  • SFML - Moving a sprite on mouseclick

    - by Mike
    I want to be able to move a sprite from a current location to another based upon where the user clicks in the window. This is the code that I have: #include <SFML/Graphics.hpp> int main() { // Create the main window sf::RenderWindow App(sf::VideoMode(800, 600), "SFML window"); // Load a sprite to display sf::Texture Image; if (!Image.LoadFromFile("cb.bmp")) return EXIT_FAILURE; sf::Sprite Sprite(Image); // Define the spead of the sprite float spriteSpeed = 200.f; // Start the game loop while (App.IsOpened()) { if (sf::Keyboard::IsKeyPressed(sf::Keyboard::Escape)) App.Close(); if (sf::Mouse::IsButtonPressed(sf::Mouse::Right)) { Sprite.SetPosition(sf::Mouse::GetPosition(App).x, sf::Mouse::GetPosition(App).y); } // Clear screen App.Clear(); // Draw the sprite App.Draw(Sprite); // Update the window App.Display(); } return EXIT_SUCCESS; } But instead of just setting the position I want to use Sprite.Move() and gradually move the sprite from one position to another. The question is how? Later I plan on adding a node system into each map so I can use Dijkstra's algorithm, but I'll still need this for moving between nodes.

  • Low graphic mode after switching to fglrx drivers

    - by MrKenkadze27
    I have another problem on my laptop after trying to fix another issue. So, because of this issue, I wanted to switch to fglrx to fix it and after restart, I got this screen: I went back to terminal and I got rid of this problem by "purge"-ing the fglrx driver and removing it, going back to problem number one. I tried lot of methods to fix this such as this ones but they ether switched back to open-source drivers or didn't helped at all. So would anyone like to help? maybe give some commends to try? My Laptop has 2 GPU, AMD Radeon HD 7650M and Intel(R) HD Graphics 4000. AMD is running always making my laptop too hot. Here's one of the Xorg.5.log file paste, I am sure it will be useful finding my problem. Thanks! Please make answer easy to understand as I am not an expert, this problem is keeping me from being one. Also the AMD driver which can be downloaded from their site doesn't install, it says non compatible graphics card but Ubuntu Software Updater sure installs it.

  • something is downloading in background Linux

    - by wisdom
    My laptop boots normally to Linux -LinuxMint- and immediately I like to open gnome-system-monitor but the shock is that something is downloading(the problem has been out 2 days ago) and nothing I run yet ! I did iftop in terminal but nothing strange -a screen shot provided-, also I tried nethogs which showed nothing at all. The more complicated when I reboot and same problem is there so I can't browse/surf Internet, no one connected to my network can browse any more it's absorbing the stream horribly! After many reboots it will go to normal state(no background downloading). But really I can't figure out the problem going behind the scene ! Any suggestion,any help would be appreciated...thanks

  • How to hide the mouse cursor

    - by MvG
    I'm building a kiosk using Ubuntu Precise on a touch screen. Now I'm looking for the appropriate way to make the mouse cursor disappear. As people know where they are pointing, displaying an arrow under their finger is useless, and having an error where they last pointed even more so. My best bet would be some kind of cursor theme consisting only of transparent cursors. I'm a bit surprised to find no UI to switch and maybe install cursor themes the default Unity UI, but as I won't be using Unity, that's not much of a problem. It appears that the alternatives listed in update-alternatives --list x-cursor-theme all refer to .theme files, so I searched the package list for those. The resulting list does not list any likely candidates, i.e. no packages containing “invisible” or “transparent” in their name. So far, some googled result yielding a readme for “XCursor Transparent Theme” is my best bet. That would mean compiling those sources myself, perhaps putting them into my PPA. I'm also a bit sceptical about that result as said readme is dated from 2003. And I'm not sure that I'm not making things overly complicated. After all, there is quite some support in Precise for touch devices, so I don't believe I'm the first one who wants to get rid of his mouse cursor. Is there another way which doesn't involve user-compiled binary code? Is there a theme package for transparent cursors which I've overlooked? Is there some other mechanism to make the cursor disappear without changing the cursor theme? I'll be using Matchbox WM, Firefox and Java applets, so I'll be happy with any solution working under such a setup. I'm not interested in any solutions twiddling with Gnome or Compiz, as I'll not be running either.

