• 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)

• 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

• 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.

• 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?

• "Wireless disabled by hardware switch" after suspend and other hardware buttons ineffective - how can I solve this?

  - by fahadayaz

  I have recently purchased a Novatech nFinity N1410 laptop and am having problems with the wireless, which sudo lshw -C network tells me is Centrino Wireless-N 2230 and using the iwlwifi driver. The problem is that after the device has been suspended, I am not able to get the wireless working again without a restart. The network indicator states that the wireless disabled by hardware switch. Though Fn+F2 is meant to be the wireless switch, xev tells me that the system doesn't see it as anything at all when I press this hardware combination. Also, though the brightness up/down buttons work fine, the volume up/down buttons do not work either. What can I do to fix this? I am running Ubuntu 12.10 with all available updates installed.

• 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?

• 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 ?

• 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.

• Remove encryption from USB flash drive

  - by Timic

  It all started when I was attempting to format my PNY USB drive because it was full of junk. When it asked me what type of file system, I selected FAT but there was a checkbox below that said "Encrypt" and I accidently checked it and continue. I had no choice but to come up with a passphrase for it, and so I did, thinking I was able to remove that encryption. But after that at Disk Utility I thought I would find a "Remove Encryption" button or something like that but I didn't. I tried formatting it to remove the encryption but it gives me an error: Error Formatting, The device is busy" Detail>>> One or more block devices are holding /dev/sdb/. I am stuck, what should I do?

• 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!

• 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.

• 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?

• 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.

• 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.

• 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 ?

• 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.

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?

• 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)

• 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.

• Banshee won't sync OGG format to my iphone

  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.
