• Dual Screens not working nVidia

  - by user91396

  So I'm very much an Ubuntu noob, in fact I just install Ubuntu to my P.C. and I started it up with both my screens plugged into my nVidia's dvi and vga ports and logged in, change the skin to classic gnome, because that's how it was when I last used Ubuntu (8.1), and both screens were working separately. The trouble is that I got a notification saying there was nVidia drivers to be installed, so I install them and restart my P.C., as it told me to, and when I get back on only one of my screens is working and when I go into Displays (All Settings, Displays) it doesn't register my other screen at all, and it calls my working screen "Laptop". I've tried looking through several pages of Google but I see no answer. I did try to find the nvidia-settings to see if that had the answers but sadly I couldn't locate it. Thanks in advance for any help, but please remember, I am very new to Ubuntu.

• Is my motherboard failing, or is there some other issue?

  - by ThatGuy

  So, several months ago I put together my own desktop PC. I set up a dual boot to Windows and Ubuntu. Recently, without changing any settings or installing anything new, the wifi stopped working on windows (I use a wifi adapter). It said it was connected, Network settings showed that it was working and running trouble shooting had no results. My internet still works on any other device. I found that removing the adapter from the motherboard and plugging it back in was the only thing that fixed the problem. Reinstalling the wifi drivers did not help. I purchased a new Wifi adapter, but the problem persists. More recently, I had a much more discouraging development. Sometimes, turning on the computer results in a boot loop: BIOS never starts. Instead, the monitor turns on as if it got a signal, then immediately turns off. This loops on it's own indefinitely until I hold down power, hard reset it, and try again. Sometimes it works, sometimes it doesn't. I haven't tested much on the Ubuntu side. It appears that wifi works at least some of the time, but since I've had issues just getting to BIOS I'm not confident the issue is on the software side. I've also noticed issues with some of the USB ports no longer working, but that seems to be off and on. Finally, as of a few minutes ago, I booted to windows to discover that everything was running very slowly. Slow here is a relative word, but I have a Samsung 840 pro SSD and I'm used to applications running nigh instantly, and it was a solid 3 minutes before any of my applications would load. Anyway, my question is this: Is it likely that my motherboard is failing? Either way, what steps can I take to try and pin down the problem and figure out what to do?

• How can I compute the Big-O notation for a given piece of code?

  - by TheNew Rob Mullins

  So I just took a data structure midterm today and I was asked to determine the run time, in Big O notation, of the following nested loop: for (int i = 0; i < n-1; i++) { for(int j = 0; j < i; j++2) { //1 Statement } } I'm having trouble understanding the formula behind determining the run time. I thought that since the inner loop has 1 statement, and using the series equation of: (n * (n - 1)) / 2, I figured it to be: 1n * (n-1) / 2. Thus equaling (n^2 - 1) / 2. And so I generalized the runtime to be O(n^2 / 2). I'm not sure this is right though haha, was I supposed to divide my answer again by 2 since j is being upped in intervals of 2? Or is my answer completely off?

• Drawing Transparency in XNA 4.0

  - by dpaz

  Using C# (VS2010) with XNA 4.0, I have a terrain layer (RenderTarget2D) in a 2D side-scroller. My visual system tracks updates to redraw individual tiles, but I am having trouble finding a way to clear out the rectangle where the tile will be drawn, which I must do because A) there may no longer be a tile or B) the tile may itself contain transparency. How can I draw a rectangle of transparency onto an existing RenderTarget2D? I essentially want to clear just that rectangular portion of it. My Google searches have not yielded anything relevant.

• How to install ubuntu 12.04

  - by William A. Jordan

  I've had ubuntu on my pc for about 5 years,after the new 12.04 version and a day and a half trying to get it to just boot up. I will take it off my pc and rely on windows. I have 5 pc's which I built and am not an amateur, After installing it numerous times and even to run it from your webpage (to no avail). Granted I do have nvidia drivers on it, but after I went to their webpage and downloaded and installed the linux driver it,it still would not boot, by the way I took 2 different pc's apart and used what I thought were compatible (I shouldn't have to do this) parts. I have it on a seperate hd which I will remove and format. Have a nice day and so long (2 much trouble).

