Does anyone know if this is possible? I'm a Star Trek fan, and there's this screensaver that's for Windows that mimics a Star Trek systems panel, and I'd love to have that on Ubuntu (so would some of my friends).
Many Windows screensavers can be run in Wine.
Assuming your screensaver is stored in your Downloads folder, just run
Windows screensavers have not been integrated into Linux so you won't be able to easily set them as your screensaver.
You could also try installing
Possibly via Wine; Windows screensavers aren't nicely compartmentalized like NDIS drivers, they're ordinary Windows programs with a different extension so Windows will know to install them as screensavers.