  • Regulating how much to draw based on how much was drawn last frame.

    - by Mike Howard
    I have a 3D game world on an iPhone (limited graphics speed), and I'm already regulating whether I draw each shape on the screen based on it's size and distance from the camera. Something like... if (how_big_it_looks_from_the_camera > constant) then draw What I want to do now is also take into account how many shapes are being drawn, so that in busier areas of the game world I can draw less than I otherwise would. I tried to do this by dividing how_big_it_looks by the number of shapes that were drawn last frame (well, the square root of this but I'm simplifying - the problem is the same). if (how_big_it_looks / shapes_drawn > constant2) then draw But the check happens at the level of objects which represent many drawn shapes, and if an object containing many shapes is switched on, it increases shapes_drawn lots and switches itself back off the next frame. It flickers on and off. I tried keeping a kind of weighted average of previous values, by each frame doing something like shapes_drawn_recently = 0.9 * shapes_drawn_recently + 0.1 * shapes_just_drawn, but of course it only slows the flickering down because of the nature of the feedback loop. Is there a good way of solving this? My project is in Objective-C, but a general algorithm or pseudo-code is good too. Thanks.

  • NHibernate Tools: Visual NHibernate

    - by Ricardo Peres
    You probably know that I’m a big fan of Slyce Software’s Visual NHibernate. To me, it is the best tool for generating your entities and mappings from an existing database (it also allows you to go the other way, but I honestly have never used it that way). What I like most about it: Great support: folks at Slyce always listen to your suggestions, give you feedback in a timely manner, and I was even lucky enough to have some of my suggestions implemented! The templating engine, which is very powerful, and more user-friendly than, for example, MyGeneration’s; one of the included templates is Sharp Architecture; Advanced model validations: it even warns you about having lazy properties declared in non-lazy entities; Integration with NHibernate Validator and generation of validation rules automatically based on the database, or on user-defined model settings; The designer: they opted for not displaying all entities in a single screen, which I think was a good decision; has support for all inheritance strategies (table per class hierarchy, table per class, table per concrete class); Generation of FluentNHibernate mappings as well as hbm.xml. I could name others, but… why don’t you see for yourself? There is a demo version available for downloading. By the way, I am in no way related to Slyce, I just happen to like their software!

  • strange behavior in Box2D+LibGDX when applying impulse

    - by Z0lenDer
    I have been playing around with Box2D and LibGDX and have been using a sample code from DecisionTreeGames as the testing ground. Now I have a screen with four walls and a rectangle shape, lets call it a brick. When I use applyLinearImpulse to the brick, it starts bouncing right and left without any pattern and won't stop! I tried adding friction and increasing the density, but the behavior still remains the same. Here are some of the code that might be useful: method for applying the impulse: center = brick.getWorldCenter(); brick.applyLinearImpulse(20, 0, center.x, center.y); Defining the brick: brick_bodyDef.type = BodyType.DynamicBody; brick_bodyDef.position.set(pos); // brick is initially on the ground brick_bodyDef.angle = 0; brick_body = world.createBody(brick_bodyDef); brick_body.setBullet(true); brick_bodyShape.setAsBox(w,h); brick_fixtureDef.density = 0.9f; brick_fixtureDef.restitution = 1; brick_fixtureDef.shape = brick_bodyShape; brick_fixtureDef.friction=1; brick_body.createFixture(fixtureDef); Walls are defined the same only their bullet value is set to false I would really appreciate it if you could help me have a change this code to have a realistic behavior (i.e. when I apply impulse to the brick it should trip a few times and then stop completely).

