• Installing 12.04 on a Dell Dimension 2200

  - by Corn

  I'm attempting to install Ubuntu from a 12.04 live CD. A few boots have gotten me (initframs) in BusyBox. During one attempt, it actually said it had loaded Ubuntu and gave me a command prompt, before quickly taking it away. After the working attempt, the HDD was removed from the BIOS menu for some reason, but was auto-detected on a boot into Windows. I haven't got a clue what I'm doing wrong. I don't get the little Ubuntu graphical splash while it boots either, but F6 (or rather spamming many keys) will display a list of the various [starting]/[stopping] it's doing.

• How do I install latest NVIDIA drivers?

  - by Shahe Tajiryan

  This is what I am trying to do. I downloaded the latest driver for my VGA from http://www.nvidia.com. The installation needs the X11 to be shut down, so I log out of my account, then press CTRL+ALT+F1, then log in with my username and passowrd, then run the command sh NVIDIA-Linux-x86_64-285.05.09.run in every possible way, I have even tried CHMODing the package with 777 permissions, but still I'm getting the sh: can't open NVIDIA-Linux-x86_64-285.05.09.run error. Any help would be greatly appreciated.

(it has 3 partitions, 1st includes my data on ntfs file system, second is linux swap now, and third ex4 filesystem) Of course i don't want to lose my data on ntfs partition. Anyway i installed ubuntu on ex4 filesystem, selected sda as device for bootloader (not sda1,2 or 2). But i got error Error:unknown filesystem Grub rescue I tried ls command. It gives (hd0) , (hd,msdos1), (hd0,msdos2) and (hd0,msdos3). then tried ls (hd0)/, ls (hd0,1)/, ls (hd0,msdos2)/, ls (hd0,msdos3)/ to find the linux filesystem to boot.

• Why is "sudo virsh" hanging in the console?

  - by technophobia

  I wanted to experiment with OpenStack on my iMac: So I installed Ubuntu Cloud Live Image on a VM and I also ran DevStack on a fresh Ubuntu 64-bit Server VM. The DevStack script hangs on the following line: instances=`sudo virsh list --all | grep $INSTANCE_NAME_PREFIX | sed "s/.*\($INSTANCE_NAME_PREFIX[0-9a-fA-F]*\).*/\1/g"` I commented that block and ran the script again, this time it did not hang; thus completing its run. I attempted to run sudo virsh list --all on my CloudLive VM and it just hands until I break out of it. Why is sudo virsh hanging? Your help is appreciated. Note 1: The virsh command responds without sudo. Note 2: Not sure it matters, but I'm running my Virtual Machines in VMWare Fusion.

• windows system (bootloader) partition accidently deleted during multiple installs

  - by S.Y.T.

  After experimenting with multiple variations of backtrack and xbmcbuntu variations of Ubuntu with dual boot successfully, my windows partition became unrecognizable to grub. I used my windows boot CD to try to correct the problem. However, I deleted all partitions except for the NFTS one that contains my old windows install. (And, merged all other ones into that in hopes of getting back to the windows boot loader and out of grub) Now, all I get is a grub command prompt when I try and boot the system (how??? - I thought I deleted grub) And, now the windows boot disc doesn't even recognize the install. I've tried TRK to try and resolve the problem. Though I must admit ignorance in correctly using this utility. I've searched for other answers to this problem. Any help would be much appreciated. S.Y.

• What Design Pattern is seperating transform converters

  - by RevMoon

  For converting a Java object model into XML I am using the following design: For different types of objects (e.g. primitive types, collections, null, etc.) I define each its own converter, which acts appropriate with respect to the given type. This way it can easily extended without adding code to a huge if-else-then construct. The converters are chosen by a method which tests whether the object is convertable at all and by using a priority ordering. The priority ordering is important so let's say a List is not converted by the POJO converter, even though it is convertable as such it would be more appropriate to use the collection converter. What design pattern is that? I can only think of a similarity to the command pattern.

