• Sound is not working correctly on Ubuntu 12.04

  - by Jeggy

  I know this is my own fault. But what i did was this first i wrote this command 'sudo apt-get remove pulseaudio' and then i wrote again 'sudo apt-get install pulseaudio' and now the sound doesn't work properly And the Indicator doesn't work either, it's just grayed out. The shortcuts are not working either. Alsamixer is working, and this is the only way i change change the volume at the moment: jeggy@jeggy-XPS:~$ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xf1c00000 irq 52 jeggy@jeggy-XPS:~$ aplay -l **** List of PLAYBACK Hardware Devices **** ALSA lib conf.c:1686:(snd_config_load1) _toplevel_:11:0:Unexpected end of file ALSA lib conf.c:3406:(config_file_open) /etc/asound.conf may be old or corrupted: consider to remove or fix it /usr/bin/pulseaudio: error while loading shared libraries: libpulsecommon-1.1.so: cannot open shared object file: No such file or directory card 0: PCH [HDA Intel PCH], device 0: ALC665 Analog [ALC665 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 1: ALC665 Digital [ALC665 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 VLC sound is not working, am getting this error:

• How to find keycodes for Fn + keys in Ubuntu 11.10

  - by budwiser

  I'm trying to find out the keycode for Fn+? keypress (left arrow). Xev outputs FocusOut event, serial 36, synthetic NO, window 0x3c00001,    mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 36, synthetic NO, window 0x3c00001,    mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 36, synthetic NO, window 0x0,    keys:  4294967213 0   0   0   0   0   0   0   0   0   0   0   0   0   0   0              0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   If it is telling me the keycode here, I'm not able to interpret it so help would be appreciated. I'm also curious for finding out if it's possible to bind something to Fn+Del but when trying out this combination, Xev outputs KeyPress event, serial 36, synthetic NO, window 0x3c00001, root 0xad, subw 0x0, time 1984903, (-666,480), root:(53,533), state 0x0, keycode 119 (keysym 0xffff, Delete), same_screen YES, XLookupString gives 1 bytes: (7f) " " XmbLookupString gives 1 bytes: (7f) " " XFilterEvent returns: False KeyRelease event, serial 36, synthetic NO, window 0x3c00001, root 0xad, subw 0x0, time 1985008, (-666,480), root:(53,533), state 0x0, keycode 119 (keysym 0xffff, Delete), same_screen YES, XLookupString gives 1 bytes: (7f) " " XFilterEvent returns: False which is exactly the same as pressing del without Fn. So, summary for short How can I find keycode for Fn+? (left arrow)? Is it even possible to bind something to Fn+Del or am I facing windmills here?

• Ubuntu 12.04 suddenly will not boot after compiz crash on lockscreen

  - by schonjones

  Yesterday i went to work and closed my laptop. When i got home I couldn't get the lock screen to come back up. ctrl+alt+f2 to get to a terminal and Tried to kill compiz, compiz was not running so I tried to restart it got an error opening the display so i tried to restart lightdm again couldn't open display. so I restarted and now I am stuck on the loading screen. I tried booting in recovery mode and all options hang except root, but i'm stuck with read only. booting from a live cd I can mount the drive but again stuck with read only. I'm completely stuck here. checking my default-display-manager returns "/usr/sbin/elsa" as the only line and can't edit it. I've got an 11.10 live cd and my /home is encrypted so i can't try to back anything up at the moment either. How can i resolve this or at the least back up some of my data? Please help!

• Joining Two MKV files in Ubuntu?

  - by Ryan McClure

  I have an opera that I'm ripping to my computer in MKV format with Handbrake. This opera is on two discs. Is there a way to join the resulting MKV's together? They will have the same bitrate, resolution, etc. If I do this, can I keep chapters from both MKV files organized? And, since I have subtitles in the file (not burnt in), will they still stay intact? I'm not too sure if this question is off-topic or not. If it is, feel more than free to delete it. :)

• ubuntu 13.04 recognizes usb mobile broadband modem as ethernet connection

• Ubuntu 12.04 connected to wireless network but internet not working

  - by A.J.

  I can connect to my house's wireless network just fine, but when I'm connected I can't browse the web. Firefox starts connecting to a site and then just poops out.

• How to explain a layperson why a developer should not be interrupted while neck-deep in coding?

