Touchscreen is not a "wake from suspend" source, so as you suggest it
didn't get to suspend to make this trouble. Answer for that is in the X
world, giving an easy way to get into suspend immediately if you know it
goes to your bag.
| btw: are there hooks to actions to be done on suspend/resume and a way
to
| determine if the resume was caused by phone/pwrbutton or something else?
cat /sys/devices/platform/neo1973-resume.0/resume_reason
as I mentioned gives you the resume reason easily enough if you have
current U-Boot. I think Carsten plans to have it done by D-Bus to talk
to this daemon. But I am a bit doubtful this userspace-centric way is
going to be enough.