• Svchost.exe connecting to different IPs with remote port 445

  - by Coll911

  Im using Windows XP Professional SP2. Whenever I start my Windows, svchost.exe starts connecting to all the possible IPs on LAN like from 192.168.1.2 to 192.168.1.200. The local port ranges from 1000-1099 and the remote port being 445. After it's done with the local IPs, it starts connecting to other random IPs. I tried blocking connections to the port 445 using the local security polices but it didn't work. Is there any possible way I could prevent svchost from connecting to these IPs without involving any firewall installed? My PC slows down due to the load. I scanned my PC with MalwareBytes and found out it was infected with a worm, it's deleted now but still svchost is connecting to the IPs. I also found out that in my Windows Firewall settings, under Internet Control Message Protocol (ICMP), there's a tick on "allow incoming echo request" (usually disabled) which is locked and I can't disable it. Its description is as follows Messages sent to this computer will be repeated back to the sender. This is used for trouble shooting for e.g to ping a machine. Requests of this type are automatically allowed if TCP port 445 is enabled. Any solutions? I can't bear going with the reinstalling Windows phase again.

• 20 1TB drives vs. 10 2TB drives in RAID5/6 server

  - by Hunter

  Hi everyone, I will be setting up a server at work and I need some advice on some details. The setup will be one blade-type server (8-core, 16GB RAM) with two subsystems - one for the main storage the other to back it up. I'm shooting for a 20TB array (I know it'll be less after formatting and parity drives). So is there any advantage one way or the other with either 20 1TB drives or 10 2TB drives? I'm not sure right now how many controllers I should have either (in the quote I have is a dual-port controller). I would think two controllers for a server of this size would be a better choice than the dual-port controller (but I really don't know). And would an array of this size have any performance issues in RAID 5 or 6 (I know RAID 5 or 6 are "slower" because of all the parity calculations). Also, these will be either WD RE3 (1TB) or the RE4 (2TB). Oh, also, for the backup array would it be ok to use the WD 2TB green drives (also in RAID5 or 6)?

• A peculiar issue with nm-applet

  - by montreux

  There is a somewhat strange error that I've noticed with my gnome sessions. It's not a problem that causes a lot of trouble, but at times it becomes annoying. Anyway, here it is: when I fire up gnome-session-fallback (which is the main one I use), the network applet doesn't run with root permission. Here is what it looks like http://i.imgur.com/8kc7Vrd.jpg . On the other hand, here is what the regular gnome session looks like http://i.imgur.com/wfkkE3E.jpg . From the regular session I can easy edit and add networks, but from fallback session I cannot add/edit anything, or turn off/on the wireless or networking. Any ideas?

• I Can't install Skype on Ubuntu 12.04 x64. Can someone help me?

  - by Matheus

  I'm having a trouble when trying to install Skype on my Ubuntu 12.04.1 x64. My notebook have compatible hardware with Ubuntu. My previous OS installed on this machine was the Ubuntu 12.04 x64 and Skype was working great, but I got a formatation and I installed the New ubuntu 12.04.1. When I try to install by the Ubuntu software Center, or by the sudo apt-get install skype, I get this error message (in Portuguese) : "Os pacotes a seguir têm dependências desencontradas: skype: Depend: skype-bin E: impossivel corrigir problemas, você manteve (hold) pacotes quebrados." Something like i have the skype-bin package missing (or broken). I can't find it on Software center. I tried to install it by downloading a deb package with the skype-bin package but it ask for a lot another packages! I tried install the .deb package from the official Skype site, but I got the same error! Any Help? Sorry about my bad English, I'm Brazilian

• GUI won't load, but the desktop background loads. Can't access the terminal

  - by Mickeysofine

  Having trouble with the Ubuntu GUI. I can log in just fine (see this)... everything looks normal there. But as soon as I put in my password, I get this. I tried a few different troubleshooting keyboard commands (ctrl+alt+t, crtl+alt+delete), and only the latter worked. I can interact with that window just fine, except I am unable to resize or move it. The first time I logged in, I got a dialog box that said, "Ubuntu has experienced an internal error. Send error report?" Doesn't say anything now. Yes I tried restarting it. Thanks a bunch, Michael EDIT: Trying to start a guest session leads to the same problem.

