  Hallo
  Just after the installation of the Edubuntu 20120727 amd64 build, at the 
restart the graphic is seriously corrupted and the syslog is full of:
  
  Jul 27 13:42:02 njin-K8NF4G-SATA2 kernel: [  494.895093] [drm] nouveau 
0000:00:05.0: PGRAPH - ERROR nsource: FORMAT_EXCEPTION nstatus: INVALID_STATE 
BAD_ARGUMENT PROTECTION_FAULT
  Jul 27 13:42:02 njin-K8NF4G-SATA2 kernel: [  494.895110] [drm] nouveau 
0000:00:05.0: PGRAPH - ch 3 (0x000db000) subc 6 class 0x009f mthd 0x0308 data 
0x00180042
  
  This is the first time that I can observe this behavior in an installed
  system, before it was afflicting only the live session or ubiquity-dm.
  
  Screenshot and syslog attached
  
  Thanks
  Fabio
