Apologies for not updating this ticket. I've been running fedora for the last few releases. The fedora bug (https://bugzilla.redhat.com/show_bug.cgi?id=714334) has been fixed for a while now.
Given that it originally occurred on both, hopefully it's just an an upstream fix that ubuntu will get if you've merged xorg-x11-drv-ati, version 6.14.3. I'm afriad I can't test it out though, as I no longer run ubuntu - perhaps one of the other affected users can test? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/910672 Title: [REDWOOD] dell U2410 monitor repeatedly turns itself on and off when suspended Status in “linux” package in Ubuntu: Incomplete Bug description: Originally reported in fedora's bugtracker here: https://bugzilla.redhat.com/process_bug.cgi But I've since moved to ubuntu. The bug is still present, so I thought I should report it here as well. Description of problem: Monitor does not standby / turn off, but instead keeps entering and leaving standby. How reproducible: Always. Steps to Reproduce: 1. xset dpms force off Actual results: The monitor goes dark (but not off). A few seconds later, the monitor shows me an "entering power save mode" message and then actually turns off the backlight. A second or so after that, the monitor backlight is turned on again, with a DVI cable symbol in the top left corner as if a cable had just been plugged in (my computer is connected to my monitor with DVI, and nothing else is plugged into the monitor). Seconds later, it shows the message about entering power save mode. This repeats indefinitely. This also happens using the normal power saving settings, and leaving my computer alone for 5 minutes. Expected results: Monitor should turn off / enter standby until I wake it ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: linux-image-3.0.0-14-generic 3.0.0-14.23 ProcVersionSignature: Ubuntu 3.0.0-14.23-generic 3.0.9 Uname: Linux 3.0.0-14-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
