There are two mouse
pointers after the remote
system is accessed.
This is normal. One is the
local console’s pointer;
the other is the remote
system’s mouse pointer.
You can shrink the non-functioning pointer
so that it is almost invisible. See
, page 71 for details.
The display on the
remote console is
distorted and performing
an Autosync doesn’t
resolve the problem.
Autosync is unable to
ascertain the proper
resolution.
1. Switch ports to a port with a different
resolution, then switch back.
2. If the above didn’t resolve the problem,
change the resolution and refresh rate
for the system running on the port.
Afterward, you can either run at the new
resolution, or switch back to the original
resolution.
