• Ubuntu 12.04 very slow on samsung netbook

  - by vallllll

  I have a samsung netbook n150 1Gb Ram (Intel graphic card), 1,66GHz Intel Atom processor. It was working great with the ubuntu 10.04 netbook edition, really fast boot very eficient but I have updated to 12.04 (the netbook edition doesn't exist anymore) and now the system is so slow: slow boot, sometimes it doesn't even boot properly, strange screen light on and off behaviour, when you click on an icon takes for ever to open the app even the terminal it takes like more than 10s! It seems that this new distro was made for a far more powerful systems than this netbook. I am considering to revert back to 10.04 or choose another linux distro but is there anythhing i can do to fix these problems? Any body else had similar problems. Thanks in advance

• How to fix LibreOffice 3.5 to start from launcher icon?

  - by Bucic

  Recently I installed LibreOffice 3.5 from debs (including the ones for desktop integration. Since then it behaves in a weird manner. Basically it won't launch from launcher shortcuts. Example: dash libreoffice launched (launcher shows with 2 seconds delay) 'keep in launcher' LO closed the LO icon on the launcher clicked pulsating for 5 seconds, then stops LO didn't launch I didn't look for open processes or anything and... dash libreoffice launched immediately without problems It also didn't remember recently opened items, but now it got fixed somehow. Other symptoms: - icon on the launcher and all menu categories appear with a delay of few seconds - two writer icons appear on the launcher What I did: used 3.4.5, uninstalled, installed 3.5 RC3, problems started to occur uninstalled RC3 'clean' per http://wiki.documentfoundation.org/Installing_LibreOffice_on_Linux#Debian_.2F_Ubuntu_3 installed 3.5 stable which is identical to RC3 still same issues I don't know if it is related but I use Unity test PPA:vanvugt/unity which I needed to solve the stuttering windows bug. Any ideas?

• What is the formal definition of a meta package?

  - by kojiro

  There are several examples of packaging where an application package is built, named, described, even licensed, but contains only setup code and dependencies -- it has no first-class runtime software of its own. I would call this "meta-packaging". This seems to be particularly popular in the open-source world, including examples like kde-meta (Gentoo Portage), Plone, and I'm sure lots of others. I can see how it's a useful practice, but despite it existing as a practice, I couldn't find a formal definition of either "meta-packaging" or "meta-egg" (Python) in searching the web. Is that not the correct term? If it is, is it such common-sense that it needs no formal definition? If not, what is the correct way to put it?

• Canon MP280 All in One prints but scanner not recognized

  - by Chris

  I recently installed Ubuntu 12.04 LTS after not using any Linux distro for several years. My Canon MP280 worked perfectly as far as printing goes and I was even able to set it up on a Samba share and print from a Windows 7 machine. However when I open Simple Scan it does not detect a scanner. I did find some instructions online but the scanner is still not recognized in Simple Scan even after installing a couple .deb packages from the Canon site. I also couldn't seem to find the ScanGear package after installing those .deb packages as well but I haven't had a chance to delve fully into it. Thanks for your time!

• No sound after clean install

  - by John Cheednik

  Did a clean install of Ubuntu 12.10 and everything working great except for the sound. Ubuntu doesn't even seem to be recognizing the fact my HP dv6000 has the capability of making sound! I have the dummy output problem, and when I try to open alsamixer using terminal I get the message that no such file or directory exists. I can't get it to recognize any soundcards or audio devices at all. I've been working on the problem for a couple days now and have even taken the laptop apart to ensure that all cables are properly attached... When I go into the PhoenixBIOS there are no sound options that I can find. The laptop does make a loud beep if I press buttons in the BIOS, but once it boots to the hard drive, the thing is mute. HELP!

• tty1 prompt before lightdm

  - by David Weldon

  After upgrading to 13.10, every time I boot I'm shown a login prompt (tty1) for ~30 seconds before lightdm automatically starts. Everything works fine after that. Any ideas on what I could try to fix/debug this? My /var/log/lightdm/x-0-greeter.log contains lines like the following: ** (at-spi2-registryd:1381): WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files ** (at-spi2-registryd:1381): WARNING **: Unable to register client with session manager WARNING: Failed to open sessions directory: Error opening directory '/usr/share/lightdm/sessions': No such file or directory ** Message: PID 1534 (we are 1534) sent signal 15, shutting down... ** (gnome-settings-daemon:1401): WARNING **: Name taken or bus went away - shutting down Searching for these errors results in a variety of bugs filed over the years. Maybe a clean install will fix this.

