• Just installed Ubuntu 12.04 - integrated speakers aren't working but headphones are

  - by Mat Elkan

  I've just installed Ubuntu 12.04 alongside Windows Vista. There were no previous versions of Ubuntu installed. My computer is a Sony Vaio all in one, with integrated sound card and speakers. I can't get any sound coming from the speakers, but if I plug headphones into the jack on the side of the computer and select "headphones" under "sound" in "system settings" I can get sound through them. I have been searching all day trying to find a fix but haven't had any luck. Any advice would be greatly appreciated. Thanks! Mat :-)

• How can I get my mysqld-swamped CPU under control?

  - by Shay Guy

  I was AFK for about 24 hours and came back to find gnome-system-monitor saying all four CPU cores on my laptop were running at full throttle. mysqld is taking up more than one full core; when I tried to end the process, it restarted with a new PID. Then there's ksoftirqd/0-3, which apparently has something to do with interrupts, but I can't tell from Google what I'm supposed to do with those four particular processes. They're taking up a quarter or more of my processor cycles. Then there's Chrome, but I can probably handle that on my own -- how do I cool down the other processes giving me problems?

• Ubuntu 11.10 Unity - all Windows decorations disappear after I maximize any window

  - by korda

  When I maximize some of the windows all decorations disappear (by all, I mean on all windows)... Is that common issue on Unity or I'm just unlucky to have some prone to that bug configuration? Anyone have idea how to fix this? EDIT: It won't fix after unmaximize. It seems like maximazing window simply crashes window decorator. Decoration isn't displayed for all existing windows and any new ones. Only way I found to fix this is to run compiz --replace (but this ruins current windows placement - all windows end up on same desktop). It happens almost every time I maximize window.

• Debugging OpenOffice crashes

  - by JD Long

  This is partly an OpenOffice question and partly a Ubuntu question. I'm running OpenOffice 3.2.0 and Ubuntu 10.04. I get frequent crashes of OO, especially the Calc app, although I get crashes in the word processor as well. They are very abrupt and accompanies by no warning or error message. I'm just typing away and then the app is gone. Sometimes I even end up thinking I'm typing in OO and discover that OO has crashed and I'm typing in whatever application was under OO. However, I can't reproduce these crashes on demand. They seem random. I can open the same file and do the same exact thing but it does not crash. In Ubuntu how do I trace, track, or diagnose these types of crashes? Is there software I can invoke to help diagnose? Can I start OO from a command prompt with debugging of some sort enabled? Note: if someone could add the tag OpenOffice, I would appreciate it

• Sharing samba-folder with root access

  - by Industrial

  Hi everyone, I have a staging server in my network running Ubuntu server 10.10, being my main development area. As I need to access the files in the Apache root from other computers in the network, I have setup samba with the following settings: [www] comment = Apache root www path = /var/www writable = yes force user = root force group = root On the host computer, running Ubuntu 10.10 desktop, I am trying to mount the drive with a bash file looking like below: #!/bin/bash sudo mount -t cifs //192.168.1.5/www /media/www/ -o username=myusername,password=mypassword,rw,iocharset=utf8,file_mode=0777,dir_mode=0777 What happens is that I get mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) thrown in my face whilst trying to execute the mount. I've done exactly the same, with exactly the same smb.conf & mount-bash file on another computer in my network, but this just wont work. What am I doing wrong? I am running out of ideas.

• I'm trying to install postgresql on 12.04, and it's just not working

  - by Pointy

  I've got a new installation and I'm trying to get Postgresql working. The database was installed and I started a restoration from a dump on another machine, but that ran into problems because I had forgotten to install the "contrib" package. I used "pg_dropcluster" to drop the old cluster so I could start from scratch, and that's when things went weird. The first manifestation of this was that /etc/postgresql was just empty. I uninstalled the postgresql package and reinstalled, several times, to no avail. Is there something I can do to figure out why apt is confused here? I've done this many times on many systems and never seen anything like this happen.

• Upgrade to 0.25, files served to uPNP devices cannot play

  - by David Buttrick

  I have a Sony BDP-S390 bluray & network player. I upgraded my Myth server to 0.25. When I browse to the Myth server, and try to play a recording, I get an error message about the file not being payable in the player. Interestingly, the files that i have recorded, and the videos that I have loaded into my Video volume group are .mpg or .mp4. The player shows the filetype that it thinks the file is in it's list, and it claims that these files are AVI files, however none of them are. They are all .mp4 or .mpg files. Thinking that that was just an optical illusion, I went ahead and tried to play a file, but I get an error about the file not being playable. First of all, is there something that I need to do to make the uPNP server know about different filetypes? Is it reporting AVI because it hasn't been told about MPG or MP4? Second, I'd like to help out some more here and collect some logging about the uPNP server in the myth server. I cant seem to find information on how to turn on logging, and there is no mythbackend settings file int /etc/default. Thanks very much.