  • Ubuntu 12.10 ATI Driver 12.11 fails after compiz and xorg update

    - by Lukasz W.
    I updated my system via the package manager from Unity and next restart was just blackness. After being here: http://linux.hootip.com/amd-catalyst-12-11-beta-fix-and-installation-the-drivers-on-ubuntu-12-11/ I had the Catalyst 12.11 Beta driver installed. I checked my /var/log/apt/history.log and the update I received was of compiz and xorg packages. I tried to get latest release info, but all I get from their pages are commit info; I can't tell what was n the package update I got served. Anyone knows what was in the latest xorg/compiz release that broke the driver? Which driver should I use now? For completeness this is how I got the system back to boot (probably lame and not elegant): Boot with GRUB selection "More Ubuntu options (or sth like that), From secondary screen select 3.5.0-19 with boot options, When system prompts on stuff you'd like to do, select "root" - Drop to root shell, There: # mount -o remount,rw / # mv /etc/X11/xorg.conf /etc/X11/xorg.conf.failed # /usr/share/ati/fglrx-uninstall.sh # reboot This got be back on my feet.

  • How do I get back hard drive space after I have uninstalled Ubuntu from Windows?

    - by Shantanu
    I installed Ubuntu on windows like it says to do it on Ubuntu's website as an application. I did not want it to create a separate partition on my hard drive. A few days ago, I uninstalled Ubuntu by going into the Windows control panel and hitting uninstall. As you would expect, I would get back my 100 or so gb on the disc. i never really installed anything of importance on ubuntu so i never had a second thought about uninstalling it. But I never got back my 100gb from Ubuntu. Now when I add up all of the folders on my c drive, they total to the amount I had on windows before I uninstalled Ubuntu but when I look at the My Computer screen, it says that another 100 or so gb is missing. I tried defragmenting the disc, downloading various disc managers but nothing fixed the space problem. Can anyone please help me with this!!??? Any help is much appreciated! Just making sure: UBUNTU WAS NOT ON A SEPARATE PARTITION, IT WAS INSTALLED AS AN APPLICATION ON WINDOWS. It tells yuo how to do this here except i did it with a much older version (i think it was 8.04 or soemthing): http://www.ubuntu.com/download/help/install-ubuntu-with-windows

  • HP LaserJet Pro 400 Color M451dn Phantom Print Jobs

    - by francisswest
    Scenario: Multiple printers hooked up to a printer server (2008r2) including this HP LaserJet Pro 400 Color M451dn. All machines that are using the printer are based on Windows 7 Enterprise x64. Problem: Every couple of days the users who frequent this printer let me know that a few dozen pages with random characters down one side of the paper print out. This happens usually during the evening when no one is around to send print jobs to it. What I have done: Provided the below screen shot of the printer log with what I assume is the print jobs in question. I have looked into the printer driver compatibility and found no issues. Question: Is there a known issue with this printer or similar printers, and is there a solution that people are familiar with when they see multiple pages of gibberish printing out?

  • The mouse pointer in my Ubuntu VM has turned into a little hand with a document, and clicks are igno

    - by Daryl Spitzer
    The mouse pointer in my Ubuntu 8.04.3 LTS VM (running in VMware Fusion) has changed into a little hand holding a document. It doesn't show up in screen-shots. All mouse clicks (left or right) are ignored. But I can still type in the one Terminal window I have open. (And commands work fine.) I wonder if I'm in some kind of drag-and-drop mode. How do I get out of this? Update: Rebooting (from the command-line) worked. Ubuntu came up with the regular mouse-pointer.

  • No virtual console on ubuntu 12.10

    When I try to do a ctr-alt f(1-6) in ubuntu 12.10 I only get a black screen with a blinking cursor but no login prompt. Any ideas on what could be wrong?

  • Physically moving a hard drive from older iMac (c2d) to new iMac (i7) ?

