by Jeremy Huddleston 29 Sep '11

29 Sep '11

I just uploaded 2.6.0_beta2 which pulls in all the updates in X11R7.6 RC1 plus the xorg-server 1.9.3 RC1 server. You can obtain the update by checking for updates in the X11 menu or directly here: http://static.macosforge.org/xquartz/downloads/SL/XQuartz-2.6.0_beta2.dmg The full ChangeLog is available here: http://xquartz.macosforge.org/trac/wiki/ChangeLog The only XQuartz specific changes I want to address before making rc1 are related to RandR. If you find any regressions or serious issues, please let me know. --Jeremy

Getting bad DISPLAY value during use of 2.6.1-2.6.2 (not with 2.6.0 & before).
by sci-fi＠hush.ai 24 Apr '11

24 Apr '11

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.

(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.

XQuartz 2.6.1 (xorg-server 1.9.3.902) fails because tcsh crashes
by Peter Dyballa 24 Apr '11

24 Apr '11

Hello Jeremy! There was an interesting failure after installation of the latest security patches. In tcsh's history file were items like: l /System/Library/Fonts/ otfinfo -i /System/Library/Fonts/儷黑\ Pro.ttf otfinfo -i /System/Library/Fonts/ヒラギノ明朝\ ProN\ W3.otf otfinfo -i /System/Library/Fonts/ヒラギノ明朝\ ProN\ W6.otf otfinfo -i /System/Library/Fonts/ヒラギノ角ゴ\ ProN\ W3.otf l /Library/Fonts/ which finally and at once led to Segmentation fault (core dumped) Exit 139 Other software failed as well, but Terminal, xterm, or the shells in GNU Emacs not... (Discovered by running /Applications/MacPorts/X11.app/ Contents/MacOS/X11 in Terminal.) Since it happens/happened on Leopard it's probably useless to report the tcsh behaviour as bug... -- Greetings Pete Real Time, adj.: Here and now, as opposed to fake time, which only occurs there and then.

XQuartz 2.6.2_beta1
by Jeremy Huddleston 12 Apr '11

12 Apr '11

I just released a new beta of XQuartz. You can download 2.6.2_beta1 by checking for updates within X11 if you are on the beta update feed. To get on the beta feed, run the following: defaults write org.macosforge.xquartz.X11 SUFeedURL http://static.macosforge.org/xquartz/downloads/sparkle/beta.xml You can also download the dmg directly here: http://static.macosforge.org/xquartz/downloads/SL/XQuartz-2.6.2_beta1.dmg With this update, we've moved up to the 1.10.x server branch, updated to xrdb 1.0.9 which fixes CVE-2011-0465, and pulled in a ton of fixes for quartz-wm. The new quartz-wm should work much better with various window behavior and decoration hints such as steam windows running in wine. For the full list of changes, check out the ChangeLog: http://xquartz.macosforge.org/trac/wiki/ChangeLog Thanks, Jeremy

XQuartz 2.6.1_rc1
by Jeremy Huddleston 01 Apr '11

01 Apr '11

I've just uploaded 2.6.1_rc1 for both Leopard and Snow Leopard. This pulls in a few more fixes for RandR and should address the "xterm changes background color" issue that cropped up a few releases ago. There are still a couple RandR related issues that I want to tackle before the final release. Please give it a whirl and let me know if there are any regressions. Thanks, Jeremy http://static.macosforge.org/xquartz/downloads/Leopard/X11-2.6.1_rc1.dmg http://static.macosforge.org/xquartz/downloads/SL/XQuartz-2.6.1_rc1.dmg
