• Radeon HD 6290 terrible performance on a certified laptop

  - by dac

  I bought Asus K53U laptop, which is Ubuntu certified with pre-installed 11.10. The graphic card is Radeon HD 6290 but 720p playback is terrible. Even page scrolling in Firefox is very laggy. Proprietary drivers are installed by default. How is this possible, why is the laptop Ubuntu certified if the performance is poor? Any solution to this? I just did apt-get autoremove, and after that, this message came out in terminal: Error inserting vesafb (/lib/modules/3.0.0-15-generic/kernel/drivers/video/vesafb.ko): No such device Could that be the problem?

• Distribution upgrade made Ubuntu unusable

  - by Lassi

  I installed today a distribution update from 11.10 to 12.04. This however basically ruined the whole OS. After update I lost all the window borders, icons and even access to the internet. I'm also unable to use the default window manager and I had to use the old gnome. The computer is Acer Aspire 5738G laptop, Intel Pentium T4500, Ati Mobility Radeon HD 560v, 4Gb DDR 3. I am using the open source drivers, not proprietary. Does anyone have any idea what could've happened, and how could I fix this. Help is highly appreciated

• As a Junior Software Engineer should I say that something has been done wrong if I feel so?

  - by Why123

  I recently joined a company and it is my first job. When reading the code base, I felt that the code was not well written. It seemed to me that the code had most of the problems mentioned here and also seemed to have an Anemic Domain Model. There are no unit tests and they don't employ any code quality checking tools like findbugs or pmd. The problem I have is that the code is very difficult to understand. Maybe my conclusions are wrong because I am not that experienced. I need advice on whether to communicate the above facts to a superior or not. If I am to communicate, to whom(Tech Lead, Architect, Product Manager) and how? And if I do communicate will they take it badly since I'm a Junior and has no experience?

• How To Use USB Drives With the Nexus 7 and Other Android Devices

  - by Chris Hoffman

  The Nexus 7 may not have a lot of storage space – especially the original 8 GB model – but you can connect a USB drive to it if you want to watch videos or access other files. Unfortunately, Android doesn’t automatically mount USB drives by default. You’ll need to root your device to enable support for USB drives.

• If an app runs well on iPhone 3GS with iOS 5.1, how to know that it runs well on iOS 4.3? [closed]

  - by ????

  I bought an iPhone 3GS just to test backward compatibility of apps that I developed, but it arrived preinstalled with iOS 5.1. So even if an app runs well on iPhone 3GS and iOS 5.1 with its hardware limitation, how can we tell that it runs well even on iPhone 3GS with iOS 4.3? Will it actually be better to install iOS 4.3 on the phone so that we know even the older iOS can support it, so the newer iOS will work well supposedly? Or is there a need to buy yet another iPhone 3GS and install 4.3 on one and 5.1 on the other? (my assumption is that if we set the app's build target iOS to 4.3, the iPhone 3G won't be able to install it, because iPhone 3G only runs iOS up to 4.2. So the target device is 3GS but not earlier. But it will exclude iPod Touch 2nd Generation as well because they also can only support iOS up to 4.2 only)

• Upgrading 8.10 server to LTS

  - by user3215

  I'm in a plan to upgrade ubuntu 8.10 vbox vm servers to LTS(obviously 10.04) as 8.10 has no support. As far as I know I'll be executing the following to upgrade: apt-get install update-manager-core do-release-upgrade anybody could tell me how could I upgrade a ubuntu server from alternate iso image(Is the alternate iso image used for desktop editons the same used for servers?)? I heard it's possible to upgrade an LTS directly to another LTS and how could I do this after upgrading 8.10 to 9.04 then directly to 10.04 skipping 9.10? 8.10 servers are hosting many services/applications/databases like apache2, tomcat6, ldap, mysql, cvs... and I'm not sure that all of them work as ever after the upgrade. If there is any precautions that I've to following before upgrading, please anyone let me know(ofcourse backup and I'm not going to take backup as I will be trying this on a copy of vdi/vmdk vms) Thanks!

• Error while trying to dual boot Ubuntu alongside Windows 8

  - by Brian

  I recently purchased a new Toshiba Ultrabook that comes pre-installed with Windows 8. I'm trying to dual boot 12.10 with it and I have run into a problem with the installer. When I get to the page to pick the partitions I get this: No drives are listed and the only thing in that device drop down is /dev/sda. If I click Install Now or +/-/change I get an "Ubuntu has stopped working" error message. I'm trying to install off a 12.10 64-bit USB drive in UEFI mode, and I have tried it with secure boot both enabled and disabled with the same results. The hard drive set up is as follows: 500 GB main drive windows recovery (primary) EFI boot section (primary) Windows' partion (280 GB I believe) (primary) unallocated space I created for Ubuntu partition (200ish GB) another Windows recovery partition (primary) 12 GB solid state drive all unallocated space Could it be a problem with the number of primary partitions? I think I read somewhere about a max of 4.

• Kubuntu 12.04 Won't let me search for wireless network

  - by Bora George

  Hello I'm running a brand new Kubuntu 12.04 single boot on my laptop, this is the first time I tried connecting to a wireless network. I tried using the network manager app allready on the task bar, but it doesn't let me tick the column to search for wireless networks, i.e. it will untick it automaticaly, it's dissabled by the software or the hardware, but I doubt it. I've tried searching the other questions on this site, and I can't see anything which helps with my problem. I know my wireless card is a Atheros AR9285, I don't think I installed any firmware for it, I'm sorry I can't offer more info but I'm completely new to networking and all that I have for the network to connect to are it's name and password of course.

