• 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)?

• Problems with HP laptop

  - by Jan

  So the problem is...every time I reboot or shutdown laptop and when the laptop is booting again I get screen (before loading OS) that HP discovered overheating and system went into hibernate. But the point is that laptop is not overheating nor going into hibernate by itself. Also becouse of the hybrid graphic cards I cannot install additional drivers. Desktop resolution and all works perfectly but I cannot use unity 3D also openGL doesn't work as it should (with cairo docks) As i've read some posts, people say that switcheero doesn't work on 12.04 so I haven't tried it.

• Linux kernel regression on power usage

  - by dago

  Webupd8 reported this power management fix for the 2.6.38 Linux kernel regression: Add the following to the boot grub line "pcie_aspm=force" My question - how does this suggested fix differ from this hint from powertop: Suggestion: Enable Device Power Management by pressing the P key, which execute the following action: find /sys/devices/pci* -path "*power/control" -exec bash -c "echo auto > '{}'" \;

• How to take a screenshot every n second?

  - by Seppo Erviälä

  What software can I use to take screenshots with a set interval? I'd like to take screenshots every 2 second or so. Command-line and GUI are both ok. I'd prefer software that can also resize and compress each screenshot. EDIT: What I realized I really wanted to do was take a screenshot and a picture with webcam at the same time. I ended up doing some python: import threading import os def capture(i): i += 1 threading.Timer(2.0, printit, [i]).start() fill = str(i).zfill(5) os.system("scrot scrot-%s.jpg" % fill) os.system("streamer -o streamer-%s.jpeg -s 320x240 -j 100" % fill) capture(0)

• Trouble launch byobu with custom windows.NAME file

  - by Brendan Piater

  Apologies if the solution is obvious but I'm stumped! I want to launch byobu from within my Gnome 3 desktop environment on 12.04 but it's not working for me as yet. Here's what I have: created a windows list file ~/.byobu/windows.mrb then tried to launch byobu from within the gnome terminal with: $ BYOBU_WINDOWS=mrb byobu But it gives me the default windows list, NOT my windows list. I followed these instructions from the wiki: http://goo.gl/omgl8 Here is a sanitised version of my windows.mrb file: screen -t local bash screen -t name1 ssh xxx@xxx screen -t name2 ssh root@xxx screen -t name3 bash Appreciate the time and effort. Cheers Brendan

• Fans are noisy and battery life is low

  - by Igor Ryzhov

  I worked on Windows 8 previosly and I never had problems: my laptop was quiet and battery life was about 5-6 hours without charge. Then I installed Ubuntu 12.10 and my problems started: now fans are always on and have very strong noise and battery life shortened to 1-1.5 hour! How can I solve this problem?

• Java Not Recognized As Default Application

  - by John

  I just installed java according to this article, and 'java -version' displays java version "1.7.0_07" Java(TM) SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) 'update-alternatives --config java' returns this: There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/bin/gij-4.6 1046 auto mode 1 /usr/bin/gij-4.6 1046 manual mode * 2 /usr/local/java/jdk1.7.0_07/bin/java 1 manual mode Press enter to keep the current choice[*], or type selection number: with update-alternatives --config javac (or javaws) returning similarly. however java isn't listed in the default applications menu when I click on a .jar file and go to "open with application". I tried to install java this way, and on the update-alternatives part of the command returned me: /etc/alternatives/[java,javac,javaws] is dangling, it will be updated with best choice I just confirmed that I can use java, as 'java -jar file.jar' does work. Just figured that I'd mention it, don't know why I didn't before, but when I right click on a .jar file, java 7 run-time isn't even listed there, it seems that the file-manager isn't recognizing it as a program, but it is there, and it does work...

• Ubuntu won't use my nvidia driver

  - by Spencer

  I'm running Ubuntu 12.10 on a laptop that has both Intel Integrated Graphics and an Nvidia Geforce 540m. I installed the drivers properly, but I can't manage to actually use them. I'm stuck in 640x480 resolution and the drivers aren't detected anywhere. Each time I open the Nvidia settings menu it says: "You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (Just run 'nvidia-xconfig' as root), and restart the X server." ^Doing so does not help. Anybody have any ideas?

• xubuntu install on p4

  - by adi

  Hello i am thinking of installing xubuntu on a dell gx260 pentium 4 pc with: 1.8GHz processor 64mb integrated video card(had other but it died on me) 1GB of RAM Ive installed lubuntu but im not enjoying it since i can not make shortcuts of partitions or folders on desktop for faster usability(i dont want them on my bar, want them on desktop) also the buggs i seen on it made me reconsider of using lubuntu:mplayer not working, no video was working,chromium outdated etc and i dont want to stay all day to find solutions over the internet. And seen on internet from xubuntu that theyve had shortcuts for theyre partitions on desktop, and is more attractive.(can some1 tell me if with xubuntu u can make shortcuts on desktop, i mean the shortcuts remain after reboot) 1 more thing to add:at installing lubuntu when it asked me where to install it only showed me the entire hard drive(i have 3 partitions on it) and made me select the size of the lubuntu partition from 1 that the installer wanted.(from local disk D: from windows xp view),need to mention that i have windows xp on the machine which is on local C:, kept my downloads on local D:, and other stuff on E:. I want an ubuntu distro which would work fine especially for internet purpose. Can someone lend me a hand on this?

• How to hide bottom panel in GNOME?

