Hi List,
Anyone with displaylink/udl experience who could shed some light on the
subject? How do you go about setting up displaylink adapters/displays?
I'm trying to set up a Lenovo USB display ("udl0 at uhub1 port2
DisplayLink Lenovo LT1421") to work alongside my laptop, but can't get
them to work together -- it's either one working or the other, but
never both.
If I add a following section to (otherwise non-existant) xorg.conf:
Section Device
Identifier "Card0"
Driver "wsudl"
Option "Device" "/dev/ttyD0" #<--- ttyD0 first created with MAKEDEV
EndSection
then I get properly configured USB display from X, but the builtin
display is switched off (and never even mentioned in the logs, or
RandR). If I add the builtin to the xorg.conf (as "Card0", and move USB
to "Card1") then X ignores wsudl driver completely and never mentions
it in the logs, and only activates the builtin display. There are no
errors or warnings mentioned.
I must be missing something simple -- I found a couple of emails from a
while ago on this list with similar issues, but the solution that used
to work in 5.2/5.3 (put both cards/screens in xorg.conf, like I tried)
doesn't appear to work here.
(Also, what would it take to make it hot-pluggable, so I don't have to
fiddle with xorg.conf?)
Thanks
Bojan
