• Unable to Install GRUB in /dev/sda

  - by Henry

  I'm trying to install 12.04LTS on a server but keep running into the unable to install grub error like so "Unable to Install GRUB in /dev/sda". The drives are in raid1 and I'm using fakeraid on a supermicro motherboard, which according to the manual is fully supported. I've tried installing both from USB and CD-R but still no luck. I'm not dual booting with any other OS, just using 2x320gb drives and have been choosing to install using the entire disk. Any ideas what I'm doing wrong or can do to fix this? thanks

• How to set-up a simple subversion workflow

  - by Milen Bilyanov

  I am trying to set-up a simple SVN workflow at home. I am new to subversion (and programming) so I have been reading the official PDF documentations but still not sure about how to set-up my repository. I am working mainly with python, bash and rsl (Renderman Shading Language) So I already have a /dev structure on my disk as this: http://imageshack.us/f/708/devstructure.png/ And I have a /site structure that links to my /dev folder: http://imageshack.us/f/651/sitestructure.png/ So obviously starting to use SVN will change this approach that I already have in place. The question is when I am setting-up my SVN repository for the work I do in my /dev folder: Will I set-up a separate repository for each different programming platform? and Where exactly I should be placing my repository? Thanks.

• Can't Select Continue to install ubuntu alongside them

  - by msknapp

  I'm trying to install ubuntu 14.04 alongside Window 7 on my PC. I got to the installation type page and it detected my windows 7, then asked me what I would like to do. I selected the option to install ubuntu alongside them; however, the continue button was then grayed out. If instead I chose the option to do something else, the continue button was still grayed out. I was given absolutely no explanation for why it was grayed out. The only option that would let me continue was to erase the disk, which I do not want to do. I have two hard disks, and one of them has two partitions on it. The second partition is completely unused, and has a terabyte of space. That's where I wanted to install it. Can somebody please tell me why I can't install ubuntu alongside Windows 7 here?

• Build Your Own Adapter For Cheap Mains Power on Portable Devices

  - by Jason Fitzpatrick

  If you’re looking for a way to build a battery-to-wall-power adapter for one of your portable devices, this tutorial can serve as a template for your DIY adventures. Mike Worth wanted an outlet adapter for his Canon camera, but Canon wanted $75 for it. Not looking to spend that kind of cash on a very simple adapter, he set out to build his own. The build is quite simple, consisting of a transformer with the proper voltage, and a set of dummy battery casings with thumb tacks and washers to serve as the negative and positive leads.

• Copy only folders not files?

  - by Shannon

  Is there a way to copy an entire directory, but only the folders? I have a corrupt file somewhere in my directory which is causing my hard disks to fail. So instead of copying the corrupt file to another hard disk, I wanted to just copy the folders, because I have scripts that search for hundreds of folders, and I don't want to have to manually create them all. I did search the cp manual, but couldn't see anything (I may have missed it) Say I have this structure on my failed HDD: dir1 files dir2 files files dir4 dir3 files All I a want is the directory structure, not any files at all. So I'd end up with on the new HDD: dir1 dir2 dir4 dir3 Hoping someone knows some tricks!

• How to create Windows XP LiveUSB using Ubuntu to replace it

  - by Orion Clark

  I am using an Acer Aspire One netbook with no CD-disk drive, and would like to uninstall Ubuntu 12.04 LTS and install Windows XP in its place. The problem here is that I can't seem to find a program that can put the windows boot files on a USB drive from an ISO file. I have Ubuntu fully installed and have tried using unetbootin. When I tried booting from unetbootin I got a screen with a blue box that had the word "default" in it highlighted. underneath the box there was a countdown that said "will boot from default in 10" after the countdown finished the number would revert to ten and nothing would happen. Can someone tell me another program that would be useful for this please?

• Finding files at more speed

  - by Chaitanya

  I have been using find command to find files on my 1 tb hard disk. it takes very long. then I used locate which proved to be faster with regular update using updatedb. But the limitation of locate is that I cannot find files with certain size or modified/created time. can you suggest me any ideas on how to find files at more speed or in that case how to pipe output of locate command in a way that all other information like size, time, etc. can be displayed or redirected to a file.

• Disable auto-mount for particular partitions on usb drives

  - by nealmcb

  I have a big USB disk with 3 partitions: one for backup and two other bootable ones for installing and testing new distros. I want the backup partition automounted on boot. But I don't want the two test partitions automounted. Despite my use of "noauto" in /etc/fstab, something (gnome?) seems to be mounting them when I plug the drive it. LABEL=mybook /srv/backup ext4 defaults 0 2 LABEL=mybook-root /media/mybook-root ext4 user,noauto 0 2 LABEL=mybook-spare /media/mybook-spare ext4 user,noauto 0 2 In previous Ubuntu distributions it seems that it was possible to configure gnome so it would avoid mounting particular partitions on removable drives like USB: gnome-mount --write-settings --mount-options noauto --device /dev/sda1 This is no longer available in Lucid (when did it go away?) Is there another way to do this now?

• Ubuntu not showing complete list of partitions while installing 10.04 and 10.10

  - by Ravi

  I am a total beginner to Ubuntu. I have tried to install Ubuntu on my 320 gb hard disk and am stuck at the partition page. The problem is, Ubuntu is not showing all the partitions. When I run the live CD and try to see all the drives these are not present. I have presently 4 drives, C: 58 GB D: 48 GB E: 87 GB and F: 102 GB. The F: drive is not shown; at the time of installing it does not show any of the drives, just a chunk of 257 GB, hence I am unable to install Ubuntu on my D: drive. On the C: drive, Windows 7 64 bit is installed.

