Richard,
I turned off “Activate screensaver when computer is idle” in
System-Preferences-Screensaver.
This fixed the blanking problem.

You should be able to login to a failsafe X session and then start g-s however you want.

now, that i thought some more about it, its kind of weird i had never experienced these blank screens (or attempts for it) on my machine at work – running in a virtualbox container – though i am using F11 this way since close to one week after release. Maybe vista (cough) or virtualbox do someting to prevent this. ACPI’s, etc. working fine. Some clues what to check for are indeed welcome …

Start an X session with no desktop environment, just a window manager; or alternatively just an xterm.

In your xterm run gnome-session or gdb gnome-session or what have you.

I’m not sure if it’s related, but apart from the screen blanking when I’m watching a movie, neither time-triggered blank nor suspend seem to work for me. I reported this in red hat bugzilla:

sorry, I cannot offer any gnome-session debugging experience whatsoever here. hopefully someone can fill the void. Actually, I just wanted to say that after trying out so much stuff out there in the wild of forums and the like, its great you took so much effort to find the most comprehensive answer to the root of the problem. I suffered from this issue greatly since upgrading to F11 (actually it just happened while writing – as in typing- this post).

Just for the record for anyone reading, the Fedora bug report for this is https://bugzilla.redhat.com/show_bug.cgi?id=501601 .

I’d thought I was going crazy! It’s a really difficult bug to describe, I’m glad I happened upon your blog (although if you have a bug report for following this issue, that’d be brilliant!).

I don’t know of a way to replace the gnome-session process, but if you’ve got an easily reproducible test, and you think the problem’s in gnome-session, have you considered trying a git (or subversion if the bug’s really old) bisect to see what might’ve caused it? It’s a long shot, but you can quickly see whether it’s likely to succeed or not by rolling back gnome-session. If 2.24 doesn’t feature the problem, then it’s definitely worth bisecting…