  - by András Szepesházi

  If you just consider the second part of my question, "Why a developer should not be interrupted while neck-deep in coding", that has been discussed a number of times by smart people. Heck, even the co-founder of SO, Joel Spolsky, wrote a blog post about "getting in the zone" and "being knocked out of the zone" and why it takes an average of 15 minutes to achieve productivity when participating in complex, software development related tasks. So I think the why has been established. What I'm interested in is how to explain all that to somebody who doesn't know beans about Beans (khmm I mean software development). How to tell the wife, or the funny guy from accounting at the workplace, or the long time friend who pings you on Skype every 30 minutes with a "Wazzzzzzup?!", that all the interruptions have a much deeper impact on your work than the obvious 30 seconds they took from your time. Obviously you can't explain it by sentences like "I have to juggle a lot of variable names in my short term memory" unless you want to be the target of blank stares or friendly abuse. I'd like to be able to explain all that to non-developers in a way that will make them clearly understand - without being offensive, elitist or too technical.

• How can a usb be detected but not show up anywhere?

  - by George Mauer

  I started the morning by trying to create a bootable usb using a 2gb stick and the startup disk creator. It seemed to run through the whole process just fine until it got to a screen that read something like "Creating memory partion" and which sat on 100% for about 45 minutes before I hit cancel and removed the usb stick. Now the usb stick is not being detected as storage or...anything (even on my windows pc) though it does show up in the syslog. Allow me to demonstrate. We start with the usb not plugged in: [georgemauer@ubuntu:~]$ sudo fdisk -l (04-04 16:01) Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x994bdc0f Device Boot Start End Blocks Id System /dev/sda1 2048 27650047 13824000 27 Hidden NTFS WinRE /dev/sda2 * 27650048 27854847 102400 7 HPFS/NTFS/exFAT /dev/sda3 27854848 976771119 474458136 7 HPFS/NTFS/exFAT I plug in the usb: [georgemauer@ubuntu:~]$ tail -f /var/log/syslog ***Snip*** Apr 4 15:01:18 ubuntu wpa_supplicant[1136]: WPA: Group rekeying completed with 00:24:36:ad:e7:3f [GTK=TKIP] Apr 4 15:02:29 wpa_supplicant[1136]: last message repeated 3 times Apr 4 15:02:29 ubuntu kernel: [22122.788133] usb 2-1: new high speed USB device number 13 using ehci_hcd Apr 4 15:02:29 ubuntu kernel: [22122.923873] scsi10 : usb-storage 2-1:1.0 Apr 4 15:02:29 ubuntu mtp-probe: checking bus 2, device 13: "/sys/devices/pci0000:00/0000:00:13.2/usb2/2-1" Apr 4 15:02:30 ubuntu mtp-probe: bus: 2, device: 13 was not an MTP device Apr 4 15:02:30 ubuntu kernel: [22123.926154] scsi 10:0:0:0: Direct-Access GENERIC USB Mass Storage 1.00 PQ: 0 ANSI: 2 Apr 4 15:02:30 ubuntu kernel: [22124.105118] sd 10:0:0:0: Attached scsi generic sg1 type 0 Apr 4 15:02:30 ubuntu kernel: [22124.108212] sd 10:0:0:0: [sdb] Attached SCSI removable disk but then: [georgemauer@ubuntu:~]$ ls /mnt -alF (04-04 16:02) total 8 drwxr-xr-x 2 root root 4096 2011-04-21 12:51 ./ drwxr-xr-x 26 root root 4096 2012-03-31 13:16 ../ [georgemauer@ubuntu:~]$ ls /media -alF (04-04 16:03) total 8 drwxr-xr-x 2 root root 4096 2012-04-04 12:18 ./ drwxr-xr-x 26 root root 4096 2012-03-31 13:16 ../ What could be going on and how do I recover my usb key?

• Ubuntu 11.04 does not detect my tata photon +

  - by nikhil

  I am trying to connect to the Internet via my photon+ from the past day and have tried various suggestions on the Internet and have tried to zero in to the main cause of the problem which is that my device is not detected. I have tried the following ways: 1) After connecting the device, I tried to create a mobile broadband connection via System Preferences Network Connections and selected tata photon plus. But there was no connection. 2) I did sudo apt-get install usb-modeswitch-data and sudo apt-get install usb-modeswitch But the prompt said that they are at their newest version. 3) I tried to edit the file sudo gedit /etc/usb_modeswitch.d/12d1:1446, but this file did not exist. 4) my lsusb output is nikhil@nikhil:~$ lsusb Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 003: ID 22f4:0021 Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 04f2:b159 Chicony Electronics Co., Ltd Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Any Ideas ??

• Ubuntu 14.04 has a bunch of old kernel directories

  - by NoBugs

  I saw in Disk Usage Analyzer I have 3.13.0-xx for 8 minor versions of the kernel in /lib/modules. Each is around 200MB. I remember having to go through in Synaptic and remove those old Linux versions before, but hasn't this bug been fixed? Is it just paranoid default setting, that perhaps all of the last half dozen kernels might become unbootable, so it keeps each old one around? Or do I have some developer setting enabled by accident that causes this?

