• Asking about deleted partition at boot

  - by Shawn Mitchell

  I have Ubuntu installed through Wubi. I also had another partition on my computer to try out the dev preview of Windows 8 aptly named Windows_8. After I was done playing, I deleted the Windows 8 partition and added the extra space back to my Win7/Wubi partition. Now every time I boot into Ubuntu, it tells me that it can't mount the partition and asks me if I want to recover or skip it. Is there a way to get Ubuntu to forget about this partition so I can skip this extra step in my boot? Thanks

• How to advance in my JavaScript skills? [closed]

  - by IlyaD

  I am using javascript for about two years now, and I feel that I can do really basic stuff. I can make some basic algorithms and mostly use jQuery for interactive elements on webpages, and as I need to do more advanced things I get the feeling that my knowledge is lacking. In most cases I find a code, it takes me quite some time to understand it, but I don't understand why it is written as it is. I have no background in computer science, so I'm not sure weather I should go to the basics, or get some advanced javascript book/course. How can I make that jump from using JS for scripting to become a real programmer?

• First time using Ubuntu, need help with drivers!

  - by Nick

  I have just successfully built my first computer last night. I went through the boot menu and got Ubuntu 12.10 installed properly and everything. My question is...now what? There has to be some sort of drivers I need to install right? I can't connect to wi-fi or anything of that sort. I have an ASUS motherboard, model number M4N98TD EVO , and an NVIDIA Geforce GTX 650 grpahics card. I guess my main question is, can someone run me through step by step what I need to do after I install Ubuntu?

• How to protect own software from copying [closed]

  - by Zzz

  Possible Duplicate: How do you prevent the piracy of your software? Is possible to protect some file from copying if you are administrator of machine? I heard some story about some behavior: one software developer sells his software in some way. He is installing it on every client's computer and this software does not work on other computers or cannot be copied physically. How to implement the first and second protection. Is it effectively protection if software costs about $100 for all copies across client's company?

• How does the "Fourth Dimension" work with arrays?

  - by Questionmark

  Abstract: So, as I understand it (although I have a very limited understanding), there are three dimensions that we (usually) work with physically: The 1st would be represented by a line. The 2nd would be represented by a square. The 3rd would be represented by a cube. Simple enough until we get to the 4th -- It is kinda hard to draw in a 3D space, if you know what I mean... Some people say that it has something to do with time. The Question: Now, that is all great with me. My question isn't about this, or I'd be asking it on MathSO or PhysicsSO. My question is: How does the computer handle this with arrays? I know that you can create 4D, 5D, 6D, etc... arrays in many different programming languages, but I want to know how that works.

• 12.10: How to hide bind mounts in nautilus?

  - by Bazon

  Summary: How do I remove folders mounted via bind or bindfs in /etc/fstab from appearing as devices in nautilus left column, the "places" view? detailed: Hello, I mount various directories from my data partition via bind in /etc/fstab in my home directory, eg like this: #using bind: /mnt/sda5/bazon/Musik /home/Bazon/Musik none bind,user 0 0 #or using bindfs bindfs#/mnt/sda5/tobi/Downloads /home/tobi/Downloads fuse user 0 0 (Background: /dev/sda5 mounted to /mnt/sda5 is my old home partition, but I do not want to mount it as a home partition, as I always have at least 2 Linuxes on the computer ...) That works well, but since 12.10 every one of those items is listed in Nautilus in the left column under "Devices". (Where normally USB drives appear, etc.) This is a waste of space (as I have many of such mounts...) and so I would like to have these mounts hidden, just as it was before in 12.04. How can I do that? Thanks!

• Why do I have to reconnect my usb router cable?

  - by Searock

  I have a Iball Baton ADSD2+ Router. It's working fine but the problem is when I boot into Ubuntu I have to unplug the usb cable and then plug it again, then it starts working. Why do I have to re connect my usb cable? Let me know if you need more details. Edit : I am using a direct connection. I mean to say I don't have to enter a username or password. I am connected to internet as soon as I start my router. The problem is if I start my router before my computer I have to re connect my usb cable. Thanks.

• How do I stop Ubuntu Precise freezing/hanging

  - by artfulrobot

  At least once a day I lose work on my (2 different) Intel i5 machines running Ubuntu 12.04. The entire system will freeze/lock-up/hang, and never return. At this point nothing works; even the caps lock key doesn't toggle the light on the keyboard; Ctrl-Alt-F1 won't do anything either. askubuntu.com is apparently where I'm directed for support. I suspect this is a kernel bug. But I simply can't keep losing work like this, so I'm anxious to try whatever it takes to get the thing reliably working. Can you suggest something I can try to fix the problem an existing bug I can follow progress on and contribute to (from users/tester's POV) the most constructive way I can contribute to helping fix the problem, keeping in mind that I do need the computer (so can't do things that might "brick" it!)

