--- Comment #24 from howaboutsynergy at pm.me ---
actually the variation is strictly due to the time I spent until I turned on
the monitor! if I don't turn it on, it will still -110
the only problem is that it keeps retrying for about 220 seconds(while the
monitor is still off):

looking at the caller stack, it's for different callers, but it gives up after
13 such attempts, apparently (unless that's the time the video card went to
sleep again, since I went away from the computer - monitor was still turned
off)
