[Libdlo] Error with compiling displaylink-mod under ubuntu 9.10 / Error with xrandr screen rotation of displaylink screen

[Bernie Thompson]

Hi Andreas,

The missing definitions come from the drm_edid.h header, which usually
is distributed with displaylink-mod (for ease of compiling).  It's a
copy from the Linux source tree /include/drm/drm_edid.h.

Perhaps your make environment is somehow picking up an older version
from the kernel source/header tree?

By the way, where are you grabbing your copy of displaylink-mod from?

The current X server has limited RANDR support -- no way to do rotate
yet.  The hardware has no special ability to do it - so it's a
software implementation issue.  Neither udlfb or displaylink-mod have
any code to help yet.  Any patches are definitely welcome.

Thanks for trying this out and reporting.

Best wishes,
Bernie