• Banshee keeps copying the same music files to my portable player over and over

  - by Dave M G

  I have Banshee 2.6.0, and I connect my Android phone by USB to sync my music collection of about 1500 songs. For the most part, it works reliably. However, on every sync, it deletes, and then recopies the same 62 songs each time. After that, everything works, and the sync completes successfully. As far as I can tell, these 62 songs are mostly recent additions to my collection, but not all of them, and I can't see any other commonality of significance. This is only a problem because the transfer speed when working within Banshee is quite slow, so this is eating up time. Sometimes I need to make a transfer and go, but I can't, because I'll have to wait for progress bars take their sweet time. I have tried to completely clear out the music files on the phone and resync. I have tried rescanning the music collection. What do I do to fix this irritation?

• Dropbox icon dissapears right after login

  - by garvamel

  Even though Dropbox's app indicator dissapearing from the tray area seems like a recurrent enough problem, my issue is a litte different. When I login, I can see the app panel populating, and the dropbox icon does indeed appear (config'd as startup application), but after some other icons show up (bluetooth, battery, etc.) it's gone. It's still running though. I'm guessing it's having issues with staying pinned, and I don't know how to start addressing this problem. I have tried many if not all solutions provided here in the forums for the "icon missing" questions. So far: I've whitelisted everything regarding panel Uninstalled-reinstalled (with and without rebooting in between) Overwritten current installation Purged installation from terminal Installed from Software Center and from .deb file batch deleted every "dropbox" ocurrences from terminal (files and folders) and reinstalled Ran sudo apt-get install libappindicator1, it installed, but didn't solve anything I'm on Ubuntu 12.04 LTS - 64 bits. Any insight would me much appreciated!

• sudo: unable to resolve host ubuntu-server

  - by Manfred Van de Waarsenburg

  I have a problem with sudo. Every time when I trying to use sudo I got this problem: sudo: unable to resolve host ubuntu-server My /etc/hosts file: 127.0.0.1 localhost 127.0.1.1 ubuntu-server # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes FF02::2 ip6-allrouters /etc/hostname gives: ubuntu-server I think there is some other setting that causes the unable to resole host, but I cannot find these.

• OpenJDK default options to always use the server VM

  I got a warning message: jvm uses the client vm, make sure to run java with the server vm for best performance by adding -server to the command line In fact, when i run java -version i get: OpenJDK Runtime Environment (IcedTea7 2.3.2) (7u7-2.3.2a-0ubuntu0.12.04.1) OpenJDK Client VM (build 23.2-b09, mixed mode, sharing) How does one go about and change OpenJDK's defaults to always start under the server VM?

• 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.

• ProStar gaming laptop, which had Ubuntu 10.10, won't boot past Grub. Thoughts?

  - by Richard Zak

  At work we have some high-end gaming laptops we use for their dual GPUs. The machines have second generation i7 CPUs, and came with Windows 7. On most of them I installed Ubuntu 10.10, and all was fine. There were two laptops that I wanted to repurpose and wanted to reinstall the OS. It boots the CD (burned Ubuntu installation CD, I've tried 10.10, 11.10, and 12.04, as well as CentOS 6), and when Grub tried to boot the kernel, I just get a cursor blinking in the upper left corner of the screen. I tried the disabling of ACPI and the other items in the advanced menu, but nothing works. I could still boot to the current Linux installation though. I was able to install Windows 7 again, and use WUBI, but I think that works because it uses the Windows bootloader and not Grub. How could it have worked before and not now? I have confirmed that the CD is fine, as are the hard drive and CD drive. I also had the same problem with Debian, and had to boot through Windows 7 to install it.

• How can I repair a corrupt kernel if no others are installed?

  - by Willi Ballenthin

  I've been running Ubuntu 10.04 on my laptop for quite some time. When I went to boot it up this morning, BAM! kernel panic (which immediately lead to human panic) when loading the kernel. So I've spent much of the day troubleshooting, and my current theory is that the FS is fine, but that the kernel image may be corrupt. Let's go with this current theory for the sake of this question, as I am interested how it is done. How can I replace the kernel image if I have no bootable kernels? Can I boot to a 10.04 live CD, copy the the vmlinuz-2.6.3x... to the HD and go from there? Wouldn't I want to copy the initramfs as well, but configured for the desktop system? Can I generate this from the live CD?

