15" core i7 displaylink woes

brownpants · 05-16-2010, 04:24 AM

I just wanted to report that I'm experiencing the same strange behaviour. New 15" MBP with i7. Fresh install of Snow Leopard 10.6.3.

Even when the DisplayLink adapter is not connected, but my external monitor is connected via mini-displayport, my display will lock up (though I can see the mouse cursor and move it around) if I unplug the mini-display port.

When I boot my MBP with no external monitor (no mini displayport or displaylink) I see my desktop for a split-second and then I get a blue screen with horizontal bars, and again I can just see my cursor and move it around.

Uninstalling the DisplayLink beta drivers fixes the problem.

Same problem here. I had to boot in single user mode to uninstall the DisplayLink drivers...

Same issue but...

Instead of having to reboot or uninstall drivers, a quick fix is simply take a mini-DVI adaptor and plug it into the dvi mini port. Voila - -your screen will work - -regardless of whether or not the DVI is connected to an external screen.

I simply plug mine in for a second and pull it out and my screen comes back to normal (no more blue or colored snow).

A work around until a new beta version is available

Same thing for me, on my macbook pro i5 10.6.3. I'll have to test out the workaround of plugging in the mini display adapter for now.

Same issue here with 10.6.3, a brand-new MBP i7 15", and the 1.5 driver. When plugged into multiple monitors, everything's great. But booting the MBP alone gives me the alternating blue lines.

So at this point, my laptop is useless unless attached to an external monitor. Which sorta defeats the whole "laptop" thing.

Disabling Automatic graphics switching fixed my problems as well.

Disabling automatic graphics switching didn't work for me and also the other trick of connecting the mini display adapter to fix it also didn't work. I need to uninstall the driver when I leave work and re-install it each morning when I get back.

Same problems here with a macbook pro i5.

I sincerely hope we'll see a good driver soon.

I had the same problem with MBP i7 - 10.6.3
MBP freezed when automatic graphic switched, I had to reboot in save mode and uninstalled the driver.

it works when disable auto-graphic switching and keep the machine running with NVIDIA only.

Hope to get something which will work very soon. I need my third monitor.

I get this exact same behavior with the 1.6beta2 driver installed.

15" Core i7 MBP / high-res, brand new.

It seems like whenever the MBP tries to switch from the NVIDIA to Intel HD graphics processor, something with the DisplayLink driver is freaking it out.

This handy tool will tell you which adapter your MBP is currently trying to use:

It'll also tell you what apps are dependent on the NVIDIA GPU and causing it to be used (among them, an external display, which is why everything is fine when you run with an external monitor).
