  Mmm. That was on Mageia-2 on the laptop.
    I've now installed Trinity on the Mageia-2 on my desktop, and that 
problem is not occurring.

Both Mageia-2 installs were from the same .iso, but on the laptop I had 
not done a s/w update before the Trinity install.
  Could that have caused the problem? Anyting else I could try?