• Conscience and unconscience from an AI/Robotics POV

  - by Tim Huffam

  Just pondering the workings of the human mind - from an AI/robotics point of view (either of which I know little about)..   If conscience is when you're thinking about it (processing it in realtime)... and unconscience is when you're not thinking about it (eg it's autonomous behaviour)..  would it be fair to say then, that:   - conscience is software   - unconscience is hardware   Considering that human learning is attributed to the number of neural connections made - and repetition is the key - the more the connections, the better one understands the subject - until it becomes a 'known'.   Therefore could this be likened to forming hard connections?  Eg maybe learning would progress from an MCU to FPGA's - therefore offloading realtime process to the hardware (FPGA or some such device)? t

• Open source management game in java

  - by jcw

  I am trying to find an open source sport management game, much like the link below, but am failing to do so. There are two links provided in the below question that are both fine,'except for one minor problem - I only know java! Is there an open source sports manager project? After some googling, I have been unsuccessful in finding a sports management game that is written in java. I am do not particullarly care about the type of sport, becuase I am mostly interested in mechanics. Does anyone know of any such projects or am I out of luck on java?

• Should I limit my type name suffix vocabulary when using OOP?

  - by Den

  My co-workers tend to think that it is better to limit non-domain type suffixes to a small fixed set of OOP-pattern inspired words, e.g.: *Service *Repository *Factory *Manager *Provider I believe there is no reason to not extend that set with more names, e.g. (some "translation" to the previous vocabulary is given in brackets): *Distributor (= *DistributionManager or *SendingService) *Generator *Browser (= *ReadonlyRepositoryService) *Processor *Manipulator (= *StateMachineManager) *Enricher (= *EnrichmentService) (*) denotes some domain word, e.g. "Order", "Student", "Item" etc. The domain is probably not complex enough to use specialized approaches such as DDD which could drive the naming.

• Double-click instead of single-click in Ubuntu 12.04

  - by evfwcqcg

  When I do a single click, my computer (with Ubuntu 12.04) acts like it was double click. I think it happens in ~50% of cases. It happens with all the program I use: browsers, file manager, terminal and so on. I'm not sure when exactly it started, maybe a week ago, and I don't remember if it started to happen after system-update or after the installation of some packages. What I tried: change mouse change mouse settings like Double-Click Timeout None of those helped me. Any ideas? Thanks.

• Do you think code is self documenting?

  - by Desolate Planet

  This is a question that was put to me many years ago as a gradute in a job interview and it's nagged at my brain now and again and I've never really found a good answer that satisfied me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

• Cannot install build essential from the CD?

  - by munir

  After a fresh installation of Ubuntu 10.10 I tried to install build-essential from the Ubuntu installation CD. I put the cd in the cdrom and in the software repositories i checked the box install from cd(Ubuntu 10.10 release Maverick Meerkat). Then I reloaded the software repositories. The synaptic manager then tried to download some repository related files but failed to do so as i didn't have internet connection. Then I open a terminal and wrote sudo apt-get install build-essential. It prompted me if I want to install build essential y/N. I typed y but the terminal showed some errors and was not installed. I also tried to add the CD in the software repositories. I clicked add and it prompted me to insert a CD while the CD was still inside the cdrom. I clicked "ok" then and it showed it could not find any cd. What is wrong?

• How do I get my folders back on my desktop?

  - by Christopher Allen

  Using the 12.04 version. This morning the Update Manager popped up, I clicked it and it said some items will be un-installed and some will be upgraded and new ones will be installed. I did it and restarted. On restart, I entered my password about 5 times and it said it was incorrect. I changed the shell from Gnome to Ubuntu and logged on then changed it back to Gnome and I was able to log on. However, all my folders on the screen are gone but they appear under Desktop in the Home folder. How do I get then back on the screen?

• How do I toggle sound with amixer?

  - by joschi

  Including Natty I was always able to toggle (mute/unmute) the 'Master' sound volume with the amixer sset Master toggle command that I linked to an edge binding in CompizConfig-Manager. Now after installing Oneiric the command only mutes the sound but doesn't unmute it. I even tried it in the Terminal but it also doesn't work. It changes 'Mono: Playback 68 [78%] [-14.25dB] [off]' to '...[on]' but the sound stays muted so that I have to unmute it via the 'sound-indicator' in the panel. How can I get this working again? What did change since Natty? Does anyone know the command the 'sound-indicator' uses to toggle the sound volume?

• Is acousting fingerprinting too broad for one audio file only?

  - by IBG

  So we were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acousting fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

• How to make in CLI check for updates to be happening every 4 weeks and install them automatically without going to Software sources?

  - by Kangarooo

  I have a set of custom commands I run on my computers after I install them. How do I make Ubuntu check for updates every 4 weeks and install them automatically on check? I would need this done via command line so I can set it up for usual users when I set up their computers. The first command will make the update manager check for updates every 2 weeks because they not always come so much and to save the bandwidth of the Ubuntu servers. I also need to set it so that users don't need to click to install updates since it's tiring every time I help a friend set up a computer.

• Windows Error After Wubi Install

  - by user106563

  The initial install on my laptop was Windows 7. I installed Wubi on Sunday - the install seemed fine. I was able to log in and use both Ubuntu and Windows. On Monday I started receiving the following error in Windows: windows cannot access the specified device path or file This occurs on every link I click on - essentially rendering Windows unusable. I do not experience the same problem when Windows is started up in safe mode. I have tried numerous virus scans (Malware bytes, Avg, AdAware) and have removed various trojans etc. Windows is still unusable. Ubuntu seems fine so far. My question is, can this error be attributed to the Wubi install?
