• Pulseaudio not detecting bluetooth headset automatically

  - by adityap174

  The Pavucontrol on my Xubuntu 13.10 detects my bluetooth headset, but only after I type the command sudo alsa force-reload After a few seconds the headset appears in the configuration tab. I have also tried inserting the line load-module module-switch-on-connect in the /etc/pulse/default.pa but it doesn't help. I have tried purging and autoremoving and reinstalling everything right from alsa to pulseaudio and pulseaudio-module-bluetooth. Nothing works. Is there a workaround to load the headset without using the command force-reload ? To make the pulseaudio daemon recognize the device automatically ?

• 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

• What is the state-of-the-art for using Broadcom Crystal hardware?

  - by echo-flow

  I just bought a Dell Mini 1012, which comes with a Broadcom Crystal media accelerator chip. I'd like to know what is the current state-of-the-art with regard to using this hardware on Ubuntu? What I mean by this is, what is the best way to install drivers to make use of this hardware, and what media players currently support it? I've read that XBMC currently does, but what about gstreamer? Ideally, I'd like to find a solution so that I can accelerate Flash videos using the device. It seems like one strategy may be to download Flash videos to the hard drive and play them with an external, Crystal-enabled media player, and so that seems like one option, but I'm wondering if any of the free flash alternatives (Gnash and Lightspark) support hardware acceleration of flash video using the Crystal API? It seems like there is a lot of information about all of this on the web, but it's not consolidated, and seems like a rapidly moving target, so any insight anyone may have into this would be appreciated.

• Wireless xbox360 pad connected with xboxdrv doesn't show in jstest

  - by Kyle Letham

  So Lubuntu 13.04, 3.4.0. I'm trying to use my wireless xbox controller. I've installed xboxdrv. I have to run it with sudo, or I get USBController::USBController(): libusb_open() failed: LIBUSB_ERROR_ACCESS. If I connect the adapter, run the program, and then press the button on the gamepad to connect it, it never really connects - just flashes like it's searching. If I reboot, leaving the controller searching, and run the command again while it's searching after I boot up, the controller connects (the light becomes solid in one corner). Using pkill xboxdrv and then relaunching it doesn't work. Regardless, no matter what I do, the gamepad never shows up in jstest-gtk. sudo xboxdrv --debug gives me: Controller: Microsoft Xbox 360 Wireless Controller (PC) Vendor/Product: 045e:0719 USB Path: 002:005 Wireless Port: 0 Controller Type: Xbox360 (wireless) [DEBUG] XboxdrvMain::run(): creating UInput [DEBUG] XboxdrvMain::run(): creating ControllerSlotConfig [DEBUG] UInput::create_uinput_device(): create device: 65534 [DEBUG] LinuxUinput::LinuxUinput(): Xbox Gamepad (userspace driver) 0:0 Any ideas?

• Wireless Very slow with 13.10 and BCM4313

  - by RyanCheu

  I have a laptop with the BCM4313, and it was working perfectly in Ubuntu 13.04, but I recently upgraded to 13.10 and now my wireless performance is horrible. Initially it didn't work at all, but I removed the wl driver and use the brcmsmac driver instead. Now when I boot up it works at the start, but gets progressively slower. My Android device is reporting 10Mbps down/20Mbps up, but my laptop only gets 1up/down. Does anyone know a solution? I really need my wireless to work, is my best option to just reinstall on 13.04? Thanks!

• broadcom 43225 wireless on acer laptop is disabled

  - by Robbie

  I have a acer aspire 5820T with a broadcom 43225 wireless card. I previously used ubuntu 10.10 and the wireless worked straight away, but when I updated to 11.04 the wireless stopped working. I have managed to get the wireless hardware to switch on for a couple of seconds before turning off (When you turn the wireless on using the manual switch the wireless light stays on for a couple of seconds and in the drop down connections menu the information under wireless networks changes from 'device not ready' to 'Disconnected' but shows no wireless networks despite there being one). So far I have tried installing an additional driver, and also disabling the additional driver and installing b43-fwcutter and firmware b43 installer. There may have been other things that I've found in searches that i've tried but unfortunately I can't remember them. Any help would be appreciated.

