THis is having an incredible negative effect upon programs in ML.
GIMP wont run even with Xquartz
It runs fine for tons of users. Are you experiencing a specific issue? If so please report a bug.
CrossOver does not launch Windows programs correctly, and instead shuts down
CrossOver ships their own server and does not actually use anything from Apple's X11 except for quartz-wm. I suggest you contact Codeweavers for access to test versions of Crossover that will work on Mountain Lion.
MacPorts is useless (Not just because of X11, but because of changes to Xcode)
Yeah, there are a few bugs to be worked out
As with most updates, MacPorts will need to adjust to this change. We're working on it, and you can follow the thread I started on macports-dev for specific information.

This isn't just a removal, where reinstallation via XQuartz fixes things all nice and neat.
Please use the latest rc version of XQuartz (currently 2.7.1_rc4). As you probably discovered, earlier versions (like 2.7.0) don't fixup some things.
All the underlying launchd mechanisms that made the Apple X11 function so well with previous versions are gone as well. All the automatic $DISPLAY setting methods, for example, are ripped out. Installation of the XQuatrz package does nothing to fix that.
That's not true. XQuartz sets $DISPLAY for you (and always has). You need to logout and log back in to get $DISPLAY. This is mentioned on the download page and in the installer.

Since there's no way to get the old startx methods to work anymore -- because they're just gone.
What do you mean? The entire startup sequence for XQuartz is based on xinit and startx. If you're having issues, please file bug reports with specific information.
This is not something they'll be fixing. I hope XQuartz manages to do something about it, but there are no guarantees. This is the kind of thing that can become orphanware in a hurry.
About what? File bugs, and they'll get fixed in time. I can't fix bugs I don't know about
😉

Bingo! There was no point in Apple shipping it since we could get the latest version via open source. Only problem here is that Apple is no longer guaranteeing that X11 will work when a new version of the OS ships.
Note that All of X11 is based off of public APIs except for a small set of "private" APIs in a library that lives at /usr/lib/libXplugin.dylib ... as long as that library is updated for future releases, it should "just work"
Its possible for OS X to break X11 and the open source XQuartz team to have to quickly produce an update to support new operating system releases.
Yeah, but seeing as how the "open source XQuartz team" is 99% @apple.com, I think that's probably not difficult...
Its probably not much of a concern if you wait a couple weeks after the release of a new version of OS X to upgrade. They should have any required updates available to XQuartz within a few weeks (or possibly before) release of OS X, given the availability of developer previews.
Actually versions of XQuartz that work with Mountain Lion were released well in advance of Mountain Lion. You just need to be using the rc versions of XQuartz. 2.7.1_rc4 works great with it.
----------
Can someone confirm that Matlab works with XQuartz?
Yes.
----------
Make no mistake. XQuartz doesn't work in its present form on ML.
Don't know if I can make it plainer.
File bug reports.
Yep. Installed. Tested. Failed. Debugged. Failed. Next?
You installed the wrong version. Install 2.7.1_rc4.
----------
Is the fact that removing X11 causes various applications to break not a valid concern?
It is a valid concern. Please report problems.
I occasionally use GIMP, but according to various posters, it no longer works, even with XQuartz. Will you be buying me a similar photo editing application so I can work with my photos when 10.8 comes out?
No, but I will fix bugs if you report them. gimp runs fine here, but I'm by no means a gimp power user.
