• How to make Bluetooth headset appear as a sound device?

  - by torbengb

  I have an onboard VIA sound card but no speakers attached. Instead, I want to use my bluetooth headset as my only sound device, both input and output (mono). I plugged in the bt dongle and was impressed that it was ready to use within seconds. I then paired it to my Jabra BT500 headset. No problems so far. I then went to Sound Preferences but no bluetooth is listed, only the onboard VIA sound card. Question: How can I enable my headset, and make it the default all the time?

• USB modem could not mount on 12.04

  - by maz

  I have a usb wimax modem. If I connect it at ubuntu 10.04 it has been detected and mounted as cd see here. From there I got that it is "iso96660" type and device location is /dev/sr1. But when I connect this usb modem in Ubuntu 12.04, it could not be mounted. So I have tried to find the file sr1 in this location /dev/ and could not found any-thing. But if disconnect and then re-connect the usb modem at this path /dev/, I saw a flickering of "sr1" named file for a certain time (1 sec) then it's dis-appear. Can anyone guide me to connect it step-by-step in Ubuntu 12.04?

• Are there "portable" versions of Opera for Linux/Ubuntu?

  - by cipricus

  I want to use the latest Opera browser, but v12 does not have opera-unite anymore. So, I would like to use a "portable" v11 Opera (v11 has unite). (By portable I mean a program with all files within a certain directory that can be put in any place on the hard drive or on an external drive, a program that can be started by running an executable file from the same directory, and which can be run separately of other installed versions of the same program.)

• KDE's Dolphin Can't See Connected devices such as Nikon, Canon Cameras

  - by Swapnil

  I have noticed this problem across all distros including Kubuntu and openSUSE. Many times my Nikon D 7000 and Canon HF 11 are not seen or mounted by Dolphin. When I connect the Cameras I don't get any notification in the tray which otherwise shows connected device. Ironically when I open Nautilus then I can clearly see the cameras mounted. I also have a request that what these devices don't appear on Dolphin's side panel automatically. It makes life easier for a users. https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/956806/+attachment/2879913/+files/dolphin.png

• Ubuntu 12.04 shut down freezes

  - by sam

  I am using Ubuntu 12.04 for last one month without any problem. It was upgraded from Ubuntu 10.10. Recently I needed to replace my hard disk. After replacement I installed Windows 7 and Ubuntu 12.04 on the system. For some days it went ok, but now shutting down from Ubuntu is causing problems. It freezes on the text screen saying acpid=exiting checking for running unattended upgrades. After that I waited for a long time, but it didn't go off and I had to hit ctrl+alt+del to restart the system and booting from Windows and then shutting down from there. This happens every time I shut down my system from Ubuntu. I have seen many posts regarding the same kind of issues but none of the solutions reported there helped me out.

• Create a custom shortcut that types clipboard contents

  - by briankb

  I want to paste my clipboard contents to a remote session such as VNC, IPMI, or Raritan. To accomplish this, I installed xdotool and clip. Then I wrote a simple command that types the clipboard contents: xdotool type "$(xclip -o)" This works if I stay in a terminal window, and type that command myself. It types back my clipboard contents when I run the command. Of course now I want to make this into a hotkey that works in any window. However, if I create a custom shortcut using Keyboard settings, it doesn't work. If I assign a hotkey Alt+K to the shortcut, nothing happens when I press it. If I use Ctrl+K, unexpected behavior occurs to whatever window has focus. e.g. my terminal window size shrinks (it's somewhat amusing, actually). Similar results occur if I save it as a script and call the script, or if I encapsulate the command with sh -c. How can I make practical use of the powerful xdotool type command?

• Wireless not connecting on Ubuntu 13.10, Toshiba Satellite pro L 650

  - by user204842

  I have just installed Ubuntu 13.10 on my Toshiba Satellite Pro L650. After several reboots, installing/ uninstalling the broadcom driver I still can't connect. It detects the wi fi signals and the icon flashes as if it's trying to connect but never actually does. I'm really quite rubbish with code and stuff, but I really like Ubuntu as an OS and would really appreciate any suggestions anyone can offer! 02:00.0 Ethernet controller: Qualcomm Atheros AR8151 v1.0 Gigabit Ethernet (rev c0) 03:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)

• What does 'Lock Version' do?

