• How do I run a 64-bit guest in VirtualBox?

  - by ændrük

  I would like to have an Ubuntu 11.04 64-bit test environment. When I try booting the Ubuntu 11.04 64-bit installation CD in VirtualBox, the following message is displayed by VirtualBox: VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot. Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of your host computer. What am I doing wrong? Details: VBox.log, ubuntu-test.vbox, and /proc/cpuinfo. Kernel: Linux aux 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux The Virtualization setting in the BIOS is set to Enabled.

• Vdpau performance in Precise with Unity 3d

  - by bowser

  vdpau seems to be broken in Precise under Unity 3d. CPU usage ranges around 50-70% for 1080p movies while same movies utilizes around 5-10% in Natty with vdpau enabled (under Unity3d) The card is Nvidia G105m. It doesn't seem to be a Nvidia driver problem because in gnome-shell everything works as expected and I have tried different versions of Nvidia drivers (295.20, 295.33, 295.40 and the latest 302.XX from xorg-edgers) The results are all the same, works in Gnome Shell but not in Unity 3d. Disabling syn to vbank works if movie is not in full screen mode, but it doesn't work for full screen. I have searched around and haven't found much info. I am wondering if others are experiencing the same problem and if there are some known work around that I have missed. Unity 3d is otherwise very nice in Precise, but this is a show stopping issue for me (literally). Thanks. I have filed a bug here https://bugs.launchpad.net/unity/+bug/993397

• missing libjpeg.so.62 from ia32 shared library

  - by user170200

  I am trying to install a chemical/molecular biology modeling program called Molsoft ICM-Pro. Initially after downloading the program and trying to open, it gave me error messages that I was missing shared libraries, and after talking with my network administrator he recommended I install the ia32 shared libraries using sudo apt-get install ia32-libs Which gives sudo apt-get install ia32-libs Reading package lists... Done Building dependency tree Reading state information... Done ia32-libs is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. so I am assuming the libraries installed correctly, but now when I try to run the program I get this error: ubuntu:/home/reilly/icmd icm icm: error while loading shared libraries: libjpeg.so.62: cannot open shared object file: No such file or directory So my question is, where can I get the library containing libjpeg.so.62? Additionally, I was told I would need libXmu.so.6 and libtiff.so.3 . Is there a shared library that could be missing that would contain these files? I am an ubuntu noob, so sorry if the information I provided was unclear. Any help would be immensely appreciated! btw I am using ubuntu 12.04 dual boot with windows on an HP pavilion dv6

• Lubuntu 13.04 mysterious occurence of icons appearing to be dragged

  - by Jimmy

  On Lubuntu 13.04 every now and again, it appears as if an icon or file is being dragged across the screen...sometimes very short distances, sometimes longer. It seems to happen a short while after moving around Desktop icons. One or more mock drag and drop operations are visible. It's almost as if the actions are being replayed. What could be causing this? Is this a know issue? (Using nvidia-310-updates driver if any help). Any input would be much appreciated! Thank you Jimmy

• Kubuntu login problem

  - by Balázs Mária Németh

  I have a problem when trying to login to my Kubuntu 10.10. The login screen shows up, then I type my password, a blank screen is shown with my desktop background picture and then throws me back on the login screen. if I choose to login from console, I can do that, and by typing startx I can log in just fine but in the end I cannot shutdown the computer from the k menu nor will my settings remembered for the next time I log back. I have my home directory mounted from a different partition but I tried to create a new user account and I could log in without any kind of problem. The home directory is not encrypted, at least not to my knowledge. Some log files: Xorg.0.log dmesg.out kdm.log xsession.errors

• System blacks out when resuming on opening lid

  - by Ashfaq

  It is happening now and then but frequently these days. My system E420 Lenovo Thinkpad running 12.04 LTS blacks out and doesn't respond when woke up from sleep by opening the lid. I then have to forcibly press the Start button and restart the entire system which is creating a headache for me. Please suggest a way to overcome this problem. Main characteristics leading to this that I have noticed are: When a video is paused before I suspend the system When Eclipse or pgAdmin is running before suspending the system

