• USB keyboard hit and miss as to whether it will work on boot-up

  - by user208745

  I am new to Ubuntu. Have installed 12.04 on a slave drive while I migrate. Usually booting into Ubuntu goes without a hitch but recently I often find I am unable to use the keyboard, and log-in using the on-screen KB. Sometimes if I remove the USB jack & re-connect it will start working again but not always. I do have an old PS/2 KB which I am using at the moment but.......has anyone any ideas on how to get the USB KB reliably connected? Thanks Dave

• Deleted files not increasing available free space on Ubuntu (as reported by df -h)

  - by Homunculus Reticulli

  I am writing data munging scripts (python and bash), to munge data and import large quantities of text files into a database. I am currently in the test phase, so I am generating several K's of files and deleting them (the files consume about 20G of space). After a test run, I delete the files (sometimes without having imported into the database). I notice that there is a steady decrease in the amount of free space on my disk (as reported by df -h). I don't understand this, as I use rm * (in the data directory), and in the cases where I use Nautilus, I empty the Trash bin as well. Similarly, I notice that when I import the data into the (postgresql) database, and then delete the data from the tables using DELETE FROM tablename;, the size consumed in the postgresql data directory does not go down either. Currently, I have lost approximately 200G from hard drive, and I need to reclaim that - but don't know what to do to reclaim it - any ideas?. I am running Ubuntu 10.0.4 LTS + postgresql 8.4

• Is NTFS-3G safe for writing?

  - by katrmr

  These days, I have to use the NTFS-3G driver to write to an NTFS drive (which will later be used in Windows). But I still remember the olde times of Linux ntfs driver which clearly said in the docs: 'If you write to an ntfs volume, run our special program afterwards which will clean up the damage done.' So, I read through the man, the docs, the Tuxera site and Askubuntu and found no discussion of the write-safety of NTFS-3G. The only thing that was mentioned somewhere is that the driver doesn't support the NTFS journal. So, the question is, can I use NTFS-3G and be sure that I will later read what I have written to the files? Won't, for example, Windows find the journal entries missing and 'clean up' the data according to its own faulty understanding?

• Resize a 2TB partition on a 3TB disk created with fdisk

  - by mR_fr0g

  I recently added a new 3TB hard drive to a headless media server (HP proliant microserver) running Ubuntu server 12.04. I followed this tutorial, which uses fdisk to create a single partition of the maximum size reported by fdisk. I have choosen ext4 format. I then copied across all my media, which took some time. I am guessing that fidisk has a 2TB limit, because du is reporting this as the size. Is there any way to increase the size of the partition to 3TB without having to copy all my media over again?

• 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.

  I recently installed ubuntu onto an extra hard drive and everything booted correctly. However, my Linksys wireless card is not working.

• 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

• 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.

• 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.

• 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

• 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?
