The problem is even more annoying when xvidtune is used to adjust the
screen size and centering parameters on a monitor which isn't auto-adjust
and the modeline is ignored at subsequent bootups. See
This bug report has been ignored for 1.5 years and will be closed unless
someone running FC7 or FC8 takes action. (I'm still on FC6.) Per the
last comment posted 2008/04/03 for this bug:
"Based on the date this bug was created, it appears to have been reported
against rawhide during the development of a Fedora release that is no
longer maintained. In order to refocus our efforts as a project we are
flagging all of the open bugs for releases which are no longer
maintained. If this bug remains in NEEDINFO thirty (30) days from now,
we will automatically close it.
If you can reproduce this bug in a maintained Fedora version (7, 8, or
rawhide), please change this bug to the respective version and change
the status to ASSIGNED. (If you're unable to change the bug's version
or status, add a comment to the bug and someone will change it for you.)
