• Problem installing from Ubuntu 12.04.1 LTS 32bit cd

  - by John Smith

  Older laptop currently running xp, only 128mb ram too. Is 128 just too small? But, 20+ gigs free hard drive and it's been defragmented. When I try to install Ubuntu from a CD I get the screen that says ubuntu and has the four red dots and then eventually goes blank and I just hear hard drive noises. Stays this way indefinitely (shut it off after half a day). Burned another cd, at slow writing speed too, and dl is from Ubuntu and get same result. Any help much appreciated!

• OBI already has a caching mechanism in presentation layer and BI server layer. How is the new in-memory caching better for performance?

  - by Varun

  Question: OBI already has a caching mechanism in presentation layer and BI server layer. How is the new in-memory caching better for performance? Answer: OBI Caching only speeds up what has been seen before. An In-memory data structure generated by the summary advisor is optimized to provide maximum value by accounting for the expected broad usage and drilldowns. It is possible to adapt the in-memory data to seasonality by running the summary advisor on specific workloads. Moreover, the in-memory data is created in an analytic database providing maximum performance for the large amount of memory available.

• Unity poor performance after upgrading to 13.10

  - by Juzer Ali

  I upgraded recently from 13.04 to 13.10. I have Dell Inspiron 4GB RAM, Intel Core i3. Login takes a lot of time and all the graphics are very slow. Alt + Tab takes a lot of time (seconds). After reading some threads, I also removed Cinnamon desktop, but it didn't change anything. I had to ultimately fall back to Gnome Flashback (no effects). Gnome flashback works fine without any issues. Can anyone please help me get back to Unity, else I will have a very hard time running using Gnome.

• Ubuntu slow on HP 2000 notebook with Apu e1-1200

  - by user169861

  I am using HP 2000 notebook which initially came with Windows 7 64bit. It has 4gb ram, AMD APU E1-1200 (1.4ghz) with Radeon 7310. With Windows it worked ok, so I decided to switch to Ubuntu. I installed 13.04 64bit at first, but responsiveness wasn't that good (opening windows, menus, Firefox, dash search) even if it was way better during the testing from live USB. I tried different kind of drivers for graphic card, 13.6beta, 13.4, fgrlx proprietary, upgraded kernel but the situation was the same. Then I tried installing 32bit version but the results were identical. After that I tried LTS version 12.04 and Xubuntu 13.04.. Responsiveness wasn't that different at all. Not sure what to do, and I wouldn't want to go back to Windows. This machine is not a beast, but it should be enough to deal with Unity or Xfce without troubles. Oh yes, I have insydeH20 BIOS with not so many options at my disposal. Thanks and best regards,

• Mock Objects for Testing - Test Automation Engineer Perspective

  - by user9009

  Hello How often QA engineers are responsible for developing Mock Objects for Unit Testing. So dealing with Mock Objects is just developer job ?. The reason i ask is i'm interested in QA as my career and am learning tools like JUnit , TestNG and couple of frameworks. I just want to know until what level of unit testing is done by developer and from what point QA engineer takes over testing for better test coverage ? Thanks Edit : Based on the answers below am providing more details about what QA i was referring to . I'm interested in more of Test Automation rather than simple QA involved in record and play of script. So Test Automation engineers are responsible for developing frameworks ? or do they have a team of developers dedicated in Framework development ? Yes i was asking about usage of Mock Objects for testing from Test Automation engineer perspective.

• How to adjust TouchPad edge scroll area in Ubuntu?

  - by MikeVB

  I have an Acer Aspire that I have dual booting XP and Ubuntu. On the Windows side, the driver allows you to set how close your finger has to be to the edge of the TouchPad before it goes into scroll mode. In Ubuntu I don't have the option (at least in the GUI) to change the scroll area on the pad. Is there a conf file or other way to change this? I'm constantly getting into the scroll area during normal usage. I would like to leave it on without losing so much pad area to the scroll feature.

• If Ubuntu freezes when running off a USB drive, will it freeze after full installation?

