I've been running e17 under Xubuntu 14.04 on my old Dell D810 laptop for
just under a year.

No serious problems until two days ago the screen suddenly went black.
Normally this is the screensaver, after 15 mins inactivity, but in this
case I was in the middle of typing. I could not find any keystroke to
re-awaken the screen. The system was apparently still active, as it was
downloading a file I had requested, so I waited until the disk ligh
stopped flashing, then held down the power button to force a shutdown.

When I restarted, the screen prompted me for Ubuntu in the normal way,
let me log in, and started Enlightenment...and then went black as
before. I forced power-off and left it.

The day before this happened, I had moved the mouse to wake up the
machine from the screensaver in the normal way, and got an unusual
pop-up message that I had woken the screensaver too quickly, and did I
want to change some settings (that it described in terms I did not
recognise). I clicked No and carried on working (so I don't have a
screenshot of the message, sorry).

Today I powered up the machine normally and worked perfectly OK for
about 2 hours. I went to get coffee and came back to find the screen
black and irretrievable again.

Before I start investigating hardware...does anyone recognise these
symptoms and have any advice? I checked the temperature sensor and fan
but they seem to be working correctly. The battery in all cases was well
charged, or the power was plugged in.

It may be nothing to do with E and the screensaver, but I'd like to
eliminate that before I start digging deeper.