• How can I get Kubuntu to use my Multimedia keys

  - by tbruf13

  I have tried to get Kubuntu to use my multimedia keys, and I cannot figure out how to do this. This feature is default in Ubuntu and in Linux Mint. They just work. I have followed the KUbuntu wiki post on Multimedia keys. I tried to enable Multimedia maps with xmodmap. It did not work. I tried to use the KDE GUI and could not seem to make the function I wanted work. The functions I am trying to get to work are fn+F12 = skip song fn+F11 = previous song fn+F10 = stop fn+ F9 = play/pause. I know this is possible because it worked in Ubuntu and in Mint, but it does not work in Kubuntu. I have submitted a bug report on this issue. Disclaimer: I am using Kubuntu 12.04 I have looked at this post, but Is there a way to enable Ubuntu Keyboard shortcuts in Kubuntu? do not know what to call the keys in that program.

• Ubuntu Server Read-Only Filesystem Issue

  - by Scott Deutsch

  We are running a virtual machine server with multiple virtual machines with ubuntu server edition 12.04 and every so often (usually after updates via webmin it seems), the hard-drive turns into read-only filesystem. Only two of the virtual machines get affected by this problem (that I noticed so far). What could be causing this issue? What could we try to fix this problem? Has anyone else had this problem before? If so, what did you do to fix it? If I use Aptitude instead of webmin, it will not turn into into a read-only filesystem. Though this could be a coincidence. Could it be a webmin issue? Thanks. UPDATE 1 Looks like this is not an update/webmin issue at all. How I know this is because one of the virtual servers is a git server and it turned into a read-only filesystem out of the blue today. With this new info provided to you, what should I try? Thanks.

• How do I customize desktop wallpaper slideshow?

  - by Pithikos

  I spent some time and tried varioues things but nothing works. Here's what I have tried so far(changing the slideshow manually): Making a new folder /usr/share/backgrounds/mywallpapers and add my own background-1.xml in there. Copying a bunch of my own wallpaper files into /usr/share/backgrounds/ Copy /usr/share/backgrounds/Contest/background-1.xml to /usr/share/backgrounds/ I logged out and in and still no changes in Appearance app. I have heard about Wallch but I don't want some app running in the background all the time. I'm not even sure Wallch will work with Gnome 3. I also tryied gnome-3-wp (Gnome 3 Wallpaper Slideshow app) but it just seems broken for Oneiric Ubuntu 11.10. Anyone has a solution?

• Need Help Changing Owner of External HArd Drive

  - by Thomas Ballew

  My understanding of code is about zero. I can open a terminal window, and type commands that are given to me, but that's about it. If someone can help me with this question, and explain at a level I'm likely to understand, thanks. If not, thanks anyway. I have an external hard drive with two partitions. I bought this drive when my operating system was Apple, 10.5 or so, and it was formatted as HFS+ with that system. Now, connecting the HD to my Linux system, I can read files, but I have about 1.5 TB of space that I can't use, because I am not the owner of the file, so can't write to the HD. Short of reformatting the HD, is there a way for me to set the permissions for the HD so I can write to it? Again, thank you.

• Can I have a .desktop Launcher for both Python2 and Python3 depending on version installed?

  - by Takkat

  After very few issues only I moved my application from Python2 to Python3 making sure it will still run with Python 2.7, and hence has python = 2.7 as dependency only. This was mainly done because Python3, and some dependencies are not installed in a default 12.04 LTS, and I do not want my users to have to install all Python3 only to run my script. When I create an appname.desktop launcher I now need to decide if it starts my application using Python2, or Python3 like EXEC=python /path/app.py EXEC=python3 /path/app.py But what I would like it to do is to Launch the application with the Python3 interpreter if Python3 is installed. Otherwise use Python2 if Python3 is not installed. How can this be done? Do I need to tell it in my package installation script, or can I have a launcher which can handle both (in case people install Python3 after they had installed my script)?

• How to get D-Link DWA-547 working on Ubuntu 13.10?

  I got a D-Link DWA-547 Wifi card which is supposed to work out-of-the-box with Linux. Says so here: http://wireless.kernel.org/en/users/Drivers/ath9k/products/external While lspci does list the device, NetworkManager doesn't seem to allow me to configure Wifi. lsmod also shows that ath9k isn't loaded. Manually loading with 'modprobe ath9k' doesn't help. How do I get this card working on Ubuntu 13.10 64-bit?

