• Music Manager that can properly see ID3 ratings tags and synchronize with Android

  - by Sebastian

  I'm moving from Windows 7 to Ubuntu, and so far the experience has been a really good one :) However, there is something that I've used to do with Windows 7 that I can't find how to do in Ubuntu: From my Windows music manager programs (either MediaMonkey or Windows Media Player) I could set song ratings in a way that the ratings set from either program could be also read from the other one. Additionally, song ratings were visible and updated in my iPod Touch when I synch'ed my music (either manually or using iTunes). To sum up, it seems that MediaMonkey, WMP, and the iPod device use standard mp3 metadata tag for ratings. Now, using Ubuntu 12.04, and now with an Android device: Rhythmbox can't see the song rates, despite those ratings can be seen by MediaMonkey and MS Music Player when I boot with Win7. Is this an issue I can fix with some setting? Is there any program I can use to accomplish this? What do you recommend to sync my music with Android (4.0, Galaxy s2), also keeping the song ratings information updated between Android and my PC? Thanks!!

• 12.10 no audio via hdmi and video speeds up

  - by jackson

  I have a laptop with an ati radeon 4200, on 12.04 everything worked fine, since upgrading to 12.10 I cannot get sound over the hdmi. When I switch to hdmi audio the video speeds up to about 2x. I can use the speakers in my laptop and watch video via hdmi with no problems. Things I have tried: Various tutorials to install the AMD/ATI drivers, all of which resulted in low graphics mode. Checked that everything is properly set in alsamixer, the sound utility and - installed pavucontrol and checked everything in there. Verified the output from cat /proc/asound/cards looks normal When I initially upgraded there was a plethora of problems which I believe were due to the old proprietary driver still being used but not compatible, after a few hours trying to fix that I decided just to back up and do a fresh install which works great except for the above stated problem. Any help would be greatly appreciated!! Finally hopefully this hasn't already been answered, I have tried a few different searches on the boards and haven't come up with anything. $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: ALC269VB Analog [ALC269VB Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 0/1 Subdevice #0: subdevice #0

• My Windows Phone 7 experience: 45 days in

  - by Enrique Lima

  November 13th, 2010 was the day I got my Windows Phone 7.  It was an exciting day, a lot of anxiety too.  Over a phone? Sadly, yes! Being a Zune Pass subscriber, it was something worth looking forward too, being a consultant that relies and works with Microsoft technologies and having the option of OneNote (without converters and such) on my phone was a great thing too. Has that changed over 45 days?  No, not really.  But I find myself at the very same place I was with my iPhone, I don’t really use the music player as I spend enough time in front of a computer where I have Pandora and the Zune Desktop.  Or in a car with Satellite Radio.  As for OneNote, that keeps me hooked and with access to my notes no matter where I take them. The Device: Samsung Focus Likes: OneNote integration, Zune capabilities (just note my comment above), fast and smooth interface, calendar, tiles, the device itself. Dislikes: Heavy glitches in SharePoint interaction. And a very weird one I have experienced is, any pictures I get sent from an iPhone via email will register as an attachment but the pictures are not listed as the attachment once I open the message … weird!!  Then, of course, some apps have not made it to the platform (not sure they ever will … Pandora??!!??  Chase??!!??).  But those apps missing is not the phone, or Microsoft’s fault (IMO).  In summary, I am happy with it, and some of the missing apps have made me shift the way I work with the products or features affected … meaning I rely on my desktop stuff for that.

• Repair ext4 filesystem on USB drive

  - by phineas

  Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB. The hardware looks intact, I hope for the best for repairing the ext4 filesystem. I followed the instructions from HOWTO: Repair a broken Ext4 Superblock in Ubuntu, but I wasn't successful. # fsck.ext4 -v /dev/sdb e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Filesystem blocks are invalid, however when I run the recommended solution to try the alternate superblock, I get the following output: # e2fsck -b 8193 /dev/sdb e2fsck 1.42.5 (29-Jul-2012) e2fsck: Invalid argument while trying to open /dev/sdb plus the same error message as in the last paragraph above. Any ideas how to recover the drive? Thank you very much! Edit: testdisk won't help. I'm still stunned why the tools only discover 17 MB.

