 After fancy screen artifacts, the screen went black, and I had to kill 
 the session.
 
 Looking into Xorg.0.log, I see lots of
 
 [412018.872] (WW) RADEON(0): Page flip failed: Invalid argument
 [412018.921] (WW) RADEON(0): flip queue failed: Invalid argument
 
 and xdm.log talked of failed memory allocations (there is no backup 
 file, so I don't have the exact wording).
 
 Cheerio,