• Ubuntu One pretends to sychronize files, but it doesn't

  - by Tom Brito

  I have my Ubuntu One account configured in both Ubuntu 11.10 and iOS (ipod-touch). The photos from the iOS were successfully uploaded, but in Ubuntu One, although it shows the "syncing" and "synchronized" marks over the icons, the files are not showing in the website (one.ubuntu.com). In short: My files are not showing in the Ubuntu One website, although the icons have the "uploaded" mark. Any idea what can be wrong here? obs1: Also, not sure if it's related, the icon-marks will show only when I open the Ubuntu One Control Panel. It shows the message "file was uploaded", but there's nothing online. obs2: The folder I'm trying to synchronize is 30mb size. And my connection is 8mbps.

• How to edit files in a terminal with vim?

  - by andrew.46

  It is not always possible to edit and create files in a terminal and I would like to get the answers to the basics of manipulating files in a terminal using vim under Ubuntu Linux. Specific questions I have are: How can I open text files for editing? How can I save the file? How can I save the file with a different name? How can I leave the file without saving the changes? What settings are best in my configuration file and where is this file? How do I set the colors for vim? How do I show line numbers in vim and can this be toggled? A lot of questions here but I believe these questions and their answers should cover basic vim usage...

• Gnome Shell opens as classic

  - by Joe Horgan

  I'm running 12.04 on a Gateway LT4004u netbook, and I installed Gnome3 using the apt-get commands in the terminal. When I rebooted and ran "Gnome Shell" it opened up classic mode. I thought that my cursor might have slipped the first time, but on multiple retries logging in under gnome shell would open the gnome classic desktop. I even uninstalled Gnome Shell and reinstalled it with software center, but I still have the same problem. I was wondering if this might be an issue with my graphics card? Any help would be much appreciated, thanks! -Joe

  Make sure to register here for this upcoming live webcast, with great speakers, and a live Q&A chat session.It is scheduled for Thursday, December 13th, 2012, at 10am Pacific Time. There are no doubts about the strength, and depth, of Oracle's offerings for highly available database environments. But depending on the nature of your data center environments, your different uses cases and workloads, your service level agreements and expectations, there might still be some open questions about what the best solutions and architectures are to assure high availability and/or affordable, efficient disaster recovery. Therefore, this webcast will answer questions such as: How does Oracle GoldenGate fit into Oracle's Maximum Availability Architecture ? When to use Oracle Active Data Guard ? When Oracle GoldenGate ? When both ? When Oracle GoldenGate is a definite requirement for Database High Availability ? Overall, what are new high availability features in Oracle GoldenGate 11g Release 2 ?

Here is my alsabase.conf http://paste.ubuntu.com/1073135/ also a snapshot of alsamixer Any assistance would be greatly appreciated. Thank You and let me know if any more information is required.

• Which CMS can I use for my project?

  - by Nicolás A.

  I have to build a new website for my client.. and he needs this stuff: A user generated content website.. where users can upload their own videos.. (i will use a video hosting platform with api like fliqz.com) I must manage a big user system.. where users can create their own "sub-users"... the site must manage paid subscriptions and payments through paypal.. and other payment gateways... So the question is.. i have to use a pre-built CMS and extend it.. or just a good framework? I've been thinking about joomla, drupal and expressionengine... It's not neccesary to use a open source cms... I've looking at drupal.. but is not as easy to understand and extend... Can anyone help me to make a good decision?

• How to render Minecraft on the GPU?

  - by l0b0

  Hardware: Intel i7 AMD Radeon HD 6970 SSD with plenty of space 6 GB RAM Software OpenJDK 6, 7, and Oracle Java 7 (reproducible with all three) AMD Catalyst 12.8 and open source driver (reproducible with both) Ubuntu 12.04 x86_64 and older Minecraft 1.3.2 vanilla and older On this setup I am getting rubbish frame rates after a short while of playing, dropping from about 45-55 to 15 in a couple of minutes. CPU use is 40-45 even when rendering the opening screen at 1920x1280, and gameRenderer is using about 90% CPU when playing. Rather than trying to eke out a few more FPS out of an obviously broken rendering pipeline, I really hope to find a solution to make the GPU render Minecraft.

  When I had been using Windows 8 my touchpad had multiple gestures: 2 fingers direction top-bottom = vertical revers scrolling(if I scrolled top than page have scrolled bottom); 2 finger direction left-right = horizontal revers scrolling zoom in and zoom out like smartphones with 2 fingers 2 finger rotation = rotate image in image viewer (+ 90 deg or -90 deg) place a finger in the left edge and drag it to right = change windows application, in Ubuntu I want to change the active program to left like Ctrl+Shift+Tab place a finger in the right edge and drag it to left = open right menu and select the option moving finger on direction top-bottom, in Ubuntu I want to change the active program to right like Alt+Tab I succeed enable 2 finger vertical scrolling of System Setings, but I want that it do not work in revers sense. Do it exist a method to enable the rest of gestures and revers the vertical scrolling? edit: It's a Synaptics touchpad.
