Using X11 applications without having xorg-server installed.

Hello,
I have 2 computers in my network: one is a powerful 8 CPU SPARC, the second is quite old and has 4 slow CPUs. I'd like to run graphical applications on this slow server (logging into it via ssh, server doesn't have either vga nor monitor, it's usable only via console login and ssh), but I would like this powerful computer to be a X11 server - it should work with all those graphical programs that I will run on slow computer. Is it possible (if yes, I would be glad if you tell me how) to remove X11 server software from slow computer (leaving there only client apps, like mozilla, xclock, etc.) and configure it in this way, that this powerful computer will handle all X11 requests?
Thanks for help,
Konrad

Just don't start an X server on the slow one.
Then you could either ssh into the machine and run programs with your display explicitly set to the other machine.
(Only necessary if you're not using SSH X forwarding)
fast_machine$ xhost slow_machine
slow_machine being added to access control list
fast_machine$ ssh slow_machine
slow_machine$ echo $DISPLAY
(If set, run your programs. If not set, set it explicitly)
slow_machine$ export DISPLAY=fast_machine:0
slow_machine$ xterm

  • Running Adobe AIR applications without having Adobe AIR installed

    Is running Adobe AIR applications without having Adobe AIR
    installed possible?
    Why wouldn`t it be?
    And if not, when will it be possible?
    Thank you.

    There's no technical way this could be possible. It's like a
    .swf playing without the Flash Player installed, or a Java applet
    without the Java Virtual Machine. Or even like a Windows
    application running without Windows. :)
    There are, however, 3rd party wrappers out there to turn AIR
    apps into native OS apps (basically it wraps the AIR Runtime inside
    a native OS executable, like .exe). One that I can name off the top
    of my head is the Shu wrapper. This is like the old school Flash
    projectors, like Zinc and mProjector. The user doesn't have to
    install anything to run native executables.
    I would be surprised if Adobe has any plans to make an
    executable wrapper for AIR, but I don't know anything. I would like
    to see .air files be able to run in the AIR Runtime without having
    to actually install the .air package, though.

  • How to run java application without having java environment in  a machine

    can i run java application without having java environment(JVM) in a machine.I mean i dont have installed j2se or jdk in my machine.And i have an j2ee application running on another host which is built in swings.I want to access that application in my machine
    can any one help regarding my problem

    If you only need to access the program from one machine and you are running a Unix-like operating system (e.g., Linux, Solaris), you can use the remote display capabilities of X11. In this case you have to choose the host where the app will be displayed when you start it:
    $ DISPLAY=<hostname>:0.0
    $ export DISPLAY
    $ java ...
    If you want to be able to display it on both machines at the same time, or if you are using windows, then try something like VNC (http;//www.realvnc.com). Or if you are running windows and your version supports it, you can use windows remote desktop.

  • HT4995 Internationally using Location Services without having data charges.  What settings should use on my iPhone 5?

    I'm traveling to Europe and I want to use Location Services without having data charges.  What settings should use on my iPhone 5?  I want to be able to use Trip Advisor City Guides Application to tour around cities for free.  I have a Verizon International Plan for my trip, but it is still pricey.  I would like to keep my iPhone cell services on for incoming calls, but I want to prevent international data charges.  Thanks for your help!

    You don't "choose" to use th 3g network.
    If you have paid for it in your plan and 3g coverage is available, your phone will automatically use it when necessary.
    3g provides faster internet speeds than 2g, so you can watch video or download stuff faster. Wifi is normally faster than 3g.
    Your iphone gps is "assisted", meaning it uses network data to calculate your position.
    Also, you would still need the network to download maps, directions etc as they are not on your device.

    Apple TV requires an HDTV. It is a media streamer and all content would be available on your Mac so there would be no reason to connect it anyway.

  • Using X11 application as default for file type?

    Hello,
    I wanted to know if it's possible to set an X11 application as default application to open a certain file type.
    I tried the "open with" option on a file type, but the X11 application I wanted to associate to was unavailable (impossible to select) in the file explorer window.
    Thanks.

    Unix executables are not usually "visible." "Standard" OS X applications use the ".app" extension, but Unix executables do not. I suspect that's why you are having the problem. Making the association through OS X may not be possible.

  • Using Equalizer presets without having to switch on and off

    Hi,
    I have assigned equalizer presets (eg. Equalizer preset = Dance) to a minority of songs in iTunes on my Mac. Most songs have no preset, so the setting is blank (Equalizer preset = None).
    The problem is that I can only get these settings to work by manually switching the EQ 'on' and 'off' by checking and unchecking the 'on' button in the Equalizer window.
    Can I combine presets and no presets in one playlist without having to manually switch the EQ on and off? If so, please tell me how. Thanks!
    iMac G5/17"   Mac OS X (10.3.9)  

    iTunes will change the EQ to a setting but not back to nothing.
    If your listening to a dance track with the EQ preset on Dance then thats fine. But continue on too listen to a rock track where the EQ preset is none and iTunes will continue to use the Dance EQ. The only way i can think of to get around this problem is to set EQ presets for all songs. If you have a large library its easiest to do this by browsing by genre and changing whole genres at once.
    There is no software i know of that helps prevent your EQ problem though sorry

  • How can i get user to use my application without logging on as a developer?