  - by Bakhtiyor

  I want to hide bottom panel of Gnome in Ubuntu 10.10 so that I would be able to show it again when I want. In the property menu of the panel there is an option for Autohide but not hide totally. The reason I need it, is because I am using Docky panel and it now it is behind the bottom panel and looks like awful. What I am doing right now is I am deleting it totally by right clicking on the panel. And the only way I know to return it back is executing following command in the terminal. rm -r ~/.gconf/apps/panel Any other solutions?

• Replace Broadcom "wl" driver with "b43"

  - by Laszlo Boros

  I'm using Ubuntu 10.04.4 LTS, and in my laptop there is a Broadcom BCM4312 wlan card. lspci output: 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) Subsystem: Broadcom Corporation Device 04b5 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at f4500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number 81-ac-1d-ff-ff-12-54-92 Capabilities: [16c] Power Budgeting Kernel driver in use: wl Kernel modules: wl, ssb So as you can see, the current (and default) driver is wl - installed with jockey. But I have another Ubuntu based distribution on my laptop (BackTrack linux), which is also 10.04, but it has the b43 driver installed and the overall performance is MUCH better. So I would like to install it on this OS too, but even google didn't help me. So my question is how to install the latest b43 driver on my Ubuntu?

• Why does my display keep turning off every 10 minutes?

  - by George Edison

  I have installed Ubuntu 11.10 (Oneiric) in VirtualBox as well as virtualbox-guest-additions . The display resolution adapts to the size of the window as expected, but the display turns off after 10 minutes of inactivity. Thinking there was some sort of power management issue at play, I went to Power in the settings dialog: There doesn't really seem to be anything there that mentions "turn off display after xxx minutes" so I assume everything is configured correctly there. Next I went to Screen and found an option there "Turn off after:". Aha! I thought. Now I have found the option - but alas: even after setting it to "never" and restarting multiple times, the display still shuts off after 10 minutes. What am I missing? What option am I overlooking?

• How to create or recover Windows Bootloader after deleting Ubuntu boot drive

  - by Kincaid

  I have a computer that dual-boots (or tri-boots) Windows 8 Release Preview, Windows 7, and Ubuntu 12.04. Grub boots between Windows 8 and Ubuntu; for which I use primarily. Recently, I decided to remove Ubuntu, as I hardly used it. I deleted the Ubuntu partition accidentally before replacing the Grub bootloader. Now, whenever I want to boot the machine, it gives me the "grub-rescue" prompt -- I am unable to boot into either Windows (8 nor 7), nor Ubuntu (except via USB, of course). I do not have any Windows 7/8 recovery media, so that isn't an option. Please note that after I deleted the Ubuntu partition, I put the PC into hibernate, and then turned it on. This means the C:\ [Windows 8] drive cannot be mounted. I don't know if that is bad, but it definitely doesn't make things better. I am currently booting Ubuntu via USB, in an effort to restore the Windows bootloader. I have looked into using boot-repair to solve the problem using the instructions here, although after attempting to apply the changes, it gave the error: "Please install the [mbr] packages. Then try again." I don't know why I'm getting this error; is there a way to install the 'mbr packages?' I honestly don't know what exactly they are, nor how to install them. Are there any other options I have not yet exhausted to be able to boot back into Windows, in the case that there is a better way? I want to set the bootloader to boot into Windows 8, but booting into either Windows 7 or 8 is fine (I can use EasyBCD from there). Is there a simple solution to this? I've checked BIOS, and I haven't been able to find a way to boot into Windows.

• Is Ubuntu Touch a separate distribution or the same one?

  - by Nickolai Leschov

  I would like to install the latest Ubuntu Touch on a 2013 Nexus 7 tablet. Which version should I be looking for: the regular Ubuntu (for ARM platform) or a separate Ubuntu Touch? I understand that after Ubuntu Touch is in frantic development, but I would like to be able to keep track which one is which. I can see the following images: Ubuntu 14.09 RTM, daily-preinstalled Ubuntu Touch 14.10 (Utopic Unicorn) Daily Build Ubuntu 14.10 (Utopic Unicorn) Daily Build, but only i386 and amd64; no ARM. Does it mean that ARM variant has moved to one of the first two links?

• Lucid hangs at booting after kernel upgrade

  - by Thomas Deutsch

  This weekend, one of our servers running Lucid has installed some upgrades: libgcrypt11 1.4.4-5ubuntu2.1 linux-firmware 1.34.14 linux-image-2.6.32-41-generic 2.6.32-41.91 linux-libc-dev 2.6.32-41.91 Afterwards, it rebooted since this was a kernel upgrade. Now, it hangs at booting, after /scripts/init-bottom. init-bottom itself should not be the problem, the last line I can see is "done". So the problem has to be shortly after that. http://manpages.ubuntu.com/manpages/hardy/man8/initramfs-tools.8.html tells me, that the next step is procfs and sysfs are moved to the real rootfs and execution is turned over to the init binary which should now be found in the mounted rootfs. But I don't know how and where. The problem exists with older kernels too, and this one here doesn't fix the problem: http://www.tummy.com/journals/entries/jafo_20111003_160440 Anyone an idea?

• How do I record audio through M-Audio Keystudio?

  - by interstar

  Hi, I'm trying to get my M-Audio Keystudio (which has an audio input as well as the keyboard) to record audio to Audacity. I'm in Ubuntu 10.10. When I look at the Sound Preferences I can select "M-Audio RunTime DFU Analog Stereo" as my input device. However, when I try to record in Audacity, Audacity remains frozen. The program seems to be running and recording, but the recording cursor won't advance. If I reset the audio input to the internal sound card, recording works normally. Any ideas what to look for?
