• Purple Screen then Black Screen while Booting from CD or Windows Install

  - by Tyler

  Whenever I try to run Ubuntu from my internal CD drive, I see this screen minus the Ubuntu Text: Then the screen goes black, not even the internal light stays on. Sometimes it restarts itself, other times the black screen is indefinite until I restart the laptop myself. I'm on an HP Quad-Core AMD A8-3500M APU with 8 GB RAM and a Radeon AMD 6620g Discrete-Graphics Card. (HP dv6-6145dx) This is my first time using Linux, I am not too technically-inclined so any simplification would be welcomed. I am good at following technical instructions though which is how I was able to partition my hard drive and change the boot order to allow the internal CD drive first. Thanks in advance!

• Black & White Video with Youtube

  - by RobertPitt

  Hey'a guys, I have an issue with the Youtube Player within Ubuntu, it seems that when playing videos there in black & white, no matter if there normal or HD. I kind of figured out how to prevent this from happening by deleting the cookie PREF that holds a KV Pair like so: PREF f1=50000000&fv=10.2.154 .youtube.com / Sat, 12 Mar 2011 11:38:29 GMT The issue is the Flash Version key, when I Delete this the color comes back, but obviously when I navigate to another page the cookie is set again. Does anyone know why this issue occurs and a possible fix? Using Latest Google Chrome on the latest version of Ubuntu (Installed 3 days ago) Thanks

• Skipping video and audio with PS3MediaServer

  - by MaxMackie

  I'm using the latest PS3MediaServer build right from the repos suggested in the Ubuntu Wiki. I'm streaming multiple movies from my server (Ubuntu 10.04 LTS) to my PS3 over wireless. Sometimes, during some movies, the audio and the video will begin skipping. This can last anywhere between 5 and 30 seconds before it goes back to normal. I have a four core i5 processor and 8GB of DDR3 RAM so I don't think my computer is having a hard time keeping up with the transcoding. So this leads me to believe it's either sub-optimal transcoding options from within PS3MS or my network can't handle the heat. Other than the out-of-box configuration, is there any way I can tweak the settings for the application to use my resources more efficiently?

• 12.04 - Connecting Acer X203H monitor to new Dell XPS 15z laptop

  - by Lucy Dixon

  I have installed the latest version of Ubuntu (12.04) on my boyfriend's new Dell XPS 15z laptop. He uses a Microsoft wireless keyboard and mouse, and an Acer X203H monitor with his set-up. No problems with the keyboard or mouse, or with connecting the HP printer, but we just can't get the laptop to talk to the Acer monitor. With his old setup he used a VGA cable to connect machine & monitor. New laptop has no VGA port, but we've bought a VGA to HDMI adaptor to connect to the laptop. Have tried using Fn F2 to change the display from laptop to monitor, but it doesn't see the monitor at all. HELP! Is there a driver I can install from somewhere? Or how can I tell Ubuntu to look for the monitor on another port? Completely in the dark, and about to get in trouble!! Thanks

• Does the Wacom Bamboo Pen & Touch work out of the box?

  - by Emilien

  Is there any tweaking involved in Ubuntu 10.10 to make the Wacom Bamboo Pen & Touch work? And is this hardware getting some love from the new multitouch framework? If there's no multitouch support for it, then I'd fall back on the simpler (and cheaper) Wacom Bamboo Pen (to draw, no multitouch)... ENAC's general list of Linux multitouch devices states the following regarding Wacom: "The 'wacom' kernel driver handles these, and is undergoing work to make it compliant with the kernel multitouch protocol." But is this also compatible with Ubuntu's multitouch protocol (which I understand is a different effort than the kernel's)

• How do I list installed software with the installed size?

  - by Lewis Goddard

  I would like to have a list the installed software on my machine, with the disk space consumed by them alongside. I would prefer to be able to order by largest/smallest, but that is not a necessity. I am the sort of person who will install software to try it, and never clean up after myself. As a result, my 7GB (Windows and my Data are on separate partitions, as well as a swap area) Ubuntu 11.04 partition is suffering, and has started regularly showing warning messages. I have cleaned my browser cache, as well as everything under Package Cleaner in Ubuntu Tweak, and am left with 149.81 MB off free space.