• How to draw a texture to a MS Terrain object - Farseer

  - by Brad

  I'm using Farseer to make a game in XNA and I can't seem to figure this out. I've decided to use MSTerrain for making my game's terrain because I wanted destructible terrain and MSTerrain seemed like the best bet. Unfortunately, I'm stumped on how to actually show the terrain. When I generate the terrain it's visible in debug view, but MSTerrain does not have a Draw method, so I'm wondering how it is supposed to be drawn to the screen? Is it worth pursuing? I'm starting to think that MSTerrain is more trouble than it's worth, is there another better way to do this with bodies? I appreciate any help you can give. Thanks.

• URL subfolder rewrite without server access

  - by Duke03

  I am having trouble with the following. I have a site in development that has every link on the site pointing to the wrong folder. Example: example.com/en/home/, a site link goes to example.com/en/, which throws a 404. Now the way the system is setup requires server access but I do not have that and I/S is backlogged with requests and will take a week. But I still need to develop the site. So is there a way to have the browser recognize when example.com/en/ is clicked then automatically redirect it to example.com/en/home so it bypasses the 404 and I can actually work. Im looking for anything that gets the job done. I am considering developing a Chrome app to do this but that would mean a shit ton of overtime and more work I don't want to do. Is there a easier way of doing this?

• Pygame - CollideRect - But How Do They Collide?

  - by Chakotay

  I'm having some trouble figuring out how I can handle collisions that are specifically colliding on the top or bottom a rect. How can specify those collisions? Here's a little code snippet to give you an idea of my approach. As it is now it doesn't matter where it collides. # the ball has hit one of the paddles. send it back in another direction. if paddleRect.colliderect(ballRect) or paddle2Rect.colliderect(ballRect): ballHitPaddle.play() if directionOfBall == 'upleft': directionOfBall = 'upright' elif directionOfBall == 'upright': directionOfBall = 'upleft' elif directionOfBall == 'downleft': directionOfBall = 'downright' elif directionOfBall == 'downright': directionOfBall = 'downleft' Thanks in advance. **EDIT** Paddle rect: top ____ | | | | | | Sides | | ---- bottom I need to know if the ball has hit either the top or the bottom.

• Should an image be able to resize itself in OOP?

  - by ChocoDeveloper

  I'm writing an app that will have an Image entity, and I'm already having trouble deciding whose responsibility each task should be. First I have the Image class. It has a path, width, and other attributes. Then I created an ImageRepository class, for retrieving images with a single and tested method, eg: findAllImagesWithoutThumbnail(). But now I also need to be able to createThumbnail(). Who should deal with that? I was thinking about having an ImageManager class, which would be an app-specific class (there would also be a third party image manipulation reusable component of choice, I'm not reinventing the wheel). Or maybe it would be 0K to let the Image resize itself? Or let the ImageRepository and ImageManager be the same class? What do you think?

• No sound/audio after resuming from sleep

  - by hansvonaachen

  I've made a fresh UEFI install of Ubuntu 13.10 (64 bit) on a Lenovo Ideapad Z510 laptop with Intel i5 4200M processor. Ubuntu is the only OS installed on the computer, secure boot disabled. Everythings works fine (backlight issue fixed after editing rc.local file), the only minor trouble I have is resuming the laptop from "sleep" mode. If I close the lid and then wake the laptop opening it again, there is no audio/sound. I need to restart the computer (not even logging out helps). If I suspend the computer in a graphical way (not closing the lid): gearwheel in top right of the screen -- suspend and wake it up/turning on, audio works with no issues. Ideas how to fix this? Thanks!

• What is the most secure environment for multiple CMS sites? [closed]

  - by Brian Gulino

  I wish to run about 50 Joomla or WordPress low-traffic websites on 1 server, or part of a server. Each website will be managed by its own, naive owner who will have be able to access the Joomla or Wordpress backend of the website. I am concerned about security and isolation as my users will periodically get into trouble by not protecting their sites properly. Two alternatives I know of exist: Run one Linux system with multiple websites under Apache. Follow current Joomla and WordPress security tips. Increase the isolation of the individual sites by using mpm-itk, which will allow each website to run as its own user. The alternative to this is to run virtualization software such as the Xen hypervisor. Each site would have its own, virtual Linux system. I lack the experience needed to make this decision and I am asking which path to take. Obviously, there may be other alternatives that I haven't considered.

