• /etc/network/interfaces doesn't always take affect

  - by user1221444

  For some reason my eth0 does not have internet on reboot sometimes. I am using a static ip. I can ping my gateway, but I am unable to ping dns servers, or anything out of my network. It seems that when my internet does work(Usually but just restarting enough times), my /etc/resolv.conf has a nameserver in it. It is empty when I have no internet access. I believe something is overwriting my interfaces settings sometimes on boot. Any help would be appreciated. I am running Ubuntu Server 12.04 64bit /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 173.213.192.234 netmask 255.255.255.248 network 173.213.192.232 broadcast 173.213.192.239 gateway 173.213.192.233 dns-nameservers 8.8.8.8 auto eth1 iface eth1 inet static address 10.0.0.106 netmask 255.255.255.0 gateway 10.0.0.1

• Getting "boot error" when trying to boot from USB

  - by Jon Ball

  I'm wanting to try out Ubuntu, so followed the instructions for how to install Ubuntu onto a USB. I downloaded the .iso file, then the pendrivelinux 3 part process to make the USB bootable. I can see what looks like a full list of files on the USB (including the wubi.exe application and the syslinux folder). When I try to restart the computer with the USB in, I get the Dell start up screen, and then a black screen with "Boot Error" in the top right hand corner. Setup options (default) are to boot from Removable Device, then Hard Disc. USB is brand new, straight out of the packet. Computer: Dell Inspiron 530S BIOS: 1.0.13 OS: Windows Vista Home Edition USB: EMTEC 8Gb, formatted to FAT32 I've tried some of the tips in other help topics (holding down CTRL key while restarting, removing all other USB devices). I tried to reformat the USB to something other than FAT32, but my only other options were NTFS or exFAT (not FAT16 which was suggested in another topic).

• Blank Processes (?) in Natty Narwhal

  - by A Hylian Human

  I've noticed that there a seemingly blank processes (no process name, no cmdline info, only an ID), which also appear to cause my CPU to be running like crazy. My fans are going pretty much full speed and I have no idea what to do. Restarting does not help. Whenever I try to kill the process IDs, nothing happens. It's like new blank processes are continuously being created. I am really surprised that I am able to write up this question without Firefox lagging like crazy (and trust me, it's not Firefox causing the issue, as far as I can tell).

• Why does sound stop working after a while?

  - by badp

  I don't know how to reproduce this problem, because I don't regularly play music or sound. All I know is that, sometimes, I'll load a video (from youtube or from a local file) and there will be no sound. Everything looks fine software wise: Rebooting always fixes. aplay, paplay and pals give no error message I'm not in the audio group, as advised The device exists and appears in use: $ lsof /dev/snd/by-path/pci-0000\:00\:1b.0 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME pulseaudi 17313 badp 23u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 pulseaudi 17313 badp 30u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 Restarting pulseaudio or alsa seems to do no good. What is wrong here?