• How can I add the softwares I have installed from USC of kubuntu 12.04 into kubuntu 12.10 iso installation file

  - by Suhail cholassery

  I am currently using Kubuntu 12.04. I don't have strong high speed Internet connection and managed to get Kubuntu 12.10. I found that it's size is about 1GB. I have a lot of softwares installed in my current Kubuntu 12.04 via Ubuntu Software Center I would like to Add these software to Kubuntu 12.10 installation iso file. I don't want to download packages from Ubuntu customization kit (UCK) or similar software. I don't prefer using APTonCD or similar software. What I want is to add these software into this Kubuntu 12.10, so that they appear along with the default application which will be installed as default when the OS is installed. Is this possible?

• Wifi hotspot to connect to Android using non-AP supported cards

  - by 3l4ng

  I'm running Ubuntu 13.10 64b on a Dell Inspiron N5010. My wireless device (found using lspci) is Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01). I bought a new android phone and want to connect to Internet by using the laptop as a Wireless Access Point (ad-hoc doesn't work with Android). I tried following tutorials like the one at How to setup a wi-fi hotspot (access point mode)?. The relevant output from iw list was Supported interface modes: * IBSS * managed Running sudo hostapd /path/to/conf/file gave me (eth1 is the wireless, verified by iwconfig) Failed to create interface mon.eth1: -95 (Operation not supported) Could not set channel for kernel driver eth1: Unable to setup interface. Could not connect to kernel driver. I am able to use Connectify and Virtualrouter on Windows, and the phone works great. How do I get an access point running on Ubuntu? I'm open to other alternatives as well.

• Installing gdm on headless Server Edition

  - by Andrew Koester

  I have Ubuntu Server running on a headless box, which is right now, almost entirely doing only software RAID and feels a little underused. I'd like to get into using Ubuntu as a desktop a little more. What do I need to do (install/etc.) to get Gnome while keeping the box itself headless? I'm not sure which packages to install or which steps to take. I figure I'll just use X over the network (Xming or the like) but something like NX might work.

• Are there any plans to create a standard based on libunity?

  - by Sebastian Billaudelle

  In the last few month and maybe even years, Ubuntu and Canonical often were criticised for developing software and desktop components without talking to other groups in the free software community. I don't want to comment on this topic, but I see problems arising with creating a "proprietary" solution for displaying indicators and progressbars with a launcher like Unity. In the world of free and open Desktop Environments we often try to standardize parts and libraries or write specifications to increase collaboration between different desktops. We have the instrument of http://freedesktop.org and a lot of specifications are getting implemented by the major Desktop Environments. In this context, proposing a standard for those indicators would be a great step towards better interoperability between desktops. These indicators represent a great feature on the Linux Desktop and I'm sure that other projects like AWN, Docky, etc. would pick them up. With the great market share of Ubuntu, Canonical is in a position to propose it as a standard and encourage projects to implement it. Thank you in advance, Sebastian Billaudelle

• WD external hard drive not detected

  - by Khang Nguyen

  I am a beginner in Ubuntu. And I have just installed Ubuntu 11.10 in my Dell laptop. When I plugged my WD external hard drive in, it read the first time, but since I have a unlock.exe file (password for the hard drive). So I installed Wine to read it. But it gives me an error. I restart the machine, and plugged the hard drive in again. And it is not recognized anymore. Can anybody help me, please? Thank you!

• Change permission for ALL folders and files

  - by Xweque

  I've been around Ubuntu for not too long now and I'm getting tired of a thing I used to accept. When I installed Apache and PHP on Ubuntu it was done with root meaning it got permission. So I changed that to me. Now I've just copied a big number of files, (PHP), to be viewed and edited in these directories. Now my problem: I can not view the files from var/www/ because it requires, for some reason, everyone to have access to the files. Not only me, or my group but everyone. No one else is using the computer but me, so I'm cool with it. Though I need a command to change ALL files permission recursively. When I've browsed the questions already been answered I find for example chown -R viktor:viktor /var/www/, or using sudo as well. This worked on the single var/www and the folders inside but not the files inside the folders and very odd I notice I can't do the same thing on example /var/www/dev/.