• Oracle BPM and Open Data integration development

  - by drrwebber

  Rapidly developing Oracle BPM application solutions with data source integration previously required significant Java and JDeveloper skills. Now using open source tools for open data development significantly reduces the coding needed.  Key tasks can be performed with visual drag and drop designing combined with menu selections entry and automatic form generation directly from XSD schema definitions. The architecture used is extremely lightweight, portable, open platform and scalable allowing integration with a variety of Oracle and non-Oracle data sources and systems. Two videos available on YouTube walk through the process at both an introductory conceptual level and then a deep dive into the programming needed using JDeveloper, Oracle BPM composer and Oracle WLS (WebLogic Server) along with the CAM editor and Open-XDX open source tools. Also available are coding samples and resources from the GitHub project page, along with working online demonstration resources on the VerifyXML site. Combining Oracle BPM with these open source tools provides a comprehensive simple and elegant solution set. Development times are slashed and rapid prototyping is enabled. Also existing data sources can be integrated using open data formats with either XML or JSON along with CRUD accessing via the Open-XDX Java component. The Open-XDX tool is a code-free approach where data mapping is configured as templates using visual drag and drop in the CAM Editor open source tool.  XML or JSON is then automatically generated or processed (output or input) and appropriate SQL statements created to support the data accessing.   Also included is the ability to integrate with fillable PDF forms via the XML templates and the Java PDF form filling library.  Again minimal Java coding is needed to associate the XML source content with the PDF named fields.  The Oracle BPM forms can be automatically generated from XSD schema definitions that are built from the data mapping templates.  This dramatically simplifies development work as all the integration artifacts needed are created by the open source editor toolset. The developer level video is designed as a tutorial with segments, hands-on demonstrations and reviews.  This allows developers to learn the techniques and approaches used in incremental steps. The intended audience ranges from data analysts to developers and assumes only entry level Java skills and knowledge.  Most actions are menu driven while Java coding is limited to simply configuring values and parameters along with performing builds and deployments from JDeveloper and Oracle WLS.   Additional existing Oracle online training resources can be referenced on Oracle BPM and WLS that cover other normal delivery aspects such as user management and application deployment.

• Banshee won't sync OGG format to my iphone

  - by Daze

  I have a jailbroken iphone 3g with 16 gigs of memory and I've been putting my music on it from banshee lately and have been having almost no issue. Unfortunately, I just added a few albums to my Banshee library and tried to sync them to my iphone, but every time I try, i see a hundred or so errors saying that the device doesn't support the ogg format and there was no converter found. I'm still pretty much a newb at this stuff, so please help me and dumb down your answer. I'm running 12.04 and again, using an iphone 3g with no sim card, but it's been jailbroken and is used primarily for it's music function.

• Laptop not syncing with Ubuntu One

  - by Lolwhites

  I have a desktop running Maverick, and a laptop running Lucid. Both are supposed to be linked to my Ubuntu One account. The desktop syncs fine, but when I started the laptop for the first time in a couple of months, it wouldn't sync any more. The Ubuntu One Preferences window either reports "Synchronisation complete" even though no recent files have been downloaded nor have any test files created in the relevant synced folder been uploaded, or it says "Synchronisation in progress", which does not appear to be happening as it stays like this for ages and the lights on my router suggest no traffic is going through. Have repeatedly tried disconnecting and reconnecting, and removing the device from the account then reattaching it, all to no avail.

• How to set up offline manifest for a web app to run in Safari in iOS?

