Installing GnomeTweakTool and Dconf Editor

To install GnomeTweakTool and Dconf Editor on Fedora 17 or 18 using Gnome-packagegit (a GUI):

  • Press the Windows key or Alt+F1.
  • Type "Software" and press Enter; this opens the GUI for adding and removing software.
  • Search "gnome-tweak-tool"; in the search results, check the checkbox for "gnome-tweak-tool" and press the button "Apply changes"; you will probably need to enter an administrator password to allow the installation.
  • Repeat the previous step for "dconf-editor".

To install GnomeTweakTool and Dconf Editor using the command line:

  • Open a terminal.
  • Log in in as root by typing "su --login" and provide your root password when you are prompted for it.
  • Run "yum install gnome-tweak-tool" and confirm that you want to install this package when you are prompted for it.
  • Run "yum install dconf-editor" and confirm that you want to install this package when you are prompted for it.
  • Type "exit" to log off as root.
  • You can now type "gnome-tweak-tool" and "dconf-editor" on the command line to run these tools.
  • You can also run these tools by pressing ALT + F1 (or by pressing the Windows key) and then entering "dconf" or "gnome-tweak" in the Run window.

(See other examples of using yum.)

Sound Card Issues

If Orca remains silent, this may be due to a more general sound issue. If your hardware does not use HDMI, the following steps may work. (Sound problems related to HDMI for Fedora 17 have been discussed on FedoraForum, esp. for NVDIA GeForce cards.)

  • First, look for the sound device:
    • open a terminal (press Alt + F1, type "terminal" into the search box and press Enter),
    • in the terminal, type lspci and look for the sound device in the output,
    • make a note of the number before the sound device, e.g. the first numbers in the line 00:05.0 Multimedia audio controller: Intel Corporation 82801AA AC'97 Audio Controller (rev 01)</kdb>.
  • Go to the sound settings (e.g. the speaker icon at the top of the screen in Fedora 18) and check whether the device you find in the previous step is listed there.
  • If the sound device is not listed, run alsamixer in the terminal.
    • Press F6 to select the sound card (in the list that appears after pressing F6, use the up and down arrows to move through the list, and the Enter key to confirm your choice).
    • Go back to the sound settings and test the speakers.
  • If there is still no sound, go to the terminal, run and lspci -n | grep @@:@@.@; "@@:@@.@" stands for the numbers in the first field from the previous listing. (To continue from the previous example: lspci -n | grep 00:05.0.) This gives the device's product ID.
  • Try running alsactl init in the terminal. (See Red Hat Bugzilla – Bug 896164.)
    • Go back to the sound settings and test the speakers.

Note: Running alsactl init only solved the issue for the current session; you would need to run this again next time you log in to Fedora. A more permanent solution is described below.


  • In the terminal, go to the directory /etc/xdg/autostart.
  • Create an empty file named alsactl-init.desktop by typing sudo touch alsactl-init.desktop. (You'll need sudo because otherwise you don't have permission to create a file in

that location.) Enter your password when requested.

  • Open the file in gedit by typing sudo gedit alsactl-init.desktop. You need to use sudo and your password for the same reasons as in the previous step.
  • Add the following lines and save the file:
[Desktop Entry]
Name=ALSA initialisation
Comment=ALSA custom initialisation
Exec=alsactl init
  • Sound should be working the next time you log in.