• Information about SATA, IDE (PATA) controllers

  - by Adam Matan

  I have a remote computer on which I want to install a new hard drive for rsync backup. The problem is, I don't know what controller technology is used (PATA, SATA, SATA2, ...) and how many available slots are left. I want to spare me an unnecessary drive just for opening the chassis and looking into wires. How do I query the SATA or PATA controllers? I'm interested in the following points: Which controllers exist in the machine How many (and which) disks are attached to each controller How many available slots are there

• Wireless Connection Troubles

  - by James

  I just recently switched from Windows 7 over to Ubuntu 12.04 and have been experiencing some issues connecting to my home's wireless network. The only way I can get it to connect to the network is by disabling IPv4 and IPv6 settings. Even then while it says its connected to the network (3 bars), I'm unable to access the Internet. It connected for a little while after I first installed Ubuntu, but after the first reboot I haven't been able to access the web at all. I have very basic knowledge when it comes to computers and barely any when dealing with Ubuntu and Linux. I'm very happy with Ubuntu apart from this one issue, as before my computer was overheating and crashing, I've yet to experience any of those problems since installing Ubuntu. The information I can give may be very limited since I'm having to use my cell phone to figure out the solution to this. Any help would be greatly appreciated. Thanks in advance!

• Loud fans despite cool system under Linux (but not Windows)

  - by Sman789

  My new desktop computer runs almost silently under Windows, but the fans seem to run on a constantly high setting under Linux. Psensor shows that the GPU (with NVidia drivers) is thirty-something degrees and the CPU is about the same, so it's not just down to Linux somehow being more processor-intensive. I've read that the BIOS controls the fans under Linux, which makes sense given the high fan speeds when in BIOS as well. It's under Windows, when the ASUS AI Suite 3 software seems to take control, that the system runs more quietly and only speeds the fans up when required. So is there a Linux app which offers a similar dynamic control of the fans, or a setting hidden somewhere in the ASUS BIOS which allows the same but regardless of the OS? EDIT - I've tried using lm-sensors and fancontrol, but pwmconfig tells me "There are no pwm-capable sensor modules installed". This is after the sensors-detect command does find an 'Intel digital thermal sensor', and despite the sensors working fine in apps like psensor. Help getting this to work would likely solve the problem.

• how to recover deleted ntfs patition with data entirely while installing ubuntu 13.04

  - by Anson Varghese

  I've installed ubuntu 13.04 onto my hp 2231tx computer. During installation all of my data was erased. I didn't know all of my three partitions would be deleted. I was shocked after finding out that all of my personal data was erased. I didn't know what to do to resolve this problem so I search google for an answer. I found a program called testdisk and I used it to recover about half of my data. Among this data weren't my personal photos and videos. Is there a way to recover the other half?

• Alternative printer driver for Fuji Xerox DocuPrint P205b?

  - by broiyan

  Is there a driver for a similar printer that also happens to work for the Fuji Xerox P205 b? I have tried the generic PCL 5 driver and the generic PostScript driver but they do not work. Any other suggestions? I'm on 10.10 (Maverick). Update The Fuji Xerox website has a Linux driver download as an .iso image. When you open the image you will see 3 drivers. One for HP UX for the PA-RISC and another for Solaris SPARC and one for RedHat x86, x86-64, etc. I picked the RedHat for my computer. It invokes RPM so install that first. The installation script crashes.

• In which directory to write game save files/data?

  - by Klaim

  I need a definite list of directories, one or more per platform, where to put game save files and other game generated data. Either based no the OS developer specification, or because it is common usage if there is no recommandation. Please provide one answer per platform, with different directories. Also, example of how to get the directory location in C++ or C is best, as it's the language you'll have more hard time. Locations: Player's game data (saved games, config). Shared game data (like high-score or config for all computer users). Temporary game data (aka cache directory).

• Update drivers for TL-WN851ND

  - by Tony_GPR

  Today I bought a new PCI wireless card, TP-Link WN851ND, with Atheros AR9227 chipset. It has 2 antennas and is compatible with Wifi N so I thought it would improve the quality of the signal. But after install it on my computer the result is the opposite to expected. It doesn't connect to my network, while my old Wifi BG card connect without problems, I created an access point from my smartphone to try the card, and work, but is very slow loading pages. In Windows 7 works perfectly, so I think the problem is the driver. I have Ubuntu 12.04 LTS with kernel 3.2.0.31, is there a way to update the driver or I can apply a patch to improve the performance of the card? Otherwise, anyone know if there is a work in progress to improve compatibility with this chipset, or is it better to change the card and buy one with better driver compatibility. And finally, which wireless N compatible chipsets have good support under Linux/Ubuntu?