  - by ahmd1

  I'm currently trying to set up an offline.manifest file for my web app to be used offline on an iOS device. For testing purposes I have a very simple HTML page that I'm trying to add to a home screen. I'm testing it on a live iPhone 4, but after the page is added to the home screen and I put the iPhone in the airplane mode and try to start my web app I get this error: "Turn Off Airplane Mode or Use Wi-Fi to Access Data" and then if I click OK I get: "Cannot Open Web App Name" "Web App Name could not be opened because it is not connected to the Internet" The following is added to the HTML file: <!DOCTYPE html> <html lang="en" manifest="scrts/offline.manifest"> and the offline.manifest is composed as such: CACHE MANIFEST ../pics/bkgnd_iphn_settings.png ../pics/mbl_btn_fb.png ../pics/mbl_btn_twt.png ../pics/icon_57_57_bg.png ../pics/icon_72_72_bg.png ../pics/icon_114_114_bg.png ../pics/icon_144_144_bg.png ../pics/splash_320_460_bg.png ../pics/splash_768_1004_bg.png ../pics/splash_1004_768_bg.png I got all instructions on composing it from here I also adjusted the .htaccess file to add this line: AddType text/cache-manifest .manifest Any idea what am I not doing right?

• Ubuntu 14.04 doesn't detect my discrete GPU

  - by user258887

  I recently purchased a laptop with an Nvidia GeForce 860m, and have installed Ubuntu 14.04. On my old laptop I had 12.04, which automatically filled Additional Drivers with Nvidia drivers. But on this computer, the only thing in Additional Drivers is Qualcomm. So I manually installed Nvidia, but X Server Settings doesn't seem to detect any GPU... lspci | grep VGA reports only my integrated Intel GPU, but lspci -v reports many things, including the Nvidia GPU: 01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 860M] (rev a2) Subsystem: ASUSTeK Computer Inc. Device 157d Flags: fast devsel, IRQ 16 Memory at ec000000 (32-bit, non-prefetchable) [size=16M] Memory at c0000000 (64-bit, prefetchable) [size=256M] Memory at d0000000 (64-bit, prefetchable) [size=32M] I/O ports at e000 [size=128] Expansion ROM at ed000000 [disabled] [size=512K] Capabilities: access denied Don't know what any of that means. Not sure if it's supposed to say 'access denied'... I need my GPU to do CUDA and OpenGL programming. What else can I do to figure out why this isn't working?

• Is there a way to emulate pinch-zoom?

  - by aking1012

  I'm looking for a way to emulate pinch zoom in either an android emulator(android SDK-less desirable) or a (preferred) native Ubuntu web browser that I can resize to a specified size for initial testing of HTML5 applications. This is would be useful for first round testing during cross-platform application development. Note: I'm trying to do this with no real touch-device only a mouse. So the best answer would be something like "Install this chromium plug-in and use this hotkey to set pinch points" or something similar. We already have this for getting dual mouse working(thanks AmithKK). The browser that supports multi-touch is the hard part. Something to note is that I start getting screen artifacts using multiple mice via that guide. They're mild and tolerable, but they are there.

• How to control fan speed and temperatures on Asus A8Js laptop?

  - by Azeworai

  I have tried installing asusfan and lm-sensors but I'm unable to control my fans to cool my laptop down sufficiently. Currently it overheats at about 100 degrees celsius and my sensors output somehow does not have any fan information on it: jackson@OLYMPIA:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +69.0°C (crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +66.0°C (high = +100.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +66.0°C (high = +100.0°C, crit = +100.0°C) I have checked my bios and there isn't any fan settings there. I can consistently overheat just by converting a video via Handbrake. I have ubuntu-desktop installed for a GUI. Is there a way for me to control my fans to start spinning before it reaches a critical temperature and kills itself?

• Lenovo e530 no wireless Ubuntu 13.04

  - by Sam

  For some reason my wireless will not work on my Lenovo e530. I am dual booting ubuntu and windows 8 and my wireless works in windows. I saw online that I should run rfkill. I did that but only bluetooth shows up. There is no difference when I press the wireless fn key either, but it does block bluetooth (as it should). I'm really wanting to get into Ubuntu but this is holding me back. To clarify the wireless device does not show at all after running rfkill.