• Ubuntu won't boot and it is stuck on the loading screen

  - by Jordan March

  I had just installed it as dual boot 2 days ago, and everything was fine. I was installing some programs (i think it was Play On Linux) and I don't think the install was 100% done when the battery died. Since then it won't boot into Ubuntu; it just stays at the loading screen. I did make separate partitions for boot root home and swap. Can anyone help me get it back and running again? Even if I have to reinstall it. I just don't want to go back through getting all those apps. I'm running Ubuntu 12.10 64bit on a Acer Aspire 5750 core i3 cpu 4gb ram

• Problem with installing Nvidia display drivers on Ubuntu 13.10

  - by Pascal

  Hello everyone and thank you for taking a look at this topic! I'm currently trying out Ubuntu 13.10 but I keep hitting a wall when it comes to installing a driver. I've tried: sudo apt-get install nvidia-current This resulted in a un-bootable system. The screen just stayed black and the cursor displayed as an 'X'. After that I did had to re-install Ubuntu. The computer I'm using is an Acer-Aspire-V3 with a build in Nvidia geforce GT 630M and also with a Intel HD graphics chip-set (not sure if chip-set is the right word here). "lspci | grep VGA" output: pascal@pascal-Aspire-V3-571G:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1) I've searched a bit here and there and found out that it would be wise to mention that this laptop is using (or so I think) Nvidia Optimus, not sure if it will add anything to the subject but at least I'll mention it just to be sure. Now to the questions: Q1 How is this caused and how can I fix it? Q2 What additional information could I provide to help you help me?

• Lubuntu 13.10 selected LX games desktop now can't login

  - by user111667

  I logged out of my normal desktop and selected LX games from the dropdown list and logged back in. This led me to a black screen and now I can't see the login screen in order to change back to my normal desktop. On startup the machine boots normally, the lubuntu splash screen shows up, then it goes to a black screen with nothing on it - not even a mouse cursor. I can bring up a terminal using ctrl+alt+F2. Is there a way via terminal to change my desktop environment back to its previous state? Or alternatively, is there a file I can edit where my preferred desktop is stored? (The machine is dual-booted so I can access the Lubuntu files from LXLE which is installed on a second partition). The machine in question is a Toshiba A200 laptop.

• Wireless BMC4311 driver install

  - by user113910

  Exasperated with Ubuntu 12.04 and BCM4311 driver. HP2133 (was SUSE 10) Installed 12.04 in March. It ran well until November with no updates) then updates killed my wireless controller. Trolled forums & other for fix. Tried sudo -apt-get ing & gedit ing. Finally got it working (on full update with STA driver) Hwew!—thought that was it, only to fail again after 3-4 days. Tried all the fixes again but sudo -apt-get ing & gedit ing does not fix. I'm not without experience either: first 'boot-loader' I/P from 20 switch panel, seq to 4096 bit core-store: run to I/P larger processes from paper tape reader. Gone thru acoustic-coupled networks-to-billboards (before 'the net') pre-DOS, DOS, Windows 3.1 & all the others. This is a tough problem. Any advice?

• Can't install any Linux distro

  - by rstreeter78

  I have been trying to install Ubuntu on my step-son's netbook and I checked and his hard disk seems to be failing and i keep getting an error message that Ubuntu is unable to install due to hard disk failure. I was wondering how and if it is possible to install Ubuntu on this hard disk without it giving me an error message. I have tried the alternate install disk image and the regular desktop image and get basically the same error message. Is there a way to somehow override this and get it installed

  I have the following sudo config entry which I added via sudo visudo: mark ALL = NOPASSWD: /usr/bin/lxc-ls* I can run lxc-ls with my user fine but I can't append any parameters without it demanding I prefix the command with sudo. $ whoami mark $ lxc-ls test-container $ lxc-ls --fancy lxc-ls: error: You must be root to access advanced container properties. Try running: sudo /usr/bin/lxc-ls Any idea how I can edit via sudo visudo to allow for any argument after the command? I don't want to prefix the command with sudo as I'm using a python library to execute the command and it's being funny about sudo prefixes.

• How to run a file with sudo without a password?

  - by John

  I've made a script that preforms various system tasks, that I run regularly, but I have to use sudo to run the script, despite the fact that I own it because it runs root privileged commands. How can I add make sudo let me run this one file without having to enter my password every time I run it? I know that there are questions regarding running commands without a password, but I wasn't able to find one on running a file without a password. I am aware of the security risks, but I'm at home on a computer that I trust.
