• How do I restore the privacy pane of the system settings?

  - by Sparhawk

  Checking out screenshots of the system settings in Ubuntu 12.10, it seems that I am missing a few. When I open up my settings, I cannot see Privacy, Backup, and Management Service. Also, nothing comes up when I search the Dash for these words. In a previous edition of Ubuntu, I purged Ubuntu One (with sudo apt-get purge ubuntuone-client python-ubuntuone-storage* ubuntuone-couch ubuntuone-installer) and appropriately, I cannot see the Ubuntu One icon. I've also previously purged unity-lens-music Perhaps I purged some metapackage that removed the others? In any case, how do I restore the privacy pane (as well as the other icons)? Also, any suggestions for what I did to remove the packages in the first place (and hence how to avoid this problem in the future)?

• Get Rhythmbox debugging info

  - by skytreader

  I'm having a weird problem with Rhythmbox that no one else seems to have. When I pause on any audio CD, I can't get Rhythmbox to play it again. I've tried various workarounds including trying to play next/previous track, trying to manually move the seek bar, etc. but to no avail. When this happens I've no choice but to remove the CD from my drive and insert it again. There does not seem to be anything weird with my system when this happens, apart from the fact that Rhythmbox isn't playing as it is supposed to. Is there anything I can do to get more info on why Rhythmbox is acting up as such?

• Disqus Comment Form Missing from Posts

  - by Saad

  I decided to transition from IntenseDebate to Disqus for the blog. So I uninstalled ID via their uninstall process (you upload the template to them, they remove code, you reupload your new template onto the site). Then I went to install Disqus into the site through their Blogger widget method. The problem is that there is no comment form present on any of the blog posts' pages. For example, when you click on the 'Comments' link it jumps to #disqus-thread but there is no thread there. So is there any fix that I can do in order to make the comment form appear? I checked Disqus' knowledgebase for Blogger installation but as far as I can tell my template should be compatible.

• Force usb to use same device id, instead of new one

  - by m s kumar

  I am having some trouble in automating the task. I am testing some android based mobiles in linux machine. The automation script uses the device id under "/dev/bus/usb/001/"053" it will be always under bus 001 only.. But the dev is will be random like if i insert one mobile then the dev id will be 053, if remove and insert it again then the dev id will be 054.. The problem is, when some tests runs on the device and if device gets rebooted then new dev id is showing for the rebooted one and my scripts failing due to new dev id.. Is there any way to force usb devices to use same dev id instead of new one. So that there will be no issues to my tests even after device reboots. Thanks in advance.

• Once mounted using TrueCrypt, cannot unmount

  - by zeiger

  I have an external HDD and use TrueCrypt for keeping encrypted file containers. After mounting, whenever I try to dismount a file container (using TrueCrypt 7.0a on Ubuntu 11.04), it just does not happen and I get the following message: device-mapper: remove ioctl failed: Device or resource busy Command failed Further, if I close TrueCrypt and then try to start it again, it says that TrueCrypt is already running, but I cannot access it from the Unity sidebar (because it is not there). Also, if I power down my external HDD, the TrueCrypt volume still shows as one of the mounted volumes, but I cannot do anything with it. Any possible work around? I remember this NOT happening in earlier versions of Ubuntu so I am guessing there is something to do with 11.04. Thanks

• What is the intention behind asking weight of plane?

  - by AKS

  I was asked this question "How would you find weight of Aeroplane" in an interview and I am not sure why this question was one of the two question asked in the interview. I tried to answer it using all possible ways but could not give the correct answer.(found the correct answer after google search) How much such questions decide your selection in the interview? Here was my approach: 1. If measurement of plane is given then i will calculate volume and multiply by density, will consider fuel weight plus other dead weight. 2. Using water displacement method if i can put plane in water and somehow measure how much water is displaced. But found using google search that right approach was to put place on a ship and mark the level of water on the hull, then remove plane and then ship will go up. And start putting weight on the ship till marked hull reaches the water level.

• Sound Problem due to wrong driver installation

  - by Starx

  First of all, the audio used to play from the speaker but whenever I connected a headphone or speaker in the I, the sound didn't came. So I installed a realtek sound driver to fix this (actually I didn't find any relevant driver for my sound card so I installed it hoping it would show some light) When I rebooted the system, my sound is completely gone and now ubuntu does not detect any sound devices in my system. I clearly installed wrong driver, now I need to remove and go to previous stage and find a correct driver. My laptop is: Dell Studio 1747, uses a speaker Creative Labs Sound X-Fi MB Sound Blaster and the chipset is INTEL PM55. How can I fix this?

