Hello, I think DISPLAY is getting a weird value on my system here. We've completely rebooted, and this is still occurring on my system with any of the 2.6.1-2.6.2 incarnations of Xquartz. (IIRC this didn't happen with 2.6.0 and earlier.) Presently I have the beta1 of 2.6.2 installed and trying to get it started-up here. (Yes I did re-run the installer for 2.6.2_beta1 after the 10.6.7/etc system updates.) The user's env-var matches what launchctl returns: $ launchctl getenv DISPLAY /tmp/launch-s9kPWX/org.x:0 $ _ There _IS_ a critter placed there: $ ls -al /tmp/launch-s9kPWX total 0 drwx------ 2 scifi wheel 102 Apr 24 10:06 . drwxrwxrwt 11 root wheel 510 Apr 24 10:33 .. srwx------ 1 scifi wheel 0 Apr 24 10:06 org.x:0 $ _ But I think this DISPLAY value produces the first part of the error log when I launch Xquartz.app from the Dock: [snipped from system.log] --start-- Apr 24 10:33:12 scifi [0x0-0x8b08b].org.macosforge.xquartz.X11[63105]: X11.app: DISPLAY ("/tmp/launch-s9kPWX/org.x:0") does not match our id ("org.macosforge.xquartz"), unsetting.

(There is no critter named /tmp/.X11-unix (shown via ls -al) presently on my system. The /tmp dir itself does have root:wheel ownership with "drwxrwxrwt" flags.) (I have disabled Spotlight via one of the 3rd-party tools. GNU 'find' and 'grep' are good enough for me without extra overhead .) (BTW I have env-vars for T[E]MP[DIR] all set to the /Volumes/RamDisk/tmp path, in case you're wondering about the font_cache.lock msg above.) (When this does work, I'm also still been experiencing my "semi-stuck H/h" keyboard key as noted in my bugreport #443, now occurring on 10.6.x also -- 'h' tells Pan to show/hide headers on Usenet posts, so this is rather unnerving for me.) … I'm wondering if the _original_ X11 subsystem is somehow inserting its "org.x" string into DISPLAY, somehow? But why won't Xquartz fix it? What should I do, please? Thank you.
