• Windows Wireless Drivers - Install

  - by Justin Y.

  I have nearly ended my journey of making a dual-boot windows xp and ubuntu computer. Along with version 12.04, came the problem with my NetGear WNDA3100v2 wireless adapter. It wasn't compatible. My last step in my adventure is to install the software called Windows Wireless Drivers. I have internet access on my laptop and a flash drive. It would be preferable to receive a link to this program, because I see no link on the website, and I can't download it from the Ubuntu Software Center. Thanks.

• How to reinstall Windows 8 after accidentally wiping it off my HDD

  - by user286538

  So about half an hour ago I decided to try out Ubuntu and in the process of doing so, my hard drive got wiped. My Windows 8 installation, and all the files with it are gone. Since my laptop came preinstalled with Windows 8, I don't have a disk or anything to use to install it again. I guess I'll have to install all of my things again, but first, I just want to know how to get Windows 8 back(will the serial number on the bottom of my laptop work?) so I can get back to an OS I'm familiar with. Any explanations would be great. Please don't be too technical though.

• Optimize bootup sequence

  - by ubuntudroid

  I'm on Ubuntu 11.04 (upgraded from 10.10) and suffering really high bootup times. It got so annoying, that I decided to dive into bootchart analysis myself. Therefore I installed bootchart and restarted the system which generated this chart. However, I'm not really experienced in reading such stuff. What causes the long bootup sequence? Edit: Here is the output of hdparm -i /dev/sda: /dev/sda: Model=SAMSUNG HD501LJ, FwRev=CR100-12, SerialNo=S0MUJ1EQ102621 Config={ Fixed } RawCHS=16383/16/63, TrkSize=34902, SectSize=554, ECCbytes=4 BuffType=DualPortCache, BuffSize=16384kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=976773168 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 AdvancedPM=no WriteCache=enabled Drive conforms to: unknown: ATA/ATAPI-3,4,5,6,7 * signifies the current active mode And here the output of hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2410 MB in 2.00 seconds = 1205.26 MB/sec Timing buffered disk reads: 258 MB in 3.02 seconds = 85.50 MB/sec

• Installing multi-boot Linux system

  - by user94924

  I have a dual (XP/Linux) boot Compaq Presario S4500UK with a couple of spare partitions on the boot drive which I want to use for testing different Linux distros/configs before installing them on "live" machines. I tried this with Oneiric which worked fine until I came to uninstalling the test system. Fortunately Oneiric uses Grub2 and so redirecting the bootloader to work from the original Linux partition was a piece of cake - if a bit annoying. I now need to do some tests on Hardy and DSL (Damned Small Linux), neither of which use Grub2. Question: Is it possible to install a test operating system without adding/replacing the bootloader (ie so I can still use Grub2 from the original partition with its nice interface and recovery facilities)? Is there another way of uninstalling/decommisioning a test OS which doesn't trash the boot loader? (The only way I know to do this is by deleting/reformatting the partition which takes with it the bootloader which is in that partition). Any help would be much appreciated. Tks jg1

• How is this "interface"-like structure/pattern called?

  - by Sebastian Negraszus

  Let's assume we have an XmlDoc class that contains basic functionality for dealing with an XML data structure and saving/loading data to/from a file. Now we have several subclasses, A, B and C. They all inherit from XmlDoc and add component-specific methods for setting and getting lots of data. They are like "interfaces" but also add an implementation for the signatures. Finally, we have an ABCDoc class that joins all the "interfaces" via virtual multiple inheritence and adds some ABCDoc-specific stuff, such as using XMLDoc-methods to set an appropriate doc type. We may also have an ADoc class for only saving A data. How is this pattern called? "Interface" is not really the right word since interfaces usually do not contain an implementation. Bonus points for C++ code conventions.

• Which software should I use on Ubuntu to create a Windows XP LiveUSB? [closed]

  - by user92241

  Possible Duplicate: How to create Windows XP LiveUSB using Ubuntu to replace it Since many programs that I need only work on XP, I need to install Windows XP on my 2 laptops but I can't use an optical drive, which makes using a USB the only option. If it helps, I can tell you that I used to have Vista and Windows 7 on my 2 laptops but I clean installed Ubuntu 12.04 on one, and Lubuntu on the other. Also I have no trace of Windows left on any of my laptops, when I bought my laptops they came without a Windows CD, so I only had a 20GB partition on my hard drives (which I formatted when I clean installed Ubuntu and Lubuntu.) Also, I have no problem with clean installing Windows XP and the reinstalling Ubuntu/Lubuntu so I can dual boot. Thanks! Edit: I have a ISO file ready, on a USB.