  - by richzilla

  Having installed an experimental version of dropbox and installed in manually, i dont want the deb in synaptic to download any updates (as theyll over write the changes ive done manually i assume). Ive found the lock version option in synaptic, im assuming this stops a particular deb from downloading any new versions of itself? Also can i just unlock it again when the version from the deb catches up with the experimental version that i have installed? Am i correct or does it serve another function?

• Where does node.js install to?

  - by Ash Scott

  I'm trying to install a script, which is a clone of a game, and uses node.js for it. Now, the documentation says I should copy the node.exe (windows) and put it where the clone is. Now, I can't find the node.exe ubuntu equivalent, I can't even find where it's installed?! Don't really want this hosted on a windows machine due to licensing. Here's a snipet from the doc: Download : Node.js (Install Button) Go where you are install Node.js (For Windows 8 it's C:/Programms/nodejs) Copy node.exe and paste on the clone folder Now I need to do this in ubuntu, however I can't find where node is installed to? Any ideas?

• Numbers on the launcher

  - by pete of ebor

  Using 12.04 LTS - few days ago, I left my machine on while I went out. On my return, the launcher was showing (it is set to be hidden) and there were small numbers 1-9 on the icons and letters s on the bottom-most icon and t on the rubbish bin. System still worked fine, although the launcher remained visible, and would not hide. After about 20 mins work, they suddenly vanished and the launcher hid itself.. is this a normal action ? It hasn't happened since..

• Applications Menu disappeared [closed]

  - by Sophie Sperner

  Possible Duplicate: Applications Menu disappeared I'm using Ubuntu 12.04, classic desktop without effects. Once the indicator-applet-complete (right part of the top panel) had disappeared. I found how to fix it: Alt-Win-RightMouseClick on the panel, then "Add to the Panel", where choose "Indicator Applet Complete" to add. Now, the left part of the top panel (Applications Menu) has disappeared! If I do Alt-Win-RightMouseClick on the panel, I can add only individual Menu sections like Internet, Office, Settings etc. But how to get back the full Menu as it ought to be?

• Ubuntu always freezes on a friend's machine

  - by missingfaktor

  I am posting this on my friend's behalf. I installed Ubuntu 12.04 on my friend's computer but it continuously froze, no desktop effects worked, and it was frankly unusable. I thought this might be an issue with Unity and how it interacts with his hardware, so I tried several other desktop environments on his machine. These include KDE, Xfce, and GNOME. The problems persisted regardless of the desktop environment. I would like to note that he dual boots his system with Windows 7. Even there no desktop effects work but the system is reasonably stable. The following screenshots describe some of his system information (He is running Xfce at this time): 1: 2: Card information: intel corporation 82G33/G31 integrated graphics controller (rev02). What is the issue and how can it be solved? Please let me know if I should add any more information. Thank you.

• How do I make my monitors show up as two separate monitors? - NVidia GeForce GTX 550 ti

  - by BriGuy92

  I've got a dual-monitor setup, with the monitors configured through the "Nvidia X Server Settings" application. In the Ubuntu Display settings, the monitors show up as one extra-wide monitor labelled "Laptop". Until now, this really hasn't been a problem, but now I'm trying to set up a Wacom tablet. The Ubuntu tablet settings allow the tablet to be mapped to a specific monitor, but since the OS "thinks" that I have only one monitor, I can only map the tablet to both of them. This is a problem. Is there any way to have Ubuntu recognize the monitors separately?

• How do I stop that launcher from popping up when mouse goes to the left edge?

  - by Michael

  This is what it says on the help.ubuntu.com website, but when i go to system settings, it does not have a Launcher & Menus option. I wish I could revert back to the old Ubuntu, I hate this launcher. Does any know a fix plz? "Stop the launcher from showing when I point to the left side of the screen The launcher unhides when you move your mouse or touchpad pointer to the left side of the screen. If you prefer, you can tell Unity to only show the launcher when you click the top left Ubuntu button instead. Click the icon at the very right of the top bar and select System Settings. In the Personal section, click Launcher & Menus. Choose Touches the top left corner of the screen"

• Facebook video is too choppy to watch.

  - by Greg Pauline

  Using firefox and chrome on an Acer Aspire 5100 with an AMD Turion 64 MK36 processor with 2GB of RAM and an ATI Radeon Xpress 110 Graphics card. I had a problem viewing Vimeo and youtube that has now been resolved with the help of this website. But now I find that trying to watch Facebook videos from family and friends is impossible due to the terrible choppy frame rate and near freezing of the browser window. Any idea what is going on and how to fix it?