    - by Inshim
    Instead of my usual habit of using superduper to mirror my drive to a new computer, I just physically moved the hard drive from an older iMac to a new one. But... it now doesn't boot, getting stuck at the apple logo screen. Since the hard drive that came with the new iMac works well, and my old drive works well when I return it to the older iMac, I conclude that there is some problem at the system/kernel level due to the different hardware. In the past I did similar things (e.g. starting a C2D machine from a Core Duo in target disk mode), so perhaps the change in architecture to the i5/i7 is too problematic? The main point: do you know of any way to get the system to rebuild for itself the proper versions of the system components when booting? Are there certain directories that I can safely delete to make that happen? Thanks

  • Why do I get "General Failure" when pinging host name on a Win 7 node on the network?

    - by hydroparadise
    This is a very peculiar problem with a station on our network. The client pc is running Windows 7 Pro. What makes this problem interesting is that this client is the only node on the network that seems to be experiencing this proglem. When I try to ping a specific Win 08 server by host name, I get an IPv6 address and get General failure. But when I ping it's IPv4 address, it responds just fine. My first thought would check the DNS server the name resolutions to see what would be going on, but the problem begs the quesion, why does the station get an IPv6 address back and fails as opposed to using the IPv4 settings (which are static btw). What gives? I am including a screen shot of trying the one specific server and failing while trying another server with success. All other nodes on the network don't have problems communicating with the server the one station is having issues with.

  • Simple collision detection for pong

    - by Dave Voyles
    I'm making a simple pong game, and things are great so far, but I have an odd bug which causes my ball (well, it's a box really) to get stuck on occasion when detecting collision against the ceiling or floor. It looks as though it is trying to update too frequently to get out of the collision check. Basically the box slides against the top or bottom of the screen from one paddle to the other, and quickly bounces on and off the wall while doing so, but only bounces a few pixels from the wall. What can I do to avoid this problem? It seems to occur at random. Below is my collision detection for the wall, as well as my update method for the ball. public void UpdatePosition() { size.X = (int)position.X; size.Y = (int)position.Y; position.X += speed * (float)Math.Cos(direction); position.Y += speed * (float)Math.Sin(direction); CheckWallHit(); } // Checks for collision with the ceiling or floor. // 2*Math.pi = 360 degrees // TODO: Change collision so that ball bounces from wall after getting caught private void CheckWallHit() { while (direction > 2 * Math.PI) { direction -= 2 * Math.PI; } while (direction < 0) { direction += 2 * Math.PI; } if (position.Y <= 0 || (position.Y > resetPos.Y * 2 - size.Height)) { direction = 2 * Math.PI - direction; } }

