animate on linux/unix
Dear Ferret Users,
another problem is -- thank's to Kevin O'Brien -- solved. Since it might be of
interest to others, here are the description and the solution:
Problem: Using a command sequence like (or similar to)
repeat/l=1:10/animate shade data
(ferret 5.40) shows only the first frame.
All other frames of the sequence are empty pages.
Reason: The xserver option 'backing-store' is probably disabled.
xdpyinfo
returns
options: backing-store NO, save-unders NO
However, it should return
options: backing-store YES, save-unders YES
for successful animations.
Solution:
Add '+bs' to enable backing-store in the file
/etc/X11/xdm/Xservers
to the line where the X-server is started, e.g.:
:0 local /usr/X11R6/bin/X +bs :0 vt07
Then restart your X-server.
Good luck!
Sincerely,
Patrick Jöckel