• Running Ubuntu Server from a USB key / thumb drive (being mindful of flash's write limitations)

  - by andybjackson

  Having become disillusioned with hacking Buffalo NAS devices, I've decided to roll my own home server. After some research, I have settled on an HP Proliant Microserver with Ubuntu Server and a ZFS RAID-Z array for data. I settled on this configuration after trying and regretfully rejecting FreeNAS because the Logitech Media Server (LMS) software isn't available on the AMD64 flavour of this platform and because I think Debian/Ubuntu server is a better future-proof platform. I considered Open Media Vault, but concluded that it isn't quite yet ready for my purposes. That said, FreeNAS does include the option to run itself off a 2GB+ flash device like USB key or thumb drive. Apparently FreeNAS is mindful of the write limitations of flash devices and so creates virtual disks for running the OS, writing only the required configuration information back to flash. This would give me an extra data drive slot. Q: Can Ubuntu Server be configured sensibly to run off a flash device such as a USB key/thumb drive? If so, how? The write limitations of flash should be accounted for.

• Changing the Default Windows Phone 7 Deployment Target In Visual Studio 2010

  - by mbcrump

  After you download and install the January 2011 Windows Phone update, you will notice one annoying thing. The default deployment target for Windows Phone Projects in Visual Studio changes to Windows Phone 7 Device. Before the update, it defaulted to the Emulator. I found this extremely annoying as I’m more than likely going to test with the emulator before putting it on my actual device. Now to make things fair, Microsoft told you they were going to switch the default and even provided a solution, but you will have to check a tiny paragraph in the release notes. The good news is that its very easy to do: Simply navigate out to : %LocalAppData%\Microsoft\Phone Tools\CoreCon See the folder named, “10.0”? Go ahead and delete it. Now, the folder will be completely empty and if you fire up Visual Studio 2010 you will see we are now defaulting to the Emulator again. In my opinion, this should have been left at Emulator. Now, new WP7 developers will get a build error when they first start a WP7 project and will not know why until they read the error list.  Subscribe to my feed CodeProject

• Issues in pulse audio in Ubuntu 11.10

  - by Kamal

  Good Morning All. I am a new ubuntu user. So please forgive me if this question is too basic. I have installed Ubuntu 11.10 in my machine. I have logged in as USER_A. My external audio device is a Headset and I was able to hear the audio properly. I need to join my Ubuntu machine to a window's domain (my office server). I followed the steps explained in http://www.ghacks.net/2010/04/21/join-a-ubuntu-machine-to-a-windows-domain/ and was successful in joining my ubuntu machine to the windows domain. sudo apt-get install likewise-open5 sudo domainjoin-cli join DOMAIN USER_B Now when I logged in as USER_B, there is no audio for this user in the same machine. I crossed check with my User_A account. There is no issues with the sound for User_A. Only for User_B, there is no audio. When I checked the sound settings of User_B, there is no device listed in Hardware, Input and Output. Whereas for User A, my Headset is listed in Input and Output. Can anyone please help me on this. Why there is no sound for User_B? Thank you.

• Can't connect to Wireless Network - Ubuntu 12.04 LTS & Sabrent A111N USB Dongle

  - by Ohgodwhy

  I've been trying to connect to this network for quite some time. I can't directly connect to the router with a Wire, but can access the Router with other wireless devices without any issues. I had previously tried several other Wifi nic's but none of them would load properly. Today, i went and bought a new (supported) Sabrent A111N USB Dongle, which said explicitly that it works with Linux 2.4 +. I popped the Dongle in, and low-and-behold it immediately said that there were Available Wireless Connections. I selected my connection and tried to connect, but it just loops constantly while saying Wireless Disconnected then attempts to connect again over and over. ifconfig and iwconfig both show my device in a ready and working state. However, iwlist wlan0 scan says that there are no results found. I don't get it... At one point, I could see the CPU in the DHCP client list under the router, but it doesn't fully make the connection (something about a timeout?). Any help would be appreciated.

• Why do I get disk I/O errors booting the 3.2 kernel on a xen vps server?

  - by Doug

  I have a xen vps, which I just upgraded to the new LTS 12 Precise Pangolin.

Anyone? Anyhow, until this is resolve I strongly recommend against upgrading if you're running a xen server.

