Fails with: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 137 (DPMS) Minor opcode of failed request: 6 (DPMSForceLevel) Serial number of failed request: 27 Current serial number in output stream: 27 Three patches from upstream fix it for me.

And now I can't hit this bug anymore. Weird. Maybe it was a bug in X after all. Closing. -_-
