If you are using Fedora 8 with KDE you may have noticed an interesting bug. Once you open some Gnome apps(for example, Exile, all the fonts in the KDE applications becomes one size smaller.

If this happens, the only way to fix it is to restart the X server - or so I thought. At first, I thought it was the issue of just one application - namely RhythmBox.

But I just found that there is a simple fix for this problem…

• Run the command ‘gnome-appearance-properties’
• Go to the ‘Fonts’ Tab
• Click on the ‘Details’ Button at the bottom
• Change the Resolution to 96 Dots per Inch(DPI)

That should solve your problem.

This issue appears only if your screen resolution is bigger than normal - mine is 1440×900.

Today I upgraded my system from Fedora 7 to Fedora 8. The installation process went very smoothly. But once the installation was done, I started the long process of configuring it. That’s when I ran into the sound issue in Fedora 8 - and based on the forum posts, so did many others.

Basically, you get this error at KDE startup…

Sound Error Informational Message:
Error while initializing the sound driver:
device: default can't be opened for playback (Permission denied)
The sound server will continue, using the null output device

You will not be able to play any sound - amarok will crash if you try to play anything. But if you run system-config-soundcard(or System -> Administration -> Soundcard Detection), you will be able to hear the test sound. That is because you are running it as root.

Solution 1 - Console-Kit Service

Did you turn of Console-Kit and avahi-daemon startup services using system-config-services? If so, go back and re-enable them.

• Run system-config-services(or System -> Administration -> Services)
• Find Console-Kit and enable it
• Find avahi-daemon, enable it
• Restart the system and see if that fixed the problem.

This worked for me - so I did not try any of the following solutions.

Solution 2 - alsa-plugin

If the first solution did not solve the problem, try removing the pulseaudio plugin for alsa by running this command.

yum remove alsa-plugins-pulseaudio

Solution 3 - Permissions

If neither of the above work, open /etc/security/console.perms.d/50-default-perms and add this line to the top…

<sound>=/dev/dsp* /dev/snd/*

And at the end, add this line…

<console> 0666 <sound> 0600 root