• Wubi installation broken by update - now unable to mount

  - by Outspaced

  As of today, my wubi installation of Ubuntu won't boot (goes straight to 'minimal bash-like interface) and I am unable to mount it when I boot straight to Ubuntu. If I boot straight into Ubuntu (not using Wubi, not going via Windows), I am able to mount the Windows partition and see the Wubi partition there: sudo mount -t ntfs /dev/sda5 /media/winxp And from there I can see the wubi root disk: /media/winxp/ubuntu/disks/root.disk But if I try to mount this: sudo mount -o loop /media/winxp/ubuntu/disks/root.disk /media/wubi I get an error: /media/winxp/ubuntu/disks/root.disk Input/Output Error If I then try fsck: sudo fsck /media/winxp/ubuntu/disks/root.disk I get this: Input/Output Error while trying to open /media/winxp/ubuntu/disks/root.disk The Superblock could not be read or does not describe a correct etx2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt and you might want to try running e2fsk with an alternate superblock: e2fsck -b 8193 <device ... this gives me the same result. There is data on this partition that I really need to be able to access, so I can't delete and reinstall. Any help much appreciated. Thanks.

• Why is rvalue write in shared memory array serialised?

  - by CJM

  I'm using CUDA 4.0 on a GPU with computing capability 2.1. One of my device functions is the following: device void test(int n, int* itemp) // itemp is shared memory pointer { const int tid = threadIdx.x; const int bdim = blockDim.x; int i, j, k; bool flag = 0; itemp[tid] = 0; for(i=tid; i<n; i+=bdim) { // { code that produces some values of "flag" } } itemp[tid] = flag; } Each thread is checking some conditions and producing a 0/1 flag. Then each thread is writing flag at the tid-th location of a shared int array. The write statement "itemp[tid] = flag;" gets serialized -- though "itemp[tid] = 0;" is not. This is causing huge performance lag which technically should not be there -- I want to avoid it. Please help.

• No sound after upgrading to Ubuntu 11.10 from win7

  - by Tilman

  just as a prefix to my question, i'd like to note that i'm just now entering the world of Linux (unless you count my android, but that's a very different experience...) i have two computers now that run Ubuntu 11.10, the first of which i've had very little problems with, aside from figuring out the basics. the second, from which i'm writing this question, has (up to this point) only had one problem.... no sound. i've read a couple questions similiar and found little help as the component catalog doesn't have my computer listed. (in fact i'm not suprised this is a pos i had my mom grab from her work before they officially closed the doors behind them) had perfect sound before hand, and no sound now. sudo lspci -v brings up 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) Subsystem: Intel Corporation Device d608 Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at ff980000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel any help would be greatly appreciated, me and my gf just wanna watch a damn movie lol

• WIN7 and Ubuntu lost after Installing ubuntu 12.04 and win7 dual system ,I have no OS on my laptop now

  - by abos

  Here is the procedure: In the morning I installed ubuntu using a USB directly without config any thing to my win7 system. After install complete, ubuntu installation software tell me to reboot.And everything is just find. While rebooting, there is NO UBUNTU system for me to select,and my laptop go straight to log in using WIN7. NO ubuntu shows on WIN7's configuration(Default System). Log in ubuntu using usb(try ubuntu without installation), I can find ubuntu's filesystem was already there. Formatting the disk on WIN7's disk management, rearranging them to other disk.Still having no trouble with WIN7. In the afternoon try a few times of installation and uninstallation of ubuntu. still shows no sign of selecting ubuntu system. In the evening another trial while installing ubuntu with the third option of: installing ubuntu alongside with INW7, erase win7 and install ubuntu. somethingelse --- my check failed with configuartion for what comes out with the 'something else' option,reboot. And I have no system now with some cmd tips say: Reboot and Select proper Boot Device or Insert Boot Media in selected Boot device and press a key. Files those on win7's orginal file system and Ubuntu filesystem can still be found when I 'try ubuntu without installation'. 5.But I just got no OS when I reboot my laptop normally.

