Hey, I just spend a long time debugging this. And suddenly it hit me. In dapper I was using fglrx, in the upgrade to edgy this was removed. Now that I reinstalled fglrx in edgy, the problem is solved...
I guess you can close this one up, sinse it's a freak problem unlikely to occur for others. The problem never was gnome-power-manager , /var/log/messages always stated: gnome-power-manager: (finalbeta) DPMS blanking screen because the lid has been closed on ac power. Sry for your time. -- edgy: closing laptop screen ends my session (should give blanck screen) https://launchpad.net/bugs/61175 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
