Setting of a password does sound like a Gnome/KDE thing. I can't
comment on that since its been at least 7 or 8 years since I swore off
the mega-managers and use Fluxbox to select which xterm to use ;-)

When I'm in Xorg, I just issue the commands from an xterm. Xset should
keep track of your settings for you without having to add it to

I'm of the opinion that these drivers should work out-of-the-box for
a given card with the configuration file generated thru Xorg. If
they don't then new users will have a less than happy experience
when they install FreeBSD. Understandably, special features of a
card may require additional hand configurations.
What the patch does is to revert to the mga-1.4.7 with some bug fixes
making it 1.4.7,1 . If you had no problems with the previous 1.4.7
driver then it should work fine. Keep in mind, its still a PR and
subject to further modification/approaches.
If you're comfortable with doing local patches and being able to deal
with them during subsequent port updates then it might be worth
If you want to read further you could look at last week's archive
and this weeks current mailings:
Look for postings regarding the 'mga' driver.

Xorg is another third-party software like other ports and can have
a PR filed for a problem. Of course, its preferable that changes
go upstream so it minimizes patches for FreeBSD since this adds
extra work for the maintainers.