• share folder in server torrent daemon like in DC(Direct Connect )

  - by alex_bubuker

  So my question: is it possible to share on a server torrent daemon/application a whole folder with films? I had expirience with DC(Direct Connect) applications and it worked well. I selected folder and exec command share == other people stared to download files from my computer. In my expirience with torrent application you should first create torrent file and then people can download file from you. So is there any torrent client/plugin for torrent client that DC-like behaviour become possible? If it is possible at all ... Thank you

• BCM4313 Wireless on Ubuntu Server 12.04

  - by KJ Tsanaktsidis

  I'm trying to run an old netbook with Broadcom BCM4313 wireless as a print server with Ubuntu Server 12.04. Setting up the wireless without the GUI, however, is proving problematic. I do think however I've narrowed down the problem. I've tried both the wl driver (from bcmwl-kernel-source) as well as the (included) brcmsmac driver. With both of them, when I issue the command iwlist wlan0 scanning (eth1 for wl), I only see neighbouring networks- not my own. I believe this might be because my networks are n-only, but my neighbouring networks are mixed mode (I suspect this because the output of iwlist wlan0 scanning shows "Bit Rates" only as high as 54 Mb/s). Any ideas how to go about getting this thing to connect?

• How to Enable SideLoading in a SharePoint Site

  - by Damon Armstrong

  I was trying to deploy a SharePoint App for the first time and ran into an error about SideLoading not being enabled on the site. The solution is fairly simple – you just have enable the Developer feature on the site.  Unfortunately, it’s a hidden feature so you have to do it through PowerShell.  While searching the internet for the command to enable the feature I kept running into really long scripts that seemed overly complicated.  Fortunately, Jeff (a friend at work) sent me this snippet that is very concise and does the job: Enable-SPFeature e374875e-06b6-11e0-b0fa-57f5dfd72085 –url http://yoursharepointbox/site/ Obviously, you will need to update the URL to match your environment!

• Calendar icon in unity shows wrong date

  - by felix

  There is a column of icons in unity on the far left and one of them has the number "31" in big numerals. If you mouse over it it says "Google Calendar" and if you click on it you get google calendar which of course shows the correct date. Today is November 3. Shouldn't it say "3" instead? If I type "date" from the command line I get Sun Nov 3 21:19:37 GMT 2013 I see this was fixed for Chrome at least in 2011 http://gmailblog.blogspot.co.uk/2011/04/5-years-of-google-calendar-and-new.html .

• Solaris 11 features: nscfg

  - by nospam(at)example.com (Joerg Moellenkamp)

  As you may have noticed many configuration tasks around name services have moved into the SMF in Solaris 11. However you don't have to use the svccfg command in order to configure them, you could still use the old files. However you can't just edit them, you have to import the data into the SMF repository. There are many reasons for this need but the ultimate one is in the start method. I will explain that later. In this article i want to explain, how nscfg can help you with with the naming service configuration of your system. Continue reading "Solaris 11 features: nscfg"

• KeyTouch remaps the delete key

  - by Robert Gowland

  I installed KeyTouch, but it decided that the delete key should be the KeyTouch hot key. So, when I pressed deleted, KeyTouch came up. Next I uninstalled KeyTouch and now the delete key doesn't do anything. Is there any way to remap the delete key to actually delete? Notes: I tried reinstalling KeyTouch, and the same thing happens. KeyTouch does not allow the user to map the delete key. EDIT xev shows keycode 119 when I press the delete key xmodmap shows keycode 119 mapped to Delete NoSymbol Delete running xmodmap -e "keycode 119 = Delete" from the command line does not resolve the issue

• nvidia-package in 12.10 somehow not same like in 12.04 resp. X-lib not complete?

  - by dschinn1001

  Not knowing if this has to do with new kernel-update automatic done by ubuntu 12.10 ? it seems that kernel 3.2 in 12.04 has not these problems with nvidia-drivers ? I tried to install the actual google-earth as deb-package with dpkg -i it seems to be no problem, but when I type command: google-earth in terminal, there comes up the report among else: Xlib: extension "NV-GLX" missing on display ":0". Xlib is installed completely and nvidia-driver is de-installed (then reboot) then re-installed again. the report of google-earth stays the same: Xlib: extension "NV-GLX" missing on display ":0". ubuntu 12.04 was working quite good with google-earth. however: bumblebee seems to be taken out of program ? ( or needs to be re-edited ? ) Don't hurry too quick with solution, I can wait !

