Thanks for the report. Could you kill GPM right after loading into gnome and see if the screen blanking happens later on in the session?
command in terminal: killall gnome-power-manager I'm experiencing the same bug and wanted to see if it is related to: http://blogs.gnome.org/hughsie/2009/07/30/accidental-blanking-and-gnome-power-manager/ bug #387529 commit: http://git.gnome.org/cgit/gnome-power-manager/commit/?id=b5cf34d4b9861ab916a3ff74a2a08093ccb75b9f If the bug remains after killing GPM, it appears to be related to the above blog posting in that there is a bug in gnome-session.