  - by fearoffours

  I'm planning to install Ubuntu on an aging Compaq Presario V5000. I've established that the Unity desktop is not suited to this laptop, and am now using the standard (Gnome?) desktop. I'm grappling with ndiswrapper and my wireless chipset. But I'm still running it off a USB drive before I take the plunge and install properly to my internal HD. Part of my reticence in completing the installation is I'm experience freezes after about 10-20 minutes usage. Is this likely to be in any way related to running it off the USB drive?

• eDelivery (Delivery Cloud) Housekeeping - removal of obsolete EPM products

  - by THE

  You may have noticed that Weblogic Server (WLS) 9.2.X and WLS 10.0.X releases have been removed from the Oracle Software Delivery Cloud. The Delivery Team has been asked to remove or update any product pack or product that embeds WLS 10.3.2 or earlier versions. This is consistent with general Oracle practice of removing old product versions from public distribution systems, and encourages customer usage and adoption of newer product releases such as WLS 10.3.3 or newer.  For the convenience of existing supported customers, a media request SR on My Oracle Support can be entered to obtain any removed media.  Information on how to open such an SR can be found on  MOS Doc ID 1071023.1 . OTN will also be reviewed and similar modifications may potentially be done.  The following media packs will be removed from E-Delivery this week, as of the above reason. Hyperion 9.3.1 Hyperion 9.2.1 Hyperion Pre-system 9 EPM 11.1.1.3 EPM 11.1.1.4

• Instruct Ubuntu to boot TORAM from flash drive using unetbootin

  - by Goyuix

  I have used UNetbootin to create an installable / live bootable flash drive from Ubuntu 12.04. However that didn't preserve the normal Ubuntu boot menu which allows to me to enter advanced options. It has a custom menu that I can pick from predefined choices like "Install Ubuntu" and "Try Ubuntu without installing". What I would like is to be able to boot from the USB flash drive, but then be able to remove it from the computer once the desktop has loaded. The laptop I would like to use this on does not have a CD/DVD drive. What do I need to modify on the flash drive to add an option to "Try Ubuntu (RAM)" that passes the TORAM=yes parameter to the initrd options? Are their other things I need to touch/change as well? Bonus: I would guess the answer would also allow for other options like acpi=off as well, but if it is different I would appreciate having that answer too.

  - by Paul Sorensen

  The role of Java developer may just be better than ever. An excellent article in Java Magazine discusses the availability of web-based tools that help development teams more effectively manage their projects and modules. If you are a Java developer you should definitely read this article. I especially like the Expert Opinions scattered throughout the article. These highlight real-world usage of the latest and greatest development tools.  As you consider steps to move your career forward, consider Java certification. Oracle has over 15 unique Java certification credentials available. The process of becoming certified in Java and preparing for your exams will require you to study, learn and practice (code). All of this activity will help you sharpen your skills and increase your working knowledge of Java - making you a better developer and more valuable member of your team. You can use the Certification Finder on the Oracle certification homepage to find a Java certification that is right for you. Thanks!

• Override Built-In Maverick Keyboard Shortcuts

  - by jrc03c

  Having used the Command+M keyboard shortcut to minimize windows in OS X, I'd like to use the same functionality in Ubuntu 10.10. When I try, though, it only brings up the "communications" section of the indicator applet; like so: In the Keyboard Shortcuts preferences, I have set as the minimize shortcut Mod4+M, which I got by capturing the Apple Command key and the M key. I find no other shortcut using this key combination in Keyboard Shortcuts, and yet I cannot get the window to minimize when using it. Does anyone know how to override Ubuntu's default usage of this key combination? Thanks!

• How much server bandwidth does an average RTS game require per month?

  - by Nat Weiss

  My friend and I are going to write a multiplayer, multiplatform RTS game and are currently analyzing the costs of going with a client-server architecture. The game will have a small map with mostly characters, not buildings (think of DotA or League of Legends). The authoritative game logic will run on the server and message packet sizes will be highly optimized. We'd like to know approximately how much server bandwidth our proposed RTS game would use on a monthly basis, considering these theoretical constants: 100 concurrent users maximum 8 players maximum per game 10 ticks per second Bonus: If you can tell us approximately how much server RAM this kind of game would use that would also help a great deal. Thanks in advance.

