Is this possible?

There is a bug in the release of XFree 4.3.0, where underlines don't show up for TrueType fonts, in Mozilla browsers. There was a bug report filed, click here to read it. The problem was fixed, and a code patch attached to the bug report.

Now, I downloaded the entire source for XFree 4.3.0, but it seems kinda excessive to rebuild X completely when all that is changing is one source code file, xc/lib/font/FreeType/ftfuncs.c. Is there a way to just rebuild the files affected by this source code file? If so, I could do that and just replace these files manually.

Well Locura, there's a way to everything... but in this case, if you're not a programmer or someone who can understand any given C/C++ structure just by looking at the code, then there's not much you can do except recompile everything.

Well I'm pretty good at coding, I just don't wanna spend all that time looking through and building manually. Just was hoping there was some command argument for make that I could use to do that.

So, what directories/config files should I back up before I install the new version of XFree?

Well...

Some of those are symlinks to X11R6 on my system, should be similar to yours so please be careful when tarring.

I compiled the other day, but I had so much to do with work that I didn't have time to install until this afternoon.

I did a ton of searching, and came up with the following directories, which I tarred and then deleted:

/var/X11R6
/etc/X11
/usr/X11R6

Then I installed, and voila! Works like a charm, though I am a little overwhelmed by all the underlines that I haven't been seeing due to the aforementioned bug that caused me to recompile, haha. The only thing that I don't seem to have now, is xscreensaver. I'm guessing it was in /usr/X11R6/bin or something.