• VS2010 crashes when opening a vsp generated using VS 2012

  - by Tarun Arora

  I recently profiled some web applications using Visual Studio 2012, a vsp (Visual Studio Profile) file was generated as a result of the profiling session. I could successfully open the vsp file in Visual Studio 2012 as expected but when I tried to open the vsp file in Visual Studio 2010 the VS2010 IDE crashed. As a responsible citizen I raised bug # 762202 on Microsoft Connect site using the Microsoft Visual Studio 2012 Feedback Client. Note – In case you didn’t already know, VSP generated in Visual Studio 2012 is not backward compatible. Please refer below for the steps to reproduce the issue and the resolution of the connect bug. 1. Behaviour and Steps to Reproduce the Issue Description I have generated a vsp file by using the Visual Studio 2012 Standalone profiler. When I try and open the vsp file in Visual Studio 2010 the IDE crashes. I understand that a vsp generated by using VS 2012 cannot be opened in VS 2010, but the IDE crashing is not the behaviour I would expect to see. Steps to Reproduce the Issue 1. Pick up the Stand lone profiler from the VS 2012 installation media. The folder has both x 64 and x86 installer, since the machine I am using is x64 bit. I have installed the x64 version of the standalone profiler. 2. I have configured the system path by setting the 'environment variable' path to where the profiler is installed. In my case this is, C:\Program Files (x86)\Microsoft Visual Studio 11.0\Team Tools\Performance Tools 3. Created a new environment variable _NT_SYMBOL_PATH and set its value to CACHE*C:\SYMBOLSCACHE;SRV*C:\SYMBOLSCACHE*HTTP://MSDL.MICROSOFT.COM/DOWNLOAD/SYMBOLS;\\FOO\BUILD1234 4. Open up CMD as an administrator and run 'VSPerfASPNETCmd /tip http://localhost:56180/ /o:C:\Temp\SampleEISK.vsp' 5. This generates the following message on the cmd       Microsoft (R) VSPerf ASP.NET Command, Version 11.0.0.0     Copyright (C) Microsoft Corporation. All rights reserved.     Configuring and attaching to ASP.NET process. Please wait.     Setting up profiling environment.     Starting monitor.     Launching ASP.NET service.     Attaching Monitor to process.     Launching Internet Explorer.     The profiler is attached to ASP.net. Please run your application scenario now.     Press Enter to stop data collection...   6. I perform certain actions and then I come back to the cmd and hit enter to shut down the profiling. Once I do this, the following message is written to the cmd, Press Enter to stop data collection... Profiling now shut down. Report file "C:\Temp\SampleEISK.vsp" was generated. Running VsPerfReport, packing symbols into the .VSP. Shutting down profiling and restarting ASP.NET. Please wait. Restarting w3wp.exe.   7. I look in the C:\Temp folder and I can see the SampleEISK.vsp file generated. I can successfully open this file in Visual Studio 2012. 8. When I am trying to open the vsp file in VS 2010 the VS 2010 IDE crashes. Kaboooom! What I would expect to happen I expect to receive a message "VS 2010 does not support the vsp file generated by VS 2012". What actually happened The VS 2010 IDE crashed 2. Resolution This is a valid bug! However, there isn’t much value in releasing a hotfix for this issue. Refer below to the resolution provided by the Visual Studio Profiler Team.  Thank you for taking the time to report this issue. We completely agree that Visual Studio 2010 should not crash. However in this particular case this is not a bug we are going to retroactively release a fix to 2010 for at this point. Given that a fix would not unblock the scenario of opening a 2012 created file on Visual Studio 2010, and there is not an active update channel for Visual Studio 2010 other than manually locating and installing hot fixes, we will not be fixing this particular issue. Best Regards, Visual Studio Profiler Team   Though it would be great to improve the behaviour however, this is not a defect that would stop you from progressing in any way. It’s important to note however that VSP files generated by Visual Studio 2012 are not backward compatible so you should refrain from opening these files in Visual Studio 2010.

• Changes to 'resolveconf' discarded when connecting to a new network

  - by sudheer

  I have upgraded to 12.10 from 12.04 recently and I am having issues with connecting to the Internet. I got an IP address and am able to ping other LAN IPs in the local network but I am unable to connect to the Internet and am even unable to ping www.google.com from a terminal. Somehow making changes in /etc/resolv.conf and restarting resolvconf service and rebooting works but I need to do this every time I connect to a new network. How do I make these changes permanent? Can someone suggest a solution to this issue?

• Why do I get a blank screen when starting Wubi?

  - by August Guillaume

  I used Wubi to download 12.04 on a new partition. When restarting, the computer (Levono windows 7 -64) froze with no signal on my screen. Turning the computer on and off I received the option to sign in on windows or ubuntu. Windows worked well, but Ubuntu seems to bomb again as before. I can look at the new partition where some Ubuntu files exist via Windows explorer. What am I to do? Is 12.04 compatible with windows 7?

• Can't load any applications

  - by oshirowanen

  After installing Eclipse, I wanted to try to enable the global unity menu for Eclipse. Following a guide on the web, I was to make a change to: sudo nano /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so by changing Eclipse to Xclipse. After making that change, and then running sudo ldconfig. and even restarting, I can no longer open any application. I just see the application appear on the screen for a split second and then it disappears. So far I have noticed that I can no longer load Eclipse and Chrome. Anyone know how to fix this? I have tried changing Xclipse back to Eclipse and running the command sudo ldconfig, but it makes no difference.