• Skype no sound on Kubuntu 13.10

  - by Michael Aquilina

  I just performed a fresh install of Kubuntu 13.10 on my machine. Everything is working great except for Skype. I cannot get any form of audio playback in Skype. In the sound settings panel I get a bunch of different sound sources, none of which work! At the moment I have set it to "sysdefault (unknown)" I installed it using the deb package found on the official website. My phonon backend is using phonon-gstreamer. When running skype from the terminal I get the following error messages: ALSA lib control.c:953:(snd_ctl_open_noupdate) Invalid CTL plughw:CARD=PCH ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave Is this a known problem or has anyone experienced the problem and managed to solve it?

• Random freezes on MBP9,2 + Ubuntu 12.04

  - by EnToutCas

  I have a MBP9,2 (mid-2012) at work. I put Ubuntu 12.04 on it after some efforts. Everything works more or less now, except I get random freezing every now and then. I have to power off the machine to restore it. Wondering if anyone had the similar issue. My setup: MacBook Pro 9,2 (mid 2012) Ubuntu 12.04 (installed using the special image for Macs) No proprietary drivers xmonad on Unity 2D So far the freezes look to be sporadic and spontaneous.

• Ubuntu 12.10 live-usb won't boot

  - by user109175

  I own an Aleutia "Tango" low power PC. It uses a Intel Atom CPU N2800 @1.86GHz processor. I know there are Linux issues with the "Cedar Trail" graphics on this hardware but I can happily run Ubuntu 12.04 using the VESA graphics driver. I wanted to try out Ubuntu 12.10 so I created a live USB under 12.04 but I am unable to get this to boot. It gets as far as the Grub screen but after that the monitor shuts down. I have tried the F6 "nomodeset" option but that doesn't make any difference. Does anyone have any knowledge of this problem? Thanks in advance.

• How can I make KDE faster in Ubuntu 12.04. It's very slow

  - by Rizwan Rifan

  I installed the kubuntu-desktop package in Ubuntu 12.04 LTS, but the problem is KDE responses very slowly. If I click on an application's icon to run it, it appears after 10 seconds and sometimes does not appear at all. It hangs all the time. The cursor is almost impossible to follow because of the lag. I have read on the Internet that Unity uses more memory and CPU than KDE. But on my PC Unity runs smoothly and KDE does not. So what should I do to make KDE as fast, responsive and smooth as Unity? My specifications are as follows: RAM: 1.5 GB (DDR2) Processor: 3 GHz Dual Core Graphics Card: Intel HD graphics with 256 MB memory.

• wkhtmltopdf displaying text as blocks

  - by making3

  We're using wkhtmltopdf in a web project (nodejs/compoundjs). We've gotten it working how we wanted on our machines (using the --use-xserver switch). However, when I try to run this on our Ubuntu server 12.04 (without the ubuntu-desktop package), the PDF cannot use the switch. When we disable the switch, the PDF displays any characters as blocks (image below). How do I resolve this without installing ubuntu-desktop and running x server? I've found liberation fonts, which installing ttf-liberation and fonts-liberation did not help. And urw-fonts, but I have yet to find an Ubuntu equivalent. EDIT: It just hit me, this doesn't matter if I'm on the server or not. On my development machine (Ubuntu 13.04 desktop), I can run the following, which produces the same blocks: wkhtmltopdf http://google.com google1.pdf While this prints out the pdf properly: wkhtmltopdf --use-xserver http://google.com google2.pdf My version of wkhtmltopdf is 0.12.0.

• Why is bzip2 needed in the kernel patch instructions?

  - by user12657

  This was from here. Extract the patch tar -xvzf /usr/src/web100-2.5.22-200810130047.tar.gz bzip2 web100/ web100-2.6.27-2.5.22-200810130047.patch Test the patch bzip2 -dc /usr/src/linux/web100/ web100-2.6.27-2.5.22-200810130047.patch.bz2 | patch -p1 --dry-run I looked at the .patch, the diff output of many files and the file .patch.bz2 after the bzip2 command which is too also the diff output of many files, they seem to be the same. My question is why is bzip2 even needed to turn the .patch into a .patch.bz2? Is it for the redirection to std output from the -dc option for the patch command? Even if it is, why not just not just use the patch command in the form something like this:patch -p1 < patchfile? I don't see why the bzip2 is done here. Also, I think the bzip2 might have an extra space in the command after web100/, right?