  • SharePoint 2010 Single Page Apps without a Master Page

    - by David Jacobus
    Originally posted on: http://geekswithblogs.net/djacobus/archive/2014/06/06/156827.aspxWell, maybe a stretch, but I am inclined to believe it is so.  I have been using  the JavaScript Client Object Model (JCSOM) for about 6 months now and I believe it can do about 80% of my job quickly without much fanfare.  When building sites in SharePoint no one wants the OOTB list views, etc. They want a custom look and feel!  I used to think in previous engagements that this would mean some custom server code or at least a data-form web part.   Since coming on-board in my current engagement, I have been forced because we don’t own the hosting site to come up with innovative ways to customize the UI of SharePoint.  We can push content via sandbox solutions and use JCSOM from within SharePoint Designer to do almost all customizations.  I have been using the following methodology to accomplish this: 1. Create an HTML file, which links CSS and JavaScript Files 2. Create and ASPX Web Part Page, Include a Content Editor Web Part and link to the HTML page created above.   So basically once it was done, I could copy , paste,  and rename those 4 items: CC, JS, HTML. ASPX and using MVVM just change the Model, View, and View-Model in the JavaScript file.  in about 5 minutes, I could create a completely new web part with SharePoint data.  Styling would take a little longer.  Some issues that would crop up: 1.  Multiple(s) of these web parts would not work well together on the same page (context). 2.  To separate the Web parts and context I would create a separate page for each web part and link them to a tabs layout via a Page Viewer web part or I frame.  Easy to do and not a problem but a big load problem as these web part pages even with minimal master had huge footprints.  (master page and page web part zones)   I kept thinking of my experience with SharePoint 2013 and apps!  The JavaScript was loaded from within the app, why can’t we do that in 2010 and skip the master page and web part zones. I thought at first, just link to sp.js but that didn’t work so I searched the web and found a link which did not work at all in my environment but helped me create a solution that would kudos to (Will). <!DOCTYPE html> <%@ Page %> <%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Import Namespace="Microsoft.SharePoint" %> <html> <head> <link rel="Stylesheet" type="text/css" href="../CSS/smoothness/jquery-ui-1.10.4.custom.min.css"> </head> <body > <form runat="server"> <!-- the following 5 js files are required to use CSOM --> <script src="/_layouts/1033/init.js" type="text/javascript" ></script> <script src="/_layouts/MicrosoftAjax.js" type="text/javascript" ></script> <script src="/_layouts/sp.core.js" type="text/javascript" ></script> <script src="/_layouts/sp.runtime.js" type="text/javascript" ></script> <script src="/_layouts/sp.js" type="text/javascript" ></script> <!-- include your app code --> <script src="../scripts/jquery-1.9.1.js" type="text/javascript" ></script> <script src="../Scripts/jquery-ui-1.10.3.custom.min.js" type="text/javascript"></script> <script src="../scripts/App.js" type="text/javascript" ></script> <div ID="Wrapper"> </div> <SharePoint:FormDigest ID="FormDigest1" runat="server"></SharePoint:FormDigest> </form> </body> </html> Notice that I have the scripts loaded within the body!

  • How to suppress or disable the shutdown option from indicator menu or shutdown dialog?

    - by user73093
    My goal is to allow user only to restart the system, and deny any shutdown (suspend, hibernate). I am running unity-2d. I 've managed to deny suspend and hibernate with polkit policy files like explained in How to disable shutdown/reboot/suspend/hibernate? I observed that is has somehow disable shutdown abilities, but hasn't removed "shutdown" entry from the indicator panel menu neither as well as the "shutdown..." button from the shutdown dialog. Pressing shutdown button at this point restarts lightdm, returning to the login screen. My goal is to remove any "shutdown" action and button. So, I 've added an ovveride file in /usr/share/glib-2.0/schemas that contains some rules: [com.canonical.indicator.session] suppress-shutdown-menuitem = true (all suppress-*-menuitem has "false" value by default in the schema) Compiling, restarting X, now there is an entry "close session..." in the indicator panel menu...: it's not what I want. at this point, if I set another entry suppress-logout-menuitem to true I got no entry in the indicator panel menu. Trying like this all combination doesn't give the opportunity to remove "shutdown" references/buttons without removing restart option. All I want is to remove any reference to "shutdown" but keep a "restart" option somewhere in the indicator menu... Thanks !

  • Computer is really slow

    - by joshhunt
    I'm not exactly sure when exactly it started happening, but my computer now is extremely slow. Originally, I have been using this computer for all sorts of stuff: Photoshop, web design/development, movies and even some light (Warcraft 3) gaming. I have been running it with Windows XP But now it is very, very slow, and I don't know how, why or when this happened. After I noticed the slowness, I removed Windows XP and installed Windows 7 on it, but it is still very slow. Now watching videos is unbearable at full screen (slow frame rates, audio out of sync) and painful when made smaller. Why would this happen? What would cause this? I am starting to think it is a hardware problem (the CPU has died or something), but I don't even know if that is possible. The PC is running with 1GB of RAM, three hard drives (all up, something like 400 GB) and I think a 1.6GHz processor

    - by Matthew
    My computer has been crashing the last couple weeks pretty regularly (at least once a day). A lot of times things I do will display a little notification in the bottom right saying something about a corrupt file. (I'm on Windows XP Pro Service Pack 3). When the computer does crash I get the "blue screen of death" usually. Some of the notifications also advise running the chkdsk utility. I cannot get it to successfully run. Using the command prompt (or even the "tools" menu after right clicking the drive and choosing properties), it will not run the utility (it says "do you want to schedule it to run next boot time" or whatever, which I confirm). The problem is that most of the time after restarting, it doesn't run at all. The few times it does run, it has an error (I can't remember the error right now, it at least says it's ntfs and such) and says disk checking will end. How can I get it to successfully run?

