Task Manager for Fedora

Task Manager Fedora: We are used to task manager in Windows operating system. It is very handy to kill unresponsive programs in our system. Likewise it will be good if we have one such tool in Fedora. Fortunately, Fedora has one tool by default. The name of the tool is System Monitor. It can be found in Applications shell. Let me explain how to use the System Monitor to kill or end an unresponsive application.


Steps for using System Monitor:
1. Open System Monitor from Applications.
2. It will open a three tabbed window that contains Processes, Resources, File System.
3. Don't bother about Resources and File System tab as our target is to kill unresponsive program.
4. Say if Google Chrome browser is the unresponsive program, then click on the chrome listed in processes and click on 'End Process' button that you find below.
5. Like this you can kill any program that are not responding.

You can also try using Htop.

VLC media player not running as Root user in Fedora 19?

In Fedora 19, VLC media player won't run as root user. If a user try to run VLC media player in Fedora 19 as root user, it shows following error message.

Issue
# vlc
VLC is not supposed to be run as root. Sorry.
If you need to use real-time priorities and/or privileged TCP ports you can use vlc-wrapper (make sure it is Set-UID root and cannot be run by non-trusted users first).

Solution
It can be made to run as Root user by simple modification in VLC config file.
Step 1: Open Files application.
Step 2: After Files application gets open, in the side pane there will be 'Computer', click on it.
Step 3: There open bin -> usr -> vlc.
Step 4: In vlc file find geteuid and change it to getppid.


Is it safe to modify the file?
VLC by default won't open in root user. The reason behind it is security. As it is a third-party application, it is possible to download it with some malcious code. So it is not recommended to run VLC media player as root user. Linux recommends user to use normal account for everyday activity. Root user should be used only for some modifications in the system. If you are not worried about your security then go ahead and change the file.
