Boot Flickering Issue

During a non-graphic boot of Fedora or a RedHat Enterprise-based distribution, the screen will blink and click during the boot. It sounds as if the display mode is changing. A lot of effort has gone into providing an X-based boot progress indicator, in part to get around this issue. However, for a non-desktop server setup, an X-server startup isn't required.

I'm not sure what the cause of this issue is, but I found one message that inidicated that it might be related to the 8-bit fonts. I set the /etc/sysconfig/i18n file to use only 7-bit characters as shown in Figure 1, “7-Bit Configuration In i18n File”.

LANG="en_US"
SYSFONT="lat0-sun16"	
      

The above settings seem to have worked around the flickering.
