15" core i7 displaylink woes

[sameerwahid]

Hi all,

Having a problem, hoping for some help. I have a Lenovo M01061 Displaylink adapter that I'm trying to use with my new core i7 MBP with 1680x1050 screen. I'm having the following problem, that happens with 1.5, 1.6b1, and 1.6b2:

When I use my laptop at work, with a DVI and a DL connected monitor, everything is fine and all three displays work. When I unplug my computer from the external monitors and use it without DVI or DL, the laptop screen is filled with "coloured snow" and the computer is unusable.

If I boot the laptop with no external display connected, I get coloured snow instead of the login page (I can see grey Apple startup screen just fine).

If I boot the laptop with an external display connected by DL, the laptop screen is solid blue (no snow) and the external screen stays in power save mode.

If I boot the laptop with an external display connected by DVI, both screens work fine.

Uninstalling the displaylink driver makes everything usable again, so my solution thus far has been to install the driver every AM and uninstall it when I go home.

None of my displays are rotated. One possible cause is that I migrated my hard drive (SSD) over from my old MBP (mid 2007) and then reinstalled Snow Leopard from the DVDs that came with the new MBP. Everything was working just find on the old MBP with respect to Displaylink.

Also, is there a way (key combo, etc) to prevent the DL drivers from loading at boot? It would be handy to have in case I forget to uninstall the drivers and am on the go!!

Thanks,
Sam
