  • How do I access my remote Ubuntu server via X-windows from my Mac?

    - by Magooda
    I have an Ubuntu server (12.04 LTS) running remotely on a cloud hosting service. I have installed ubuntu-desktop via apt-get: $ sudo apt-get install ubuntu-desktop It appears to have installed no problem. I have confirmed that /etc/ssh/ssh_config on the server contains the lines ForwardAgent yes ForwardX11 yes ForwardX11Trusted yes and that /etc/ssh/sshd_config on the server contains the line: X11Forwarding yes I then rebooted the server. It came back up no problem. Now, starting X11.app on my Mac I am presented with an Xterm. I connect to my server from this terminal using: $ ssh -X <myhost> and I connect to the server, no problem. At this point I don't know what to do. I have tried $ sudo startx but I get a "no screens found" error. I don't have screens because its a headless cloud server, but I just want to acces it from my Mac through X. What now?

  • Partitions and cdrom are not mounted, and the bars are missing in Ubuntu 12.04

    - by nuit
    Provide my spec and sorry for my poor English first. MB: Gigabyte G31M-S2L (bios ver. F9) CPU: intel E5200 2G RAM HD1: WD 160G with 2 partitions (partition 1:60G, NTFS, win xp; partition 2:100G, NTFS) HD2: WD 320G with 2 partitions (partition 3:220G, NTFS; partition 4:100G, ext4, Ubuntu) Recently, I tried to install Ubuntu 12.04 Beta 2 on my desktop PC (on partition 4). At the beginning, everything looked great including the auto-mounting of partitions 1~3 and the unity (3D). However, after I deleted and re-allocated the partitions on HD2 and re-installed Ubuntu on partition 4, the partitions 1~3 are no longer auto-mounted when I logged in the desktop (and even the inserted cdrom would not be mounted either), and the launch bar and menu bar in unity (3D) are missing. The configurations during these two installations are all the same as default. Are there any possible reasons or solutions for this issue? Thank you in advance!

  • IntelliTrace collector error Some or all identity references could not be translated

    - by Tarun Arora
    If you are running the IntelliTrace stand alone collector to collect the trace against an Application Pool which is running under the identity “.\<username>” then you are likely to run into the following exception, Start-IntelliTraceCollection : Some or all identity references could not be translated. At line:1 char:29 + Start-IntelliTraceCollection <<<<  "FabrikamFiber.Web" C:\IntelliTraceCTP\collection_plan.ASP.NET.trace.xml C:\Intell iTraceLogs     + CategoryInfo          : NotSpecified: (:) [Start-IntelliTraceCollection], IdentityNotMappedException     + FullyQualifiedErrorId : System.Security.Principal.IdentityNotMappedException,Microsoft.VisualStudio.IntelliTrace    .PowerShell.StartIntelliTraceCollectionCommand   Steps to reproduce the issue The application pool “FabrikamFiber.Web” is using the identity “.\Admin”   Workaround Change the identity of the application pool to <MachineName|Domain>\<UserName>. So, in the above work around if I change the identity to “Production\Admin” then the IntelliTrace does not throw an exception. This error has been reported to Microsoft and it is expected that it will be fixed in one of the future releases. Enjoy!

  • License for library developed with commercial program

    - by Overv
    I'm developing a commercial application that largely depends on the functionality of a library that will be developed with it. I'd like to open-source this library, because it offers functionality that is not found elsewhere and can be useful in other applications. However, I will also use it in my own commercial application. I don't want to publish the source of the main application, but it is definitely not a derived work (think of calculator app using GPL licensed library to calculate sine). And if someone else commercially uses the library, I want to require them to publish any changes made. Is the GPL license suitable for this or is LGPL perhaps what I need?

  • Why did this command make my Ubuntu more awesome than before?

    - by the_misfit
    After running Ubuntu for months and liking it, I for the first time wanted to use headphones and was trying to get them to work so I ran the code in step 1 https://help.ubuntu.com/community/SoundTroubleshootingProcedure -- the result was an improvement in performance, resolution, and audio.. a vast improvement. What does that suggest about what was wrong with my settings before if running this improved system performance, graphics, and my audio problem? The command is: sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; sudo usermod -aG `cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami`

  • Can a plug-in access a database server?

