• How to manage two video cards on a laptop (ATI and Intel)?

  - by Marc-François Cochaux-Laberge

  I have a laptop with two video cards. One ATI and on integrated Intel. On Windows, I can choose which video card I want to use. For example, I use the Intel card for normal use and for gaming, I switch to my ATI card for better performance, but a shorter battery life. In Ubuntu 10.10, only the Intel driver is installed, the ATI driver for my card doesn't work at all and there's heat coming out of my computer all the time, like when I'm playing video games on Windows. I think both cards are active, but only the Intel one is usefull. How can I solve this by making sure Ubuntu is aware of the two video cards and by disabling my ATI. Or may be I am all wrong about this?

• XUbuntu 12.04 sound becomes distorted on ASUS-computers

  - by Slava Fomin II

  On my XUbuntu 12.04 Desktop from time to time audio becomes distorted, not the audio from some specific applications but every possible sounds are very noisy and barely recognizable. Then i go to: Applications Menu Multimedia PulseAudio Volume Control "Configuration"-tab and change Built-in Audio's Profile from my current profile to something else. After that audio becomes normal, until it breaks again and i have to repeat these steps. It's happening on two different computers: one is an ASUS-based Desktop and other is ASUS notebook. Maybe it's related to some common motherboard audio components. Motherboard is: ASUS P8P67 EVO REV 3.0 Netbook is: ASUS EEPC VX6 Any help will be much appreciated = )

• Nokia Bluetooth headset Bh 503 not recognized

  - by euDennis

  I bought an Nokia Bluetooth Phone Bh 503. It works just fine with my Android phone, but with Ubuntu it even get recognized. I already paired the Ubuntu with my Android, but with the bluetooth phone it even find it. What can be the problem? Already search in Google for answers, but almost always the problem is with bluetooth that doesn't work, but in my case it works, but not with the headset. Already install almost all packages about bluetooth, like blueman, bluez, gnome-bluetooth, bluetooth, etc.

• Creating a bootable USB recovery drive to be used by someone who isn't computer savvy

  - by David

  I am looking for a way to prepare an image of an Ubuntu machine which would be bootable and installable in the easiest way possible. I'm actually preparing an Ubuntu machine for someone living far, and not computer savvy. If he ever has troubles with his installation, he could just put a USB drive in, boot the machine and everything would be resetted for him. I know there are many methods of creating/loading an image of a drive, but the ones I've found so far have complicated menus with several options to choose from, etc. Ideally, perhaps only asking a Yes/No question such as "Would you like to reinstall?" would be great. Does such a tool exist? Thank you in advance!

• How can I run samba?

  - by depesz

  I have server running Ubuntu 10.10. Never used samba before, as I never had windows machines, but now I need it. So I did: apt-get install samba smbfs smbclient. Packages are installed, but I have no idea how to configure it. All howtos I found on the net relate to /etc/samba/something.conf, where I don't even have /etc/samba directory. The only config I found is /etc/default/samba, which contains (aside from comments) only: RUN_MODE="daemons" All I want is to be able to have access to some directories on the Ubuntu machine from Windows, nothing else.

• What is the situation about OpenGL under Ubuntu Unity and Gnome3?

  - by user827992

  In a GNU/linux distribution is usually installed Xorg as main graphical server, it operates with a client-server logic, a special windows is designate as desktop environment and this special windows can handle all the eyecandy stuff like decorations, icons and effects. The problem is that the latest UI heavily relies on hardware acceleration, Unity is an overlay on Compiz and the Gnome-shell also require an active driver for the GPU to work well: the problem is: on the same OS I can find multiple implementations of OpenGL who is handling my OpenGL buffer? how the OpenGL buffer is managed compared to the other windows? how can I be sure that my OpenGL implementation is glued to the hardware and is not related to the client-server logic of Xorg? For example I have tried the clutter library and I have only experienced problems under both Unity and GTK/Gnome, no problem under other OS.

• Sharing samba-folder with root access

  - by Industrial

  Hi everyone, I have a staging server in my network running Ubuntu server 10.10, being my main development area. As I need to access the files in the Apache root from other computers in the network, I have setup samba with the following settings: [www] comment = Apache root www path = /var/www writable = yes force user = root force group = root On the host computer, running Ubuntu 10.10 desktop, I am trying to mount the drive with a bash file looking like below: #!/bin/bash sudo mount -t cifs //192.168.1.5/www /media/www/ -o username=myusername,password=mypassword,rw,iocharset=utf8,file_mode=0777,dir_mode=0777 What happens is that I get mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) thrown in my face whilst trying to execute the mount. I've done exactly the same, with exactly the same smb.conf & mount-bash file on another computer in my network, but this just wont work. What am I doing wrong? I am running out of ideas.