• Grub failure after cat removed USB drive

  - by user76270

  I had a perfectly working Ubuntu Server system with U12.4 and Server installed and was setting up the mail system. When I was absent from my computer room my cat (furry type) apparently got to play with a USB dongle on an extension cable and removed it. The system went berserk and now will not boot. I ran Ubuntu 12.4 on the install disk and the directory structure and every thing appears to still be on the drives. How do I recover the GRUB boot section without the system repartitioning everything and wiping everything else? Please I am a total newb when it comes to Linux errors and fixing them.

• How to retrieve data from a corruped volume

  - by explorex

  Hi, My Ubuntu 10.10 just crashed(probably due to hardware error and in the end I was getting error like Unknown filesystem ..... grub> .. GRUB console before i could take some action) and i reinstalled the same version form USB stick. I had ubuntu installed in ext4 file system and I am also having the same filesystem in the same hard disk on different drive. When I try to access my previous filesystem, i get error Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda6, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so I had some important files in the previous volume, I don't know how to retrieve them. And what are the chances that I would get the same outcome (hardware error)? Please help me!

• "mountall: Disconnected from Plymouth" error in VirtualBox

  - by jonpavelich

  I installed Ubuntu (from the 11.10 Alternate CD, selecting "command-line only" mode before installing) in Virtualbox (Mac OS X Lion host) like I've done numerous times before. Installation finished without any problems, and I rebooted into my new system. Got the splash screen, it loaded, and right where it should've given me a login prompt, I got (in orange) mountall: Disconnected from Plymouth. I can just hit control + alt (option) + F1 to get the login prompt on tty1, and the system acts normally. This happens on every boot. The disk has two partitions, a 250 MB /boot partition and a 99.75 GB encrypted partition. The encrypted partition has LVM on it. One volume group, 3 volumes (swap, / (root filesystem) , and /home. At first I thought the error was from one of the LVM volumes not mounting, but they are all accessible. It isn't a critical error, but it is annoying. Any ideas?

• How can I store all my level data in a single file instead of spread out over many files?

  - by Jon

  I am currently generating my level data, and saving to disk to ensure that any modifications done to the level are saved. I am storing "chunks" of 2048x2048 pixels into a file. Whenever the player moves over a section that doesn't have a file associated with the position, a new file is created. This works great, and is very fast. My issue, is that as you are playing the file count gets larger and larger. I'm wondering what are techniques that can be used to alleviate the file count, without taking a performance hit. I am interested in how you would store/seek/update this data in a single file instead of multiple files efficiently.

• Disc Drives: An Endangered Species

  - by Jason Fitzpatrick

  More and more computers are shipping sans-disc drive leading many industry watchers to proclaim the optical disc an endangered species on its way out. Do you still use your drive or are you letting the disc go? CNN Tech reports on the trend: Apple’s new iMac, its flagship desktop computer, was released Friday. For the first time, it has no disc drive. This marks a trend that has already begun on some laptops, like Apple’s MacBook Airs, and of course with mobile devices like smartphones and tablets. “Over time, an optical disc will be as much of an historical curiosity as a floppy disk,” said Michael Gartenberg, a tech-industry analyst with research firm Gartner Inc. According to Apple, where sleeker, thinner designs are always en vogue, dumping the disc drive was a no-brainer.

• Drawing of a huge model - How to regain performance?

  - by marc wellman

  I have a huge model I want to draw in my XNA application but because of its size I am experiencing a tremendous loss of performance. The model has about ~50 000 000 edges and has a size on disk of 205 MB in DirectX Format. Please don't ask whether this model has to be that big - yes it has! Is there a way to transfer the model directly to my GPU in order to let the GPU do the drawing like when transferring a VertexBuffer like this: graphicsDevice.Vertices[1].SetSource(_instanceBuffers[i], 0, _sizeofMatrix); because when I try to fill a vertexBuffer with all the vertices I am getting a OutOfMemoryException.

• Xubuntu, LXDE, USB Booting

  - by Kosciak

  Welcome, My problem appeared today - I was using Xubuntu for a long time, but find out that LXDE should be faster than Xfce, so I installed it. After installing I followed tutorial for removing Xfce, cause disk in my computer is very small and I wanted to release some free space. I used command from this tutorial: How to remove xubuntu-desktop? but instead of remove I entered purge command… and rebooted at the end. And I uninstalled whole my things. The problem is in installing system again - it's old Sony Vaio laptop (PCG-GR250) and I have broken CD-DVD drive. It's possible to boot from USB? I can access recovery mode, will this help me? Please answer fast, because it's my brother computer, and his going to kill me if I won't fix this fast :(

• How are minimum system requirements determined?

  - by Michael McGowan

  We've all seen countless examples of software that ships with "minimum system requirements" like the following: Windows XP/Vista/7 1GB RAM 200 MB Storage How are these generally determined? Obviously sometimes there are specific constraints (if the program takes 200 MB on disk then that is a hard requirement). Aside from those situations, many times for things like RAM or processor it turns out that more/faster is better with no hard constraint. How are these determined? Do developers just make up numbers that seem reasonable? Does QA go through some rigorous process testing various requirements until they find the lowest settings with acceptable performance? My instinct says it should be the latter but is often the former in practice.

• How to Make a 9 Layer Density Column [Video]

  - by Jason Fitzpatrick

  Density columns, layers of varying density liquid in a glass cylinder, are nothing new in the world of science demonstrations, but this nine layer one with seven floating objects is something to see. Courtesy of Steve Spangler Science, the experiment goes above and beyond the traditional five layer column by adding another four layers and sinking objects of varying density into the column. The end result is a colorful demonstration of the varying densities of liquids and solids.