• Fixing Broken Links to Entries on This Blog

  - by Shay Shmeltzer

  I just found out that some built in redirects that were in place on the Oracle Blogging platform were removed, and as a result there is a good chance that if you were directed to an entry on this blog that is a bit older you'll get a 404 error. Luckily there is a simple URL hack that you can use to fix this - switch the "year/month" part for "entry" and then remove the ".html" from the URL. So for example instead of :  https://blogs.oracle.com/shay/2010/10/passing_parameters_to_adf_appl.html use: https://blogs.oracle.com/shay/entry/passing_parameters_to_adf_appl I fixed the links on my "Archives" page so you can also look for the entry by title there. Sorry for any inconvenience.

• is gnome 3 is slow or my machine?

  - by user103054

  I have Dell XPS 15 i7 - 2360 with nvidia 525M (1GB) with optimus running Ubuntu 12.10 64 bit and have bumblebee installed for optimus. Recently I installed Gnome Shell to give it a try and found it sort of lagging under few scenarios though rest all is butter smooth. When I click on Date gnome 3 it appears as if a second has elapsed before the window is drawn. But others panel items like network or volume looks fine. In gnome 3 when I'm on dash with (window preview) if I remove any of the windows before the remaining windows reshuffle it takes about 2 seconds (noticeable clearly). Everything else is fine in both unity and Gnome Shell. What is causing this slowness? Is Gnome Shell is really slower?

• Problem in Loading certain Websites in Ubuntu 11.10

  - by Cody

  I have a DSL connection in Ubuntu 11.04 and am having problems loading content from certain websites mostly providing CDN services. I have tried every suggestion asked at problem loading internet pages as I have the same problem. Also tried to remove the DNS Cache and Browser Cache. I have tried using Google DNS Server: 8.8.8.8 and 8.8.4.4, but nothing seems to work. Though when I browse the websites in Windows XP then it does not pose any problem. This problem has come up only few days ago and has affected every browser(Chrome, Firefox and Opera) in Ubuntu 11.04. Thanks in advance.

• How to get working cups command line tools on Server 14.04

  - by Nick

  It looks like some of the commands like lpr and lprm have broken versions that don't work with cups. These commands worked properly on 10.04. lpr for cups has an -o option, but no lpr is intalled when cups is installed, and the lpr installed with apt-get install lpr does not have the -o option and does not appear to be the cups version of lpr. man lpr shows BSD General Commands Manual at the top, where man lpr on the Ubuntu 10.04 server said Apple, inc in the same spot. which leads me to believe the "wrong" lpr is in the "lpr" package or package names got moved around. There is also a lprng package, but trying to install it wants to remove cups and cups-client. lprm also returns lprm: PrinterName: unknown printer when PrinterName is in fact a valid printer installed with cups and does appear in lpstat -t. How do I get the proper cups versions of lpr working on Server 14.04?

• Used DBAN to wipe Lenovo u410 then installed Ubuntu. Need to install windows 8, but I get an error.

  - by David

  When I try to boot from my windows 8 USB (tested on a separate PC), I get this error text "The boot configuration data for your pc is missing or contains errors." I want to install windows again so I can fix a battery issue I'm having. Lenovo's power management app has an option to keep the battery at 60% if the laptop stays plugged in most of the time. I enabled this, then formatted without changing it back. I think there might be a raid setup that I may need to remove or something. I don't mind removing Ubuntu and starting fresh. I would just love some help with all this, I'm a noob when it comes to Linux.

• HP Pavilion tx2000 - Wifi adapter no longer works after moving from 12.04 to a 12.10 clean install

  - by Marek L.

  I have a HP Pavilion tx2000 that I have been running Ubuntu 12.04 on for a couple of months without any problems (wifi worked great) until yesterday when my hard drive failed. I replaced the hard drive and decided to install Ubuntu 12.10. Unlike 12.04, the wifi did not work after the installation finished and all the updates where installed (over Ethernet). The network drop down in the top right didn't even show a wireless option. I Googled about for a bit and found some solutions that seemed like they might work. Unfortunately they did not. Here is what I tried: sudo apt-get remove bcmwl-kernel-source sudo apt-get install b43-fwcutter sudo apt-get install firmware-b43-lpphy-installer Restart the computer. And the wifi still didn't work. At which point I panicked a bit and tried to undo the previous commands by running: sudo apt-get remove b43-fwcutter firmware-b43-lpphy-installer sudo apt-get install bcmwl-kernel-source Restart the computer. The wifi still doesn't work. This is where I stopped because I have no idea what I am doing and don't want to mess something up. The network drop down still doesn't show a wireless option and the hardware wifi switch on the laptop is amber (it turns blue when the wifi is on). Using the hardware switch does not change the color. Output from: sudo lspci ... 08:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01) ...

Pushing the hardware switch turns the hard block back on and I have to run sudo rfkill unblock all multiple times again to turn it off. Any help is appreciated!