• How to force Empathy Internet Messaging to change default webcam?

  - by user43430

  I just recently bought a new webcam. It is USB powered. For personal reasons, I wish to not use the built in webcam that came with my netbook. I want to use this new one. I love empathy, it is a great chat client. But, I can't seem to switch my default webcam in empathy from the built in webcam, to the one I just bought. So, is there a way to force empathy to use the USB powered webcam, rather than the built in webcam?

• Is it possible to allow the user to access the 'Volumes' without asking the Administrator's password?

  - by Tom

  Am the administrator of my Ubuntu system. Recently I added a new user account. But when ever the user tries to access or open the 'Volumes'(Drives where movies, songs and other files are stored) it asks for the Administrator's password. I created the user account to my other family members and I don't want to tell them my password. So is it possible to allow them to access the Volumes without asking Administrator's password ? UPDATE : Ubuntu was installed alongside Windows in my system. I will provide a screenshot of the Volume details -

• dnsmasq not running

  - by Yevgeniy M.

  i installed ubuntu 12.04 on a netbook with 16GB SSD. To keep the installation small i used the mini.iso i got from here. Everything worked fine, but i noticed that dnsmasq does not get started by NetworkManager. On a different machine i installed 12.04 from a regular iso and netstat shows dnsmasq running and listening on port 53. NetworkManager.conf look identically on both systems. The line dns=dnsmasq is present. Although i do not really need dnsmasq - name resolution works fine without - i would like to know the reason why dnsmasq is running on one system, but does not run on the other and how i could adjust this behavior. Thx in advance!

• Dual monitor setup with Intel graphics and Nvidia Geforce GT 425M on 12.04

  - by fo_x86

  I have a Dell XPS L401x and just installed 12.04. I have a mini-display and an HDMI output, and I could hook up two Dell UltraSharp monitors to each port on Windows 7, and get a triple monitor setup. Doing a bit of research, it seems like the mini-display is wired to the integrated graphics card whereas HDMI is hooked up to Nvidia graphics card. I've also installed Bumblebee as it seemed like that was the proper way of installing Nvidia drivers on Ubuntu. At the moment none of my monitors is being recognized by Ubuntu. Is it even possible to have a triple monitor (laptop display + 2 external) setup? Has anyone successfully done this?

• Sharing a mounted Truecrypt volume via Samba

  - by user10492

  Been banging my head against the wall on this one for a while. I have an encrypted (via truecrypt) partition on a drive. In windows, I mount it locally and share it on my local network. I'm trying to do the same in Ubuntu 10.10 but am running into permission issues. The tc volume has funny permissions and I just can't seem to figure out a way to access it (unsecurely of course) over my network. Other non-tc volume shares work just fine. To recap, I mount a truecrypt volume in Ubuntu and set up a samba share as normal. The share shows up on my local network but accessing it gives 'permission denied'. Mounting as a network drive using a password does not seem to work either. Any insight would be greatly appreciated.

• Cursor freezes for 5 secs every now and then

  - by user20560

  I've installed Ubuntu 11.04 (64bit) on my new Thinkpad Edge 11 laptop from Lenovo with the following specs: Processor type AMD Athlon II Neo Processor Speed 1.8 GHz Memory Type DDR3 SDRAM RAM 2048 MB Hard Drive Type HDD Harddisk 250 GB Grafic processor ATI Mobility Radeon HD 6310 Ubuntu has found all my hardware and it works perfectly. I have one irritating problem though: From time to time (sometimes every minute, other times every hour)the cursor freezes for about 5 sec. This happens independently from the number of processes running on the laptop. It's only the cursor that freezes - I can still tab between windows and use the keyboard. I've installed GPointingDeviceSettings, activating the trackpoint, which btw works perfectly. Also I have installed the ATI Catalyst proprietary display driver. Anyone has an idea of whats wrong? Thank you in advance Best regards, Jens

• What's the right terminology for Unity's UI elements?

  - by Bou

  Hi, I've sent a few mails to the Ayatana mailing list regarding some UI suggestions for Unity, but I'm afraid I keep confusing the right terms for the UI element, so I would like to have some clarification. Is the bar at the top called "panel"? Does the Ubuntu logo at the top left corner have a name? Is the left sidebar called "dock"? Are the coloured tiles with app icons on them called "launchers"? Is the purple tile called "workspace switcher"? Are the fullscreen things that appear when you click the Ubuntu logo, the Places tile or the Apps tile, called "dash"? Do they all have the same name?

