XQuartz/X11 on Mavericks does not work on my extended desktop.

Another problem is that if a window is opened on inactive desktop it can go under the top bar and become inaccessible too.

I, among others, filed a bug to Xquartz ( http://xquartz.macosforge.org/trac/timeline ), they said it is Mavericks problem and looked like they didn't want to bother at all. To be honest, I really, really don't like it. X11 system was, probably, the biggest reason for HE/research to move towards Apple/OSX systems. Now Apple does not support X11, Xquartz people don't care, the last update to Xquartz was more than one year ago, bugs accumulate, and it all seems like we are left with unusable but expensive equipment and have to go back to scientific linux/ubuntu etc...

A work around is to go into System Preferences->Mission Control and uncheck Displays have separate spaces.

This will put you back into a sort of legacy mode. The new dual monitor features of Mavericks won;t work but X will behave as it did before.

According the mailing list this is a dual problem. There are some changes that need to be made to Xquartz and there are problems in Mavericks. The Xquartz team can only fix there end. Apple will need to fix their end to resolve this as well.

BTW if you are not aware of it there is an Xquartz mailing list where question like this are better asked

Now Apple does not support X11,

Apple's involvement with X11 has not changed. The X11 development was always separate from the OS team.

What the change with Lion did was to make this separation official. This freed up the X team to work on their schedule and not have to rely on OS releases in order to add features or fix bugs.

You should subscribe to the mailing list I referenced in the above post. Your questions and concerns will receive a more direct reply.

Just reinstall Xquartz and it works perfectly

Reinstalling did not help, nor did upgrading to 2.7.5_rc4.

Same problem here, it does not work, windows are lost. To recover them, I had to unable "Video Copy" (I don't how it is named in English, sorry, I mean making both screen display the same thing).

Yes, this functionality is indeed broken in Mavericks. Same setup worked fine in Snow Leopard.

Software OS X 10.9.1 (13B42); XQuartz 2.7.5 (xorg-server 1.14.4)

This is broken in Mavericks. It would be great if Apple could fix this.

OS X 10.9.1, and xQuartz 2.7.5

Same problem, also I'm having a hard time accessing the menu bar at the top of the screen, but that may be because I disabled auto hide before upgrading to mavericks 😝

I found this work-around, create a small script for where ever you want to open a xquartz window:

Start Xquartz and then run the following script in the first Xterm window

This script opens a light-green window on a monitor to left of my laptop

#!/bin/ksh

# ------------------Down from top-------------------|

# ------------------In from left edge------------| |

# ------------------# of charcters High------| | |

# ------------------# of charcters Wide--| | | |

if [[ ${TERM} = "xterm" ]]; then

/opt/X11/bin/xterm -fn 6x12 -geometry 120x60+810+20 -sl 1500 -vb -bg lightgreen &

else

echo "This is not a X-Window . . . . "

echo " PLEASE start Xquartz and restart your script from the X11 window."

fi

I use a variation of this to open 60 small windows at the same time on 60 different systems on a 30 inch monitor for password changes.

Thanks, Vicryan. That helps with the xterm not coming up under the top bar of the monitor. But it dos not allow the xterm window to smoothly transition from one desktop to another.

I also encountered that one cannot drag an X window into an extended desktop. I also can confirm the disabling of displays having separate spaces work. However, an additional workaround that allows you to keep the spaces feature in place is to use Mission Control to move windows from one desktop to another.

Thanks for that simple but brilliant workaround! Don't know why I didn't think of it, but it works fine with just the very minor annoyance of having to use the 4-finger scroll-up, then drag/drop. And this way you still get to have separate desktops/menus on the two screens.

I typically used Control + Up.

I have upgraded to 10.9.2, and the issue seems almost entirely resolved, without the need to upgrade XQuartz. The window cannot stradle two displays, but can be moved between them. It is possible to make a window "disappear", but it would mean you grabbed the window by the very tip of the left most edge of the window, and then moved it just so that the mouse pointer is not quite into the other desktop yet.

I'm adding a reply to this thread because it's the closest I could find to my problem. I use anywhere from 1 to 4 monitors, and when I start up xquartz, the window appears front and center on my main display. The issue is, if I plug or unplug a monitor, the window goes off screen and I can't get it anymore. I can see it in mission control, and I move it in mission control, but no matter what I do, when I leave mission control, it's still off screen. Restarting doesn't help because the window position is saved - I have to get back to the exact configuration with the same monitors I used last to see the window again. The xquartz people say it's an apple issue and won't fix it.

I found that if I remove the xquartz plist file ( ~/Library/Preferences/org.macosforge.xquartz.X11.plist), then the next time I open it, I can see the window again. It's a pita to have to remove this file every time I'm using a different monitor configuration, but at least there's a workaround.
