Fedora :: Using 'su' For GUI Applications?
Nov 11, 2009
I'm doing app development, and the app interfaces with some I/O devices which requires root permission. I'm unable to become root through terminal and run these programs (ie, go into terminal and type in 'su'). I get this error several times in succession when I attempt to run *any* GUI app (even gedit):
GConf Error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See [URL] for information. (Details - 1: Failed to get connection to session: 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.)
I read somewhere else the solution was to type the following into terminal:
xhost +local:
But it doesn't do anything (same error after reboot).
Also, can I just make my user have admin priveledges? I realize there are reasons why this is not normal howeverI'm the only one who uses the system, and it's only for development. I don't like having to log in as root through the terminal every time I want to debug my program.

I feel shy asking this question but, 90% of the applications I install in Ubuntu (last release), do not show up later on in the applications menu, so I cant run them. I know it seems silly, but I can't find the way to handle this inconvenience. Is there a place (like Start> All programs in Windows), were I could find and run all the programs I install?

I was wondering if there was any way to remove icons from the installed applications menu?I recently attempted to install GOG.com's Zork Anthology using Wine and when I de-installed, the icons for those files were still listed in installed applications. Is there anyway to delete them manually?

I'm setting up a large number of virtual machines, each with a basic set of about 30 applications. Obviously, I don't want to do everything manually so I'm looking for ways to automate this process. Multiple distributions (Ubuntu, Red Hat Ent., FreeBSD, CentOS, etc.) will be used, meaning I will have a few Ubuntu installs with the basic set of 30 applications, and multiple Red Hat installs with the same set, etc. So, I'm looking for advice on automating as much of this as I can, even if it means a new form of automation for each distro.

Is there a programmatic way to get the list of all installed applications on Linux.
Also, how can we get the application activities in Linux OS like running applications name, time of day when they started, duration till the applications were running on system, application version etc.
Is there a way to do this in C/C++.
I am building an app that runs like a daemon and fetches the applications status and sends it to the network admin for him to monitor the application usage pattern on the user computers in the network.

How would I use 32-bit applications on 64-bit Fedora 12? I know in Ubuntu you just install IA-32, how would I do that on 64 bit Fedora 12? I'm putting this on the forums from my mac because I am deciding whether to install fedora 12 32 or 64 bit on my macbook, dual boot.

I installed Fedora 11 last night and found that it installs a lot of applications and utilities that i dont need and will never use. I tried to customise the installation before installing but there is too many of them that i just gave up.
All i need is the Apache Webserver and the mysql database. is there an easier way to installl a quick Fedora installation with just the webserver and the database and nothing else?

My internet's been kinda slow lately, and I can see the "activity" light on my router blinking like crazy but I'm not doing anything related to internet.
Is there a way to find out which applications are using the internet?

I am having a problem when I try to run certain programs as root via the terminal (this problem mainly occurs when I try to run a GUI application).
Before installing F14, running gedit as root was never a problem and I always did it when modifying system files. But in F14 it seems to be a problem. Here's what I run...
For example, I execute:
Code:
And get this output:
Code:
The same problem occurs when running other programs:
The output of running totem as root is:

The output of running firefox as root is:

I just installed fedora 15 and I can't seem to find my way around Gnome 3.0.1. In fedora 14 when I connected an external hard drive it used to automount itself. I can't find it in fedora 15 though.
How do I set startup applications in fedora 15? In fedora 14 I used to have this wizard to which I could add an application that I would want to run on startup.

I have what seems to be far to many KDE programs running on my Gnome desktop is this normal?
I thought there would be gnome equivalents.
I'll list them:
Is this normal for a Gnome Desktop Fedora installation and if so which are completely arbitrary and can be removed safely?
Also is xorg supposed to use 8-20% of the CPU when all that is running is the system monitor? The system monitor application also uses 20-70% of the CPU when it is running by itself also. (Intel Pentium 4, 3.2ghz)
I didn't choose any KDE desktop Applications Intentionally

If I am correct there is an official list(probably by Fedora itself) of packages/software included in each Fedora version, but I can't find it. I also have a couple of queries below.
1. There are always new applications, packages, games etc. being released for Fedora by open source developers and companies. Is there a good website where I can get a list of all these new packages etc, if possible an official one? I visit some sites such as Linux.com, but based on your own experience, I think you can guide me better.
2. In order to know which packages are installed on the Fedora machine one can type the following command, is that right?
Code:
rpm -qa
And this one gives the exact number of installed packages.
Code:
rpm -qa | wc -l

