I have installed XQuartz 2.7.5 on Mavericks. After that videos I play with mplayer seems to load on a separate window, all white stuck with only the audio playing. I have disabled Xquartz by disabling /Library/LaunchAgents/org.macosforge.xquartz.startx.plist and /Library/LaunchDaemons/org.macosforge.xquartz.privileged_startx.plist with launchctl.
Iwould like to know how to display the videos as it was playing before. I installed mplayer via brew. Is there a way to direct $DISPLAY to the default x server? Please help.
Thanks
Don't disable /Library/LaunchDaemons/org.macosforge.xquartz.privileged_startx.plist. That will prevent XQuartz.app from launching.
Disabling /Library/LaunchAgents/org.macosforge.xquartz.startx.plist (and relogging) will result in the DISPLAY environment variable not being set and thus automatic launching of XQuartz.app when you run X11 applications, but you can still launch XQuartz.app directly.
There is no default X server. X11 was removed from OS X in Mountain Lion. X11.app in earlier versions of OS X was just XQuartz.app with different name.
I have develop two tiny utility applications for both Windows and MAC OS X. I know how to make this disk auto-run by Window. But for MAC OS X, I've no idea how to.
Any one know about how to achieve this? Can I make ONE disk auto-run by both Windows and MAC OS X? And of cause, different OS should run different apps designed for themselves. For example, Window may run "util_Win.exe", while MAC OS X "util_MAC.app".
You can customize the background of a window by opening the window and choosing "Show View Options" from the "View" menu in the Finder. Once displayed, you can set the "Background" setting to "Picture" and then choose the picture you want.
See here for an example.
I've got an open source PyQT app, and am wanting to know if it's possible to have it enter "full screen" like other OS X Mountain Lion apps do; meaning like Safari full screen.
Or is this impossible at the moment?
How can you simulate a retina display (HiDPI mode) in Mac OS X 10.8 Mountain Lion on a non-retina display?
Search for, download, and install Apple's free Additional Tools for Xcode 8 (for previous Xcode releases search for Graphics Tools for Xcode according to your version).
Note: free Apple Developer account required.
Launch Quartz Debug application.
Go to menu: Window ---> UI Resolution.
Check Enable HiDPI display modes.
Quit Quartz Debug.
Open System Preferences.
Select Displays icon.
If using multiple display, select the configuration window on the display you wish to simulate HiDPI mode on.
Under Resolution:, select Scaled radio button.
Find a desired resolution postfixed with (HiDPI) and select it.
Your display is now running in HiDPI mode, simulating a retina display.
Source: High Resolution Guidelines for OS X
I found the following instructions. It seems to work, and it is much easier than the Quartz Debug approach.
"Enable HiDPI mode in Mountain Lion w/o Quartz Debug"
https://gist.github.com/3191869
In brief, run the following commands, log out, log on, and the HiDPI resolutions are available in the display preferences:
sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES
sudo defaults delete /Library/Preferences/com.apple.windowserver DisplayResolutionDisabled
(In my case the first command was enough; the second command just prints an error message.)
Edit: (5/31/2016)
For users trying to do this on El Capitan, please read the FAQ on SwitchRes's website. Also, if something's still not working after you did all the steps in the FAQ, consider uninstalling and reinstalling SwitchResX. That solved the issue I was having on one of my laptops.
Original:
After reading through several forums, websites, blogs.
I am here to present a solution for users with 15" MacBook Pro with Retina display connected to a Thunderbolt Display.
First of all,
Terminal command of modifying plist
Quartz Debug
Holding option and select "Scaled" in System Preferences
ResolutionTab (Mac App Store)
These methods DO NOT work for MBPr with Thunderbolt Display, for whatever reasons.
You will not see the HiDPI options to be selected.
The only tool I found that actually gives us the options is SwitchResX.
However another problem exists here.
Most users with this setup, I believe, are trying to use 1280x720 HiDPI because it's half the native resolution of the TBD.
According SwitchResX's FAQ, in some cases it is not possible to set to this resolution because of a bug within OS X itself.
Here's a screenshot for your reference:
After contacting the developer, he presented a workaround - adding one more pixel - which worked for me.
Install SwitchResX and open it from System Preferences.
Go to Thunderbolt Display tab, and add a Custom Resolutions with Scaled Resolution at 2562 x 1440
Here's a screenshot
Save using command + s. (or simply close the window and use the prompt up)
Restart the laptop.
Go to SwitchResX and select the new custom resolution in the Current Resolution tab. (Sometimes it doesn't show up right away, play around with it and it should.)
Here you go.
I hope this answer gets to users with this setup because it is really frustrating to use 16:10 resolution on a 16:9 display.
For those unable to enable HIDPI on rMBP or new MBA, I experienced the same on my rMBP 15" with Air Display. I solved the problem by installing SwitchResX. With the boolean setting enabled as shown in the referenced gist, the HIDPI setting shows up.
Dragging seems a little laggy in Air Display, but otherwise works great.
Try this
sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES
[from here]
If your monitor supports it, it may also be worth setting the DisplayPort version to 1.1 instead of 1.2.
I have a late 2010 Mac Air with a Samsung S27D850 display and had all sorts of intermittent resolution switching issues until I made that change.
As for me its pretty good app that give you opportunity for changing resolution any that you want.

This app resolved all my problems with resolution.
I have created Perl/Tk application for OS X compiled using ActiveState PDK PerlApp 8.2.1. The application requires X11 to work properly on OS X, and everything works fine on my own computer (OS X 10.4.11) and others report it working well on OS X 10.5 and 10.6.
But, I have also received several reports from users, for example on 10.4.11 and 10.6.7, that after starting the application, the program seems to run but no main window appears.I have created Perl/Tk application for OS X compiled using ActiveState PDK PerlApp 8.2.1.

But, I have also received several reports from users, for example on 10.4.11 and 10.6.7, that after starting the application, the program seems to run but no main window appears.
(Just to clarify the meaning of "seems to run", users can launch X11 (so it's installed!). Also, after launching my application, a new X11 menu bar appears and they can click "About..." and can see the "About..." window for my application.)
I cannot replicate the bug here and the users say that no errors appear on the Terminal command line when they launch the application.
Has anybody experienced a similar problem and know a way to fix it? It seems to be an issue with X11, but I am happy to change my own code to avoid this issue.
I guess the first thing to check is that they are launching from the X11 terminal, rather than the normal one. (and that they have X11 installed).
PerlTK might be hiding the errors in that case?