• Grub2 attempting to boot hd1 when it should boot hd0

  - by JoBu1324

  I'm attempting to perform a "normal" install on a USB3 SSD (I don't know if it is noteworthy, but I don't have a swap partition). The installation proceeds normally (I'm installing from a USB2 device I created using LiLi Boot, with a copy of Ubuntu 12.10 64bit that I downloaded directly from the source. The system I'm running Ubuntu on has had a more traditional installation of ubuntu running on it without issue (also 12.10), so I know that everything works A-OK when booting from a 7200RPM internal disk. There are a number of oddities that I've noticed so far, including graphics corruption, but the first and most pressing issue is that Grub2 refuses to recognize the correct hd. From /boot/grub/grub.cfg: if [ x$feature_default_font_path = xy ] ; then font=unicode else insmod part_msdos insmod ext2 set root='hd1,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1 b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 else search --no-floppy --fs-uuid --set=root b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 fi font="/usr/share/grub/unicode.pf2" fi This is from a 100% fresh install of linux (first boot), which was installed while no hard drives were connected to the system, other than the USB2 LiLi drive. The system refuses to boot unless I change the hd1,msdos1 - hd0,msdos1 in the grub menu at boot, when it is the only disk device connected to the PC. What options are left for me to troubleshoot this issue? I've been racking my brains and taxing the internet trying to dig up something on this problem, but now I'd like to see if the Ubuntu community can rise to the challenge and help me fix this boot problem. This is the second time I've attempted this particular setup. The first time, after days of wasted time, I managed to get it to boot every other boot - i.e. every even boot it would boot into Ubuntu like it was happy; every odd boot it would boot into the BusyBox or Grub prompt. At one point it complained that it couldn't find /dev/disk/by-uuid/[the disk], which I found most perplexing, since the disk was there and booted before and after the occurrence (with intervention).

• What to do when 'dpkg --configure -a' fails with too many errors?

  - by rudivonstaden

  During an upgrade from lucid (10.04) to precise (12.04), the X session froze, and I have been trying to recover the upgrade to get a stable system. I have performed the following steps: Used ssh to log in to the stalled system over the network. Checked the contents of the /var/log/dist-upgrade directory. There was no activity on main.log, apt.log or term.log. top showed that process 'precise' was using about 3% CPU, but I could find no evidence that the upgrade process was still doing anything. 'dpkg' did not show up in top, but it came up with pgrep dpkg | xargs ps Killed the 'dpkg' and 'precise' processes Tried to recover the upgrade by running sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a. This was partially successful (some packages were configured), but failed with the message Processing was halted because there were too many errors. I ran the same command a few times, and each time some packages were configured but others failed. Tried running sudo apt-get -f install. It fails with similar errors to dpkg. The current situation is that dpkg --configure -a and sudo apt-get -f install fails with two kinds of error: Dependency issues, e.g.: dpkg: dependency problems prevent configuration of cifs-utils: cifs-utils depends on samba-common; however: Package samba-common is not configured yet. dpkg: error processing cifs-utils (--configure): dependency problems - leaving unconfigured Resource conflict, e.g.: debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable Additionally, it seems there's reference to potential boot problems, so I'm not keen to reboot without fixing the install first: dpkg: too many errors, stopping Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-3.2.0-25-generic cryptsetup: WARNING: failed to detect canonical device of /dev/sda1 cryptsetup: WARNING: could not determine root device from /etc/fstab So my question is, how to get a working install when dpkg --configure -a fails?

• ifconfig can't see USB wireless

  - by Alex

  I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

• Bluetooth mouse no longer paired after resuming from suspend since upgrading to 13.10

  - by Korakys

  Since upgrading to 13.10 from 13.04 my mouse no longer connects via bluetooth. In settings it states that the mouse is not paired. Restarting bluetooth with sudo /etc/init.d/bluetooth restart does not help. Restarting the computer does fix the problem if bluetooth is restarted also with the previously mentioned command, but this is not ideal. The mouse worked fine prior to updating to 13.10. The computer is a ThinkPad X230 with a Broadcom 'BCM20702A0' bluetooth module (I think).

• Intermittent sound on an Medion Akoya S5610

  - by ej159

  The sound on my machine (Medion Akoya S5610) works intermittently. If I reboot enough times I do get sound. This happened before I upgraded, when running Oneiric too. I have fiddled around with alsa-base.conf, putting in different values for model in options snd-hda-intel model=but still the issue persists (although I get the impression that I am more like to have sound on the next reboot if I have edited that file although I can't be sure of this). Adding index=0 does not help the situation either. I have been thinking that this problem could be related some how to the order that driver modules are loaded. The snd-hda-intel module is also used for the sound card (ALC888) in my graphics card. Could it be that these are some how competing? If so, how do I add a preference when they are using the same module? This is the result of lspci -nn | grep Audio (when sound was not working): 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) 01:00.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI RV620 HDMI Audio [Radeon HD 3400 Series] [1002:aa28] I've been wrestling with this problem for ages and ages and have spent days looking for answers on forums but to no avail so I would appreciate any help you can give. Many thanks