• failing to boot after ''succesfully'' restoring from deja dup backup

  - by Jake

  Before upgrading to 12.04, I completely backed up 11.10 oneiric with deja-dup. In 12.04 I had major nvidia-related problems, so I decided to roll back to 11.10. I tried to restore from the backup and at first failed several times with "an uknown error occured". I reformated my hard drive, installed a fresh copy of 11.10 on the hard drive, and tried the restore again, with no success. I then booted from a live usb and ran the restore again after mounting the file system. I chose the restore location to be "file system" and the restore completed successfully, or so it said. After restarting my PC, all I got was a 'no operating system' error. I remounted my partition chrooted and installed the kernel. I am working now but my question concerns the restore. Why didn't the restore worked? I'm hoping someone has thought of something that I have not.

• Keyboard freezes when xorg crashes

  - by gsedej

  Situation is like that. Many times has happened that Xorg freezes and with it also keyboard. Quite some times because of some Compiz effects or Flash (fullscreen switch). Keyboard becomes totaly unresponsive, while mouse still works (I can move cursor, but can't click since desktop freezes) and music still plays and I can connect trough ssh. This is the only way I know I can try to solve problem - either by killing browser&flash or lastly restarting xorg server. This problem appears on more than one Ubuntu computer. My home dekstop with proprietery nvidia driver, on my work where I use noveau driever (opensource driver for geforce) and sometimes (but rarely) also on laptop with ATI graphics (using r300g driver which is really good!). Can someone explains why mouse still works while I can't input from keyboard? (I can't switch to virtual console or do R-E-I-S-U-B command) I have USB keyboard and USB mouse.

• Flashing task bar(firefox) in lxde panel and ubuntu internal error

  - by arroy_0209

  I have upgraded from ubuntu10.04 to 12.04 and installed lxde. The panel is now customized according to my convenience. The problem is there was a default checked option for "Flash when there is any window requiring attention" in Task bar(window list) and now when I run firefox, at times the concerned bar in the panel window list starts flashing but it is not clear exactly why at that moment firefox requires my attention. Normally this happens after I download some files (pdf files) and keep using firefox. The only solution I have found is to quit firefox and even after that I receive this message "Sorry, ubuntu12.04 has experienced an internal error. If you notice further problems, try restarting the computer." As usual I report the detailed message to ubuntu as suggested and finally restart the computer. So there are two problems, first, exactly why firefox needs my attention at times and second, why immediately after this, ubuntu experiences an internal error. Please suggest what I should do.

• thunderbird-bin causing CPU (core) lockup (12.04, 64bit, up-to-date)

  - by david6

  I have experienced 2-3 unexplained lockup over last 10 days. Today, I had a random lockup (no mouse, keyboard response, 100% CPU). But, when I finally switched (Ctrl-Alt-F1) to command line (it took several minutes) it told me that thunderbird-bin had locked a CPU. I ran this to resolve: pidof thunderbird-bin sudo kill #### However, after saving other work, I tried restarting Thunderbird. It went to 90%+ CPU, and within 20 seconds it locked again. Once I have more detail I will raise a bug (on Ubuntu Forums). Does anyone have any other suggestions, advice?

• brother MFC-J435W wireless scanning issue

  - by ogreen32

  Thanks for taking the time to read this. I have a brother MFC-J435W and I was able to get the printer set up for wireless printing, but it is not allowing me to scan wirelessly. It gives me the message to "check connection". I'll tell you what I've done so far and maybe someone can help me out. I've installed the scanner driver and scan tool I installed Xsane (to see if it would allow the scanner to communicate with the computer and that didn't help). I've tried restarting the computer. After those things I am now at a loss as to where to go from here. Any help would be great. Thanks. I've also searched for this question in the Brother FAQ as well as on here and I haven't found an answer. Thanks again.

• Up, down, right arrow keys and delete key not working

  - by user210780

  I have already read Delete and arrow keys not working and tried what is written there. I have also tried restarting my computer. I have also searched elsewhere for answers, but I haven't found any solution. I am using Ubuntu 12.04, and there were not problems yesterday, but for the last hour, I've had the following problem. When I press the up or the right arrow, nothing happens. When I press the down arrow, it doesn't make anything go down, but something appears in the upper right corner of my screen: http://i.imgur.com/pmnFOCD.png When I press the delete key, nothing gets deleted, but something appears in the upper right corner of my screen: http://i.imgur.com/Wu9czel.png The left arrow still works.

