Apple Removes X11 in OS X Mountain Lion, Shifts Support to Open Source XQuartz

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.

THis is having an incredible negative effect upon programs in ML.

Yeah. What they ought to do is release some sort of "Developer Preview" 5 or 6 months ahead of the release of the new OS so that developers heard about these things and had time to produce fixes.

Is ML really an update? It seems like a downgrade in many respects.

Stuff like this should really be optional. Not everyone uses it.

Do you really know what you're talking about? It seems like you really don't know what you're talking about in many respects.

I guess this will be another "dumbing down" thread. :rolleyes:

Anyone who was using X11 on OS X (myself included) never really bothered with Apple's version anyhow and went straight to XQuartz.

Too early to be worried...

So, the facts are:


* Xquartz is the open source X11-compatible window server for Mac OS X
* Xquartz is maintained by Apple-employed developers. It's an Apple-sponsored open source project.
* The 'X11' app bundled with various OS X releases has historically been a snapshot of the Xquartz code, renamed and integrated with the Mac OS X release.
* There was some extra 'glue' which made the Xquartz snapshot known as X11.app behave extra nice with OS X ($DISPLAY setting, etc)


So the actual change in Mountain Lion is that:


* Apple will no longer be bundling re-labelled Xquartz versions with OS X.
* OS X will instead prompt the user to download Xquartz when an X11-dependent application runs.


Now, clearly there's been a shift in responsibility here. The OS X team no longer take responsibility for integrating Xquartz (branded 'X11') into OS X major releases.

Rather, the Xquartz team (still Apple employees, remember) need to build up their process for producing releases independently of the OS X team. This is where the 'glue's got lost. Whatever OS X used to do for X11.app/Xquartz, Xquartz is now going to have to do for itself. From their point of view, it's almost certainly too early to start down that road since ML is still such a moving target. Hence the lack of integration in the present DP state.

I'm failing to see the malice, neglect or otherwise here. Rather, it's letting the Xquartz team control their schedule and deliver their updates independently of OS X without having to rely on people seeking out and installing Xquartz on their own.

Bear in mind also that the third-party developers will also take a little bit to adjust. They've been used to being able to test against 'the X11 that comes with <OSX_VERSION>. Instead, they'll need to test against the current release of Xquartz.

We're only about 24hrs into Mountain Lion's public history... so let's give everyone involved a chance to sort things out.

Dont know why its not, but it does not work at all in ML.

Just remember, ML is just a beta at this point. That's the point of betas: find out what doesn't work & fix it.

...Didn't want to quote whole thing to I'll settle for "Mass pwnage to all the haters." ...

Am I the only one who was overjoyed by Jeremyhu showing up and completely owning everyone complaining about issues?

You sir rock.

Gee, thanks, Apple, for continuing to not support legacy technologies and destroy people's data and intellectual property. Way to go...

If every company spent all their time building in support for outdated legacy **** that only 20 people still use

X11 is not legacy technology. Geez. It's just that Apple was doing a poor job of shipping it by default with OS X, with everyone needing support for it already relying on XQuartz's efforts in the matter.

It's a good thing Apple removed it and tells people to go get XQuartz.

Love the people who act like 10.8 was pushed out to all users publicly.

Love em.
