well it seems you were correct. I removed that package, and then I was able to install the other, so that is good. X seems less laggy now, so that is good.
However, now when I try to run totem, I get an error, so that is not good. It says:
resource busy or not available
how do I go about fixing that? I think it has to do with the configuration of totem or whatever the backend of it is, but I'm very new to this and have no idea how to fix this. any ideas?
