[Libdlo] Issues Starting X

[Todd Grayson]

Thank-you for the quick response. Actually I am connecting the displaylink device directly to a thin client. As well, I did have it working at one point but went through a number of configuration changes in an attempt to dynamically set the resolution on a vga device.

I have since started fresh, rebuilt the kernel and the kernel module. Unfortunately, since then I have gotten the repeating message. I suspect that it was a change in the kernel config but I have no idea what I might have changed in the kernel config.

Hi Todd,

Are you running a mini-monitor that's powered over the USB cable, or
do you have a USB hub with several devices attached (including the
DisplayLink adapter)?

If it's a mini-mon, try connecting it to one of the USB ports directly
from your laptop (which can typically provide more than the spec'd
500mA).  If it's an adapter off a USB hub, move some devices directly
to the PC, or make sure the hub is self-powered with enough amps for
all the devices attached.

A DisplayLink device alone shouldn't pull more than the 500mA limit,
although some mini-mon designs might (depending on screen size,
backlight, touch ....)

Best wishes,
Bernie