• See how one goal leads to another (i.e., how often downloading the demo leads to purchasing)

  - by s3cur3

  I have two goals set up for my site in Google Analytics: one to download the demo of my software, and the other to buy the full version. I'm having trouble getting statistics on how often the download leads to a purchase. This seems like something the multi-channel funnel is perfect for (as in this question)---I expect that it takes multiple visits for the demo download to convert into an order. However, I can't seem to narrow down the multi-channel funnel data into only those that have one goal followed by another. If it matters, I'm tracking the ordering action as a page view (i.e., someone views the "Thanks for ordering" page) and the demo download as an action (which fires when someone clicks the "download" button). Thanks! - Tyler

• Why creating a new MDX language instead of extending SQL?

  - by DReispt

  I have a long experience with SQL, but recently began working with datawarehouse and OLAP technologies: building fact and dimension tables, that then are queried using MDX (MultiDimensional eXpressions). The problem is that MDX works with a completely different logic compared to SQL, and it's a whole new learning curve even for someone with a strong SQL background. Yes, MDX allows you to do things that would be hard or almost impossible with plain SQL. But sometimes it's frustrating to be hours around an MDX to do something you know you could achieve in minutes using SQL (ok, you can tell me to RTFM ...). But why go on to the trouble of creating a new completely different language when you could build on SQL, extend it to add the features needed by OLAP applications?

• Algorithm to generate N random numbers between A and B which sum up to X

  - by Shaamaan

  This problem seemed like something which should be solvable with but a few lines of code. Unfortunately, once I actually started to write the thing, I've realized it's not as simple as it sounds. What I need is a set of X random numbers, each of which is between A and B and they all add up to X. The exact variables for the problem I'm facing seem to be even simpler: I need 5 numbers, between -1 and 1 (note: these are decimal numbers), which add up to 1. My initial "few lines of code, should be easy" approach was to randomize 4 numbers between -1 and 1 (which is simple enough), and then make the last one 1-(sum of previous numbers). This quickly proved wrong, as the last number could just as well be larger than 1 or smaller than -1. What would be the best way to approach this problem? PS. Just for reference: I'm using C#, but I don't think it matters. I'm actually having trouble creating a good enough solution for the problem in my head.

• How do I get a Realtek Wireless USB Airlink101 AWLL5088 working?

  - by Tobias_Mann

  I am running Ubuntu 11.10, 32bit. I ordered them a Realtek Airlink101 AWLL5088 based upon the relative ease for linux installation. I am having trouble installing the drivers. I copied the drivers to /usr/src/ and ran sudo ./install.sh from that director listed above. I have tried ndiswrapper, and allowing the default drivers, but with no luck. It seems to continue to try and use the default free drivers, even though I have blacklisted them using the guide described here. There was no error, I was asked which card I was using. I looked at the packaging and at the support page, and guessed number 2, allowed to finish, and rebooted. It continued detect the wireless network after the reboot, but would never complete the connection. I would appreciate any feedback. I am kind of stuck trying to figure this out.

• After installing ubuntu, all my partitions are gone. Boot-repair log

  - by user211079

  I have an HP Pavilion Sleekbook that came with windows 8 pre-installed. I had trouble dual booting after installing ubuntu, so I disabled safeboot on bios and proceeded to try boot-repair, nothing happened. No dual boot yet. So I tried to reinstall ubuntu, but without the manual partitioning. So I chose to erase ubuntu 13 and reinstall it. Instead it deleted all my HP recovery partitions and windows as well. Here is the log of boot-repair. http://paste.ubuntu.com/6354919/ Gparted and fdisk only show one partition: /dev/sda1 I am wondering if you could suggest any way of recovering my windows partition and have a working windows 8 again? I need some information there with urgency. If you could help me I will be welcome. I am desperated. Thanks

• Can't cancel the lubuntu shutdown screen

  - by user292040

  I've bought a small 5 year old small netbook. I noticed that lubuntu runs great on it, as it doesn't use much space/resources. But the problem is, my screen is just too small. Whenever I press the shutdown icon, I go to the shutdown, logout, restart, ect panel but the cancel button is tucked away right where my screen seems to end. I can't go back, it forces me to use an option besides canceling, which I can't reach with my mouse.Is there any way to change this so I get access to the whole screen. The rest seems to be showing just fine, like the launchbar, which is cleary visible and useable. Another thing that bugs me is that whenever I start up, I get an error along the lines of "conflict detected with stolen region". I read that it has something to do with graphics but I have no idea how to get rid of it. The error doesn't seems to cause any trouble as far as I can see, but it's annoying.