• Update GRUB to reflect changed partition location

  - by soandos

  I currently have 3 partitions: Windows, Ubuntu, and swap. I want to move my windows partition by about 20GB. When I try to do this in GParted, it tells me that this will mess up GRUB, and that there is a page that can resolve these issues. However, this page does not actually mention my issue. I am not moving my boot partition (Ubuntu). How can I force GRUB to look for operating systems that are on the drive? I know that this is possible, because when Ubuntu was installed it found Windows without any issues. Additionally, if I create a copy of a partition, how can I add that to GRUB (I assume it will be the same command as above, but if not, what would it be)? Note: OS prober is mentioned here but it doest not list how to use it, or where to find it.

• Encryption Password help!

  - by Carlos L.

  Ok so let me summarize this up. I encrypted my Home to protect against hackers of course when I first installed Ubuntu. It loaded up the Terminal and was attempting to show me my encryption password incase it ever needed to be used. So I thought "Ehh what the heck, I can find it out later..." So I closed Terminal and went on with the (amazing!) Ubuntu life. But now I am having to install Java JDK 7.0.0.4 onto my computer to ya know, play games and such. But it is asking for my password for the encrypted Home folder but it never gave it to me... HELP!!! Does anyone remember the command for Terminal to give you you're randomly generated Encryption password pop up on the famous purple window? Please give legitimate answer and fast please!

• Can't control connection bit rate using iwconfig with Atheros TL-WN821N (AR7010)

  - by Paul H

  I'm trying to reduce the connection bit rate on my Atheros TP-Link TL-WN821N v3 usb wifi adapter due to frequent instability issues (reported connection speed goes down to 1Mb/s and I have to physically reconnect the adapter to regain a connection). I know this is a common problem with this device, and I have tried everything I can think of to fix it, including using drivers from linux-backports; compiling and installing a custom firmware (following instructions on https://wiki.debian.org/ath9k_htc#fw-free) and (as a last resort) using ndiswrapper. When using ndiswrapper, the wifi adapter is stable and operates in g mode at 54Mb/s (whilst when using the default ath9k_htc module, the adapter connects in n mode and the bit rate fluctuates constantly). Unfortunately, with this setup I have to run my processor using only one core, since using SMP with ndiswrapper causes a kernel oops on my system. So I want to lock my bit rate to 54Mb/s (or less, if need be) for connection stability, using the ath9k_htc module. I've tried 'sudo iwconfig wlan0 rate 54M'; the command runs with no error but when I check the bit rate with 'sudo iwlist wlan0 bitrate' the command returns: wlan0 unknown bit-rate information. Current Bit Rate:78 Mb/s Any ideas? Here's some info (hopefully relevant) on my setup: Xubuntu (12.04.3) 64bit (kernel 3.2.0-55.85-generic) using Network Manager.

  I installed 12.04 on my wife's Dell laptop to replace 10.04. The code for the Broadcom drivers is broken and I am a user, not a coder. Does any available release of Ubuntu have the drivers in place so I can install and run and get my life back after days of thrashing around. I am willing to do some work, but I am not up to heavy duty command line activity. Please help if you can with any information. Thanks in advance. Matt

• What is the difference between Times and Dup in Assembly Language?

  - by Total Anime Immersion

  In a bootloader, the second last line is : TIMES 510-($-$$) db 0 Now, will this command also do the same : db 510-($-$$) DUP (0) If not why? I know what TIMES does, but its not mentioned in my x86 book by Mazidi (Pearson Publication). Any idea why? And what is the meaning of the $ sign exactly? Different sites have different information about $. And is the line TIMES 510-($-$$) db 0 absolutely necessary even if my bootloader code is of 512 bytes in size? So can anyone help me with these questions?

• Ubuntu frozen on boot screen; boot repair fails due to X11 and gtk

  - by anandsun

  I have a year-old HP Pavilion dv6 with Intel i7 processors and graphics card. I had Windows 7 but last week I dual booted Ubuntu. It was working fine until today. I did the following things: Updated Gnome and installed Gnome tweak tool Uninstalled Chromium browser Uninstalled Google Chrome Moved jdk and jre folders from ~/ to /bin using sudo Moved Adobe folder from ~/ to /bin using sudo Then I restarted. Ubuntu froze for half an hour on the purple boot screen. Something I did must have broken it. So, I hit Ctrl + Alt + F1 and managed to log in through the command line. From there, I ran sudo apt-get update and sudo apt-get upgrade. I also updated grub. I also installed boot-repair. However, I cannot run boot-repair, because I keep getting the following errors: Autolaunch error: X11 initialization failed RuntimeError: Gtk couldn't be initialized.