• Boot existing ubuntu installation on uefi, GPT BTRFS

  - by user204720

  I have looked through many of the questions, and haven't found anything that quite satisfies this problem. I have an ssd hard drive that is bootable from my old computer. It is a standard BIOS, however, I built a new computer with Z87 motherboard that is a UEFI. What I'd like to do is boot from this hard drive without wiping out the hard drive. I've tried booting from legacy mode, doesn't seem to work. Part of the multitude of problems is my partitioning scheme, which is GPT. sdx1 is the btrfs system, sdx2 swap, sdx3 is bios_grub. I've tried setting the UEFI/BIOS to boot in legacy mode, I've tried turning my swap partition into a Grub EFI boot, I've tried copying the file system onto a new drive installed on the new system. However, copying the information doesn't keep the filesystem or subvolumes intact. I've also tried boot-repair which is when I overwrote the swap space. I'd really rather not start over on a new install, so any other suggested trees to bark up would be appreciated. For the record, I hate you Microsoft, and ASUS I understand complying with microsoft, but make it optional... I'm really disappointed in that I have to deal with Windows 8 when I have nothing to do with it. Something I think I could try, but would like to hear from more experienced users. Moving the sdx1 (btrfs /@/@home) partion and opening up a 100 MB partition on the beginning sectors and install efi compatible Grub2 installation. Would it work? How to move a partition?

  I wanted to install teamviewer on linux 64-bit system.

I emptied archives folder: sudo apt-get clean sudo apt-get update sudo apt-get upgrade Again I have problem installing my deb package. Is there anything I could do now to solve this problem? I've read the below article as well: Install Teamviewer using a 64-bits system but I get a dependency error EDIT: I found libperl5.14:amd64 as a broken package.

• Will BIOS boot mode Ubuntu install be able to boot when firmware "Fast Boot" is "Ultra Fast"?

  - by Pro Backup

  I have an AsRock mainboard with UEFI BIOS P1.50 02/14/2014. The firmware "Fast Boot" option is set to "Fast", Boot Option #1 is set to "AHCI P4: OCZ-VERT...": this is BIOS not UEFI boot. This boot disk has an MBR partitioning scheme (# parted -l | grep Partition\ Table:). Therefore Ubuntu 14.04 is installed in BIOS/CMS (Grub-PC) mode. The Ubuntu boot process ends in a text console (no GUI). There is no external graphics card in use. The stock Ubuntu kernel is replaced with Ubuntu supplied mainline 3.16.0-031600rc6-generic. dmesg outputs lines containing BIOS, like: SMBIOS 2.7 present Calgary: detecting Calgary via BIOS EBDA area Calgary: Unable to locate Rio Grande table in EBDA - bailing! [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored BIOS EDD facility v0.16 2004-Jun-25, 0 devices found The ASRock BIOS it selves display this help text for "Ultra Fast - Fast Boot": Ultra Fast mode is only supported by Windows 8 and the VBIOS must support UEFI GOP if you are using an external graphics card. Please notice that Ultra Fast mode will boot so fast that the only way to enter this UEFI Setup Utility is to Clear CMOS or run the Restart to UEFI utility in Windows. Assumptions: I suspect after changing UEFI setting "Fast Boot" to "Ultra Fast" that the machine will no longer boot into Ubuntu's console. I expect when first exchanging "Grub-pc" with "Grub-efi", that the machine will still be able to boot to a grub menu (thus allowing to change the "Fast Boot" setting back to "Fast" without clearing CMOS). Are these two "Fast Boot" assumptions correct, and/or, may I expect Ubuntu 14.04 running mainline kernel 3.16rc6 and Grub-efi to still boot to console after enabling UEFI Ultra Fast Boot?

• Boot from Ubuntu ISO on a hfsplus partition (macbook pro)

  - by user279771

  I would like to be able to boot from an ISO stored on an HFS+ partition (the main partition on my macbook pro). Here is what I've done so far: (writing in shorthand :D) grub> insmod hfs,hfsplus,loopback,part_gpt grub> loopback loop (hd0,gpt2)/location/to/img.io grub> configfile (loop)/boot/grub/loopback.cfg ... This does not work. tab-complete of the (loop) path does not work... However, this does work (tab-complete and all) if the iso comes from my ext3 partition. For particular reasons, I can't have the iso images on the ext3 partition, they need to be kept on the hfs+ partition. What should be done?