• Unable to boot from new SSD after installing from USB

  - by user73725

  I'm using a new SSD with nothing on it. It's installed via USB drive, and boots from USB as well. While in Ubuntu I can see the SSD and other devices. When I install from the desktop (have tried from the boot screen as well), system restarts. It takes me to the boot screen, select boot from first hard disk, nothing, goes right back to boot screen. When I take the USB out, it hangs on "Verifing DMI." If I boot onto the USB I can see the correct files located in the SSD. I have a basic knowledge of computers. Give me any thing you think would help. No other OS's are loaded. Gigabyte ga-k8n-sli 1GB RAM AMD Athlon 64 x2 dual core 3800+ OCZ SSD Agility 3 120GB

• Upgrade from 13.04 to 13.10 fails early on

  - by Bob Lewis

  I am attempting to upgrade from 13.04 to 13.10. Right after the early on message Downloading file 1 of 2 and then it goes on to 2 of 2 the upgrade process dies. A reboot and attempt again fails at the same point. This is a 64 bit system with an SSD for the boot drive. If memory serves me when attempting to do same from the command line I saw some dbus error which may or may not be related. Any help much appreciated. Obviously I could attempt a fresh install which would likely succeed.

• Audio PC Software running on UBUNTU

  - by Stuart

  Hi I recently built my own home studio PC. i5 CPU) 8Gb RAM, solid state drive etc. Basically the fastest PC I've ever built. I have a 32bit version of XP and all the music software I have runs on this. However I want to use all the RAM and can only do so by moving to 64bit Windows. My questions are: Will Ubuntu run my Audio software or would I need to get Linux specific Audio software? Are there any good (pro) shareware linux based multi-track audio software packages? Will VST plug-ins work through UBUNTU? Cheers, Stu.

• Connecting to a Windows SVN server from Ubuntu

  - by skytreader

  I need to access an SVN repo hosted on a Windows machine from Ubuntu. However, even if I supply the proper credentials, it denies me access, apparently because Windows does not allow Linux connections (as they told me); sure enough, I got in when I tried to checkout from my XP partition. While I have my box dual-booted, it is inconvenient to switch just for SVN. So, does anyone know how I can access that SVN repo from Ubuntu? I've tried installing TortoiseSVN and Windows Subversion under Wine but I can't even get them to run; they were asking for some DLLs that I don't know how to supply. I've thought of installing a virtual XP just for SVN but I consider that too extreme and I'd be glad if anyone can advise a simpler workaround.

• GRUB's menu.lst deleted after a kernel update

  - by the_drow

  I have installed ubuntu through wubi and all was well until I updated to the next kernel version. I am now trying to boot into ubuntu and it shows me the GRUB rescue command line. I am able to boost windows and the problem seems to be related to the fact that I have no menu.lst on ubuntu\disks\boot\grub and also it might be related to the fact that wubi wasn't installed to the drive where windows is installed but I am not sure. How do I recover menu.lst? Does the problem lay somewhere else? Is there a way to read the data with a windows tool to just recover my data?

• Frameworks for targetting multiple environments

  - by Werlang

  What should drive the decision behind doing development upon one or more than one framework? For instance, an ERP is (mostly) run on a Windows station. It leverages full access to device's resources, like printers, barcode readers, fingerprint readers and the like. It's usually more responsive and easier do develop with. That being said, some parts of it must be accessed exclusively in self-service mode, by enterprise's customers, suppliers and partners. This could be accomplished with smartphones, tablets, or even desktops running a web browser. What are the economics behind that? Should two team be kept, each one doing work upon its own framework? Or the most permissive framework should be chosen? Should I care something other than HTML technologies? Should I consider native technology for each device?

• Not your typical Permission Denied Question

  - by Todd

  I recently reinstalled Ubuntu 11.10 (64 Bit) on my computer. (My hard drive took a powder) Before, I could "mv" files around with the command. Now when I try I get the permission denied message. I also get the message about "man sudo" when I open my terminal. I am pretty sure I did not get that before. Can I add a user/administrator and change something in my orginal admin that I cannot change myself? I am getting really frustrated with this. I do not recall having the same problem before. I tried qksudo nautilus and it appears to run then it sits there with the cursor blinking but does not move.

• Remote Desktop advice

  - by spoon16

  Coming from Windows, so that is what my expectations are based on. I have a Ubuntu desktop edition instance running as a virtual machine on a server. I would like to use it as my primary open source dev environment but the VNC tools I have used don't seem to be as rich as "Remote Desktop Connection" in Windows. The two things that are missing for me: connecting/logging into a non-console user sessions dynamically resizing the graphical resolution based on the size of the remote desktop window device sharing (USB devices plugged into client shared with remote) Is there an appropriate client that I can run on Windows to connect to my ubuntu dev instance that provides these capabilities?

• Can't copy file (I/O error) Ubuntu Server

  - by QxQ

  I'm running Ubuntu Server 12.04, and basically found out that a couple of files aren't behaving like they should. The file name is r.-1.-1.mca, and I've tried using this terminal command sudo cp r.-1.-1.mca ../ The hard drive is working/thinking for a while, then spits this back out: cp: reading `r.-1.-1.mca': Input/output error cp: failed to extend `../r.-1.-1.mca': Input/output error I have another file behaving like this. My guess is that these files are corrupt, so I tried running the server in recovery mode and it told me to check the file system. However, it didn't come up with any errors. Is there a way to repair these files so I can use them normally again?