• Update drivers for TL-WN851ND

  - by Tony_GPR

  Today I bought a new PCI wireless card, TP-Link WN851ND, with Atheros AR9227 chipset. It has 2 antennas and is compatible with Wifi N so I thought it would improve the quality of the signal. But after install it on my computer the result is the opposite to expected. It doesn't connect to my network, while my old Wifi BG card connect without problems, I created an access point from my smartphone to try the card, and work, but is very slow loading pages. In Windows 7 works perfectly, so I think the problem is the driver. I have Ubuntu 12.04 LTS with kernel 3.2.0.31, is there a way to update the driver or I can apply a patch to improve the performance of the card? Otherwise, anyone know if there is a work in progress to improve compatibility with this chipset, or is it better to change the card and buy one with better driver compatibility. And finally, which wireless N compatible chipsets have good support under Linux/Ubuntu?

• All video thumbnails fail to be generated

  - by Forage

  Not a single video thumbnail is being generated and shown in Nautilus. The folder ~/.cache/thumbnails/fail/gnome-thumbnail-factory/ keeps getting filled for all of them. I tried removing all the thumbnails from the folder, reinstalling the gstreamer-plugins-... and totem packages, changing the thumbnail settings (Always, 4 GB) in the Preview section of the Nautilus preferences. All to no avail. Some recommend to install packages like libxine1 and ffmpegthumbnailer but this didn't not solve it either. There used to be an .xsession-errors error log file generated in the home folder in previous version of Ubuntu but that doesn't seem to be the case any more. I'm running Ubuntu 12.10 GNOME remix (x64) with the GNOME3 ppa packages installed. What could be the cause of the problem and how can I fix it?

• Lost the Hard Drive Icon from the Launcher

  - by Elbe

  I unlocked the C Drive icon connected to the Launcher. Once I moved it onto the desktop, it disappeared. In attempting to create an new icon, I was asked to create a mount point. The mount point directory then showed 2 links rather than the normal 1. I trolled the web for solutions, but I did not find one that addressed any of the stated issues. I attempted to find a solution to reconstruct the hard drives that were found during the install and listed in the Launcher but was unsuccessful in doing so. In summary, I would like to restore the /media directory to the original install which listed the drives correctly and have the drive icons appear in the Launcher as they did at the time of the installation of Ubuntu. I found where all the other icons in the Launcher located in the home Desktop directory but could not find anything that listed the hard drives or the floppy. Ubuntu 12.10 is installed and all the latest updates have been applied.

• Black bars around screen? Catalyst Control Center problem?

  - by Josh B

  I just newly install Ubuntu 12.04, and im running an HDMI cable from my computer to my ASUS monitor. Now in Windows 7, i did not have these black bar issues running at 1080p. But now in Ubuntu, i have these black bars. I installed the ATI Catalyst Control Center, and I went to go in to fix the scaling but it is grayed out. As you can see, even with the override box checked i still can not set the scaling. The monitor was set to a lower resolution to hopefully fix it but that did not work either. Does anyone know how to fix this? Thanks.

• I want to learn how to help or contribute to Unity

  - by user17953

  I am a college student studying computer science and would one day like to work on operating systems. The part of ubuntu that really interests me is Unity and I would like to study it and possibly contribute to it. I was reading the wiki pages about it and it was saying to get a copy of all the required components and then start hacking. Would it be wise to do this in a virtual machine with ubuntu on it? Do you have any advice on a good place to start? Do you know of any common pitfalls? Should I also post in the irc for this? Thanks

• How do I get my Broadcom BCM4313 working correctly?

  - by Ataraxio Panzetta

  I've installed ubuntu on a Asus 1015 netbook. Everything worked out of the box except for the Wireless adapter, which i had to install with the Additional Drivers application. It apparently installed fine and connects to our wireless network, but it only works at a "funny" speed range that goes from 367Bytes to a peak of 3Kb in its best moments. I know for sure the problem is neither the network nor the hardware. Network speeds are normal under windows on this laptop and in other computers with ubuntu aswell. lspci says the card is a BCM4313 model, but the Addittional Drivers Manager says these packecege contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322 based hardware seems like it installed the wrong driver... Is there anything I can do? I'm not concerned about compiling the driver or stuff like that, but I'm not sure on where to start... any help or guidance will be very, very appreciated.

• How do I reopen an instance window once it has disappeared from desktop?

  - by Mohamad

  I'm new to Ubuntu. I use Skype and often the main window just disappears from my desktop. The Skype instance itself is still running in the background. I know this because I can see its notifications on the bottom right side of the screen. If I click on the Skype icon again, Ubuntu will launch a new instance instead of maximizing the running instance. Of course this will not work because Skype will not let you sign in: Another instance of Skype may be running. How do I refocus/bring to the foreground the existing Skype instance? In Windows, you can restore running instances through the taskbar. I've tried cycling through open windows, but the running instance window is no where to be seen.