• update-apt-xapian-index uses 100% CPU, even when Update Manager is set to not check for updates

  - by Dave M G

  I have a slightly older laptop running Ubuntu 11.10. It runs fine, but frequently, when I start it up, the CPU monitor in my Gnome Panel shows 100% usage for for what can be up to five minutes or so. It seems that the offending process is update-apt-xapian-index, which, if I understand correctly, is the update manager checking for updates. I have gone into the update manager settings, and selected to never check for updates. I'll do that manually when I feel like I have the time to leave the laptop running for that. However, despite my selection, this still happens. Roughly 50% of the time or more, when I start my laptop, it runs update-apt-xapian-index. How can I get the update manager to respect my settings, or at least to get this process to stop eating my CPU cycles?

• No graphics after installing AMD Catalyst 12.4 and installing the recommended updates afterwards

  - by Innonic

  Some days ago, I installed Ubuntu 12.04. Since I wanted to use dualview using an external display I installed the propriatary AMD Catalyst 12.4. The graphics are fine, but if I run the updates found by the updates manager, Ubuntu won't be able to start with graphics after reboot. I installed Ubuntu 3 times until I realized what the problem was. So now I got the basic installation with Catalyst running but I can't update the system. Is there any solution to this? Or can I somehow identify which update causes this? My System is a Lenovo y560 Ideapad (Intel Core i7, 8GB RAM, with AMD Radeon HD 6570M/5700 Series. Thank you in advance

• How to Name Groups of Apps on the Windows 8 Metro Start Screen

  - by Taylor Gibb

  The Windows 8 Start Screen certainly takes some getting use to, however, one of the things that I really miss about the Start Menu was how i was able to categorize my installed applications. While you cant create folders on the Start Screen, you can group your applications. To get started head over to the Metro Start Screen and move your mouse to the bottom right-hand corner, clicking on the small icon. Now right click on the group of apps that you want to name.

• The Ubuntu Advantage Service right for my non-profit?

  - by Robert

  My small 5 computer office currently runs on Ubuntu. 2 of the desktops run Windows7 in Sun Virtualbox software, and are used for Quickbooks. I am going off to college, and I am looking for a paid tech support solution to replace my IT position. I have an approx $300/mth budget, and I am wiling to discuss higher rates. Everyone in the office is currently comfortable with regular desktop usage, but I am handling all of the software installation and updates. I was hoping to get a total support package for all of their tech related questions, but I cannot find any services which will support linux. Is the Ubuntu Advantage Service something which can take my place? They would mostly need network help, printer help, and an occasional software compatibly troubleshooting session. If this is not a solution, does anyone know of a tech support forum/hotline which would cover all of this? Thank you for reading.

• Dimming the backlight is irreversible on a Samsung Q210 notebook, what do I do?

  - by user27304

  I'm new to the community, although I have been using Ubuntu since 2010. I have a Samsung Q210 notebook; Specs: Intel® Core™2 Duo CPU P8400 @ 2.26GHz × 2 4 Gigs RAM Nvidia 9200m GS (although system information in Ubuntu doesn't know) 194 GB HD OS: Ubuntu 11.10 Kernel is 3.0.0-12-generic-pae Although Samsung seems to be infamous for problems with Ubuntu, after upgrading to Oneiric, finally the FN Brightness Buttons are recognized. The only problem is, after dimming the backlight for a fixed amount of steps (3 or 4, I dare not count now because that would mean rebooting because I can't see anything), the display goes completely dark and using the FN buttons to brighten the backlight does not work anymore (before reaching that threshold, going brighter after dimming works). Now what do I do? File a bug report? If not, what then? If yes, how? Not sure... guess I should ask here first.. thanks for answering in advance.