• Dual-Boot Windows 7 and Ubuntu 12.04.1

  - by z3matt

  I installed Ubuntu 12.04.1 alongside Windows 7. I wanted to check out what it's all about. By the way, i actually like the interface a lot and the free office suite is very very nice. I love how they can save to the .docx as well. Onto the story: I installed it using this tutorial and I set it all up and everything and things were great. I used the EasyBCD 2.2 Tool and created an Ubuntu 12.04.1 entry and when I boot the computer the Windows 7 and Ubuntu 12.04.1 option show up. However, when I click Ubuntu it does not boot. It say and error and says I must put in the Windows CD to repair or something like this. Here's my system specs: ASRock Extreme4 (EUFI BIOS) Corsair Vengaence 2x4GB nVidia GeForce 9800GT i5-3570K 3.4GHz Corsair 620W Modular 500GB WD Caviar Blue I have no clue what could be wrong with it and I would love any assistance. I am willing to mess around and if something happens wrong I can just reinstall windows and it won't be a huge deal. Thank you very much! Here are my partitions I made: /boot 500MB / 10000MB /home 20000MB swap area 4000MB BIOS 4000MB

• How do you globally set the default browser using KDE4?

  - by wishi

  Hi! I'm using awesome-wm on Kubuntu 10.10. I like some of the KDE tools... like choqok. Thing is, that within awesome wm it seems to be impossible to set a default browser, because KDE4 settings overwrite the generally desired settings: To illustrate the problem: % xdg-mime query default text/html chromium-browser.desktop And from ~/.kde/share/config/kdeglobals [General] BrowserApplication=firefox.desktop Which does in no way make sense to me. If I set Firefox as default xdg-mime should not have Chrome. In fact I want Firefox. So how do I globally once and for all, across all frameworks, define Firefox as default? Best, Marius p.s.: I should probably mention, that clicking in Choqok starts Konqueror...

• Can't enable wireless lan on Fujitsu Siemens A1665G with Ubuntu 11.10 installed

  - by Theo

  I saw my old Notebook yesterday and wanted to make that work again. On Windows XP the wireless worked still fine. Then I installed new Ubuntu 11.10 32bit and I'm sadly not able to make the wireless enabled. [I replaced Win XP entirely] lspci lists following network: 08:0a.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) So after recommendation from this link I installed the b43 firmware module. iwconfig prints the following: wlan0 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associatd Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Power Management: off As you can see, my wireless lan adapter is not turned on. sudo iwconfig wlan0 txpower auto Doesn't change anything. Then I tried to make it work with rfkill. rfkill list 0: phy0: Wirless LAN Soft blocked: no Hard blocked: yes sudo rfkill unblock all rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes remains the same. The question is now, how I could enable the hard blocked wireless LAN. There is no hardware switch for wlan integrated. However there is a button to change the state. I always thought this would be software sided, but it seems to make some hardware changes as well... The wireless LED is also not blinking (as it did on windows xp) I reset bios and searched for some settings in there, but it has only a few options and nothing to do with wireless settings, nothing works here.. At last I tried to install the acer hotkeys but I was not able to manage that. I installed the acerhkgui package, but in initializing progress, it was not able to compile acer hotkeys for my machine. There was a message that asm/linkage.h was not found while compiling. Do you have any ideas what I could do to make this hard blocked stuff disabled and my wireless card work? PS: I also tried sudo rm /dev/rfkill and a reboot to reinit that stuff... No success :(

• build command by concatenating string in bash

  - by Lennart Rolland

  I have a bash script that builds a command-line in a string based on some parameters before executing it in one go. The parts that are concatenated to the command string are supposed to be separated by pipes to facilitate a "streaming" of data through each component. A very simplified example: #!/bin/bash part1=gzip -c part2=some_other_command cmd="cat infile" if [ ! "$part1" = "" ] then cmd+=" | $part1" fi if [ ! "$part2" = "" ] then cmd+=" | $part2" fi cmd+="> outfile" #show command. It looks ok echo $cmd #run the command. fails with pipes $cmd For some reason the pipes don't seem to work. When I run this script i get different error messages relating usually to the first part of the command (before the first pipe). So my question is whether or not it is possible to build a command in this way, and what is the best way to do it?