I installed Fedora 13 and use the Gnome desktop. I want to keep my installation as clean as possible and have heard some contrary advice about installing both Gnome and KDE desktops, so I want to stay with just Gnome. In the past I have mixed both and feel that resulted in tons of packages that I probably didn't need and tons of updates all the time. However, some applications seem to be KDE applications and installing them requires installation of many KDE packages. This is a source of confusion for me:
Is there a distinction between Gnome applications and KDE applications? If so, how do you tell the difference? Should one NOT install KDE applications if you are using the Gnome desktop and not interested in installing KDE desktop? Is there a best practice on how to approach which software to install so that you do not create a mix and match mess?

I've been using Fedora 11 x86_64 for over a year and am about to upgrade to Fedora 13 using a genuine Fedora installation CD that I got last summer at OSCON. I've made a full system backup, but before I take the plunge I want to get a list of all installed applications. I have tons of special applications installed, many of which took tweaks to get running. Just in case something breaks so badly that I have to reinstall I want to be sure I can put everything back, even if it takes me several days work.I know I have read about utilities that will generate a list of installed apps, but I can't find any.

I am using Fedora 13 64bit on Dell Vostro full 4GB RAM system with default Gnome GUI.
This is very annoying problem that I don't how to fix except by rebooting the whole PC.
When I have too many applications running ( like browser windows), the system start acting sluggish. The fist symptoms appear in Eclipse IDE which becomes so terrible it just becomes frozen for sometime one whole minute after I try to edit something in the editor. Then Firefox seems like it has crashed. Google Chrome becomes very unresponsive as well. All GUI applications including File manager becomes unresponsive.
When I check System Monitor, the CPU is still around 20% and memory is at 80% but the system seems getting fried up. This progressively becomes worse until I soft reboot it or if I dont do it evetually the whole system is fried, no response to any keyboard key or mouse and I have to hit the hardware turn off button.
I regularly yum update the system but this makes no difference.
Please don't tell not to run too many applications because I need those for my work. I thought Linux is well designed Operating System but I am very disappointed so far.

I have the xfce 4.6 desktop installed with Fedora 14 x64. First, I started having some problems, not sure if they are connected: the menu button on the panel somehow moved from the bottom left corner by itself, the window manager won't open, all windows (browser, programs, etc.) are cut off so that the strip with the minimize/maximize symbols up in the top-right corner is not visible, all windows open in top left-hand corner of screen and can't be moved, workspaces disappeared form the panel, unable to switch windows (have to close the window in focus to access another), typing in some applications (terminal, text editor) does nothing sometimes but works when I reopen them, etc.
.. After this had been going on for a while (few hours), I was changing the panel icons, and the bug report icon suddenly showed up and said that package gnome-1:0.8.1-10.git20100831.fc14 of the gnome network manager (xfce doesn't have it's own network manager?!) and the ibus keyboard layout switcher plugin had crashed. These don't seem to have anything to do with the troubles I'm having; the internet works fine. I have copies of the bug reports but I'm not sure if I should post them since the bug reporting tool warned me that they may contain sensitive information.

So...without editing ~/.config/autostart (which I can't find in F15...) How does someone set a startup application?I notice Gnome 3 does not have the "startup programs" option available any longer.. So, I went searching with the hopes of running it with trusty terminal:
Code:
#yum whatprovides gnome-session-properties
You can use "*/gnome-session-properties" and/or "*/bin/gnome-session-properties"

It's a newbie question that has probably already been answered hundreds of times, but Google didn't help me.
How can I install an application I've downloaded from the internet?I know I can easily install software with the terminal (apt-get, yum etc.) and that there is also a package manager. But still I'd like to know how to install an application I've downloaded with the browser. I've downloaded Thunderbird from this link URL...and after unpacking, I have a folder called 'thunderbird'. Now, what do I have to do to install the application?
I'm not actually concerned with installing Thunderbird anymore because when I typed 'thunderbird' in the terminal, it told me that it isn't installed and if it should be installed. I replied 'y' and some minutes later (slow internet connection...) it was installed and ready to use..

I have the problem that Fedora doesn't save my default applications.When I change it, it does work for some time, but when I reboot it's all gone. So every time I open Chrome I have to select "Make default browser" (very annoying). It doesn't save the default settings for specific extensions neither. For example when I open a .exe file it always open with Archive Manager now while I have selected Wine as default program for that.