• Menus and text boxes look graphically corrupted in 12.10

  - by Stanton.Sculpture

  If I let my computer run long enough the screen gets glitchy or graphically corrupted only in certain areas i.e. in text related boxes, menus, menu bars, scroll bars, the system monitor window, etc. It becomes difficult to read what I am typing. Its been happening quite often and I can only fix it by restarting the computer, but its only a matter of time before it happens again. Don't know what else to do, its been a thorn in my side for quite some time now and I need a fix soon because its only gets more frequent until I'm rebooting my computer five times a day. I attached a picture of what happens to this bug report: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1083474 I know I can repeat this bug but I don't know how to catch it and document it. Any help would be greatly appreciated. Thank you

• Unbuntu stuck at boot after update

  - by RandomUbuntuUser

  Well, I installed Ubuntu 11.10 via Wubi on my MSI U270. Everything was running fine, I even got fglrx working after I manually downloaded a .run and executed it. Then I thought of running the complete updates that were on the update manager. I did run it, it took a whole night to complete, I waited a bit as the part came where I had to click on "Restart now". I clicked it, after that I'm stuck at the purple screen with all dots lighted orange. I've been waiting for it to start up for more than half an hour, and there used to be occasional HDD blinks which isn't happening now. Should I reboot? Edit: After the restart not while restarting, forgot to mention that and by the way, is there a way to see anything that's happening just so I know that it ain't stuck?

• Dash doesn't recognize that application is installed

  - by Calixte

  I've installed Geary from the software center, but I can't launch it from the Dash nor did I manage to create an app icon on the Launcher. The Software center has no problem seeing that the app is installed (see screenshot) Running the command "geary" will launch the app. Is there any way I can force the Dash to function properly? Thanks, Calixte PS: Does anyone know what this problem is related to? I tried re-installing the app and restarting the computer but that has no effect at all. I have practically installed nothing on this computer, so I can't imagine what app could interfere with the Dash

• ubuntu 12.10 graphic does not works correctly

  - by Amin

  I have installed Ubuntu 12.10 but my graphic does not works correctly. I used this command to installation: sudo apt-get install fglrx fglrx-amdcccle fglrx-dev But after the restarting my system, the side panel and upper one does not appear any more! I guessed it maybe that I used some incompatible packages so I removed the graphic card driver by this command: sudo apt-get purge fglrx fglrx-amdcccle fglrx-dev and tried it from graphical way from system setting > Software Sources > Aditional drivers and choosed the second option then applied change. But the resault waas such as before way!! I belive it is because of the Ubuntu does not know my graphic card. I am using VAIO VPCEA2TGX (N/A) and my graphic cart version is Mobility Radeon HD 5400 Series if it is matter. So now what is the exact problem and what I have to solve this?

• How to fix Bluetooth Sound in Ubuntu 11.10

  - by Cerin

  Bluetooth sound worked perfectly for me in Ubuntu 10.04. I recently upgraded to 11.10, and although sound in general works fine, Bluetooth sound almost never works. My headset is paired, and Sound Settings shows it's selected as the output device, but no sound is being output. I've tested the headset with other devices, and confirmed it still works, so the issue is definitely with 11.10. I'm not seeing any explicit errors and I can't find any similar issues with 11.10 through Google. I tried restarting the bluetooth service, but that had no effect. What can I do to fix this?

• How do I fix Flash player in Chrome 20?

  - by r0ckarong

  I just updated to Chrome 20.0.1132.43 which includes Flash 11.3.31.109. Since that update most of the flash videos I watch online will randomly display erratic behavior (skipping like a broken CD, "fast forwarding" at twice the frame rate with the audio being scrambled due to too fast playback, restarting every video after two seconds, fullscreen overlay being displayed but no image, fullscreen taking several seconds to actually show a picture, youtube player to go fullscreen but then hang in the controls fadeout animation with no picture -sound keeps playing). Is there anything I can do to resolve or work around this? I'm using Ubuntu 12.10 64Bit and the latest nvidia-current drivers 295.40 on a Geforce GT 440. It used to work in previous versions of Google Chrome.