    - by Black Panther
    At my work place, we use an external client's web application monitor and respond to support tickets of our clients. the problem with that application is that it does not house a field to enter the actual effort (hours worked on a particular ticket) to be stored in the database. What is needed to write a plug-in for Internet Explorer that would get triggered on a button click on a certain webpage and save some data in an external database? That is, if the support personnel is closing the ticket after resolving it, is it possible to invoke that plugin that asks the personnel to enter the effort spent on that ticket and store it in an external database? We can't modify the web application as it is vendor supplied and not an in-house product.

  • Looking for the better way to combine deep architecture refactoring with feature based development

    - by voroninp
    Problem statement: Given: TFS as Source Control Heavy desktop client application with tons of legacy code with bad or almost absent architecture design. Clients constantly requiring new features with sound quality, fast delivery and constantly complaining on user unfriendly UI. Problem: Application undoubtedly requires deep refactoring. This process inevitably makes application unstable and dedicated stabilization phase is needed. We've tried: Refactoring in master with periodical merges from master (MB) to feature branch (FB). (my mistake) Result: Many unstable branches. What we are advised: Create additional branch for refactoring (RB) periodically synchronizing it with MB via merge from MB to RB. After RB is stabilized we substitute master with RB and create new branch for further refactoring. This is the plan. But here I expect the real hell of merging MB to RB after merging any FB to MB. The main advantage: Stable master most of the time. Are there any better alternatives to the procees?

  • DesktopCouch does not sync

    - by burli
    I have here two computers, both installed with Ubuntu 10.10. The Laptop uses the Netbook Edition. Both are connected, file sync and Tomboy Notes are working. My Desktop syncs databases with Ubuntu One, my Laptop does not. If I delete for example the contacts Database on my Desktop, the database is back a view seconds later. If I delete the same database on my laptop, nothing happens. (I'm using Futon) If I kill beam, delete the config and try to restart with the dbus-send I got an error Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. How can I fix that?

  • How To Remote Control Your Home Computer From Anywhere With VNC

    - by Chris Hoffman
    VNC allows you to remotely access a computer and use its desktop, either over the Internet or from another room in your house. Windows includes a Remote Desktop feature, but it’s only available in Professional editions of Windows. Some people may prefer TeamViewer or another service instead, but VNC allows you to install and manage your own server without using a centralized service. VNC clients and servers are available for all platforms, but we’ll be covering Windows here.

  • Which DB should I use for my newbie program?

    - by knijo
    I'm really new to programming, and I need some advice. I'm currently working on a very simple program to maintain a list of users at a company, as well as their clock in and clock out info. I would like to make this application easy to distribute (on a cd probably), and I'm looking for advice on which database to use for storing my data. My application is implemented using java and swing. A friend recommended MySQL, but I don't want to go installing the db server on every computer the application is installed on. Another friend recommended Access. Any tips would be greatly appreciated

  • Chromium web-app creation doesn't work in 12.10?

    - by speter
    If you create an application of a website in Chromium and choose "desktop", a .desktop file is created. In 12.04, you were able to move it to ~/,local/share/applications/ and then start it from the Dash or the launcher. In my fresh 12.10 installation, this doesn't work anymore. I think the line that is misinterpreted is Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/. If you try to run it from a terminal, you get the following result: 20:32 ~ speter Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/ bash: --app=http://buymeapie.com/: Datei oder Verzeichnis nicht gefunden (English: "File or directory not found"). Can anyone explain or knows a workaround?

  • is it safe to use jQuery and MooTools together?

    - by user1179459
    I just need to know is it safe to use jQuery and MooTools Together in one web framework? I am not trying create application using both of them, but I am in a situation where I need to modify mootool based application framework, so I am used to jquery, I don't want to waste my time learning mootools and I think jquery is better than the mootools in many contexts like number of applications, plugins etc. so questions are is it safe to use mootools and jquery in one framework? will there be cross browser issues? how robust the application will be when using both?

  • Remote GDM login

    - by luri
    Is it possible to remotely (via ssh) make a login to GDM? I'll explain a situation in which I'd need this: I'm on my laptop and connect to my desktop via ssh. I realize there are some updates available. I install them all, but I need to reboot the computer. The problem is that once the desktop has rebooted, there will be no GDM session available, since it's necessary to log in. Can I somehow perform the GDM login remotely from my laptop?

