In Linux, I am trying to run a transparent window demo using JNA, and am
getting the following stacktrace:
Exception in thread "main" java.lang.UnsupportedOperationException: This X11
display does not provide a 32-bit visual

com.basis.techcon07.TransparentWindow.main(TransparentWindow.java:108)
I’ve tried this on several configurations, including Gnome on Fedora Core 2
and Xfce and KDE on Ubuntu 6.06.1. From what I’ve read, most videocard
manufacturers (Nvidia and ATI come to mind) make 24-bit color Linux drivers
for their videocards, but not 32-bit ones due to the fact that the last byte
is usually used for transparency.
Has anyone had success with transparent and shaped windows under Linux? Is
there a specific configuration I need in order to get things working?
Thanks in advance!
