This is a general newbie question about using a GUI on Linux: If I got it right, all graphical applications in Linux ultimately call the X server to display output on the screen, even on the local host. Isn't there a performance penalty to go through a local server application to write output instead of just writing to the video card? Can Linux GUI apps run without an X server?
View 9 Repliesi m experiencing some problems connecting via ssh two ubuntu workstation: a ssh client and a ssh server The goal of that is to run from local client computer some X applications on the remote server machine
i have configured both client and server for X11forwarding (i think) properly Infact when i launch xeyes on the client i see the X app running
the problem is for all other X apps. For example when i run xclock, nothing happens on the local PC the prompt continues blinking without any reponse, no windows opens and the strangest thing, the shell is stucked. No possible to interrupt with [CTRL]+c the onyl thing to do is close the shell window
Starting in verbose mode (debug), X11 seems works correct , it says x11 confirm as last message .
My desktop is running 'buntu 9.10 and I have recently aquired a couple of half decent servers running Windows server 2003. I have a few windows app's that I use regularly for work that I have had limited success in running with wine or in vm's. I stumbled upon a how to to call apps in a vm to run seamlessly on the host desktop and did some playing and have succeeded in calling app's on my servers from my 'buntu desktop, the command I have set in my launcher for one of them (DIALux)
My question is, can I change the default application/file association in 'buntu with a custom command so I can double click on a file and have it open in one of these remote app's??If I can, what is the correct custom command to be using as using the above doesn't work at all, it just tries to open the file with rdesktop not the remote app.
Some minimized apps no longer appear in the top menu and by that are no longer accessible.For example firefox with the minimize addon or Jungel Disk backup service.How can I reach apps that minimized them self and are not shown in the top menu?

I have headless debian as a server which i use over tightvnc server running on it. Vnc works fine but I can't for example run sudo mousepad or any other gui app from terminal, it says something about not having the rights to open it as root. I understand this has something to do with security, but my computers are behind nat so the vnc server can only be connected inside my lan so i don't mind.
View 7 Replies View RelatedBackground: I need some help regarding install X server/apps on a headless(ie. no monitor, no graphic device) server. The server is in fact a virtual one by Amazon EC2. So there's no monitor nor any graphics hardware. Fedora server (6, i believe) is pre-packaged. The problem is that I want to be running a server app with a GUI. The app won't start without the GUI (and I probably need to tweak a few things through its GUI too).
I plan on setting up very very bare minimal X on the server and then uses NX for remote access. Can somebody shed some light here?
Simply put, my questions are:
1) What would be the minimal list of package i need to install?
2) Where can I find docs about installing and setting up NX? I could only find very fragmented/outdated docs about it.
I think this is a really simple question...forgive me. My installation of Ubuntu server went fine, the box runs great. But I forgot to select "LAMP" server for web/php/mysql etc services. I could re-run the whole thing, but isn't there a shell command to kick me back into the script so I can just add the LAMP stuff?
View 2 Replies View RelatedI have an OpenSuse 11.2 system that is running 2 BBS systems independently, both of which are capable of receiving smtp mail on prot 25. What I would like to do is set up Postfix on the OpenSuse OS to receive all mail for both those domains and then send the relevant mail to the correct BBS. I would therefore have Postfix listening on Port 25 External and the 2 BBS applications listening on different ports on the localhost address. At least that is the plan.
how to do this. I want to do it and still make sure Postfix is secure and not accidentally open up any nasty relay holes etc etc.
Ok I am finally fed up enough with Microsoft to actually consider making my primary computer system a 100% Linux system... I build a really nice system about a year ago and got Windows 7 64 bit edition (all software is legal and legit) and my computer frequently freezes at random times... I'm pretty sure its not the ram or the motherboard and I run two hard drives with raid0 striping... I have used various Windows OS's on here and they all randomly freeze up during operation.. sometimes during heavy gaming and sometimes right when my system starts up... I dont think its a heat issue since I have a huge and efficient $75 heatsink/fan combo designed specifically for my cpu...
If I make this move, it will cost me a lot since I use a lot of Music and applications such as Ableton Live and Reason, and 3D software like Cinema 4D and zBrush.... Photoshop CS4... and games like Call of Duty MW2....
Will I still be able to use all my apps? I have heard of Wine but have never used it and I dont know how much you can do with Windows apps on Linux these days...
My system: i7 Quad Core/6GB ram/EVGA X58 mobo/GeForce9800GTX...
What I am looking for here is assurance that I will be able to run most of my major applications on Linux with out losing much system efficiency.
None of the apps will work on DSL. Example Firefox or notepad will not open. FF says input/output error. it is a compaq presario laptop with win xp sp3 in case that is important. I am not sure if the windows reference is important at all?

OS: Fedora 14 i386It's used as a ""normal desktop laptop""."USER A" - it's the mainly used user, i log in with GDM with it, etc.Goal: I need a little more security - separate a few apps!How: run 3 applications ( Transmission, Google Chrome, Wine ) with other users ( so not with "USER A" ). But when i'm logged in ( in GUI ) with "USER A", i need icons on he's the Desktop. E.g.: just one click ( without asking for password!! ) and Google Chrome starts with another user.How exactly can i do this? - How can i "grant" "USER A" with permissions ( securely ) so that it doesn't needs a password, when running applications with "USER B", "USER C", etc.?

I have just got an Nvidia GT240 card and have for the first time set up dual monitors (An LCD @ 1024x768 and a projector @ 1152x864) I have them set up as twinview so I can drap/drop between the two and run compiz across the two. My problem is in running some games (Hedgewars, Powermanga, I have no tomatoes) These games run full screen and currenlty span the two monitors which is not workable as they are not side by side and run different resolutions. How can I tweak these apps to run on only one monitor without altering the xorg.conf and losing the functions mentioned above? I have found a resolution setting in Hedgewars but it only give one option and does not allow me to overtype it.
View 4 Replies View RelatedI want to write something that will run apps in succession.For example, you'd click on the app icon,and it would start up one application, have questions alert the user to add a file to do something in that program, run that program & finish. Then open up another program to take that file and prompt the user to do something else with it, and so on.Basically I have a friend who needs an auto, completely easy interface to accomplish certain tasks that require multiple application steps to perform.
