/laptops/asus-g53jw-a1-15/4507-3121_7-34210244.html edit Seems so far to be an issue with Unity and Gnome being in 3D mode, and possibly an issue with my NVidia card and XServe (I think that was it...). Going to Unity/Gnome 2d modes seem to help with this for the moment...

  • after upgrade from 10.04 to 12.04 cannot boot with linux 3.2.0-24-generic-pae

    - by Ricardo
    After upgrade from 10.04 to 12.04, I cannot boot with linux 3.2.0-24-generic-pae: process gets frozen in a xubuntu initialization screen (I had qimo installed). If I try the recovery mode (with the same Linux version), booting freezes after this message: Begin: Mounting root file system. If in grub menu I choose Previous Linux versions, I can boot using Linux 2.6.32-41-generic-pae. But once logged in, some things don't seem to work (apt-get update fails, update manager fails, HID menu does not provide suggestions...) (to be honest, I have no idea whether this is part of the bigger issue) Reading in Ask Ubuntu through apparently similar problems, I decided to follow some advices: got boot-repair and run it. The problem remains & I got this report. I also run as root in terminal $ sudo update-initramfs -u and this is what I got: update-initramfs: Generating /boot/initrd.img-3.2.0-24-generic-pae cryptsetup: WARNING: failed to detect canonical device of /dev/sda1 cryptsetup: WARNING: could not determine root device from /etc/fstab /tmp/mkinitramfs_EIDlHy/scripts/classmate-bottom/45xconfig: 9: .: Can't open /scripts/casper-functions What else? My pc is Intel® Core™ i7 CPU 870 @ 2.93GHz × 8, graphs is GeForce 8400 GS/PCIe/SSE2, memory is 7,8 GiB. I have two questions: Is this a bug in the newest kernel I should report? Is there anything I can do appart from a fresh install?

  • Touchpad not working after connecting hdmi cable

    - by user286632
    I had installed Ubuntu 14.04 2 weeks back on my new laptop along side Windows 8. 1. And it was working fine. But yesterday after I connected Ubuntu with my TV using the HDMI cable, the cursor/ pointer stopped working. The pointer is not visible and my touchpad is not working. I connected the hdmi cable with youtube in Firefox. But only the wallpaper was visible on the TV. Also the right click menu, alt tab window, etc was also visible. But the side menu and the Firefox window was not visible. The pointer was visible on the tv and the touchpad was working, I was able to move the pointer. After I removed the HDMI cable, my cursor/pointer disappeared and my touchpad is not responding! ! I tried to restart many times, but still no luck. Its still not visible in the desktop. The pointer is visible in the login screen, but is not responding to the touchpad. I tried to login to my KDE session, there too the pointer is visible but is not responding to the touchpad. It is not moving.
