Well inexplicably I now have Realsoft running under Linux
Suse had everything needed except the ATI driver. The config says 3D acceleration isn't available - possibly because there isn't a version of the driver for my exact version of xfree??
Suse also says I have TCL but the setup says no. Will investigate later.
Screen displays in 3 modes ok and renders the trout sample scene. I can't see how to access my windows files from the file loader.
The main weirdness was alt+rightmousebutton which increased the size of my viewport to the right, rather than zooming. Is this normal? Ok I'll go away and read the docs
Getting internet to work seems a bigger challenge. But without internet one gets a lot more work done, so that might be a benefit.
I'm sure I won't have any more problems ever so ... until the next time.
