Detects Display But Blank

MisterSpock · 12-12-2011, 10:26 AM

On the last beta and the release Version of 1.7 I don't see a screen. The second monitor (2 Apple Cinema Displays) is detected, but the display stays black. Rebooting, reinstall etc. did not solve the problem.

Attached you find the debug info... by the way - the problem occurs since Beta 5 (b5). I hoped it is fixed in the final version, but does not seem to be..

This did not work for me but just found it somewhere else

Unplug the adapter from the USB port.
Disconnect the DVI cable from the DisplayLink adapter.
Power off the display you normally use with the adapter.
Connect the USB cable between your computer and the DisplayLink adapter.
Wait for your displays to flash (as if a new display was connected).
The light on your DisplayLink adapter should be on now.
Connect the DVI cable to the DisplayLink adapter.
Wait a few seconds and then power on the display connected to the adapter.
If this process doesn't work, try a reboot and repeat the process once Finder finishes starting up.

I tried your process and it still didn't work - sorry. I tried it several times.

Thanks for debug info. Could you please change the verbosity level to VERBOSE (menu advanced->verbosity) and re-collect the debug info (unplug and replug the adapter before collecting the info). Thanks

hi new logs as requested

Thanks for all your hard work. This has been great software since I started using it last year. I am having a similar blank display issue with Lion 10.7.2 and a mimo monitor (it's not detected, though). I just upgraded from SL and this is just one of Lion's many annoyances. Attaching the diagnostic zip below.

We checked your logs and it seems that for some unknown reason, the driver is not correctly installed. Here is the error message in the logs:
/System/Library/Extensions/DisplayLinkDriver.kext/DisplayLinkAgent/USBNivoListener", ...): No such file or directory

Could you please try to uninstall the driver and reinstall it? Thanks
