And when I then go to TTY2, instead of finding my session, I find the console login screen of TTY2. So now I am basically unable to use fullscreen in VLC (it doesn't appear to happen when using anything else) because my session seems to get destroyed every time. And I am not sure if this is a bug with VLC or Xorg, so I thought I should report it under both, I am also not sure if it would just happen with VLC, but so far that has been the only fullscreen application to have this happen at the same time as it running. --- OS Information: No LSB modules are available.