  • Game programming basics under Windows

    - by dreta
    I've been trying to learn some Windows programming using the Win32 API. Now, i'm used to working with the OS layer being abstracted away, mostly thanks to libraries like SFML or Allegro. Could you guys help me out and tell me if i'm thinking right here. The place for my gameloop is where i'm reading the messages? while (TRUE) { if (PeekMessage (&msg, NULL, 0, 0, PM_REMOVE)) { if (msg.message == WM_QUIT) break ; TranslateMessage (&msg) ; DispatchMessage (&msg) ; } else { //my game loop goes here } } Now the slightly bigger issue, that is, drawing. Do i run my drawing where i normaly do it, inside the game loop after the game logic? Or do i do it when WM_PAIN is being called and just call InvalidateRect (hwnd, NULL, TRUE); when i want to draw? This does feel weird, the WM_PAINT is a queued message, so i don't know for sure when it'll be called. So if i wanted to avoid this, do i just get the device handle inside the game loop and only ValidateRect (hwnd, NULL); in the WM_PAINT case (beside the ValidateRect (hwnd, NULL); called after drawing in the game loop)? Actually, now that i think about it, do i even need WM_PAINT in this situation or can i skip it and let DefWindowProc handle it (does it validate the screen if WM_PAINT isn't processed)? If this is any important, i'm setting up my code for OpenGL.

  • GLSL billboard move center of rotation

    - by Jacob Kofoed
    I have successfully set up a billboard shader that works, it can take in a quad and rotate it so it always points toward the screen. I am using this vertex-shader: void main(){ vec4 tmpPos = (MVP * bufferMatrix * vec4(0.0, 0.0, 0.0, 1.0)) + (MV * vec4( vertexPosition.x * 1.0 * bufferMatrix[0][0], vertexPosition.y * 1.0 * bufferMatrix[1][1], vertexPosition.z * 1.0 * bufferMatrix[2][2], 0.0) ); UV = UVOffset + vertexUV * UVScale; gl_Position = tmpPos; BufferMatrix is the model-matrix, it is an attribute to support Instance-drawing. The problem is best explained through pictures: This is the start position of the camera: And this is the position, looking in from 45 degree to the right: Obviously, as each character is it's own quad, the shader rotates each one around their own center towards the camera. What I in fact want is for them to rotate around a shared center, how would I do this? What I have been trying to do this far is: mat4 translation = mat4(1.0); translation = glm::translate(translation, vec3(pos)*1.f * 2.f); translation = glm::scale(translation, vec3(scale, 1.f)); translation = glm::translate(translation, vec3(anchorPoint - pos) / vec3(scale, 1.f)); Where the translation is the bufferMatrix sent to the shader. What I am trying to do is offset the center, but this might not be possible with a single matrix..? I am interested in a solution that doesn't require CPU calculations each frame, but rather set it up once and then let the shader do the billboard rotation. I realize there's many different solutions, like merging all the quads together, but I would first like to know if the approach with offsetting the center is possible. If it all seems a bit confusing, it's because I'm a little confused myself.

  • A* Start path finding in HTML5 Canvas

    - by gyhgowvi
    I'm trying implement A* Start path finding in my games(which are written with JavaScript, HTML5 Canvas). Library for A* Start found this - http://46dogs.blogspot.com/2009/10/star-pathroute-finding-javascript-code.html and now I'm using this library for path finding. And with this library, I'm trying write a simple test, but stuck with one problem. I'm now done when in HTML5 canvas screen click with mouse show path until my mouse.x and mouse.y. Here is a screenshot - http://oi46.tinypic.com/14qxrl.jpg (Pink square: Player, Orange squares: path until my mouse.x/mouse.y) Code how I'm drawing the orange squares until my mouse.x/mouse.y is: 'http://pastebin.com/bfq74ybc (Sorry I do not understand how upload code in my post) My problem is I do not understand how to move my player until path goal. I've tried: 'http://pastebin.com/nVW3mhUM But with this code my player is not beung drawn.(When I run the code, player.x and player.y are equals to 0 and when I click with the mouse I get the path player blink and disappear) Maybe anyone know how to solve this problem? And I'm very very very sorry for my bad English language. :)