  I installed Ubuntu 12.04 from Windows 7 using Wubi. For reasons I won't elaborate here, I had to reinstall Windows 7. Now I want to uninstall Ubuntu. But there is no entry for ubuntu in Windows' Add/Remove Programs anymore. What I tried: running the Uninstall executable from Ubuntu's installation folder, which didn't do anything. delete the old installation folder No matter what I do Ubuntu continues to show up as a boot option together with Windows 7 whenever I start my machine. How do I completely get rid of the Ubuntu installation? Thanks.

• Why ubuntu does not use the kernels installed by automatic update?

  - by Guillaume Coté

  I used the script describe in this question to list the kernel installed on the computer : How do I to remove or hide old kernel versions, to clean up the boot menu? In the 3.2.0, I have 33, 34, 35, 36, 37, 38, 39, 41, 43, 44, 45 and 48. I would expect to be running 3.2.0-48 after a reboot, but I am still running 3.2.0-32. Why the kernels installed by auto update are not used? [I am running 12.04 LTS] /boot/grub/menu.lst was modified for the last time June 16 2013, it contains 3.2.0-32-generic 2.6.32-45-generic 2.6.32-44-generic 2.6.32-43-generic A recovery for each of those and a memtest. I would have expected the kernel between 3.2.0-33 to 3.2.0-48 to be in this file before 3.2.0-32.

• How should I update Ajax Control Toolkit in VS 2010?

  - by Soham

  Suppose if there is a new version available of Ajax Control Toolkit then how should I install/update it in my visual studio 2010 which has already install older version of same toolkit? I would like to install new one while older toolkit would totally uninstalled, because mostly new toolkit always has all controls that were in the old toolkit & also some new controls. Then 1) Should I've to remove .dll file in my toolkit installation folder and place new .dll file there? If I do so then will VS 2010 automatically delete older entries of toolkit controls in .NET Components list and place new control there? Or 2) Should I've to uninstall old toolkit manually i.e delete .dll file and uncheck all entries in .NET Components list & after that install new one from scratch?

• Colorize with a given color a texture

  - by Pacha

  I have a texture and I want to "colorize" it with a given color, lets say cyan (#00ffff) or purple (#800080). What I want to do, is get all the pixel values from the texture, and remove the color and keep the "brightness" and "saturation" and apply to the desired color. There is a tool in GIMP to do this called Colorize (Colors -> Colorize.. while editing), I made an example below. This is will all be done in a shader (GLSL), although this is probably a general algorithm.

• Multiple version of Grub?

  - by DanielGibbs

  I am running Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-29-generic-pae i686) which according to the Ubuntu documentation contains Grub2. However grub --version gives me grub (GNU GRUB 0.97), but grub-mkconfig --version gives me grub-mkconfig (GRUB) 1.99-21ubuntu3.4 Do I have 2 versions of Grub installed simultaneously? If so, what is the easiest and safest way to remove one. If not, which configuration file should I edit? I have edited /etc/grub.d/40_custom to contain a password, but running update-grub does not appear to include this in the grub.cfg file.

• On a queue, which end is the "head"?

  - by Aidan Cully

  I had always thought that the "head" of a queue as the next element to be read, and never really questioned that usage. So a linked-list library I wrote, which is used for maintaining queues, codified that terminology: we have a list1_head macro that retrieves the first element; when using this library in a queue, this will be the first element to be removed. But a new developer on the team was used to having queues implemented the other way around. He described a queue as behaving like a dog: you insert at the head, and remove at the tail. This is a clever enough description that I feel like his usage must be more widespread, and I don't have a similarly evocative description of my preferred usage. So, I guess, there are two related questions: 1, what does the "head" of a queue mean to you? and 2, why do we use the word "head" to describe that concept?

• How to reinstall many removed packages at once?

  - by Logan

  I used sudo apt-get remove python command and accidently removed a bunch of packages that were required. I logged in via command line and installed ubuntu-desktop again but there are other packages that are missing, and I'm looking for a way to easily reinstall those removed packages. Since there's the log at software-center I wanted to ask what the easiest way might be to roll back changes or extract the removed packages list from the software center... note: I typed sudo apt-get install .... .... ... ... for about two dozen of those removed programs in that list, but when I pressed enter it didn't install any of them because some package names couldn't be found. The programs were removed at the same date.

• Not using nofollow for UGC links

  - by Noam

  My site contains many links that were user generated so I've added a rel=nofollow to them. I'm considering removing that tag at least partially, as these are most of my outgoing links and I've come to understand it isn't a good SEO sign to not have outgoing followed links. Although these are external sites, I have some data on the popularity and categorization of these sites. I'm trying to decide between two options: Removing the nofollow link for popular sites in most categories. Removing the nofollow for links that are in specific categories that represent the categorization I would like to achieve for my site. For example if this is a site about Basketball only remove the nofollow for links that are from sport sites. As these are both not exactly natural approaches, can this hurt me? Which option would you recommend?