• Converting a video file in arbitrary file format into MPEG4/H.264?

  - by knorv

  I want to convert a large number of video files in various formats into .mp4 files (container MPEG-4, codec H.264). I want to do this on an Ubuntu machine, using only command-line tools and I'm willing to install packages from main, restricted, universe and multiverse. Ideally I'd like to be able to do ... for VIDEO_FILE in *; do some_conversion_program $VIDEO_FILE $VIDEO_FILE.mp4 done ... and have all my video files in .mp4 format with container MPEG-4 and codec H.264. How would you tackle this problem on an Ubuntu machine? What packages do I need to install?

• Nautilus will not launch after update to 12.10

  - by dereksalerno

  I updated to Ubuntu 12.10 today from 12.04 using the graphical update tool. Everything seemed to be fine until I went to open Nautilus, and it would not open. Bizarrely, I am able to open a file that I happen to have on my desktop, but when I click on the launcher, it never opens. When I enter 'nautilus' in the terminal, I get this: (nautilus:8557): Gdk-CRITICAL **: gdk_x11_display_get_xdisplay: assertion `GDK_IS_DISPLAY (display)' failed zsh: segmentation fault (core dumped) nautilus I am not a total novice with ubuntu or linux, but all I can tell is that there is some problem with X. Can someone please point me in the right direction as far as fixing this? I really don't want to have to do a fresh install. Thank you very much.

• Bumblebee - Poor performance with games

  - by user106880

  I have an Alienware M14x (GeForce 650m with Optimus) and got Bumblebee working correctly (trying to get ready for steam for linux :)). Also I'm running Ubuntu 12.10 with Unity. I get great framerates with glxgears and sauerbraten (a game on the repositories), but when I run games like Bastion and Splice, I get pretty terrible framerate, in fact worse than my integrated intel gpu. I have nvidia-current installed under ubuntu-x-swat/x-updates so it's driver version 310.xx. Also I forgot to add that I haven't been able to test other drivers because they seem to break glx (x can't load the glx module). I've been troubleshooting this for days now, and I'm very nearly out of ideas. Any hints on why only some games are running so poorly with bumblebee?

• How to use the AccountsService API with Python?

  - by pabluk

  I'm writing an application for the Ubuntu app showdown and I try to read/write the user's profile picture using this >>> from gi.repository import AccountsService, GLib >>> current_user = GLib.get_user_name() >>> user = AccountsService.UserManager.get_default().get_user(current_user) >>> print user.get_icon_file() None >>> print user.get_user_name() None But apparently does not work. Is there another way to use AccountsService with Python? I could not find more documentation about AccountsService and Python. PS: to test this example you need to install gir1.2-accountsservice-1.0 on Ubuntu 12.04. $ sudo apt-get install gir1.2-accountsservice-1.0

• Install packages with unmet dependencies

  Hi all, I am trying to install some applications but some of them fail to install. The three applications I tried are Vim, Emacs and GNOME-Do. I am using Ubuntu 10.10 installed as a guest OS in VirtualBox. The kernel version installed is 2.6.35-26. The error I got is : alvinsim@ubuntu:/etc/apt$ sudo apt-get install emacs Reading package lists... Done Building dependency tree Reading state information...

This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: emacs : Depends: emacs23 or emacs23-lucid but it is not going to be installed emacs23-nox but it is not going to be installed E: Broken packages What is wrong and how do I fix this?

• Cannot boot from USB disk with "not a COM32R image" error

  - by Siva Prasad Varma

  After installing 11.10 on my Dell Studo 15 (Model 1557) laptop, it started to overheat. Recently it even shutdown twice saying that critical temperature has reached even when I was just idling (not even a single program was open except for Firefox). After learning that it is a problem with 3.0.0 kernel I decided to roll back to 10.04 LTS. I have downloaded the most recent 10.04 iso from ubuntu.com and created a live USB using startup disk creator in 11.10. But when I am trying to boot from USB I am getting the following error vesamenu.c32: not a COM32R image I have installed ubuntu from usb stick a couple of dozen times before this and I think it is not a problem with my hardware. Please tell me what to do.
