| Dear X11 experts
I have been having trouble getting an X window for some time. The symptom suddenly started about 3 months ago with Mavericks and the same thing is happening in Yosemite. During all this time I have not changed X11 - it’s XQuartz 2.7.7 (xorg-server 1.15.2). I re-installed it after updating to Yosemite.
With Yosemite, my application exited with Error: Can't open display: /private/tmp/com.apple.launchd.TUuKDjPf4E/org.macosforge.xquartz:0
I then changed DISPLAY=:0 and this time it hung, consuming 100% CPU. My code is void G4OpenGLXViewer::GetXConnection () { dpy = XOpenDisplay (0); if (!glXQueryExtension (dpy, &errorBase, &eventBase)) { and the traceback is #0 0x00007fff83ca4bf1 in _pthread_cond_wait ()
#1 0x0000000106e5efec in _xcb_conn_wait ()
#2 0x0000000106e5fd9d in _xcb_out_send ()
#3 0x0000000106e5fd3e in xcb_writev ()
#4 0x0000000106ea5b9a in _XSend ()
#5 0x0000000106e9d63b in XQueryExtension ()
#6 0x00000001056b1674 in glXQueryExtension ()
#7 0x000000010044c05b in G4OpenGLXViewer::GetXConnection() at /Users/johna/Geant4/dev/geant4/source/visualization/OpenGL/src/G4OpenGLXViewer.cc:154
This is the same symptom I was getting with Mavericks.
Ideas invited!