• SSD on USB 3.0 doesnt always mount

  - by juergen

  I would like to ask you for some support for this issue. The SSD I use is apparently slightly damaged. Atm it shows this popular Corsair Series 3 problem. symptom: the disk is working for some minutes and then just suddenly stops. Two months ago it worked like a charm. This was my boot device in these days. So now I still need to copy some data out of the device which leads me to my question. Usually the SSD is working again for some minutes, when i unplug and replug its power. It gets detected by the system again and I can continue my backup. The problem on Ubuntu is, that it is not recognized again after two or three replugs. I have to reboot to bring it back. To specify this situation: when i unplug and replug my USB mouse before i reboot it is not recognized as well. So something seems to be wrong with the system also. my question: how do i fix this rebooting issue? I will post all the logs you need to analyse. The problem doesnt depend on the interface. I tried USB3.0, 2.0 and Sata already. Thank you! cheers my system: Ubuntu 11.10, Gigabyte G41MT-S2P, Intel E6750 Corsair Force Series 2 - F120, Digitus USB 3.0 Adapter, USB 3.0 interface card

• Broken Package on Update Manager

  - by Widy Graycloud

  I dont know what's wrong with my update manager.. It says that the softwares that I installed was broken. Maybe because I force shutdown my laptop, because Ubuntu wont shutdown,showing up desktop wallpaper but not title bar and launcher, but It won't shut down (+that's another bug). I've just update the broken softwares. the size is 60 to 70 MB.. But It doesn't work. Now I cannot update or install any software from Update Manager or Ubuntu Software Center. Can anybody tellme what's wrong? This is what appears when I use Update Manager I use Ubuntu Software Center, and this message appeared I chose repair and when it update the broken softwares using Ubuntu Software Center. It failed. And show up this message. The problem is I can't update or install any program from Ubuntu Software Center and Device Manager anymore. (I closed allprograms include ubuntu software center,and device manager in this case). Some one helpme? I tried to use apt-get install -f in terminal but it shows message like this: E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

• How to handle the different frame rate on different devices?

  - by Fenwick

  I am not quite sure how frame per second works on a web page. I have a Canvas game that involves in moving an image from point A to B, and measuring the time elapsed. The code can be as simple as: var timeStamp = Date.now(); function update(){ obj.y += obj.speed; text = "Time: "+ (Date.now() - timeStamp) + "ms"; } The function update() is called every frame. The problem is that the time elapsed is different from device to device. It is pretty short on my PC, but get longer on my iPad, and is much longer on my cell phone. I thought it is because the FPS is smaller on mobile devices, so instead of calling update() every frame, I call it every 1ms by using a setInterval. But this does not solve the problem. In my understanding, the function for setInterval is invoked based on the increment in system time, other than frame rate, so it should fix the problem. Am I missing anything here? If the setInterval function is called based on FPS, is there any way to get around with the FPS difference across devices? On a side note, I have sort of a "water simulator" on the same canvas. It involves in redrawing about 60 objects which can be 600x600 pixels for every frame, so it could be a frame rate killer. I am using Phaser.js but not really using much of its functionalities, if that helps.

• Computer Says No: Mobile Apps Connectivity Messages

  - by ultan o'broin

  Sharing some insight into connectivity messages for mobile applications. Based on some recent ethnography done my myself, and prompted by a real business case, I would recommend a message that: In plain language, briefly and directly tells the user what is wrong and why. Something like: Cannot connect because of a network problem. Affords the user a means to retry connecting (or attempts automatically). Mobile context of use means users use anticipate interruptibility and disruption of task, so they will try again as an effective course of action. Tells the user when connection is re-established, and off they go. Saves any work already done, implicitly. (Bonus points on the ADF critical task setting scale) The following images showing my experience reading ADF-EMG Google Groups notification my (Android ICS) Samsung Galaxy S2 during a loss of WiFi give you a good idea of a suitable kind of messaging user experience for mobile apps in this kind of scenario. Inline connection lost message with Retry button Connection re-established toaster message The UX possible is dependent on device and platform features, sure, so remember to integrate with the device capability (see point 10 of this great article on mobile design by Brent White and Lynn Hnilo-Rampoldi) but taking these considerations into account is far superior to a context-free dumbed down common error message repurposed from the desktop mentality about the connection to the server being lost, so just "Click OK" or "Contact your sysadmin.".