• Broadcom 4365 wireless driver on 12.04 with 3.4 / 3.5 kernel

  - by zaid

  I used this package to install the driver on 3.2 Kernel and it was working perfectly. Unfortunately the system used to freeze randomly with 3.2 kernel so I installed 3.4 kernel, now there is no freezing, the only problem is that my wifi card is not working, I tried to re-install the package, but didn't work. I can see the driver in the "additional drivers" and it say that it is active, but when I execute iwconfig it doesn't show up. I've even tried ndiswraper and that didn't work either. my lspci: 01:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01)

• Ubuntu doesn't find hdds with higher clock rates

  - by user136243

  I dual boot windows 7 64-bit and ubuntu 13.10 64-bit on separate disks, and utilize some overclocking from the BIOS. Windows works fine, however ubuntu can't seem to find any hard drives, except for at stock cpu speeds. While attempting to boot it says Gave up waiting for root device... and ALERT! /dev/sdb7 does not exist. Dropping to shell! A bootable usb stick still works, but gparted doesn't detect any other drives. Have tried: Boot-repair Changing SATA mode in BIOS Newer kernels Older ubuntu versions Not sure it's relevant, but the motherboard is a Gigabyte GA-A75M-UD2H with the newest BIOS version, the CPU an AMD Llano. This is hardly a fatal error, but it's inconvenient to change BIOS settings whenever I want to switch OS, and furthermore I'm quite curious about why it won't work. I'd appreciate any insight into what the actual problem is. So how can I resolve this issue ?

• Is there an open source alternative to "Adobe Digital Editions"?

  - by soulsource

  For the moment I run Adobe Digital Editions under Wine to download ebooks burdened with ditigal restriction management. I only use it to open .acsm files supplied by ebook-shops, which contain authentication information required to download the actual DRM'ed ebook files, which I then transfer to my reader-device with calibre. My question is, if there exist open source alternatives to Adobe Digital Editions. They don't need much functionality. I just want to put the .acsm-file in and get the .epub out (no, I don't want to remove the drm, that'd be illegal afaik).

• Can not install Ubuntu 12.04 or 12.10 on Toshiba qosmio x870. Please help!

  - by Mighty

  I have a new Toshiba qosmio x870 and for the past one week I have been trying to install Ubuntu 12.04 from a USB and Live CD without success. I keep on getting this error: Boot failure: a proper digital signature was not found. One or more files on the selected boot device was rejected by the Secure Boot feature. I even tried installing Ubuntu with the Windows installer. After installation and I reboot the PC, first I see the error that points to: \ubuntu\winboot\wubildr.mbr Status: 0xc000007b Info: The OS couldn't be loaded because a required file is missing or contains errors. When I restart, that the previous error doesn't show up and I see both Windows 8 and Ubuntu (happy that I was successful) but when I click on Ubuntu, it flags an error. This is the first time I'm having a Secure Boot-capable PC. What will be the danger in disabling the secure boot? I'll be happy if I can get assistance from anyone.

• Energy saving with two batteries (Gigabyte S1080 and similar)

  - by user37155

  my today question is: how do I manage a tablet (Gigabyte 1080) with an additional battery in Ubuntu ? The control bar shows two separate batteries but starts to suck all the energy from the secundary battery, not leaving any power in it and ruining it (if I don't remove it earlier), and then starts with the primary battery. Here you find a description of the secundary battery: http://www.gigabyte.com/products/product-page.aspx?pid=3837#kf Do you have some solutions for a more confortable use of te device, with windows-like drivers maybe ? Is there a graphical tool to manage two batteries in Linux, in order not to ruin them, and possibly to save energy with them ? Many thanks and greetings, Francesco

• How do I plot individual pixels using the XNA APIs?

  - by izb

  If I wanted to fill my game screen with individually coloured pixels, how would I do this? For example, if I wanted to write a 'game of life'-type game where each pixel was a cell, how would I achieve this using XNA? I've tried just calling SetData() on a Texture2D object using a screen-sized array of Color values, but it complains with: You may not call SetData on a resource while it is actively set on the GraphicsDevice. Unset it from the device before calling SetData. How do I do as it asks? Or better still... is there an alternative, better, efficient way to fill a screen with arbitrary pixels?