• Problem with the keyboard layout in Emacs (ubuntu 12.04)

  - by user61648

  I've got some problems with the keyboard layout. I have a french AZERTY keyboard. When I switch to another layout (I tested both programmer DVORAK and Greek) everything seems fine. However, in emacs, I have a more unexpected (at least for me) behavior. For example, in DVORAK, I thought to obtain: On my french Keyboard - DVORAK X - Q Alt-X - Alt-Q But I have: X - Q Alt-X - Alt-X When I press the Alt key, the layout change seems to be inactivated. I precise I didn't activated any shortcut containing the Alt key for the layout switching. Moreover, I'm not sure this behavior is restricted to Emacs, but I don't use shortcuts like Alt-... in another application. Is a such behavior normal ? And in this case, how can I use a shortcut like Alt-Q when I switch to DVORAK ?

• Why was libhal removed in Ubuntu 13.10?

  - by I-Jo

  After installing 13.10, I realized libhal was no longer a sudo apt-get install away... in fact it was no longer anywhere to be found (except in the Raring Repos). And installing libhal from the raring repos is not the best option. It is the best workaround for not having it. Why was it removed? Was it an accidental removal, or is it no longer going to be included in the repos, even in the next LTS? I ask because Amazon (and other services) require it to be installed.

• Ubuntu 12.04 - Unable to change brightness

  - by Raymond Standen

  So, as a number of users seem to be experiencing, I am unable to change brightness on my laptop. Using the Brightness and Lock in settings, the slider moves but brightness does not adjust. The fn keys work for volume but not for brightness. I have updated my drivers and installed all updates, however the brightness is still at maximum. I have heard that opening sudo gedit /etc/x11/xorg.conf and entering Option "RegistryDwords" "EnableBrightnessControl=1" can fix this, however when opening xorg.conf through Terminal I am greeted with a blank document... Not very reassuring. Toshiba L750 Laptop Nvidia Graphics Card Dual boot with Windows

• stud ubuntu howto?

  - by Matt H

  I've just been looking at the stud init script as I thought perhaps I'm meant to create a stud.conf inside /etc/stud However, in looking through the init script it would apppear that it loads stud.conf variables into the current environment. This of course fails for some reason and you get a bunch of errors. Worse still, stud source code doesn't work with environment variables. Can someone tell me how you're actually meant to set up stud with init script as it would appear to be completely broken. Maybe I can just disable the init script and call stud from rc.local?

• Bluetooth pairing of nokia with acer ubuntu 12.04

  - by Aneesh karthik C

  I have a Nokia 2700 classic phone. I tried installing obextool and Nokuntu. I run Nokuntu and find that every icon is enabled except for the Nokia Communication Centre, (it is greyed but is precisely what I need to be working!) I even tried connecting phone to laptop with a USB cable, and the same problem props up. I can also browse the contents of the phone as well as the memory card, in whichever way, either the Nautilus or Obextool file manager. The only issue that needs sorting is the communication centre.

• Customizing the NUnit GUI for data-driven testing

  - by rwong

  My test project consists of a set of input data files which is fed into a piece of legacy third-party software. Since the input data files for this software are difficult to construct (not something that can be done intentionally), I am not going to add new input data files. Each input data file will be subject to a set of "test functions". Some of the test functions can be invoked independently. Other test functions represent the stages of a sequential operation - if an earlier stage fails, the subsequent stages do not need to be executed. I have experimented with the NUnit parametrized test case (TestCaseAttribute and TestCaseSourceAttribute), passing in the list of data files as test cases. I am generally satisfied with the the ability to select the input data for testing. However, I would like to see if it is possible to customize its GUI's tree structure, so that the "test functions" become the children of the "input data". For example: File #1 CheckFileTypeTest GetFileTopLevelStructureTest CompleteProcessTest StageOneTest StageTwoTest StageThreeTest File #2 CheckFileTypeTest GetFileTopLevelStructureTest CompleteProcessTest StageOneTest StageTwoTest StageThreeTest This will be useful for identifying the stage that failed during the processing of a particular input file. Is there any tips and tricks that will enable the new tree layout? Do I need to customize NUnit to get this layout?

• Can't access Windos 7 OS in Ubuntu

  - by Myers

  When I try and Access my Windows 7 OS I get the following memo and I have no idea what to make of the code. Error mounting /dev/sda2 at /media/name/Windows7_OS: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda2" "/media/name/Windows7_OS"' exited with non-zero exit status 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. What should I do ?

• Who is likely to need the most this high-quality, measurable, reliable approach to software? [closed]

  - by Marek Cruz

  Software engineering is the application of principles of engineering to software. Trouble is, most of those who like to flatter with the title "software engineer" don't do that. They just keep writing code and patching it until it's stable enough to foist off on users. That's not software engineering. Who is likely to need the most the practice of software engineering? (with all the project planning, requirements engineering, software design, implementation based on the design, testing, deployment, awareness of IEEE standards, metrics, security, dependability, usability, etc.)

• upgrade from ubuntu 13.04 to 13.10 causes vmware workstation 9 problems
