Hum, I looked at your bug report and I don't see where the signals were mentioned. What kind of monitor was it? I am interested as an electronics tech on how this could have happened. I have seen many monitors get driven way out of their scan ranges without affecting anything other than my eyes as I try to figure out how what is happening. It is interesting how a monitor will scream if you scan it at a rate that only displays the middle 1/10th of the screen. Also what are the scan rate limits of the monitor? I am thinking that this is more of a coincident like the time that my monitor died as I was making some changes to the system. A cold solder connection went at the same time. FWIW, I really doubt that the bug can be worked on with the details you provided. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
