https://bugs.freedesktop.org/show_bug.cgi?id=76483 --- Comment #25 from Karl Schendel --- That fixed the garbled display. The monitor off/on thing is weird. When I was trying to get 3.14 to work (before discovering this bug report), I tried the nvidia binary driver and got the same flash off/on thing. However, dpms-off was working in 3.6.3, which I unfortunately don't have lying around any more. It seems strange that the monitor would break in this manner, so I guess the 3.6.x driver was doing something to work around the monitor's response. (Also, the monitor-off screensaver works when I am in OS/X.) I can get a log to verify if you like, later today. If there's anything I can get from 3.6 to see if it's doing something different, let me know; I'm sure I can find and build a 3.6 sometime in the next day or two if necessary. At least it's going in the right direction - thanks! -- You are receiving this mail because: You are the assignee for the bug.
