"Subject: Jumpy Cursor fixed by 10.5.7 (as of one reboot!)
Aloha Mike! The update fixed the DP events error (repeated console entries) and jumpy cursor as of my first reboot. (Macbook with Mini Displayport dual-link DVI adapter used w/30in Cinema Display.) Hasn't worked (smoothly) from day 1. Working today (after 10.5.7). Hurray!
If it breaks subsequently, I'll email you.
-Scott T."

Hopefully it is really fixed. (Apple did mention 10.5.7 had improved performance/video with later Macs w/Nvidia graphics.)

"Seems like 10.5.7 has broken the current beta display link drivers. At least on the Nanovision UM710 screen (7" USB display link powered mini monitor).
I'm running an original core duo macbook.
Console logs show the following:

13/05/09 9:42:35 AM com.displaylink.usbnivolistener[111] 2009-05-13 09:42:35.891 DisplayLinkManager[497:10b] KensingtonDock::KensingtonDock: can't register the button.

Current beta drivers from Displaylink are from January this year, so it's probably time for them to update them.

(It may not matter (not a fix for a driver issue) but I asked if he'd tried disconnecting/reconnecting the USB device. (Sometimes has helped in the past with USB device problems after an update - for example some printers, UPS' USB connection, etc.))
Yup, tried all the obvious things. I originally had it running thru a hub, so I tried direct into the macbook with the same result. Even tried swapping cables, rebooting a few times, the usual stuff. A shame really as they are really useful monitors (when they work) and great for IM, chat, video etc.
It is getting detected by the system but looks like the driver isn't loading correctly, or can't correctly identify the device now, hence isn't working.
Oh well, back to waiting :)

I also wrote to ask if he had tried a driver reinstall. (And suggested he write the developer to report the problem.)
(Update: See Mike R.'s May 19th Follow-up on DisplayLink 1.1.2beta/Mini Monitor driver and 10.5.7 for notes on how he got it working again.)
I also wrote OWC to ask they report back after testing with 10.5.7 now that they offer a USB Display adapter and they replied their tests with the v1.1 (non-beta) Displaylink driver worked fine in the last couple builds of 10.5.7 and the final release, but they didn't use the Beta 1.1.2 driver (required for Mike R.'s adapter).

• ATIRadeonX2000 driver updated to 1.5.44.13 (was 1.5.42.8 in 10.5.6 build 9G3553)
• Broadcom USB Bluetooth HCI controller driver updated to 2.1.6 (was 2.1.5):
• AppleAirportBrcm4311 updated to 3.6.3 (was 3.6.2, but same last modified date/time)
• AudioIPCDriver 1.0.6 (was 1.0.5, " )
• AppleGraphicsPowerManagement 100.6.5 (was .2, " )
• AppleIntelCPUPowerManagement 76.0.0 (was 71.0.0, " )

I've not used 10.5.7 very much yet, and just applied the Safari 3.2.3 update as well. (It also requires a restart.) I don't have an Nvidia GPUs currently in any Macs. Although I don't play WoW personally a reader that does said the "ATI shadow quality bug' mentioned by blizzard has been fixed:

(regarding ATI shadow quality bug)
"It was fixed. And in fact current WoW version detected the presence of 10.5.7 and re-enabled the preference they had functionally disabled if client detected 10.5.6 with an ati driver running.
-Adam W."

FYI - here's a note from Chris Bentley (ATI/AMD) on ATI (HD2600 and up) driver changes/improvements in 10.5.7 (from the OpenGL mailing list)

"I figured it would be useful to list the main changes in the ATI 3D drivers between 10.5.6 and 10.5.7 for the Radeon HD 2600 and later hardware:

• support for GL_EXT_gpu_shader4
• support for GL_EXT_texture_integer
• support for GL_EXT_bindable_uniform
• support for GL_EXT_framebuffer_sRGB
• support for texture fetch in vertex shaders
• lots of minor performance improvements (5-10%)
• fixes for many bugs (comment revised by request)

Cheers, chrisb"

In some quick tests on a 2009 Mac Pro (dual 2.66, 12GB ram, 4870) I didn't see any significant differences in performance in a COD4 MP (short) timedemo at 1920x1200, HQ/4xAA/no shadows. (But that's pretty high res, lower res/other apps may show more benefit.) CineBench R10 OpenGL scores were about 1% higher than 10.5.6, not much more than possible run/run varation although that's not a heavy-duty GPU test. CB R10 Rendering scores were literally the same as 10.5.6. I wish I'd done a screenshot/recording of the OpenGL extensions viewer benchmarks w/10.5.6 (thought I had but can't find them now). I didn't bother with other pure benchmarks like Xbench. Regardless, glad to see the update.

FYI to VM Fusion users: - VMware has a Blog post/warning to ATI gpu users on 10.5.7 (posted May 13th) that says 10.5.7 ATI drivers break 3D acceleration. They warn ATI GPU users that rely on Fusion to not upgrade to 10.5.7 until an update to address this is released.

If any readers see any pros or cons with 10.5.7 on your system (and/or any software/utils/addons that are broken or have an update for 10.5.7 compat.), let me know the details (include your mac info/config also.) Thanks.

Often a Safari update breaks some browser addons but not sure if that will be true for this update. (BTW - I had a reader say Safari 3.2.3 doesn't have the libxml2.2 prebinding issue that Safari 3.2.1/OS X Tiger users noted last fall.)
