I have the same problem. I don't think it's good for the monitor, so I'll disable power saving for the time being.
My monitor is a "DELL P2411H" (from Xorg.0.log), and the X driver is Radeon. The monitor is connected via the DVI cable. I don't have the problem when I use fglrx, the proprietary AMD driver. Searching the Redhat bugzilla I assume the equivalent bug is this: https://bugzilla.redhat.com/show_bug.cgi?id=714334 (the link in Tim Cuthbertson's bug description is missing the id) ** Bug watch added: Red Hat Bugzilla #714334 https://bugzilla.redhat.com/show_bug.cgi?id=714334 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/910672 Title: [REDWOOD] dell U2410 monitor repeatedly turns itself on and off when suspended To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/910672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
