We are running Sun java 1.4.2_08 on RHEL 4 workstation.
We recently configured a workstation with six heads as three virtual
screens (0.0, 0.1, 0.2) using twinview. The workstation is a Dell
with a dual port NVIDIA Quadro FX1400, and a quad port NVIDIA Quadro4
All the normal X programs we run behave as expected. They open their
displays on the screen specified by the DISPLAY variable, either
:0.0, :0.1, or :0.2.
The java programs all open their displays on :0.0, no matter what the
DISPLAY variable is set to. If DISPLAY=:0.1, or DISPLAY=:0.2, java
opens it's window on :0.0.
Even stranger, we have a java menu program , call it treepm, that
runs other programs. If we run treepm from :0.1, it opens its display
on :0.0. But, any normal Xwindow program run from the treepm menu
display will open on :0.1.
When we had this system configured as a single virtual :0.0 display
using twinview and Xinerama, everything worked fine. But, of course,
the only display was :0.0.
Has anyone seen this problem before, or anything like it?