  • How to avoid “The web server process that was being debugged has been terminated by IIS”

    - by ybbest
    Problem: When debugging asp.net by attaching w3wp.exe process, you often will see encounter the following error message, the web server process that was being debugged has been terminated by IIS. Analysis: This caused Internet Information Services (IIS) to assume that the worker process had stopped responding. Therefore, IIS terminated the worker process. Solution: 1. Open IIS manager. 2.Click application Pools>>select the application pool associated with the site>>and click Advanced Settings 3. Click Advanced Settings of the application pool and set the Ping Enabled property from True to False. Now, reattach the process from Visual Studio, you should not get the error message.

  • Reduce boot time between grub menu and login screen

    - by Sudheer
    I use Ubuntu 14.04 LTS version which used to boot fast at beginning but not i loads very slow. I searched for this but can't find suitable answers. so i want to reduce my boot time which is now around 1min 12sec (boot chart) overall but i noticed its taking a longtime after grub menu and before login screen. A Blank screen appears after grub waiting... then login screen appears. I want to know a way to reduce that blank screen time(or if possible remove) and get login screen as fast as possible. I already removed several of my startup applications. Getting desktop after log-in is fast. I don't want to remove unity and install light desktop envinorments like Xfce and Lxde. Here is my boot-chart image Thanks in advance

  • How to set PcManFm as the default file manager?

    - by JarekJ83
    I think Nautilus is so slow, and I'd like to move to PCmanFM, but didn't find any good tips how to do this in Ubuntu 12.10. I have PCmanFM installed already, and I even changed: $ sudo gedit /usr/share/applications/nautilus-folder-handler.desktop [Desktop Entry] Name=Files Comment=Access and organize files Exec=pcmanfm %U Icon=system-file-manager Terminal=false NoDisplay=true Type=Application StartupNotify=true OnlyShowIn=GNOME;Unity; Categories=GNOME;GTK;Utility;Core; MimeType=inode/directory;application/x-gnome-saved-search; X-GNOME-Bugzilla-Bugzilla=GNOME X-GNOME-Bugzilla-Product=nautilus X-GNOME-Bugzilla-Component=general X-GNOME-Bugzilla-Version=3.2.1 X-Ubuntu-Gettext-Domain=nautilus Still slow Nautilus is default one.

  • 12.10 Unity doesn't appear when using Nvidia drivers

    - by Torben Gundtofte-Bruun
    I've just installed 12.10 from scratch. Unity also started okay, but in a poor resolution. I found a setting (I think it was in "software sources") to change the display driver to Nvidia, and then I rebooted. When Ubuntu now starts, it goes to the desktop (I see a file that I saved to the desktop) but there are no other screen elements -- no Unity, no menu bar at the top, no window decoration, nothing. Ctrl-Alt-T and Ctrl-Alt-F2 work as they should, but it's kinda limiting... How can I restore the default driver? I guess I need a way to open those "software sources" settings again - or anything else that could fix it! I hope I don't have to type all this by hand. How can I install a proper Nvidia driver so that I can get up to 1280x1024? My old tricks don't seem to work, but perhaps they might if I solve #1...

  • Welcome to our Friday tips series!

    - by Chris Kawalek
    Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog. Today's tip is on Storage and Oracle Virtual Desktop Infrastructure: Question: I run Oracle Virtual Desktop 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache?  Answer by John Renko, Consulting Developer, Oracle: Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system: set zfs:zfs_arc_min = 5368709120 set zfs:zfs_arc_max = 5368709120 The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

  • script shortcut to open two files in gedit as sudo

    - by Sam
    I want to double click a file on my desktop, and have two files be opened in gedit as sudo. Whenever I'm making a new website, I need to open /etc/hosts /etc/apache2/sites-enabled/000-default.conf as sudo. At the moment this means opening the terminal, runing sudo gedit then opening each file manually. I want to streamline this part of my workflow. On windows I had wrote a little bash script which worked nicely. How can I do the same in ubuntu? So far in my searches I've come across ways of adding a shortcut to the file browser, and similar things, but not exactly what I want. I have tried creating a desktop launcher, but can't see how to make it run as sudo.