• Java plugin is not working on some sites

  - by Jay

  I have icedtea6-plugin installed on my Ubuntu box. The weird thing is, when I am browsing the internet, certain website are able to use the Java and some websites are not. For instance, I am able to log in to my bank at nordea.dk. They use a Java applet to authenticate the user. But when I try to use keepvid.com, it says "Loading Java Applet". And then after a minute or two it says "Error: Please click here to download Java. If you already have Java, please restart your browser and try again." The thing is I've restarted my computer, closed and opened my browser(chromium) and none of it seems to help. Could someone please point me in the right direction to solve this problem? Thanks.

• Linux Mint Cinamon 17 Qiana, Xfce desktop background problem [on hold]

  - by Serj

  I've installed Xfce4 on my laptop which runs Linux Mint 17 with Cinamon default desktop. Everything works OK and I customized my lightweight Xfce, like change menu location and desktop background that it is similar to my Cinamon desktop and used it for a while. Suddenly after last restart my desktop background becomes black and there is no option for desktop background change when I right click on desktop. I should mention that xfdesktop & didn't help, which tells it's already running. Some icons like Computer, Home and Oracle VM that was already there is showing, but my Trash or other icons did not. I've tried everywhere in xfce4-settings-manager but could not get my desktop background back

• Rails Launcy - open Chromium

  - by tandu

  I'm developing in rails on my computer. I'm just going along with what tutorials say, and I simply cannot find anything about how to use launchy during development on the Internet .. period. There are two problems: I'd like launchy to open Chromium (it opens Firefox). Chromium is set as my default browser. I save files constantly, and launchy will run each time, which is terrible. Is there any way to only get it to run when you actually want? This also applies to guard, but it's not nearly as annoying with guard.

• Black bars around screen? Catalyst Control Center problem?

  - by Josh B

  I just newly install Ubuntu 12.04, and im running an HDMI cable from my computer to my ASUS monitor. Now in Windows 7, i did not have these black bar issues running at 1080p. But now in Ubuntu, i have these black bars. I installed the ATI Catalyst Control Center, and I went to go in to fix the scaling but it is grayed out. As you can see, even with the override box checked i still can not set the scaling. The monitor was set to a lower resolution to hopefully fix it but that did not work either. Does anyone know how to fix this? Thanks.

• Black screen after installing Ubuntu 11.10

  - by Abbas

  I downloaded Ubuntu 11.10 one week ago and burned it to a CD. I installed it on my system which has a 1.5 TB hard. It installed successfully and I clicked on the restart button. The computer restarted and I chose the first option, which was to load Ubuntu. A black screen would appear with a cursor in top left hand side and I think the system was hung. I repeated this process by erasing the last Ubuntu install but I faced a similar problem. Can anybody help me?

  I'm new to rendering and so I don't know if I can speed up the code or that what I'm doing is bad. This is what it looks like But, if I have say 100-200 triangles everything is fine.

Is this normal? The code is here http://pastebin.com/9N6qdEbd game http://pastebin.com/fdkSrPGT mobs I haven't even adding collision detection.

• How do I disable the "enable/disable wireless" shortcut key on my laptop?

  - by Matthew

  On my Dell Studio XPS 16, I sometimes accidentally hit this key. Wireless becomes disabled, and hitting it again does not re-enable wireless. I have to hit it an odd number of times, then restart my computer to re-enable wireless. I can't imagine a situation in which I would want to disable wireless from my keyboard. Is it possible just disable the key all-together, so I can avoid this problem? On a related note, what package do I file the bug against? I'm happy just disabling the key, but that's really just a workaround.

• Bluescreen after Ubuntu 12.10 installation, after recommended boot repair "no filesystem found" please help!

  - by Phil

  After I tried to install Ubuntu 12.10 into my Windows 7 a black screen came up and nothing happened for over five minutes. So I force shutdown my computer and started again on the linux CD. I partitioned the Linux partitions manually and installed Ubuntu. At the next reboot I got a bluescreen from Windows three secounds after loading. I tried to repair the problem by using boot-repair. Then I got out the url: http://paste.ubuntu.com/1430803 And after the next restart he told me that he didn't found the filesystem. Because he didn't found the filesystem it was unable to repair it with the windows CD. Then I tried to repair it with TestDisk and was able to change the Windows Partition into NTFS, but I was not able to repair the windows 7 boot partition. Now I get the message that No Bootloader is found when I restart. Please help me.