  • After repairing permissions, Mac OS X won't boot

    - by Power-coder
    This morning I ran the Repair Permissions command from inside the Disk Utility. Ever since then my MacBook wont move past the splash screen when booting. I've revolted in verbose mode and I see that it is trying to repair the disk but then terminates with 'Unable to repair the volume'. Since then I have tried running the Disk Repair from the Snow Leopard install DVD and it quits with the same error. Is there a way I can repair this thing without reformatting and installing over again? How does something so simple as a permissions repair make the system unbootable like this?

  • System in low-graphics mode

    - by Artem Moskalev
    I am totally new to Linux, and Ubuntu. I bought ASUS X53E Notebook, erased Windows and installed Ubuntu. First it worked ok. Then when I started working with it, i opened the terminal, entered sudo chmod 666 usr and then all the icons from the main panel disappeared + the whole system stopped responding. I decided to restart the system. When restarted, a message appears: the system is running in low graphics mode and below it: Your screen, graphics card and input device setting could not be detected correctly. You will need to configure it yourself. But the "OK" button is disabled and if I press any buttons nothing happens. If I enter Ctrl-Alt-F2 it opens the bash terminal. But there commands sudo or apt-get are not found and it says that permission denied if i try to enter any folder like cd /usr If I enter the su command it asks for the password I don't know. When encountering this problem first, I reinstalled the whole Ubuntu. but today it happened again just the same. What shall I do? maybe there is something wrong with the hardware? If I need to install another distribution of Linux could you recommend one? but I'd rather stick to Debian releases like Ubuntu. so how do I fix the problem? PS: Please give answers in simple terms because am a newbie so i don't know what goes where yet.

  • Ubuntu stops using Nvidia driver after kernel upgrade

    - by Daniel
    Just updated and restarted, Ubuntu's doesn't display correctly. After restart, the desktop now looks like this. I've temporarily switched to the Nouveau driver. The update history reveals the kernel was updated, amongst many things; and the following were installed: linux-image-3.5.0-19-generic (3.5.0-19.30) linux-image-extra-3.5.0-19-generic (3.5.0-19.30) I've encountered this type of problem quite recently, so I decided to reapply the same steps, to solve the problem, as follows: sudo apt-get install linux-headers-3.5.0-19 sudo apt-get install linux-headers-3.5.0-19-generic sudo depmod -a sudo modprobe nvidia sudo /etc/init.d/*dm restart When installing linux-headers-3.5.0-19-generic, I get an error, message from terminal as follows: Setting up linux-headers-3.5.0-19-generic (3.5.0-19.30) ... Examining /etc/kernel/header_postinst.d. run-parts: executing /etc/kernel/header_postinst.d/dkms 3.5.0-19-generic /boot/vmlinuz-3.5.0-19-generic Error! Problems with depmod detected. Automatically uninstalling this module. DKMS: Install Failed (depmod problems). Module rolled back to built state. However, I ignored the above error and continued the steps with sudo depmod -a, installed nvidia-current, then did sudo modprobe nvidia, which yielded the following error: FATAL: Error inserting nvidia_current (/lib/modules/3.5.0-19-generic/updates/dkms/nvidia_current.ko): No such device Upon restart, the Nvidia driver now works! BTW, do those error messages imply I broke something? Just curious, cause I don't want to get happy I've fixed it, then it stops working later on. The system is Dell XPS-L702X, with NVIDIA GeForce GT 555M, and 17" screen.