    Hi
    Can anyone tell me or point me in the direction of information regarding allowing users to be pointed straight to an application on apex. Curently i log in via the apex.oracle.com home page use my database name then my username and password. But that only gets me in i want to allow user to be able to view and use the applications. How can i do this? Or is this indeeded possible i would assume that it is.
    thanks
    Dan Stead

    Dan,
    Another possibility is that if you host it yourself, or go with one of the production hosting companies then they can help you to configure it so that you can point a DNS name (e.g. www.yourapp.com) to point to your application, so that is all your users would need to enter into their browsers.
    You can find a list of hosting providers here -

    (in the interests of disclosure, I run one of those companies on the list)

  • Is it possible to have a user interface in a stand alone application without having LV

    Hi!
    I want to know if it's possible to build a stand-alone application in order to avoid purchasing LV and at the same time having a user interface to display data?
    I really want to know what are the advantages of the stand-alone applications and what are their limits of use?
    Thank u

    If you have the application builder (included in LabVIEW professional and above) you can make a LabVIEW application that can be distributed and run on machines that don't have LabVIEW installed. If you only have LabVIEW full, you can purchase it seperately.
    The target machine requires the LabVIEW runtime, which is freely downloadable from NI, or can be included with the installer of your application.
    Please have a look at the datasheet: http://www.ni.com/pdf/products/us/4msw55.pdf
    If still have more specific questions not mentioned in the above link, please ask.

  • Itunes didn't update install or uninstall is there a way to ininstall itunes without having to re-install windows?

    Will not uninstall, install or update now what windows 7

    I've just (finally) managed to fix this problem today. I checked the Apple Support forums, and it seems a lot of people are having the same problem.
    I rang the Apple Support line, and the very helpful man (thanks Alan!) talked me through it stage by stage. If you go to the following page on the internet:http://support.apple.com/kb/TS5376   it takes you through the process. WARNING - it takes a little time! The main purpose of this is to remove any trace of the old version of iTunes from your computer...
    Basically, the first thing you have to do is go to your Program Files and double click on your iTunes folder. There'll be a number of files with the suffix .dll - you need to move all the .dll files from that folder to your desktop - you can simply click and drag them on the desktop..
    Next, uninstall iTunes - go to Control Panel / Add/Rempve Programs and when the list comes up remove iTunes. This will take a few minutes... Then reboot your computer.
    Next, go back to Control Panel / Add Remove and Remove - IN THIS ORDER -
    Apple Software Update
    Apple Mobile Device Support
    Bonjour
    Apple Application Support
    Reboot again!
    Next, check in your Program Files that the iTunes folder is completely gone - if it has, great: if it hasn't, right-click on the folder and press Shift and Delete - it will say "Are you sure you want to completely remove the folder "iTunes"? Click on "Yes".
    Reboot!
    Then go to the iTunes download page and voila! It should download iTunes without any problems... well it did for me.... Good luck!

  • Linking between ApEx applications without having to re-login

    Hi all,
    Application Express 2.1.0.00.39
    Oracle Database 10g Express Edition Release 10.2.0.1.0 - Product
    This is talked about all over the forums but I'm fairly new to this and can't seem to get it to work. e.g.
    Re: handling of authentication between applications
    shared session
    So I have three apps 103, 101, 102. App 103 has a tree which contains links to apps 101, 102. When I click these links however, I am required to log into each of the applications separately.
    Other posts say to ensure I'm using the same cookie and to add "&SESSION" to my link URLs.
    So here's my tree query in app 103 which generates the links:
    select "ID" id,
    "PID" pid,
    "NAME" name,
    'http://127.0.0.1:8080/apex/f?p=' || id || ':1' link,
    null a1,
    null a2
    from "#OWNER#"."ORHA_APP_HRCHY"
    When I add "&SESSION" to the end of the query I get:
    Bad Request
    The HTTP client sent a request that this server could not understand.
    What is the correct URL?
    I believe I'm sharing a cookie because all three apps have an autogenerated login process:
    wwv_flow_custom_auth_std.login(
    P_UNAME => :P101_USERNAME,
    P_PASSWORD => :P101_PASSWORD,
    P_SESSION_ID => v('APP_SESSION'),
    P_FLOW_PAGE => :APP_ID||':1'
    Or maybe that's wrong?
    I'm using database account authentication. Maybe that's the problem?
    Thanks,
    Craig

    Well it appears for one thing I missed the "."
    Re: Use SESSION variable in URL from HTML region
    Changing my tree query to the following seems to generate the appropriate url:

    'http://127.0.0.1:8080/apex/f?p=' || id || ':1:&SESSION.' link,

  • Using calculator application without numeric keypad?

    Hello,
    I have a little but very frustrating problem. I was bought a new MacBook in the last week to replace my old PowerBook 12". Everything is fine, I like the new machine but the numeric keypad is missing. This isn't a catastrophic problem, but I can't use the calculator application only using the keyboard! Why? In the calculator application doesn't support the multiplying key (AltShift,) if you are using Hungarian keyboard layout. Any other function is working fine (add, sub, div). With the numeric keypad we can handle this problem, but without it: no!
    So anyone can help me how I can solve this problem?
    Best regards,
    Peter

    I'm not used to Hungarian keyboards but am I right that the multiplying key is the one with the 'Ú' (just googled it)?
    Then you should try to access it with ALT+Ú ... NO shift.
    Maybe this could work. Just give it a try =)
    Edit:
    Hm or it could be the '-' key...
    But I found something interesting on the net:
    http://blog.felho.hu/hungarian-unicode-qwerty-keyboard-layout.html
    It's an apple keyboard there =)

  • Using 2 application on 1 terminal server

    Hi ,
    I have 2 application running on my terminal server . and in terminal server you can only run 1 application on login , how to setup the terminal sever to boot 2 application and the user choose with one he want to use .
    is it the best way to create a group policy and stop everything and on the desktop and just keep the 2 icons .
    if there is any solution please let me know

    Hi,
    I think a remote application being published is the best way to tackle this. That way you can publish the application to a web page, or to the users start menu, and they can select it, it will then launch only that application. The user can run multiple
    applications simultaneously this way too.
