[linux-audio-user] dssi: 2 questions

hi folks, i've installed rosegarden on my mandriva 2006. then i've download dssi from "thac's rpm" (www.mde.djura.org/index2006.0.html). in particular i've installed these files: dssi-0.9.1-0.1.20060mde.i586.rpm dssi-vst-0.3.1-10.mdk2006.0.mde.i586.rpm libdssi0-0.9.1-0.1.20060mde.i586.rpm libdssi-vst0-0.3.1-10.mdk2006.0.mde.i586.rpm libfluidsynth-dssi0-0.9.1-0.1.20060mde.i586.rpm liblo0-0.22-0.1.20060mde.i586.rpm after the installation process ended, i've read the file "/usr/share/doc/dssi-0.9.1/README". i've run first jack and then "less_trivial_synth", "trivial_sampler" and "jack-dssi-host less_trivial_synth.so". my dssi-path was set by default and so all these plugins started (i saw this by looking on jack connections) and i managed also to play "less_trivial_synth" by my m-audio keystation. i've managed also to rec and play with rosegarden. the problem is that in all the cases, the gui of these soft-synth doesn't appear! how can i solve the problem? thank you bye emanuele ps. sorry if my english isn't very good.....
