Comment 13 for bug 484186

Gnome-settings-daemon is receiving two input events in a very short amount of time from the kernel. The input events are basically fn-F7, or "change my display output configuration". Unfortunately, these events are coming in reverse order, so the timestamps go backwards. The input timestamps are fed to the xserver, which evaluates the first just fine, and then errors out on the second due to the timestamp warping. What we need to do is either:

a. Have g-s-d detect warped timestamps and refuse to continue
b. Have g-s-d detect warped timestamps and set a the timestamp to the previous + 1

I'm testing out a. right first since it's the cleaner approach. I don't think there will be any issues with it, but you never know. I'll test out b. if a. has issues.
